Characterized in that configured to include.

Between the shift guide groove and the shift finger, a finger engaging groove is inserted into the shift guide groove to allow relative rotation with respect to the manual shaft holder during the rotational movement of the manual shaft holder and to insert the shift finger in a rotatable state. One shift slider can be provided.

The end of the select finger provided in the select lever is formed in a spherical shape,

An end portion of the shift finger provided in the shift lever may be formed in a cylindrical shape.

The shift guide groove and the select guide groove formed in the manual shaft holder may be formed to be opened in the same direction from the manual shaft holder.

The present invention uses a set of worm gears, links and slide structures, respectively, in implementing the select function and the shift function, thereby reducing the number of parts used, and in particular, reducing the number of gears, thereby reducing backlash and improving power transmission efficiency. To achieve an improvement and to make the unit cost of the product low.

2 to 5, an embodiment of the present invention includes a housing (1); A manual shaft (3) installed so as to allow linear sliding movement with respect to the housing (1); The rotary shaft and the linear motion are coupled to the manual shaft 3 so as to be constrained, and a linear select guide groove 5 is provided in the longitudinal direction of the manual shaft 3. A manual shaft holder 9 having an arc-shaped shift guide groove 7; A select lever (13) having a select finger (11) inserted into the select guide groove (5) and having a rotation shaft perpendicular to the axial direction of the manual shaft (3); A select motor 15 mounted to the housing 1; A select gear 17 connected to the rotation shaft of the select motor 15 in a worm gear structure and configured to transmit a rotational force to rotate the select lever 13 around the rotation shaft of the select lever 13; A shift lever (21) having a shift finger (19) inserted into said shift guide groove (7), said shift lever (21) having a pivot axis perpendicular to the axial direction of said manual shaft (3); A shift motor 23 mounted to the housing 1; It is configured to include a shift gear 25 is connected to the rotation shaft and the worm gear structure of the shift motor 23 to transmit the rotational force to rotate the shift lever 21 about the rotation axis of the shift lever 21. .

In other words, in implementing the select function and the shift function, only one pair of worm gears, links and slide structures are used to simplify the power transmission path and minimize the number of parts.

Between the shift guide groove 7 and the shift finger 19, it is inserted into the shift guide groove (7) to allow relative rotation with respect to the manual shaft holder (9) during the rotational movement of the manual shaft holder (9) The shift slider 29 is further provided with a finger engaging groove 27 into which the shift finger 19 is rotatable.

Of course, the shift finger 19 may be configured to be directly inserted into the shift guide groove 7 formed in the manual shaft holder 9 without having the shift slider 29. It would be desirable to have a shift slider 29 as in this embodiment for improvement.

An end of the select finger 11 provided in the select lever 13 is formed in a spherical shape, and the select guide groove of the select finger 11 and the manual shaft holder 9 when the select lever 13 is rotated. 5) It can absorb both relative rotation and linear motion between.

On the other hand, the end of the shift finger 19 provided in the shift lever 21 to be formed in a cylindrical shape, it was configured to be simply inserted into the finger coupling groove 27 of the shift slider (29).

Here, the shift guide groove 7 and the select guide groove 5 formed in the manual shaft holder 9 are formed to be opened in the same direction from the manual shaft holder 9, so that the select finger 11 and the shift Finger 19 is a structure that is inserted into the select guide groove 5 and the shift guide groove 7 in a parallel state in the same direction.

Looking at the operation of the present invention configured as described above with reference to FIG.

When the select motor 15 is driven by the command of the electronic control unit, the select gear 17 is rotated to rotate the select lever 13.

The select finger 11 of the select lever 13 causes the manual shaft holder 9 provided with the select guide groove 5 to generate a relative rotation and linear movement with the select guide groove 5. The manual shaft 3 is rotated about the axial direction.

Accordingly, the manual shaft 3 fixed to the manual shaft holder 9 is rotated to implement the selecting operation.

When the manual shaft holder 9 is rotated by the selecting operation as described above, the shift slider 29, which is in a fixed state, absorbs the relative rotational movement with the shift guide groove 7 to cause interference. Do not occur.

When the selection operation is completed as described above, the electronic control unit drives the shift motor 23, and thus the shift lever 21 rotates.

Accordingly, the shift finger 19 of the shift lever 21 provides a force for the manual shaft holder 9 to linearly slide in the axial direction of the manual shaft 3 through the shift slider 29. At this time, the shift slider 29 allows a relative movement between the manual shaft holder 9 and the shift finger 19 of the shift lever 21 while sliding in the shift guide groove 7.

As described above, when the manual shaft holder 9 is linearly slid in the axial direction of the manual shaft 3, the manual shaft 3 itself fixed to the manual shaft holder 9 is also linearly slid. This is done so that the shift to the desired gear stage is completed.

In the present invention, as described above, the operation of rotating or linearly sliding the manual shaft 3 by the power of the motor is simply configured by only the worm gear, the link, and the sliding structure, thereby increasing the backlash due to the use of many gears. Excludes, improves power transmission efficiency, and allows simple product configuration at low cost.
