Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to an improvement in an overstroke absorption mechanism for an accelerator pedal, which operates a kick-down switch in response to an overstroke of the accelerator pedal.

[Conventional technology]

An overstroke absorption mechanism is required to allow the accelerator pedal to overstroke in order to turn on the kick-down switch for kicking down the automatic transmission of a car when the accelerator pedal is further depressed from full throttle. Is required. As one such overstroke absorption mechanism, for example, as disclosed in Japanese Utility Model Application No. 59-182731, there is a shaft located near the tip of the rod of the accelerator pedal, centered at a shaft perpendicular to the swinging surface of the rod. an accelerator cable mounting bracket supported swingably as At a position far from the pedal, there is an overstroke absorption mechanism for the accelerator pedal, which includes a cable attachment part that supports the end of the accelerator cable, and a stopper that abuts against the tip of the rod in the direction in which the accelerator cable is pulled. . This is called a center-folding overstroke absorption mechanism.

[Problem that the invention attempts to solve]

In the above-mentioned center-folding type overstroke absorption mechanism, the accelerator cable mounting bracket is pressed against the rod of the accelerator pedal by a spring, and the depression displacement of the accelerator pedal changes from the rod to the accelerator cable mounting bracket. Because it has become transmitted, if
When the spring in the overstroke absorption mechanism is damaged, the accelerator cable mounting bracket is pulled by the return spring of the accelerator cable and rotates around the shaft in the direction in which the accelerator cable returns. There is a problem in that even if you press the pedal to the maximum, you will not be able to pull the accelerator cable. In this way, if the accelerator cable cannot be pulled, the car will suddenly decelerate and the engine will be in an idling state, making it impossible to drive the car.

[Purpose of invention]

This invention was made in view of the above-mentioned conventional problems, and even if the spring that biases the accelerator cable mounting bracket in the direction of pulling the accelerator cable is damaged, the accelerator cable can be pulled. An object of the present invention is to provide an overstroke absorption mechanism for an accelerator pedal that can increase rotation.

[Means to solve the problem]

This invention consists of an accelerator cable mounting bracket that is supported near the tip of an accelerator pedal rod so as to be able to swing around a shaft that is orthogonal to the swinging surface of the rod, and an accelerator cable mounting bracket that is supported in the direction in which the accelerator cable is pulled. a spring biasing the accelerator cable, and the accelerator cable mounting bracket includes a cable mounting portion that supports an end of the accelerator cable at a position remote from the accelerator pedal with respect to the shaft, and a distal end of the rod. On the other hand, in an accelerator pedal overstroke absorption mechanism that includes a stopper that abuts in the direction in which the accelerator cable is pulled, the accelerator cable mounting bracket is prevented from swinging by more than a certain angle about the shaft in the direction of returning the accelerator cable to the accelerator cable. The above object is achieved by providing a second stopper that restricts the movement.

[Effect]

