The invention provides a light truck rear axle structure with an EPB (electronic parking brake), which comprises a rear axle, a plate spring mounting seat arranged on one side of the rear axle, a drum-type EPB parking brake arranged on one side, far away from the plate spring mounting seat, of the rear axle, calipers and a calipers mounting bracket for connecting the calipers and the drum-type EPB parking brake, the brake disc is arranged on the drum type EPB parking brake, the hub is far away from one side of the calipers, the half shaft, the brake disc and the hub are connected through wheel bolts, the drum type EPB parking brake is composed of an in-disc drum parking device, a bent motor support and a motor, the gear ring is fixed on the brake disc, the brake disc is arranged on the brake disc, the hub is far away from one side of the calipers, and the half shaft, the brake disc and the hub are connected through wheel bolts. According to the novel arrangement form of the wheel speed sensor penetrating through the drum type EPB parking brake, the problem that EPBs of large-tonnage vehicle types, especially commercial vehicle types with plate spring seats, are difficult to arrange is solved, and the feasible scheme that the large-tonnage vehicle types are provided with the EPBs is achieved.
本发明提供一种带EPB的轻卡后桥结构,包括后桥、设置在后桥一侧的板簧安装座、设置在后桥远离板簧安装座一侧的鼓式EPB驻车制动器、卡钳、用于连接卡钳和鼓式EPB驻车制动器的卡钳安装支架,以及设置在所述鼓式EPB驻车制动器的制动盘和远离所述卡钳一侧的轮毂、半轴,制动盘与轮毂之间通过车轮螺栓连接,通过采用由盘中鼓驻车器、弯曲形状的电机支架与电机组成的鼓式EPB驻车制动器、固定在制动盘上的齿圈,贯穿鼓式EPB驻车制动器的轮速传感器的新颖布置形式,解决了大吨位车型特别是带板簧座的商用车型EPB难布置问题,实现了大吨位车型配备EPB的可行方案。
