摘要： A brake system having a wheel brake and being operable under a non-failure normal braking mode and a manual push-through mode. The system includes a master cylinder operable by a brake pedal during the manual push-through mode to provide fluid flow at an output for actuating the wheel brake. A first source of pressurized fluid provides fluid pressure for actuating the wheel brake under the normal braking mode. A second source of pressurized fluid generates brake actuating pressure for actuating the wheel brake under the manual push-through mode.

摘要： The invention relates to an improved plunger assembly for a vehicle brake system. The plunger assembly is operable as a pressure source to control brake fluid pressure supplied to one or more wheel brakes. The plunger assembly comprises a housing defining a cylinder; a reversible motor supported by the housing and having a rotor; and a linear actuator such as a ball screw/nut mechanism driven by the motor. A plunger head is mounted in the cylinder and driven by the linear actuator in first and second opposite directions. Improvements include the plunger assembly engage at least one seal that defines a portion of a pressurized chamber. An end cap covers the projecting end of the cylinder and is secured to the housing to define a fluid passageway between the end of the cylinder and at least one fluid passageway provided in the housing block.

摘要： The invention relates to an improved plunger assembly for a vehicle brake system. The plunger assembly is operable as a pressure source to control brake fluid pressure supplied to one or more wheel brakes. The plunger assembly comprises a housing defining a cylinder; a reversible motor supported by the housing and having a rotor; and a linear actuator such as a ball screw/nut mechanism driven by the motor. A plunger head is mounted in the cylinder and driven by the linear actuator in first and second opposite directions. Improvements include, the cylinder projecting from one side of a housing with an end cap covering the projecting end of the cylinder and is secured to the housing block in a generally coaxial relationship with the cylinder. The cylinder and the end cap cooperate to define a fluid passageway between the end of the cylinder and at least one fluid passageway provided in the housing block. The plunger head may include a stop cushion assembly. The stop cushion assembly provides for a cushioned stop if the end of the piston head engages the fixed structure of the plunger assembly in the event of power loss.

摘要： A brake system includes first and second wheel brakes, a reservoir, and a brake pedal unit having a housing and a pair of output pistons slidably disposed in the housing. The output pistons generate brake actuating pressure during a manual push-through mode for actuating the first and second wheel brakes. The system further includes a plunger assembly having a housing having a motor driving an actuator, and a piston connected to the actuator. The piston pressurizes a chamber when the piston is moving in a first direction to provide fluid flow out of a first port and through a pair of parallel valves. The piston pressurizes a second chamber when the piston is moving in a second direction opposite the first direction to provide fluid flow out of a second port. The first and second ports are selectively in fluid communication with the wheel brakes.
