A select arm which rotates about the pivot center axis in association with a right horizontal movement; It is characterized by consisting of.

EXAMPLE

Hereinafter with reference to the accompanying drawings an embodiment of the present invention will be described in detail.

1 is a front view showing an embodiment of the shift lever assembly of the present invention,

2 is a side view of the in-phase device,

3 is a detailed plan view of the select arm,

4 is a diagram illustrating a shift state according to a shift lever position.

In the figure, reference numeral 1 denotes a lower bracket, and the lower bracket 1 is fixed to the bottom of the vehicle body through its base 2.

The lower bracket 1 is fixed by fastening the upper bracket 3 and the bolts 4, and a spherical groove 5 is formed between the upper and lower brackets 3 and 1.

The spherical groove 7 is accommodated in the spherical ball 7 of the shift lever 6 and the spherical ball 7 is allowed to move in the spherical groove 5.

The shift lever 6 protrudes upward through the opening 8 of the upper bracket 3, and the opening 8 is a vertical direction for shifting the gear of the shift lever 6 (front and rear of the vehicle). Direction) It is open enough to allow movement in the horizontal direction (vehicle left and right) for the gear select.

The shift shaft 10 is fixed to the spherical ball 7 through the opening 9 on one side of the upper and lower brackets 3 and 1, and extends and protrudes horizontally. To the end portion 10 ', the shift arm 11, which is vertically downward again, is fixed to form an L shape.

The gear shift cable 12 is connected to the end 11 'of the shift arm 11, and when the shift lever 6 is rotated from the neutral position A to the front position B, the end of the shift arm 6 11 'is rotated rearward (refer to the dashed-line figure), and with the gear select operation described later, the transmission gear state can be selected from one, three, or five gears.

On the other hand, when the shift lever 6 rotates the spherical ball 7 to the rear position C from the center point, the end 11 'of the shift arm 11 pivots forward (see the dashed-dotted line) and the shift cable 12 Through the transmission gear state of the transmission gear is to select one of the second, fourth, or reverse (R).

The lower bracket 1 has an open portion 13 open toward the bottom of the vehicle body, and the select shaft 14 fixed to the lower portion of the spherical ball 7 is vertically downward through the open portion 13. The free end 14 'of the select shaft 14 protrudes and is fitted into a hole formed in one end body 16 of the select arm 15, preferably a long hole 17.

One end body 16 and the long hole 17 of the select arm 15 extend elongated along the front and rear longitudinal directions of the vehicle, and the select shaft 14 when the shift lever 6 is shifted. ) Moves back and forth along the guide of the long hole 17.

The select arm 15 has a pivot center 18 spaced apart from the select shaft 14 and rotates about a bolt shaft 19 fixed perpendicular to the base 2 in the embodiment of the present invention. .

The gear select cable 21 is connected to the end of the main body 20 of the select arm 15, and the main body 20 extends at right angles to the longitudinal direction of the long hole 17. In addition, the one end body 16 is integrally formed with the vertical member 22 extending vertically from the main body and the main body 20. A return spring 23 is fitted to the bolt shaft 19 and the main body 20 of the select arm 15 is fitted to the bolt shaft 19 so as to be supported by the return spring 23.

Both sides of the main body 20 of the select arm 15 are supported by the support parts 24 and 24 'protruding from the return spring 23, and a part of the coil body of the return spring 23 is the base 2 or Since it is fixed to the bolt shaft 19, when the main body 20 is rotated, the support portions 24 and 24 'positioned on the rotating side are deformed and elastic restoring force is accumulated in the return spring 23, and this elastic restoring force Acts as a return force when the shift lever 6 returns to the neutral position.

Accordingly, when the shift lever 6 is in the neutral position D, the select shaft 14 is in a vertically downward state, and when the shift lever 6 is rotated to the left position E in the horizontal direction, the select shaft ( 14 rotates in the opposite direction.

When the select shaft 14 moves, the select arm 15 constrained by its free end 14 'rotates clockwise around the bolt shaft 19 (see dashed line). As the shift lever 6 is located at the A and E points, the shift lever 6 can be shifted, that is, the gear 1 or the gear 2 can be selected according to the shift, that is, the pulling operation in the front and rear directions of the vehicle. will be.

If the shift lever 6 is pushed forward, the front end of the shift arm 11 rotates rearward to pull the gear shift cable 12 to perform a shift, and the shift lever 6 is located in the B · E position. (See the dashed-dotted state of the select and shift arms), the transmission is in one stage.

When the clutch is pressed again and the shift lever 6 is pulled backward and positioned at C · F, the shift arm 11 and the select arm 15 are in the two-shift position as shown, and the gear of the transmission is in the two-shift state. To be.

The selection of the 3rd stage (B, A), 4th stage (C, D), 5th stage (B, F) and reversing (C, F) operates according to the same principle depending on the rotational position of the shifting lever (6). Detailed description thereof will be omitted.

On the other hand, if the gear shifts to the A, E or A, F position by slightly touching the shift lever 6 to return to the neutral position (A, D) from the 1st, 2nd, or 5th stage, and the reverse shifting state (Fig. 2A lever position) ) The select arm 15 returns to the normal state by the elastic restoring force accumulated in the return spring 23. Accordingly, the select shaft 14 and the shift lever 6 also rotate to rotate the neutral position (A · D) position, FIG. 1 automatically returns to the D lever position.

[effect]

According to the present invention as described above, the spherical ball of the shift lever is accommodated in the spherical groove of the upper and lower brackets, the movement of the front and rear, left and right of the shift lever is allowed, and the spherical ball is respectively with the spherical ball on the side and the bottom Rotating shift arm and select arm are provided, so the structure is very simple and the number of parts is short, so that assembly time can be shortened, vehicle price can be lowered, and maintenance and maintenance are easy.
