The invention relates to a brake system with front brake source selection. A brake system includes a reservoir and a master cylinder operable to provide a brake signal in response to actuation of a brake pedal connected to the master cylinder. The power transmission unit is configured to selectively provide pressurized hydraulic fluid for actuating at least one of the pair of front wheel brakes and the pair of rear wheel brakes in a normal failless braking mode. A plurality of isolation/relief valve devices are each hydraulically interposed between the power transmission unit and a corresponding one of the wheel brakes. The plurality of two-position three-way valves are each hydraulically connected with the master cylinder, the power transmission unit and at least one selected wheel brake of the pair of front wheel brakes. A two-position three-way valve selectively controls hydraulic fluid flow from a selected one of the master cylinder and the power transmission unit to a corresponding one of the front wheel brakes.
本发明涉及具有前制动源选择的制动系统。一种制动系统包括储存器和主缸,该主缸能操作成响应于连接到所述主缸的制动踏板的致动而提供制动信号。动力传输单元构造成在正常无故障制动模式下选择性地提供用于致动一对前轮制动器和一对后轮制动器中的至少一个的加压液压流体。多个隔离/卸压阀装置均液压地介于动力传输单元与车轮制动器中对应的一个之间。多个二位三通阀均与主缸、动力传输单元和一对前轮制动器中的至少一个选定的车轮制动器液压连接。二位三通阀选择性地控制从所述主缸和所述动力传输单元中选定的一个到所述前轮制动器中对应的一个的液压流体流。
