The invention discloses a driven axle braking system. The driven axle braking system is installed on a transmission shaft of a driven axle and used for braking a hub on the transmission shaft. The driven axle braking system comprises a closed shell, a braking body and a transmission wheel, wherein the transmission shaft is sleeved outside the transmission wheel, the transmission wheel is connectedwith the hub and used for transmitting the braking force transmitted by the braking body to the hub, a containing cavity is formed among the closed shell, the hub and the transmission shaft, and thecontaining cavity is filled with cooling liquid. The driven axle braking system is advantaged in that the braking body is contained in the closed shell, and the containing cavity is filled with the cooling liquid so that when the braking body is in an oil-immersed closed environment, the braking system forms infiltration type braking, heat generated by braking is taken away by the cooling liquid,good heat dissipation performance is achieved, and the maintenance frequency is reduced; the brake body is located in the closed structure, the annular working area is large, impurities such as mud, water and oil are prevented from immersing, pollution and abrasion of parts are reduced, and maintenance can be avoided.

    本发明公开了一种从动桥制动系统,该从动桥制动系统安装于从动桥的传动轴上用于制动传动轴上的轮毂,从动桥制动系统包括封闭壳体、制动体和传动轮,传动轮套设在传动轴外,传动轮与轮毂连接用于将制动体传递而来的制动力传递给轮毂,封闭壳体、轮毂和传动轴之间形成收容腔,收容腔内填充有冷却液。本发明公开的从动桥制动系统通过将制动体收容在封闭壳体内并在收容腔内填充冷却液,使制动体在浸油的封闭环境中,制动系统形成一种浸润式制动,制动产生的热量被冷却液带走,具有良好的散热性能,减少了维修保养的次数;制动体位于封闭结构内,环形工作面积较大,且防止泥、水、油等杂质的浸入,减少了零部件的污染和磨损,可免于维护。
