Abstract

PURPOSE:To execute positioning precisely and to use only a pair of switches by converting oscillation due to a shift lever into displacement in the circumferential direction of a horizontal shaft and that in the axial direction. CONSTITUTION:When the shift lever 3 is vertically oscillated, the lever 3 is oscillated around the horizontal shaft 9. When the lever 3 is horizontally oscillated, the center of the rotation is changed to a check ball 23 arranged on the lower end of a vertical shaft 5. Namely, the vertical and horizontal oscillation of the lever 3 are divided/converted into displacement in the circumferential direction of the horizontal shaft 9 and that in the axial direction. Consequently, positioning can be precisely attained. The precise operation moves an arm 35 on one end 15 of the horizontal shaft 9 precisely to open/close a contact point of a switch 37.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to an improvement of a shift device in a vehicle power transmission system.

[Prior Art 1] A shift device for shifting gears, etc. in a vehicle's power transmission system uses two-dimensional rocking in the X-axis direction and Y-axis direction of a vertical shaft directly connected to a shift lever. Many of them were mechanical type, in which the displacement of a speed change gear, etc. was directly changed by the so-called rocking displacement between the horizontal axis direction and the vertical axis direction.

In recent years, devices have been proposed in which this switching operation is performed via an electrical device.

In this case, two sets of switches are provided, one switch corresponds to positioning by swinging in the horizontal axis direction, and the switch used corresponds to positioning by swinging in the ltJ axis direction. The electric drive device is configured to perform several types of shifts depending on the operation of the shift lever by opening and closing the contacts of the switch.

[Problems to be Solved by the Invention] However, such a shift device has a configuration in which two sets of switches are combined, one corresponding to vertical displacement and the other corresponding to lateral displacement. Naturally, the switch circuit also becomes complicated.

Therefore, the present situation is that this shift device requires extra costs in the design and manufacturing stages, and is also disadvantageous in terms of maintenance and inspection during the use stage.

[Objective of the Invention] Therefore, the present invention aims to provide a shift device in which a selective displacement mechanism of the shift device is devised so that the displacement operation of the shift lever achieves reliable positioning with little play or rattling, and one set of switches is sufficient. purpose.

[Structure of the Invention] In order to achieve the above object, the present invention provides a shift lever.
A vertical shaft connected to the vertical shaft, a horizontal shaft mounted almost orthogonally to the vertical shaft, and a swing displacement operation that is performed by selecting multiple positions of the vertical shaft in the vertical direction and the horizontal direction using the shift lever. The shift device is provided with a positioning means that performs positioning by converting the displacement into a circumferential displacement and an axial displacement of the horizontal shaft, and a switch that opens and closes a contact in response to the movement of the shaft.

[Function of the Invention] The shift device of the present invention is configured as described above, and each swing displacement operation of the shift lever in the horizontal direction and the vertical direction has a different 1f center of motion in each swing direction, and the movement is divided into circumferential displacement and axial displacement of the horizontal shaft near the center of swing for positioning, resulting in compact and reliable operation.

Since the switch is operated by the reliable movement of the horizontal shaft with less play or rattling, it is possible to perform a shift operation with a single set of small switches.

Therefore, the switch and circuitry are greatly simplified, which is very advantageous in terms of design, manufacture and use.

[Embodiment] An embodiment of the shift device of the present invention will be described below with reference to the drawings of FIGS. 1 to 3.

A shift device 1 for shifting a transmission gear (not shown), which is part of a power transmission system of a vehicle, is provided on the floor to the side of a driver's seat (not shown).

The shift device 1 has an extended vertical shaft 5 connected to the lower part of the shift lever 3, and a short rectangular cylinder 7 is sandwiched near the center of the compressed shaft 5 in the form of dividing the vertical shaft 5 into upper and lower parts. has been done.

A horizontal shaft 9 facing in the vehicle width direction is disposed in the rectangular cylinder 7 so as to pass through the vertical shaft 5 at a substantially right angle.
It is pivotally supported by pin 11.

Both ends of the horizontal shaft 9 extend through the left and right side walls of the bracket 13 of the shift device 1 fixed to the floor of the vehicle, and are rotatably and slidably supported by the side walls of the bracket 13. has been done.

In this embodiment, four annular grooves 17 are carved close to each other on the outer periphery of one end 15 of the horizontal shaft 9, and a check ball machine #419 with a spring is engaged with these annular grooves 17.
are mounted on the side wall of the bracket 13, and these act as a lateral positioning device 2 for the axial movement of the lateral shaft 9.
1.

