  • Pedal brake electric boost for advanced vehicle platforms
    Patent number: 11851037
    Abstract: A pedal brake assembly comprises a master cylinder block defining a bore extending along a center axis. At least one brake piston is slidably disposed in the bore. A push rod, having a body portion and an end portion, extends between a first end and a second end. The second end is coupled to a brake pedal. A housing defines a channel for receiving the push rod. An actuator couples to the at least one brake piston. The body portion is slidably disposed in the channel. The end portion is in an abutment relationship with the housing and defines a hole extending from the first end to the body portion. A plunger is slidably disposed in the end portion for engaging the at least one brake piston whereby the push rod and the actuator are independently movable along the center axis.
