The all-terrain vehicle braking system comprises a front wheel braking assembly, a rear wheel braking assembly, a braking pedal, a hand brake pump and a hydraulic pump, the hydraulic pump comprises a pump body, a piston mechanism, a connecting rod mechanism and an elastic mechanism, the pump body is provided with a hand brake oil inlet, a first oil outlet, a second oil outlet and a liquid supplementing opening, the hand brake oil inlet communicates with the hand brake pump, and the first oil outlet communicates with the second oil outlet; the first oil outlet communicates with a pressure opening of the rear wheel braking assembly through an oil conveying pipe, the second oil outlet communicates with a pressure opening of the front wheel braking assembly through an oil conveying pipe, and the connecting rod mechanism can drive the piston to move under the action of the braking pedal, so that oil liquid leaves the cavity through the first oil outlet and the second oil outlet. The hand brake oil inlet is used for receiving pressure generated by the hand brake pump, so that oil liquid leaves the cavity through the first oil outlet. The hydraulic pump in the hydraulic braking system integrates a hydraulic distribution function, so that the number of parts required by the hydraulic braking system for realizing hydraulic transmission is smaller, the air tightness of the system is improved, and the braking effect is more stable.
本申请公开了一种全地形车制动系统,包括前轮制动组件、后轮制动组件、制动踏板、手刹泵和液压泵,液压泵包括泵体、活塞机构、连杆机构和弹性机构,泵体开设有手刹进油口、第一出油口、第二出油口和补液口,手刹进油口与手刹泵连通,第一出油口通过输油管与后轮制动组件的压力口连通,第二出油口通过输油管与前轮制动组件的压力口连通,连杆机构能够在制动踏板的作用下驱动活塞移动,使油液通过第一出油口和第二出油口离开腔室,手刹进油口用于接收自手刹泵产生的压力,使油液通过第一出油口离开腔室。该液压制动系统中的液压泵集成了液压分配的功能,使液压制动系统为实现液压传输所需要的部件数量更少,提升系统气密性,制动效果更稳定。
