摘要： A disc brake caliper assembly has a housing with a bore. A piston in the bore is movable between applied, retracted and knock-back positions. The piston is activatable by hydraulic pressure to move from the retracted position to the applied position; and a retracting seal is effective in the absence of the hydraulic pressure to move the piston from the applied position to the retracted position. A linkage adjacent the piston carries a stop; and an actuator is responsive to an end of brake activation signal to cause the linkage to engage the stop with the piston when the piston is retracted from its applied position to its retracted position so as to prevent the piston from moving from the retracted position to the knock-back position. The actuator is preferably a comparatively weak electric motor that stalls as the stop engages the piston; and the stall is sensed to end motor activation. The end of brake activation signal is preferably provided by a brake position or pressure sensor. The apparatus is adaptable to an electronic park brake control.

摘要： A drum brake assembly for a vehicle is provided. A backing plate supports opposing brake shoes with a drum disposed there about. Each of the brake shoes has a portion in spaced relation from one another. A wheel cylinder is supported by the backing plate and is arranged between the portions of the brake shoes for forcing the portions away from one another to engage the brake shoes with the drum in a brake position. A strut interconnects the brake shoes proximate to the portions. A lever has a first end, which extends to a second end, supported from one of the portions by a pivotal connection. The lever is rotatable about the pivotal connection between a normal operating position in which the strut is spaced from the lever and a parking brake position in which the lever engages the strut to maintain the portions in the brake position. An electric parking brake actuator is supported by the backing plate and includes a linkage that coacts with the second end of the parking brake lever. The linkage is actuatable by the electric parking brake actuator for moving the lever between the normal operating and the park brake positions. The electric parking brake actuator moves the lever to the parking brake position in response to a parking brake signal with the brake shoes in the brake position.

摘要： A disc brake caliper assembly is provided that includes a housing having a bore. A piston is arranged within the bore and is movable between normal retracted and knock-back positions. A linkage is adjacent to the piston and is movable between first and second positions with a clearance between the piston and the linkage in the first position. The clearance undesirably permits the piston to move to the knock-back position during severe operating conditions. An actuator, which also may be used as part an electric parking brake, moves the linkage from the first position to the second position to eliminate the clearance when the linkage is moved from the first position to the second position where the linkage abuts the piston. The linkage is connected to the caliper housing by a support. The linkage prevents the piston from moving from the normal retracted position to the knock-back position. In operation, the present invention prevents piston knock-back by sending an adjustment signal from a controller to the actuator at a predetermined interval. The signal commands the actuator to move a linkage from the first to the second position where the linkage abuts the piston. In this manner, the linkage prevents the piston from moving from a normal retracted position to a knock-back position.

摘要： A brake by wire system provides the capability of both travel and force sensors on a brake apply input member such as a brake pedal and also provides redundancy in sensors by providing the signal from a sensor responsive to travel or position of the brake pedal to a first controller and the signal from a sensor responsive to force applied to the brake pedal to a second controller. The first and second controllers are connected by a bi-directional communication link whereby each controller may communicate its received one of the sensor signals to the other controller. In at least one of the controllers, linearized versions of the signals are combined for the generation of first and second brake apply command signals for communication to brake apply units. If either controller does not receive one of the sensor signals from the other, it nevertheless generates its brake apply command signal on the basis of the sensor signal provided directly to it from the sensor. In a preferred embodiment of the system, a controller combines the linearized signals by choosing the largest in magnitude.

摘要： A vehicle braking system that primarily operates as a pure brake-by-wire system, with optional hydraulic actuation. The system includes a set of four electrically actuated drum brakes. At least two of the wheel brakes include hydraulic actuators that operate to apply the wheel brakes independent of electric control. Each of the wheel brakes is normally operated in response to a control signal generated by the vehicle's brake processor. As such, a primary brake-by-wire system is provided at all four vehicle wheels. The rear brakes are proportioned to the front brakes electrically, according to design criteria.

摘要： A brake system includes a pedal feel emulator and a master cylinder with a damping mechanism having a damping piston. When the emulator piston is moved from the at-rest position, fluid is displaced from the emulator through a compensation port and through a flow restrictive orifice in the damping piston to the reservoir. Flow rate of the fluid is dependent on the apply rate of the brake pedal. When the brake pedal is applied relatively slowly, sufficient flow volume will occur through the flow restrictive orifice and the damping piston will remain unmoved. As apply rates increase, a sufficient pressure differential will eventually be established across the damping piston to cause it to move. Damping piston movement compensates for rapid fluid displacement out of the variable chamber and enables a desirable pedal feel characteristic where pedal force increases relatively slowly as pedal velocity increases relatively rapidly. As the damping piston movement provides increasing volume, the pressure differential drops across the damping piston and it will cease to move as flow is accommodated solely through the flow restrictive orifice. As this occurs, pedal force will increase more rapidly providing a two-stage damping characteristic.
摘要翻译：制动系统包括踏板感觉模拟器和具有阻尼机构的主缸，该阻尼机构具有阻尼活塞。当仿真器活塞从静止位置移动时，流体从仿真器通过补偿端口并通过阻尼活塞中的限流孔移动到储存器。流体的流速取决于制动踏板的施加率。当制动踏板相对缓慢地施加时，通过限流孔会发生足够的流量，并且阻尼活塞将保持不动。当施加率增加时，将最终在阻尼活塞上建立足够的压力差，以使其移动。阻尼活塞运动补偿了可变腔室中的快速液体位移，并且能够提供令人满意的踏板感觉特性，其中踏板力相对较慢地增加，因为踏板速度相对快速地增加。随着阻尼活塞的运动提供增加的体积，压力差通过阻尼活塞而下降，并且当流仅容纳通过限流孔口时，其将停止移动。当发生这种情况时，踏板力将增加更快，提供两级阻尼特性。
