Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an accelerator linkage device for a vehicle,
In particular, the present invention relates to an accelerator linkage device for a vehicle that links an accelerator pedal and an output control lever of a vehicle drive source.

The accelerator pedal of the vehicle is linked to the output control lever of the vehicle drive source via a connecting rod,
By depressing the accelerator pedal, the output control lever of the vehicle drive source is rotated to accelerate the vehicle.
In conventional vehicle accelerator link devices, the attachment position of the connecting rod to the accelerator pedal is located below the pivot point of the accelerator pedal on the vehicle body. Therefore, in order to increase the rotational stroke of the accelerator lever, it is necessary to pivot one end of the connecting rod onto the accelerator pedal as far as possible below the pivot point of the accelerator pedal in the vehicle body. On the other hand, from the viewpoint of getting on and off the vehicle, it is necessary to make the floor of the vehicle as low as possible.
However, if the floor of the vehicle is lowered and the attachment point of the connecting rod on the accelerator pedal is positioned far below the rotational fulcrum of the accelerator pedal, the attachment point of the connecting rod on the accelerator pedal will be lowered from the bottom of the vehicle. As a result, while the vehicle is running, obstacles on the road may come into contact with the lower end of the accelerator pedal, connecting rod, etc. and damage it, resulting in unnecessary vehicle running and wire harness burnout. There is a risk of accidents etc.

The present invention has been made in order to eliminate the drawbacks of the conventional accelerator linkage device for vehicles, and it allows the rotation stroke of the accelerator lever of the vehicle to be made large, and the attachment part of the connecting rod in the accelerator pedal is fixed to the vehicle. To provide an accelerator link device for a vehicle that does not protrude downward from the bottom surface. The present invention provides an accelerator pedal that is pivotally supported on a vehicle body and biased by an elastic member in a direction opposite to the direction of rotation when the pedal is depressed, and an upper end that is swingable above the pivot point relative to the accelerator pedal. It has a supported swinging arm, and a connecting rod having one end connected to the pivot point of the accelerator pedal on the lower end side of the swinging arm and the other end connected to an output operating member of the vehicle drive source. It is characterized by

With the above configuration, the attachment position of the connecting rod can be moved closer to the pivot point of the accelerator pedal while maintaining a large stroke amount of the connecting rod.
While lowering the height of the vehicle floor surface, there is no risk of contact with road obstacles.
