Abstract

PROBLEM TO BE SOLVED: To securely prevent a vehicle from unexpectedly starting, when idling stop control is ended and an engine is started again.SOLUTION: In a vehicle including a manual transmission, when a select lock mechanism is operated, select operation to first and second gear speed select positions and a reverse selection position of a select member is inhibited. When idling stop control is performed, that is, when a predetermined engine stop condition is satisfied, the engine is automatically stopped, and when predetermined engine start condition is satisfied, the engine is automatically started, it is restricted that the select member is moved to the first and second gear speed selection positions and the reverse selection position, when the engine is stop-controlled. Thereby, it is possible to surely prevent the engine from automatically starting and the vehicle from unexpectedly starting, during idling stop control, in a state where the first gear speed, the second gear speed or reverse gear selection is established.

  By the way, when idling stop control is performed on a vehicle equipped with a manual transmission, if the driver in-gears the first gear or reverse gear during idling stop control, the depression of the clutch pedal is detected and the engine is automatically restarted. When starting, the vehicle may take an unexpected start.

  To avoid this, if the driver is in gear to the first gear or reverse gear during idling stop control, confirm that the clutch pedal is fully depressed and the start clutch is disengaged. After that, it is conceivable to restart the engine. However, when such control is performed, the timing at which the engine is restarted differs depending on whether in-gear or not in-gear, as will be described in detail in the “Description of Embodiments” section of this specification. Thus, there is a problem that the driver feels uncomfortable, or the timing at which the engine is restarted is delayed and the vehicle is prevented from starting smoothly.

  The present invention has been made in view of the above circumstances, and an object thereof is to reliably prevent the vehicle from starting unexpectedly when the idling stop control is finished and the engine is restarted.

  In order to achieve the above object, according to the first aspect of the present invention, a select line extending along a select direction and a plurality of select positions arranged at predetermined intervals on the select line with respect to the select direction. In a manual transmission that shifts by moving the shift lever along a pattern having a plurality of shift lines extending in both or one of the orthogonal shift directions, the shift lever moves along the select line. And a lock member that restricts movement of the select member to a reverse select position and a predetermined forward shift stage select position by engaging with the select member. When in the 1 position, the lock member is in the select position for all the select members. When the lock member is in the second position, the lock member restricts the select member from moving to the reverse select position, and when the lock member is in the third position, the lock member is allowed to move. The lock member is a select lock device in a manual transmission that restricts movement of the select member to the predetermined forward shift position select position, and automatically stops the engine when a predetermined engine stop condition is satisfied, Engine start / stop means for automatically starting the engine when a start condition is satisfied, and when the engine start / stop means controls the engine to stop, operating the lock member to the third position; A select lock device for manual transmission has been proposed. .

  According to the invention described in claim 2, in addition to the configuration of claim 1, there is proposed a select lock device in a manual transmission, wherein the predetermined engine starting condition is depression of a clutch pedal. The

  According to a third aspect of the present invention, in addition to the configuration of the first or second aspect, when the lock member is in the third position, the lock member is in the reverse select position. A select lock device in a manual transmission is proposed, which is characterized by restricting movement of the manual transmission.

  According to the invention described in claim 4, in addition to the configuration of claim 3, the predetermined forward shift stage select position is a position for selecting a start shift stage, and the neutral position of the shift lever is the position of the shift lever. A forward shift stage select position different from the starting shift stage is disposed between the neutral position and the reverse select position, and is disposed closer to the reverse select position than a predetermined forward shift stage select position. A select lock device in a manual transmission is proposed.

  The select lock cam 22 of the embodiment corresponds to the select member of the present invention, the lock arm 24 and the lock pin 28 of the embodiment correspond to the lock member of the present invention, and the electronic control unit U of the embodiment is This corresponds to the engine start / stop means of the present invention.

  According to the configuration of the first aspect, when the shift lever is moved along the select line, the select member is moved to a plurality of select positions, and the shift lever is moved toward the shift position corresponding to each select position. it can. When the lock member that engages the select member to restrict the select member from moving to the reverse select position and the predetermined forward shift position select position is in the first position, the select member moves to all select positions. When the lock member is in the second position, the select member is restricted from moving to the reverse select position. When the lock member is in the third position, the select member is moved to the predetermined forward shift stage select position. Since movement is restricted, the reverse shift stage select lock and the predetermined forward shift stage select lock can be realized with a common select lock device, and the select lock device is reduced in size, weight and cost. Down is possible.

