Abstract
The present disclosure relates to various vehicle braking assemblies. Brake pedal arms include, for example, a cam block that is configured to simplify the engagement between the power booster and pedal arm. Cam block can be movable with respect to the pedal arm to manage the gap between the pedal arm and power booster in by-wire braking assemblies.
Claims5
A brake pedal assembly for a vehicle having a regenerative braking system and a hydraulic braking system, the assembly comprising:
- a booster assembled to the vehicle and operatively connected to the hydraulic braking system;
- a pedal arm including a cam surface, wherein the pedal arm and cam surface define an opening, and wherein the pedal arm moves from an unapplied position through a first arc of rotation and a second arc of rotation to an applied position;
- a push rod for actuating the booster, wherein the push rod extends from the booster to the pedal arm and is received in the opening defined by the pedal arm and the cam surface;
- a flange attached to the push rod at a spaced location relative to the cam surface when the pedal arm is unapplied and through the first arc of rotation, and wherein the flange is engaged by the cam surface to actuate the booster in the second arc of rotation, wherein the regenerative braking system is actuated when the pedal arm is moved in the first arc of rotation and the hydraulic braking system is actuated only when the pedal arm is moved in the second arc of rotation.
