A four-wheel hydraulic braking system for a hilly and mountain tractor comprises a left front brake and a right front brake which are installed on the two sides of a gearbox respectively, a left rear brake and a right rear brake which are installed on the two sides of a rear axle respectively, and a braking oil tank and a braking pump which are used for supplying oil to the brakes. Brake pistons capable of pushing the friction plate assemblies to move are arranged in brake shells of the four brakes, a left brake pedal assembly and a right brake pedal assembly are arranged in a cab of the tractor, and movement of the left brake pedal assembly and the right brake pedal assembly can drive hydraulic oil to flow through a brake pump. The flow dividing valve and the reverse hydraulic lock are matched to adjust the flow direction of hydraulic oil, the reverse hydraulic lock can be opened in two directions when the left brake pedal and the right brake pedal move simultaneously, the hydraulic oil can flow into the four brakes simultaneously, four-wheel braking of the tractor is achieved, and the reverse hydraulic lock is kept closed when one of the left brake pedal and the right brake pedal moves independently. And hydraulic oil only flows into one brake positioned on the rear side, so that single-side rear wheel braking of the tractor is realized.

    一种用于丘陵山地拖拉机的四轮液压制动系统,包括分别安装在变速箱两侧的左前制动器和右前制动器、分别安装在后桥两侧的左后制动器和右后制动器、以及用于向制动器供油的制动油箱和制动泵,四个制动器的制动器壳体中设有能够推动摩擦片总成运动的制动活塞,拖拉机的驾驶室内设有左制动踏板总成和右制动踏板总成,左右制动踏板的运动能够通过制动泵驱动液压油的流动,并通过分流阀和反向液压锁配合调整液压油的流向,在左右制动踏板同时运动时反向液压锁会双向开启,液压油能够同时流入四个制动器,实现拖拉机的四轮制动,在左右制动踏板的单独一个运动时反向液压锁保持关闭,液压油只会流入一个位于后侧的制动器,实现拖拉机的单侧后轮制动。