  In addition, the engine is automatically stopped when a predetermined engine stop condition is satisfied, and when performing idling stop control for automatically starting the engine when a predetermined engine start condition is satisfied, the lock member is By operating to the third position and restricting the selection member from moving to the predetermined forward shift stage select position, the engine is automatically started with the forward shift stage established during idling stop control, and the vehicle is expected. It is possible to reliably prevent the vehicle from starting off.

  According to the second aspect of the present invention, it is ensured that the forward shift speed is not established when detecting the depression of the clutch pedal and starting the stopped engine, so that the clutch pedal is fully depressed. Thus, it is possible to start the engine at the beginning of depression of the clutch pedal without confirming that the starting clutch is disengaged, thereby preventing the driver from feeling uncomfortable and enabling the vehicle to start quickly.

  According to the third aspect of the present invention, when the lock member is in the third position, the lock member can not only restrict the movement of the select member to the predetermined forward shift stage select position but also move to the reverse select position. Can also be regulated.

  According to the fourth aspect of the present invention, even when the shift member restricts the movement of the shift lever to the start gear position and the reverse select position by the lock member, the shift lever is in the neutral position and the start gear stage. Since it is possible to move in the select direction between the forward shift stage select position different from the select position, it is possible to minimize the uncomfortable feeling that the shift lever is restrained so as not to move.

First embodiment

  Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 shows a shift pattern of a manual transmission with 6 forward speeds and 1 reverse speed. The shift pattern for guiding the movement of the shift lever 11 operated by the driver includes a select line 12 extending in the left-right direction, a 1-2 speed select position provided on the select line 12, a 3-4 speed select position, 5 -It is composed of four shift lines 13, 14, 15, 16 that branch in the front-rear direction from the 6th speed select position and the reverse select position.

  After the shift lever 11 is selected on the select line 12 and moved to the 1-2 speed select position, if the shift line 13 is shifted forward, the first gear is established, and if the shift is shifted backward, the second speed is established. A gear position is established. After the shift lever 11 is selected on the select line 12 and moved to the 3-4 speed select position, the 3rd speed is established when the shift line 14 is shifted forward, and the 4th speed is established when the shift is operated backward. A gear position is established. After the shift lever 11 is selected on the select line 12 and moved to the 5-6th speed select position, if the shift line 15 is shifted forward, the fifth gear is established, and if the shift is operated backward, the sixth speed is selected. A gear position is established. After the shift lever 11 is selected on the select line 12 and moved to the reverse select position, the reverse shift stage is established when the shift line 16 is shifted backward.

  If the vehicle is traveling forward at a speed higher than a predetermined speed and shift-changed to the reverse gear, there is a problem that noise is generated when a gear in the transmission is engaged, or a shock is transmitted to the vehicle body. A reverse select lock mechanism is provided so that the reverse select position cannot be operated.

  For example, to shift down to the fourth speed when the vehicle is traveling at the fifth speed, for example, the shift lever 11 is moved backward from the fifth speed shift position to the 5-6 speed select position, Subsequently, the shift lever 11 is operated to the left from the 5-6 speed select position to move to the 3-4 speed select position, and then the shift lever 11 is operated backward from the 3-4 speed select position to shift to the 4th speed. Must be moved to a position. At this time, if the shift lever 11 does not stop at the 3-4 speed select position and momentarily reaches the 1-2 speed select position, and the shift lever 11 is operated rearward as it is, the 4th speed gear stage is originally established. There is a case where the second gear is established by mistake.

  In FIG. 2, when the vehicle is traveling at a speed of 5 km with a speed of 100 km / h and an engine speed of a, the engine speed is b if the gear is normally shifted down to a speed of 4 with a gear speed. When the gear is shifted down to the high gear, the engine speed reaches c, which may exceed the overrev limit and adversely affect the durability of the engine. As will be described later, Bkm / h on the horizontal axis is the vehicle speed at which the 1-2 speed select lock mechanism operates.

  For this reason, when the vehicle speed is equal to or higher than a predetermined value, it is necessary to provide a 1-2 speed select lock mechanism so that the shift lever 11 cannot be operated from the 3-4 speed select position to the 1-2 speed select position. .

