Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a change control device for an automobile with a devised select return spring mechanism.

(Prior Art) Conventionally, as shown in FIG. 4, as a change control device for an automobile, a ball seat cover 3 is attached to a bracket 2 on a base plate 1, and a change lever is controlled by a ball seat inside the ball seat cover 3. The ball part 4 is supported so as to be swingable in the shift direction and the select direction,
There is one in which the select lever 5 is swung in the select direction by the select operation of the change lever 4, and the interlocking pin 6 is swung in the shift direction by the shift operation of the change lever 4.

By the way, as a select return spring mechanism for returning the change lever 4 to the neutral position in the select direction, as shown in FIG. A select return spring 9 is stretched between one end of each lever 7, 8, and the other end, into which a rubber 10, 11 is fitted, is connected between the fork portion 5a of the select lever 5 and the long groove 1a of the base plate 1. When the select lever 5 is swung in the select direction by the select operation of the change lever 4, the other end of one of the levers 7, 8 comes into contact with one edge of the long groove 1a, and the select lever 5 The fork part 5a of the other lever 8,
When the other end of the select return spring 9 is pushed, the select return spring 9 is stored, and when the change lever 4 is released, the change lever 4 is returned to the neutral position by the stored force of the select return spring 9. .

However, such a select return spring mechanism provided at the select lever fulcrum has problems in that it requires a large number of parts and is difficult to assemble.

(Purpose of the invention) The present invention was made to solve the above-mentioned conventional problems, and by providing a simple select return spring mechanism at the change lever fulcrum, it reduces the number of parts and improves ease of assembly. The purpose is to

(Structure of the invention) Therefore, in the present invention, the fulcrum of the change lever is configured such that semicircular drums disposed on both sides in the selection direction are pivoted by pins so as to be relatively rotatable in the shift direction. The drum at the fulcrum is supported by a drum seat inside the drum seat cover so as to be able to swing freely in the select direction, and the side surface of the drum seat cover has an arc shape extending symmetrically from the neutral position of the change lever in the select direction. A long hole is formed on the side of the drum at the fulcrum of the change lever, and a long groove of the same shape as the long hole is formed on the side of the drum at the fulcrum of the change lever. A select return spring is provided, and both ends of the select return spring are inserted through the long holes of the drum seat cover and respectively locked in the long grooves of the drum. be.

(Effect of the invention) According to the invention, both ends of the select return spring are inserted through the long holes on the side of the drum seat cover, and are engaged with the long grooves of the drum at the fulcrum part of the change lever, so that the select return spring can be used to control the change. Since the lever is designed to return to the neutral position, there is no need for an X-shaped lever or rubber, which reduces the number of parts and greatly improves ease of assembly.

(Example) As shown in FIGS. 1 and 3, the drum seat cover 15 attached to the bracket on the base plate is formed into a square tube shape, and inside the drum seat cover 15 is a semicircular shape in the selection direction. Upper and lower drum sheets 16 and 17 having respective recesses 16a and 17a are fitted therein.

The fulcrum part 19 of the change lever 18 is constructed by semicircular drums 20, 20 pivoted on both sides in the select direction by pins 21, 21 so as to be relatively rotatable in the shift direction. 20,
20 is the concave portion 16 of the drum sheets 16, 17
a, 17a.

Therefore, when the change lever 18 is operated to select, the change lever 18 is moved to the drum seat 1.
When the change lever 18 is swung in the select direction by the drums 20 and 20 that fit into the recesses 16a and 17a of the drums 6 and 17, and the change lever 18 is shifted, the change lever 18 is moved by the pins 21 and 20 that fit into the drums 20 and 20, respectively. 21 so that it can be swung in the shift direction.

On the other hand, as also shown in FIG. 2a, on one side 15a of the drum seat cover 15 in the shift direction, a swinging fulcrum P of the change lever 18 is passed through with respect to the change lever 18 in the neutral (vertical) position. Arc-shaped long holes 15b and 15c are formed that extend symmetrically in the selection direction with the horizontal line L in between.

Further, long holes 16b, 17b of the same shape are formed on the side surfaces of the upper and lower drum seats 16, 17, and long grooves 20a, 20b of the same shape are formed on the side surface of the drum 20 of the fulcrum portion 19 of the change lever 18. .

A stopper plate 22 is erected outside the drum seat cover 15 facing the side surface 15a, and a pin 23 is implanted in the stopper plate 22 coaxially with the swinging fulcrum P of the change lever 18. , the select return spring 2 is attached to the pin 23.
4 is wrapped.

The select return spring 24 has both ends 24a and 24b biased in the cross direction, and each end 24a and 24b is connected to the drum seat cover 15.
Insert through the long holes 15, 15c of the side surface 15a and the long holes 16b, 17b of the upper and lower drum seats 16, 17,
They are respectively engaged with the inner edges of the long grooves 20a and 20b of the drum 20.

With the above configuration, as shown in FIG. 2a, when the change lever 18 is released, both ends 2 of the select return spring 24
4a, 24b are pressed against the inner edges of the elongated holes 15b, 15c of the side surface 15a while being biased in the cross direction, so that the elongated grooves 20a, 20 of the drum 20
0b is aligned with the elongated holes 15b and 15c, and the change lever 18 has returned to the neutral position.

Then, as shown in Figure 2b, change lever 1
8 to the right side, the end 24a of the select return spring 24 is locked at the inner edge of the long groove 20a of the drum 20, so the rotation of the drum 20 causes the long hole 15b of the side surface 15a to open.
is moved upward and energy is stored.

Therefore, when you release your hand from the change lever 18,
With this accumulated force, the end 24 of the return spring 24
a rotates the drum 20 in the reverse direction, and the change lever 1
8 to return to the neutral position.

Note that when the change lever 18 is selectively operated to the left, the change lever 18 is returned to the neutral position in the same manner.
