The invention belongs to the technical field of automobile parts, and particularly relates to an automobile supporting rear axle assembly which comprises an axle tube, a brake air bag, a brake, a hub and a plate spring. A steel rope is arranged in the axle tube and close to the bottom of the axle tube, one end of the steel rope is fixedly connected with the end of the axle tube, and the other end of the steel rope penetrates through a supporting plate arranged in the axle tube and then is fixedly connected with a pull rod; the middle part of the pull rod is fixedly connected with a limiting plate, and a spring sleeves the pull rod between the limiting plate and the supporting plate; the end, away from the spring, of the pull rod is fixedly connected with a movable contact through an elastic piece, the position, corresponding to the movable contact, in the axle tube is fixedly connected with an insulated sliding rail, a set of static contacts are evenly embedded in the sliding rail, and the movable contact and the static contacts are connected with a controller through wires. The middle of the axle tube is bent downwards, the steel rope pulls the pull rod to change the relative position of the static contacts and the movable contact, elastic deformation and plastic deformation of the axle tube are monitored through the controller, then abnormal bending of the axle tube is found in time, maintenance is conducted in time, and safe and stable work of the automobile rear axle is guaranteed.

    本发明属于汽车零部件技术领域,具体的说是一种汽车支承后桥总成,包括轴管、制动气包、制动器、轮毂和板簧;轴管内设有钢绳,钢绳靠近轴管底部布置,钢绳一端与轴管端部固连,另一端贯穿轴管内设置的撑板后固连有拉杆;拉杆中部固连有限位板,限位板与撑板之间的拉杆上套设有弹簧;拉杆远离弹簧的一端通过弹片固连有动触点,轴管内与动触点对应位置固连有绝缘的滑轨,滑轨上均匀镶嵌有一组静触点,动触点和静触点均通过导线连接控制器;本发明轴管中部向下弯曲,钢绳拉动拉杆改变静触点与动触点的相对位置,通过控制器对轴管的弹性变形和塑形变形进行监测,进而及时发现轴管的异常弯曲,及时检修,保证汽车后桥的安全稳定工作。
