Abstract
The disclosure relates to an assembly comprising parking brake and service brake pedal levers. The parking brake pedal lever engages and is maintained in a fixed location by a torsion spring. The torsion spring can be released by operating either the service brake or an accelerator.
Claims21
An assembly comprising:
- a parking brake pedal lever mounted upon a hub that defines an opening for receiving a shaft wherein said hub and lever are rotatably mounted on said shaft,
- a service brake pedal lever rotatably mounted on said shaft,
- an accelerator pedal lever and;
- a torsion spring mounted around said shaft wherein said torsion spring engages said shaft when the parking brake pedal is singularly operated and said torsion spring is disengaged by operating either said service brake pedal lever or said accelerator pedal lever.
1 more element
An assembly comprising:
- a service brake pedal lever,
- an accelerator pedal lever,
- a parking brake pedal lever that defines an opening for receiving a shaft wherein said lever is rotatably mounted on said shaft,
- a torsion spring mounted around said shaft that engages the shaft in response to movement of said parking brake pedal lever, and;
- a release lever that disengages said torsion spring upon operation of the service brake pedal lever or said accelerator pedal lever.
2 more elements
A pedal assembly comprising:
- a parking brake pedal lever mounted upon a first hub that defines an opening for receiving a shaft wherein said first hub and the parking brake lever are rotatably mounted on said shaft,
- a service brake pedal lever mounted upon a second hub that defines an opening for receiving said shaft wherein said second hub and the service brake lever are rotatably mounted on said shaft,
- a torsion spring mounted around said shaft that engages in response to movement of said parking brake pedal lever, and;
- a release lever mounted on said service brake pedal lever that disengages said torsion spring.
1 more element
An assembly comprising:
- a service brake pedal lever,
- an accelerator pedal lever,
- a parking brake pedal lever mounted upon a hub that defines an opening for receiving a shaft wherein said hub and said service brake pedal lever are rotatably mounted on said shaft,
- a torsion spring mounted around said shaft that engages the shaft in response to movement of said parking brake pedal lever,
- a means for disengaging said torsion spring, and;
- a brake cable that actuates braking system in response to movement of said parking brake pedal lever.
3 more elements
An assembly comprising:
- a parking brake pedal lever that defines an opening for receiving a shaft wherein said parking brake pedal lever is rotatably mounted on said shaft,
- a service brake pedal lever rotatably mounted on said shaft,
- an optional accelerator pedal lever and;
- a torsion spring mounted around said shaft comprising a first end that contacts the parking brake pedal lever and a second end that is positioned to contact a means for disengaging said torsion spring and wherein said torsion spring engages the shaft when the parking brake pedal is singularly operated and said means for disengaging functions by operating either said service brake pedal lever or said accelerator pedal lever.
1 more element
An assembly comprising:
- a parking brake pedal lever that defines an opening for receiving a shaft wherein said parking brake pedal lever is rotatably mounted on said shaft,
- a service brake pedal rotatably mounted on said shaft wherein the service brake pedal lever is biased into a position relative to the parking brake lever,
- an optional accelerator pedal lever;
- a torsion spring mounted around said shaft, and;
- a means for disengaging said torsion spring wherein movement of the service brake into an unbiased position or with the parking brake pedal lever causes operation of means for disengaging the torsion spring thereby preventing the torsion spring from engaging the shaft and permitting the parking brake pedal lever to rotate about the shaft with the service brake pedal lever, and wherein singular movement of parking brake pedal lever causes said torsion spring to engage the shaft thereby maintaining the parking brake pedal lever in a fixed location and the parking brake pedal lever is released from the fixed position by the means for disengaging which operates in response to movement of the service brake pedal lever or said optional accelerator pedal lever.