  FIG. 3 shows ON / OFF of the solenoid that operates the reverse select lock mechanism and the 1-2 speed select lock mechanism. In the low vehicle speed range from 0 km / h to Akm / h, the reverse select lock mechanism and 1 Since it is not necessary to operate the second speed select lock mechanism, the energization to the solenoid is turned off. In the medium vehicle speed range of vehicle speeds Akm / h to Bkm / h, it is necessary to operate the reverse select lock mechanism, and it is not necessary to operate the 1-2 speed select lock mechanism, so the solenoid is turned on at the first voltage. . In a high vehicle speed range where the vehicle speed is Bkm / h or higher, it is necessary to operate both the reverse select lock mechanism and the 1-2 speed select lock mechanism, so the solenoid is turned on at the second voltage.

  In this way, if the reverse select lock mechanism and the 1-2 speed select lock mechanism are configured by a common mechanism that operates with a single solenoid, the size can be reduced, the weight can be reduced, and the cost can be reduced.

  When performing engine idling stop control, the engine is stopped after confirming that the shift lever 11 is in the neutral position. However, the driver operates the shift lever 11 during idling stop control. If the first speed gear and reverse gear are established in advance and the engine is started with the clutch not fully depressed, the vehicle may start unexpectedly.

  In the present embodiment, the select lock mechanism is operated during idling stop control to prevent the vehicle from starting unexpectedly.

  As shown in FIG. 4, a U-shaped select lock cam 22 is fixed to a select shaft 21 connected to the shift lever 11 via a cable or a link (not shown). The select shaft 21 rotates in conjunction with the operation of the shift lever 11 to the 1-2 speed select position, the 3-4 speed select position, the 5-6 speed select position, and the reverse select position, and stops at these four select positions. . In FIG. 4A, the select lock cam 22 is most rotated clockwise at the 1-2 speed select position, from which the 3-4 speed select position, the 5-6 speed select position, and the reverse select position are at a predetermined angle. Each is rotated counterclockwise. A lock arm 24 pivotally supported by a pivot 23 provided in a mission case (not shown) is urged upward in the figure by a return spring 25 disposed on the outer periphery of the pivot 23. An output rod 27 extending downward from a solenoid 26 fixed to the transmission case contacts the upper surface of the lock arm 24. The U-shaped select lock cam 22 is formed with a first protrusion A having a high radial protrusion height and a second protrusion B having a low radial protrusion height. A third protrusion C protruding toward the lock cam 22 is formed.

  As shown in FIG. 5, the electronic control unit U that performs idling stop control and select lock control is based on signals from the vehicle speed sensor Sa, the engine speed sensor Sb, the shift position sensor Sc, and the clutch switch Sd. The operation of the injection control device 33, the starter motor 34 and the solenoid 26 is controlled.

  Next, the operation of the embodiment of the present invention having the above configuration will be described.

  FIG. 4A shows a state in which the vehicle speed detected by the vehicle speed sensor Sa is in a low vehicle speed region of 0 km / h to Akm / h and the select lock is released. At this time, the solenoid 26 controlled by the electronic control unit U is turned off and the output rod 27 is retracted upward, and the lock arm 24 is retracted upward following the output rod 27 by the elastic force of the return spring 25. . In this state, the third protrusion C of the lock arm 24 does not engage with either the first protrusion A or the second protrusion B of the select lock cam 22, and the select lock cam 22 and the select shaft 21 are selected for the 1-2 speed select. The position can be rotated to any of the 3-4 speed select position, the 5-6 speed select position, and the reverse select position, and the select lock is released.

  FIG. 4 (B) shows a state where the vehicle speed is in the medium vehicle speed range of Akm / h to Bkm / h, the reverse select lock is activated, and the 1-2 speed select lock is released (reverse select lock state). Yes. At this time, the solenoid 26 is turned on by the first voltage, the output rod 27 protrudes downward by one step, and the lock arm 24 rotates downward against the elastic force of the return spring 25.

