Description

[Detailed Description of the Invention] The present invention relates to an automatic transmission gear shift operation moderation device that improves the sense of moderation during gear shift operation.

A vertical cross section of a conventional automatic transmission transmission moderation device is shown in FIG. 1, and another example of the ball pressing type is shown in FIG.
Another example of a separate lever pull type is shown in FIG.

In FIG. 1, reference numeral 1 designates the housing of the operating lever, and when the operating button 2 is pressed, the operating rod 3 is pushed down by the cam 9 while compressing the rod return spring 7a. At the same time, the above operating rod 3
The pin 12 fixed to the lower end of the detent plate 10 is released from meshing with the toothed part formed on the upper side of the hole of the detent plate 10. However, the roller pin 11 and the upper notch 13 formed on the upper part of the detent plate 10 are engaged with each other with a sense of moderation by the spring 7b for pressing the pin 11.

In order to set the sense of moderation, use the roller pin 1 mentioned above.
1 and the upper notch 13 are a ball pressing method as shown in FIG. 2 and a different method as shown in FIG. It has a lever pull type. In any of these cases, the sense of moderation was set only by pressing the roller pin 11 against the upper notch 13 with the spring 7c.

By the way, in the above-mentioned conventional moderation device, the spring 7b or 7c for setting the moderation feeling and the operation button are not included.
Since the return spring 7a of the detent plate 10 is a separate part, the cost is high.
Since it is determined only by the shape of the button, there is a limit to how the sense of moderation can be changed at a predetermined operating position.

The present invention has been developed in view of the drawbacks of the conventional devices mentioned above.
It is an object of the present invention to provide an automatic transmission gear change operation moderation device that can improve moderation feeling with a simple configuration.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 4 is a longitudinal sectional view of the device of the present invention, and Fig. 5 is a longitudinal sectional view of the device of the present invention.
Fig. 6 is a partial sectional view of the operating rod taken in the direction of the arrow in the figure; Fig. 6 is a partial sectional view of the guide taken in the same direction;
The figure is a partial cross-sectional view taken in the same direction showing a state in which the operating rod and guide are combined.

a button 2 slidably provided within the housing 1;
By pressing this button 2, the operating rod 3 is pushed down via the cam 9. Operation rod 3
A guide 5 is slidably provided between the lever 4 and the lever 4, and a spring seat 14 is formed at the end of the guide 5, and a spring for returning the only operating rod 3 is provided between the lower end of the operating rod 3 and the lower end of the operating rod 3. 7a is loaded.

A plate-shaped detent plate 10 is provided on the outside of the lever 4, and the upper surface thereof has an appropriate number of upper notches each having the same shape as the upper notch 13 shown in FIG. is formed,
A hole is provided below the hole, and an appropriate number of lower notches 15 (FIG. 7) are formed on the upper side of the hole, each notch having a different shape. That is, the lower notches 15 are formed so that the distances between the lower notches 15 and the locus of rotation of any part of the lever 4 are unequal.

Therefore, the pin 12 is fixed to the lower end of the operating rod 3 and is slidably provided in the long groove of the guide 5 (Figs. 6 and 7) and the hole in the detent plate 10. The force engages one of the irregularly shaped lower notches 15 in the hole of the detent plate 10.

The roller pin 11 is fixed to the guide 5 (Fig. 6), and the long groove of the operating rod 3 (Fig. 4, 5)
) and the long groove of the lever 4 (FIGS. 4 and 7), and its roller pin 11 is engaged with the upper notch 13 by the negative force of the spring 7a.

Therefore, when the operating rod 3 is pressed down by the button 2, the spring 7a is compressed downward, and at the same time, the guide 5, on which the spring seat 14 is formed at the lower end, is further pushed by the operating rod due to the negative force of the spring 7a. The roller pin 11 fixed to the guide 5 presses the upper notch 13 more strongly due to the negative force of the spring 7a.
2 disengages from the lower notch 15.

That is, the spring 7a serves both as a spring for returning the operating rod 3 for engaging and disengaging the pin 12 and as a spring for pressing the moderation improving roller pin 11.

Now, when the button 2 slidably provided in the housing 1 is pressed, the operating rod 3 is activated via the cam 9.
is pushed down while compressing the spring 7a in the guide 5, and the engagement between the pin 12 attached to the operating rod 3 and the lower notch 15 formed in the hole of the detent plate 10 is released, and each range is opened. In addition to enabling speed change operation, the roller pin 11
is strongly pressed against the upper notch 13, so that the sense of moderation is strengthened during gear shifting operations. That is,
An appropriate number of upper notches 13 of the same shape for moderation are formed on the upper surface of the detent plate 10 and roller pins 11 attached to the guide 5 are engaged,
By increasing the pressing force of the spring 7a during a speed change operation, the sense of moderation during a speed change operation can be strengthened.

Note that the pin 12 is negatively biased by the spring 7a so as to press against the lower notch 15, and each notch of the lower notch 15 due to the negative force is formed into an uneven shape with a step difference, so that the button 2
In the engaged state in which the operating rod 3 is not operated and the operating rod 3 is not pushed down, the pressing force can be strengthened, and different holding forces of the shift lever can be obtained in each range.

According to the moderation device of the present invention, since the operating rod return spring and the pressure spring for moderation improvement are used together, the number of parts is reduced, the number of assembly steps is also reduced, and the cost is reduced.

Furthermore, compared to the conventional device shown in FIG. 1, the inner diameter machining portion of the lever can be shortened, making machining easier.

Further, since the roller pin pressing force increases or decreases in proportion to the button pressing stroke amount, the sense of moderation at a predetermined operating position can be easily changed by setting the upper notch of the detent plate.