In this invention, even if the spring that biases the accelerator cable mounting bracket in the direction of pulling the accelerator cable is damaged and the accelerator cable mounting bracket swings in the direction of returning the accelerator cable, the second stopper keeps the accelerator cable mounting bracket at a constant position. In order to restrict swinging beyond an angle, the accelerator cable can be pulled by the accelerator pedal, and a sudden drop in engine speed can be prevented.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. In this embodiment, as shown in FIG. 1, a shaft 14 is provided near the tip of the rod 12 of the accelerator pedal 10, which is perpendicular to the swinging surface 12A of the rod 12.
The accelerator cable mounting bracket 16 is supported swingably around the accelerator cable 18.
a spring 20 biasing in the tensile direction;
The accelerator cable 1 is attached to the cable attachment part 22 that supports the
8. In the accelerator pedal overstroke absorption mechanism comprising a stopper 24 that abuts in the tension direction, the accelerator cable mounting bracket 16 is placed at a position on the side closer to the accelerator pedal 10 with respect to the shaft 14. 16 comes into contact with the rod 12 when it swings at a certain angle or more about the shaft 14 in the direction in which the accelerator cable 18 is returned.
A second stopper 26 is provided to restrict the swinging. Reference numeral 28 in the figure is a kick-down switch that is turned on by the rod 12 when the accelerator pedal 10 is further overstroked from the full throttle, and 30 is a rocking shaft that swingably supports the intermediate position of the rod 12. Reference numeral 32 indicates a return spring for the rod 12, which is attached to the position of this swing shaft 30. Here, the shaft 14 swingably supports an accelerator cable mounting bracket 16, and is welded to the rod 12 at an end projecting from the accelerator cable mounting bracket 16. The stopper 24 is a recess formed in the accelerator cable mounting bracket 16, and
The bent end portion 12B of the second end enters the stopper 24, which is the recessed portion, and is engaged with the accelerator cable mounting bracket 16. The spring 20 is mounted on a portion of the shaft 14 that passes through the accelerator cable mounting bracket 16, and one end thereof is engaged with a locking hole 16B formed in the accelerator cable mounting bracket 16, and the other end is engaged with the rod 12. The accelerator cable mounting bracket 16 and rod 12 are connected to the bent end portion 12.
Both are urged so that they come into pressure contact at position B. The second stopper 26 is a member bent and extended from the end of the accelerator cable mounting bracket 16 opposite to the cable mounting portion 22, and
In a steady state, that is, when the bent end portion 12B of the rod 12 is in pressure contact with the stopper 24 of the accelerator cable mounting bracket 16 by the spring 20, it is spaced a certain distance from the rod 12 (see Fig. 3) and , accelerator cable mounting bracket 16
is formed so that when it swings clockwise at a certain angle about the shaft 14 in FIG. 3, its tip comes into contact with the rod 12 (see FIG. 4). Next, the operation of the above embodiment will be explained. In a normal state, that is, when the spring 20 is not damaged, the bent end portion 12B of the rod 12 is moved by the spring 20 to the stopper 2 when the accelerator pedal 10 is pressed down to the full throttle position.
4 is maintained in pressure contact. When the accelerator pedal 10 is pressed further from the full throttle to overstroke, the rod 12 is slightly separated from the accelerator cable mounting bracket 16 against the biasing force of the spring 20, allowing the overstroke and preventing kickdown. Allow switch 28 to be turned on. Here, if the rod 12 is used as a reference, the accelerator cable mounting bracket 16 will be swung clockwise in FIG. is small and smaller than the stroke of the second stopper 26 in contact with the rod 12.
The switch 28 does not come in contact with the switch 28 and prevent the switch 28 from turning on. If the spring 20 breaks while the vehicle is running, the accelerator cable mounting bracket 16 will be pulled by the accelerator cable 18 and will swing clockwise about the shaft 14 from the position shown by the two-dot chain line in FIG. be moved. When the accelerator cable mounting bracket 16 is swung clockwise, the second stripper 26 formed at its end comes into contact with the rod 12.
The accelerator cable mounting bracket 16 is prevented from further swinging clockwise from the state shown by the solid line in FIG. Therefore, the accelerator cable mounting bracket 16
However, in the range from the position indicated by the two-dot chain line to the position indicated by the solid line in FIG. By inserting the accelerator cable 18 into the accelerator cable mounting bracket 16
It can be pulled through. Therefore, a rapid decrease in engine speed can be avoided. In this embodiment, since it can be constructed by simply adding the second stopper 26 to the conventional accelerator cable mounting bracket, the manufacturing cost is low and it has the advantage that it can be easily applied to the conventional overstroke absorption mechanism. be. In the above embodiment, the second stopper 26 is attached to the accelerator cable mounting bracket 16.
Although the second stopper 26 is formed closer to the accelerator pedal 10 than the shaft 14, the present invention is not limited to this.
Any material may be used as long as it can restrict the swinging of the accelerator cable mounting bracket 16 in the accelerator cable return direction by a certain angle or more about the shaft 14. Therefore, for example, the second stopper may be provided at a position farther from the accelerator pedal 10 than the shaft 14 in the accelerator cable mounting bracket 16, and may also be provided on the rod 12 side.

[Effect of the idea]

Since the present invention is constructed as described above, the rocking of the accelerator cable mounting bracket in the direction of the return of the accelerator cable by more than a certain angle due to breakage of the spring while the car is running is restricted, thereby preventing a rapid decrease in engine speed. It has the excellent effect of being able to