  In this state, the third protrusion C of the lock arm 24 does not engage with the short second protrusion B of the select lock cam 22, but the tall first protrusion A is in the lock arm 24 in the 5-6 speed select position. The third projection C is engaged to restrict the counterclockwise rotation of the select lock cam 22 from the 5-6 speed select position to the reverse select position. As described above, in the reverse select lock state, the shift lever 11 that is interlocked with the select lock cam 22 is shown in FIG. 1 in order to restrict the rotation of the select lock cam 22 from the 5-6 speed select position to the reverse select position. Locked to the 6th speed select position and unable to move to the reverse select position, the establishment of the reverse gear is prevented.

  At this time, the short second protrusion B of the select lock cam 22 does not engage with the third protrusion C of the lock arm 24, so that the shift lever 11 is in the 1-2 speed select position, the 3-4 speed select position, and the 5- The operation can be performed at any of the 6th speed select positions, and the establishment of the 1st speed to 6th speed can be performed without any trouble.

  FIG. 4C shows a state where the vehicle speed is in a high vehicle speed range of Bkm or higher and both the reverse select lock and the 1-2 speed select lock mechanism are operated (1-2 speed select lock state). At this time, the solenoid 26 is turned on by the second voltage, the output rod 27 protrudes downward in two steps, and the lock arm 24 further rotates downward against the elastic force of the return spring 25.

  In this state, the third protrusion C of the lock arm 24 can be engaged not only with the tall first protrusion A of the select lock cam 22 but also with the short second protrusion B, and in the 3-4 speed select position. The second protrusion B of the select lock cam 22 engages with the third protrusion C of the lock arm 24 to rotate the select lock cam 22 in the clockwise direction from the 3-4 speed select position to the 1-2 speed select position. regulate. Thus, in the 1-2 speed select state, the shift lever 11 interlocked with the select lock cam 22 is used to restrict the rotation of the select lock cam 22 from the 3-4 speed select position to the 1-2 speed select position. 1 is locked at the 3-4 speed select position and cannot move to the 1-2 speed select position, and the establishment of the 1st speed shift stage and the 2nd speed shift stage is prevented.

  When the select lock cam 22 rotates counterclockwise, the first protrusion A engages with the third protrusion C of the lock arm 24 at the 5-6 speed select position. The establishment of the reverse gear is also prevented. Therefore, in the 1-2 speed select lock state, the select lock cam 22 can be operated only at the 3-4 speed select position and the 5-6 speed select position, and only the establishment of the 3rd speed to 6th speed is allowed. The

  As described above, according to the present embodiment, the reverse select lock mechanism and the 1-2 speed select lock mechanism are configured by a common mechanism that is operated by a single solenoid 26, thereby reducing the size and weight. And cost reduction.

  Next, the control of the select lock mechanism accompanying the idling stop control will be described based on FIG. 6 and FIG.

  FIG. 6 shows a select lock control routine at idling stop. First, a fail determination is made in step S1, and if any failure occurs, the solenoid 26 is turned off in step S8 to prohibit the operation of the select lock mechanism. .

  If no failure has occurred in step S1 and idling stop control is not being performed in step S2, the vehicle speed detected by the vehicle speed sensor Sa in step S3 is zero and the vehicle is stopped. In step S4, the shift position sensor is detected. When the shift position detected by Sc is neutral, the clutch switch Sd is OFF in step S5 and the driver is not stepping on the clutch pedal, it is determined that the condition for the idling stop control is satisfied, and in step S6, the fuel injection control device is established. The engine is stopped by shutting off the fuel supply by 33 and idling stop control is executed. In step S7, the solenoid 26 is turned on at the second voltage to activate the select lock mechanism.

  If idling stop control is already being performed in step S2, the solenoid 26 is turned on with the second voltage in step S7 to activate the select lock mechanism. If at least one of the conditions of Step S3, Step S4, and Step S5 is not satisfied, the solenoid 26 is turned off in Step S8 and the operation of the select lock mechanism is prohibited without executing the idling stop control.

  FIG. 7 shows a select lock release control routine at the time of idling stop. First, a fail determination is made in step S11. If any failure occurs, the solenoid 26 is turned off in step S16 to prohibit the operation of the select lock mechanism. To do. If no failure has occurred in step S11 and idling stop control is not being performed in step S12, the solenoid 26 is turned off in step S16 to prohibit the operation of the select lock mechanism.

