The invention provides a work machine and a brake system. The braking system comprises a hand brake valve, a first trailer valve, a first differential valve and a parking air cylinder, the parking air cylinder is communicated with the first rear axle braking air chamber through the first differential valve, and the first air source input port is connected between the parking air cylinder and the first differential valve. And the first output port II is communicated with a first rear axle brake chamber through a control port of the first differential valve. According to the braking system provided by the invention, the first differential valve is arranged, so that air pressure can be established at the control port of the first differential valve whether a handle brake or a foot brake is stepped, and braking force is output for the first rear axle braking air chamber.
本发明提供一种作业机械及制动系统。制动系统包括手刹阀、第一挂车阀、第一差动阀和驻车储气筒,驻车储气筒通过第一差动阀与第一后桥制动气室连通,第一气源输入口连接在驻车储气筒和第一差动阀之间,第一Ⅱ输出口通过第一差动阀的一个控制口与第一后桥制动气室连通。本发明提供的制动系统,通过设置第一差动阀,无论是拉手刹或者踩脚刹,都可以在第一差动阀的控制口处建立气压,为第一后桥制动气室输出制动力。
