The invention discloses a novel drum brake front axle wheel end structure which comprises a rim, a brake drum, an outer hub, a steering knuckle, an inner hub, an ABS sensor and a brake shoe. The brake drum is connected with the outer hub through fastening bolts, and the rim is in lap joint with the outer side of the outer hub. The steering knuckle is arranged in the inner hub, a brake shoe is further arranged on the outer side wall of the inner hub, a friction plate is arranged at the end of the brake shoe, and the friction plate is matched with the inner side of the brake drum; the inner hub and the outer hub are mounted and fixed through hub connecting bolts; a locking nut is arranged at one end, facing the outer hub, of the steering knuckle; an ABS gear ring is further arranged at the end, away from the outer hub, of the inner hub, the ABS sensor is arranged on the outer side of the end, away from the locking nut, of the steering knuckle, and a sensing head of the ABS sensor penetrates through the steering knuckle and corresponds to the ABS gear ring. According to the invention, the problem of bearing damage caused by disassembly of the hub, the inner bearing and the outer bearing when the friction plate is replaced and the ABS sensor fault is checked can be effectively avoided.

    本发明公开了一种新型鼓式制动器前桥轮端结构,包括轮辋、制动鼓、外轮毂、转向节、内轮毂、ABS传感器以及制动器蹄铁;制动鼓与外轮毂通过紧固螺栓连接,轮辋搭接在外轮毂的外侧。转向节设置在内轮毂的内部,内轮毂的外侧壁上还设有制动器蹄铁,制动器蹄铁的端部设有摩擦片,摩擦片与制动鼓的内侧相配合;内轮毂和外轮毂通过轮毂连接螺栓安装固定;转向节面向外轮毂的一端设有锁紧螺母;内轮毂远离外轮毂的一端还设有ABS齿圈,ABS传感器设置在转向节远离锁紧螺母的一端外侧,ABS传感器的感应头穿过转向节并与ABS齿圈相对应。本发明可有效避免更换摩擦片及检查ABS传感器故障时,拆解拆除轮毂、内轴承以及外轴承造成轴承损坏的问题。