  When the idling stop control is being performed in step S12, the solenoid 26 is turned on with the second voltage in step S13 to activate the select lock mechanism. If the driver depresses the clutch pedal in step S14 and the clutch switch Sd is turned on, it is determined that the driver has an intention to start. In step S15, the fuel injection control device 33 starts supplying fuel and the starter motor. 34 is driven to start the engine, and in step S16, the solenoid 26 is turned OFF to release the operation of the select lock mechanism.

  As described above, according to the present embodiment, when the idling stop control is started, the select lock mechanism is operated and in-gear to the first gear, the second gear, and the reverse gear cannot be performed. When the person steps on the clutch pedal, the idling stop control is finished and the engine is restarted, it is possible to reliably prevent the vehicle from starting unexpectedly.

  Conventionally, in order to prevent the vehicle from starting unexpectedly when the idling stop control is finished and the engine is restarted, it was confirmed that the clutch pedal was depressed sufficiently deep in the in-gear state. Thus, by restarting the engine, the vehicle is prevented from popping out due to the disengagement of the starting clutch even if in-gear in the first gear, the second gear, or the reverse gear. Further, since there is no possibility of the vehicle jumping out in the in-gear state, the vehicle can be started quickly by restarting the engine with the clutch pedal depressed slightly.

  As a result, the first switch for detecting the shallow depression of the clutch pedal and the second switch for detecting the deep depression of the clutch pedal are required, which not only increases the number of parts, but also in-gear. There is a problem in that the timing at which the engine is restarted is different depending on whether the driver is not driving, and the driver feels uncomfortable. In addition, when in-gear, the engine is not restarted unless the clutch pedal is depressed deeply, and there is a problem that the start timing of the vehicle is delayed.

  On the other hand, according to the present embodiment, in-gearing is reliably prevented during idling stop control. Therefore, the engine is always restarted simply by depressing the clutch pedal shallowly. Solved.

  It is possible to in-gear from the third gear to the sixth gear that is not select-locked during idling stop control. However, engine stall occurs even if the engine is restarted in in-gear at these gears. There is no risk of the vehicle jumping out.

  While the vehicle is stopped, some drivers have a habit of reciprocating the shift lever 11 in the select direction to confirm that the shift lever 11 is in the neutral position. However, even when the select lock mechanism is activated, Since the shift lever 11 can be moved to the 3-4 speed select position and the 5-6 speed select position existing between the 1-2 speed select position and the reverse select position, There is no sense of incongruity.

Second embodiment

  Next, a second embodiment of the present invention will be described with reference to FIG. In the second and subsequent embodiments, the mechanical configuration of the select lock mechanism is different from that of the first embodiment, and the control is the same.

  In the first embodiment described above (see FIG. 4), the first protrusion A and the second protrusion B are provided on the select lock cam 22 side, and the third protrusion C is provided on the lock arm 24 side. In this embodiment, the positional relationship is switched, the first protrusion A and the second protrusion B are provided on the lock arm 24 side, and the third protrusion C is provided on the select lock cam 22 side.

  In the select lock release state shown in FIG. 8A, the solenoid 26 is turned off and the lock arm 24 is retracted upward following the output rod 27 by the elastic force of the return spring 25. The third protrusion C does not engage with either the first protrusion A or the second protrusion B of the lock arm 24, and the select lock cam 22 is freely rotatable and the select lock is released.

  FIG. 8B shows a state in which the reverse select lock is activated and the 1st-2 select lock is released (reverse select lock state). The solenoid 26 is turned on at the first voltage and the output rod 27 is turned on. The lock arm 24 protrudes downward in stages, and rotates downward against the elastic force of the return spring 25. In this state, the third protrusion C of the select lock cam 22 does not engage with the short second protrusion B of the lock arm 24, but the tall first protrusion A is in the 5-6 speed select position. 22 is engaged with the third protrusion C to restrict the counterclockwise rotation of the select lock cam 22 from the 5-6 speed select position to the reverse select position, thereby preventing the establishment of the reverse gear position.

  FIG. 8C shows a state in which both the reverse select lock and the 1-2 speed select lock mechanism are operated (1-2 speed select lock state). The solenoid 26 is turned on at the second voltage and the output rod 27 is turned on. Protrudes downward in two stages, and the lock arm 24 rotates further downward against the elastic force of the return spring 25. In this state, the third protrusion C of the select lock cam 22 can be engaged with both the first protrusion A and the second protrusion B of the lock arm 24, and the select lock cam from the 5-6 speed select position to the reverse select position. 22 is controlled in the counterclockwise direction, and the select lock cam 22 is rotated in the clockwise direction from the 3-4 speed select position to the 1-2 speed select position. Establishing the stage and the reverse shift stage is prevented.