Also at the lower end of the vertical shaft 5 extending below the rectangular cylinder 7,
A check ball 23 with a spring is attached.

The vertical shaft 5 shifts to horizontal shift 1 aft 9 by operating the shift lever 3.
The center of rotation is a rocking motion along the direction of vehicle travel, that is, vertical rocking.

At this time, the check ball 23 at the lower end of the vertical shaft l-5 is abutted and guided by the arcuate groove 25, and the base IP71-
The device is held only on the circular arc when it swings vertically on a vertical plane.

Therefore, when the shifter 1-lever 3 is moved one position in the horizontal direction, the check ball 23 provided at the lower end of the vertical shaft 1-5 swings as the center of rotation.

Also, everyone at the center and both ends of this arcuate groove 25! - An arcuate shape with four enlarged holes like this one with enlarged recesses for fixing.
A longitudinal positioning plate 27 engraved with 5 is mounted below the bracket 13.

In the rectangular tube body 7, the horizontal shafts 1-9 extend to near the front wall surface of 4 (the tip 29 of the bottle 11 made of wood bark is a bracket).

Then, in order to engage the pin tip 29 in response to the circumferential and axial displacements of the horizontal shaft 9, a groove width that is approximately equal to the pin tip diameter is cut out in a shape with comb teeth facing each other from above and below. A grooved plate 33 with grooves is attached to the inner surface of the front wall of the bracket 13.

Furthermore, an arm 3 is attached to the end surface of one end 15 of the horizontal shaft 9.
5 is attached, and the tip of the arm 35 is shaped to protrude horizontally forward, and a switch 37 is provided in such a position that the tip of the arm 35 engages to open and close the contact.

In this embodiment, the switch 37 has 8 circuits and 16 contacts, and is mounted on a bracket 39 projecting from the side of the case 13. The contacts are arranged so that the arm 35 opens and closes the contacts in correspondence with the respective positioning points of circumferential displacement and axial displacement of the horizontal shaft 1-9.

In the shift iai configured as above, the movement when the shift lever 3 is operated will be described.

First, move the shift lever 3 vertically (horizontal direction shown in Figure 2).
When it is swung, it oscillates around the horizontal shaft 9. The check ball 23 at the lower end of the vertical shaft 5 moves while being guided by the arcuate groove 25 of the vertical positioning plate 27, and is positioned in an enlarged recess in the arcuate groove 25.

Next, when the shift lever 3 is swung in the horizontal direction (the left-right direction in FIG. 1), the center of rotation in this case is the check ball 23 at the lower end of the vertical shaft 5, as described above. Then, the horizontal shaft 9 in the middle of the vertical shaft 5 is moved in the axial direction by a stroke that is a fraction of the swing direction of the shift lever 3 in the VJ direction, and is positioned at four points during the axial movement stroke by the horizontal positioning device 21. be done.

That is, each swing operation in the vertical and lateral directions by the shift lever 3 results in a circumferential displacement accompanied by three-point positioning of the horizontal shaft 9 and an axial displacement accompanied by four-point positioning. The dynamic center is divided and transformed under different conditions.

The positioning means to be divided and converted are the horizontal shaft 9, the horizontal positioning device 21, and the vertical positioning plate 27.
and a check ball 23.

And the extending tip 29 of the bin 11 that pivots the horizontal shaft 9
By the engagement of the grooved plate 33 with the horizontal shaft (-9), the movement of the divided and positioned two directions is more reliably regulated.

At the same time, excessive movement, insufficient movement, and movement that could lead to malfunction when the shift lever 3 is driven in the vertical and horizontal directions are reliably regulated to enable only accurate shifting.

This reliable movement ensures that the arm 3 at one end 15 of the horizontal shaft 9
The contacts of the switch 37 are opened and closed by accurately moving the switch 5. Furthermore, since the structure is as described above, there are extremely few unnecessary connecting parts that may cause play or rattling.

[Effects of the Invention] As is clear from the above description, according to the shift device of the present invention, the vertical and lateral shifting movements of the shift lever are performed around the circumference of one horizontal shaft near the center of rotation. Positioning is performed by dividing the displacement into directional displacement and axial displacement.
Although the movement is small, it is extremely clear. Moreover, as mentioned above, due to the structure, there is almost no play or wobbling.

As a result, it is possible to electrically drive a multi-stage shift I'-operation with one set of switches, and the configuration of the switch itself and the circuit can be significantly simplified compared to the case of two sets of switches.

Therefore, it is possible to reduce costs in terms of installation and production of electric circuits, while greatly reducing failures in use and making maintenance and inspection extremely easy.
