Abstract

A vehicle pedal resistance and kickdown assembly including a plunger moveable in a housing between first and second positions. The plunger defines a recess for a rod, A first spring in the housing biases the plunger in the first position. A second spring retains the rod in the plunger recess in the first position. In one embodiment, the recess in the plunger is an elongate recess in a flat front face of the plunger. In one embodiment, the housing defines an aperture in a to or bottom wall of the housing that has a length greater than the length of the second spring and the second spring is inserted lengthwise into the housing through the aperture. In one embodiment, the second spring is retained in a clip in the housing.

First claim

What is claimed is:

1. A vehicle pedal resistance and kickdown assembly comprising:
a case including a plurality of walls defining at least first and second interior cavities, one or more of the plurality of walls defining first and second apertures in communication with the first and second cavities respectively;
a first spring inserted into the first cavity through the first aperture in the one or more of the plurality of walls;
a plunger inserted into the first cavity through the first aperture in the one or more of the plurality of walls into a relationship abutting against one of the ends of the first spring and the plunger defining an external recess, the spring biasing a proximal end of the plunger outwardly from the case;
a rod inserted into the case through a third aperture defined in another of the walls of the case and into the recess defined in the plunger in a first position of the plunger;
a second spring inserted into the second cavity of the case through the second aperture in the one or more of the walls of the case into an abutting relationship against the rod and biasing the rod in the recess, the plunger being movable in the first cavity from the first position in which the rod is located in the recess to a second position in which the first and second springs are compressed and the rod is located outside the recess; and
a pair of clip arms unitary with the case and projecting outwardly from the second interior cavity of the case, the second spring being wedged between and in contact with the pair of clip arms.

2. A vehicle pedal resistance and kickdown assembly comprising:
a case including a plurality of was defining at least first and second interior cavities, one or more of the plurality of walls defining first and second apertures in communication with the first and second cavities respectively;
a first spring inserted endwise into the first cavity through the first aperture in the one or more of the plurality of walls;
a plunger inserted endwise into tie first cavity through the first aperture in the one or more of the plurality of walls into a relationship abutting against one of the ends of the first spring and the plunger defining an external recess, the spring biasing a proximal end of the plunger outwardly from the case;
a rod inserted endwise into the case through a third aperture defined in another of the walls of the case and into the recess defined in the plunger in a first position of the plunger; and
a second spring inserted lengthwise into the second cavity of the case through the second aperture in the one or more of the walls of the case into an abutting relationship against the rod and biasing the rod in the recess, the plunger being movable in the first cavity from the first position in which the rod is located in the recess to a second position in which the first and second springs are compressed and the rod is located outside the recess, the first and second apertures both being located in a first wall of the case, a clip being located in the second cavity of the case, the second spring being wedged in the clip and the clip including a pair of clip arms projecting outwardly from the interior surface of two of the plurality of walls of the case.
