The invention discloses a trailer brake system comprising a drum brake assembly, a differential mechanism, a disc brake assembly, a speed reducer and a brake control device for carrying out brake control on the two brake assemblies. Two wheels of the same axle are respectively connected with transmission half shafts; and the other ends of the transmission half shafts are arranged on the axle. Thedifferential comprises ratchet wheels and a transmission gear; the ratchet wheels are fixedly arranged on the transmission half shafts; the transmission gear is in synchronous meshing transmission with two ratchet wheels arranged on the same axle, the transmission gear is in transmission connection with the input end of the speed reducer, the output end of the speed reducer is in transmission connection with an output shaft. The disc brake system assembly brakes the output shaft, and the brake control device is in synchronous control connection with the drum brake assembly and the disc brake assembly. The drum brake system and the disc brake system are combined, so that the brake performance of the trailer is effectively and comprehensively improved; the brake pressure of drum brake is shared, the brake temperature is reduced; water spraying equipment is not needed, the brake safety is guaranteed; and the structure is simple, and the cost is saved.
本发明公开一种挂车刹车系统,包括鼓式刹车总成、差速器、碟式刹车总成、减速器以及对两刹车总成进行制动控制的制动控制装置,同一车桥的两个车轮分别连接有传动半轴,传动半轴的另一端设置在车桥上,差速器包括棘轮和传动齿轮,棘轮固定设置在传动半轴上,传动齿轮与设置在同一车桥的两个棘轮同步啮合传动,传动齿轮与减速器的输入端传动连接,减速器的输出端传动连接有一输出轴,碟刹系统总成对输出轴进行制动,制动控制装置与鼓式刹车总成、蝶式刹车总成同步控制连接。本发明结合鼓刹系统和碟刹系统,有效综合提高挂车的刹车性能,分担鼓式刹车的制动压力,降低刹车温度,不需要使用淋水设备,保障刹车的安全,且结构简单节约成本。