  Also according to the second embodiment, it is possible to achieve the same function and effect as those of the first embodiment described above.

Third embodiment

  Next, a third embodiment of the present invention will be described with reference to FIG.

  In the first embodiment described above (see FIG. 4), the lock arm 24 is swingably disposed between the solenoid 26 and the select lock cam 22. However, in the third embodiment, the solenoid 26 and the select lock are arranged. A lock pin 28 is slidably disposed between the lock cams 22. The lock pin 28 slidably penetrates the mission case 29 and is biased upward by the return spring 25. The upper end of the lock pin 28 abuts against the output rod 27 of the solenoid 26, and the third protrusion C at the lower end is The select lock cam 22 faces the first protrusion A and the second protrusion B so as to be engageable with each other.

  In the select lock release state shown in FIG. 9A, the solenoid 26 is turned OFF, and the lock pin 28 follows the output rod 27 by the elastic force of the return spring 25 and retreats upward. The three protrusions C do not engage with either the first protrusion A or the second protrusion B of the select lock cam 22, and the select lock cam 22 can freely rotate to release the select lock.

  FIG. 9B shows a state where the reverse select lock is activated and the 1st-2 select lock is released (reverse select lock state). The solenoid 26 is turned on at the first voltage and the output rod 27 is turned on. The lock pin 28 protrudes downward against the elastic force of the return spring 25. In this state, the third protrusion C of the lock pin 28 does not engage with the short second protrusion B of the select lock cam 22, but the tall first protrusion A is in the 5-6 speed select position. The third projection C is engaged to restrict the counterclockwise rotation of the select lock cam 22 from the 5-6 speed select position to the reverse select position, thereby preventing the establishment of the reverse gear position.

  FIG. 9C shows a state in which both the reverse select lock and the 1-2 speed select lock mechanism are operated (1-2 speed select lock state). The solenoid 26 is turned on at the second voltage and the output rod 27 is turned on. Protrudes downward in two stages, and the lock pin 28 protrudes further downward against the elastic force of the return spring 25. In this state, the third protrusion C of the lock pin 28 can be engaged with both the first protrusion A and the second protrusion B of the select lock cam 22, and the select lock cam from the 5-6 speed select position to the reverse select position. 22 is controlled in the counterclockwise direction, and the select lock cam 22 is rotated in the clockwise direction from the 3-4 speed select position to the 1-2 speed select position. Establishing the stage and the reverse shift stage is prevented.

  Also according to the third embodiment, the same operational effects as those of the first embodiment described above can be achieved.

Fourth embodiment

  Next, a fourth embodiment of the present invention will be described with reference to FIG.

  In the first embodiment described above (see FIG. 4), the select shaft 21 is rotated in response to the select operation of the shift lever 11, but the select shaft 21 in the fourth embodiment is the shift lever. 11 is slid in the axial direction with respect to the mission case 29 in response to the select operation of 11, and is rotated with respect to the mission case 29 in accordance with the shift operation of the shift lever 11. An interlock member 30 integrally having a select lock cam 22 is fitted on the outer periphery of the select shaft 21 so as to be slidable and relatively rotatable. The interlock member 30 is prevented from rotating with respect to the mission case 29 by a non-rotating mechanism (not shown), and is biased downward by a return spring 32. The shift arm 31 fixed to the select shaft 21 inside the interlock member 30 protrudes outside from a slit formed in the interlock member 30 and engages with a shift fork (not shown).

  Similar to the first embodiment, the select lock cam 22 is formed with a first projection A having a tall height and a second projection B having a short height, which are operated in three positions by a solenoid 26. The arm 24 is formed with a third protrusion C that can be engaged with the first protrusion A and the second protrusion B.

  In the select lock release state shown in FIG. 10A, the solenoid 26 is turned OFF, and the lock arm 24 follows the output rod 27 by the elastic force of the return spring 25 and retracts to the right. The third protrusion C does not engage with either the first protrusion A or the second protrusion B of the select lock cam 22, and the select shaft 21 can freely move up and down, and the select lock is released.
