Automobile supporting rear axle assembly

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of automobile parts, in particular to an automobile supporting rear axle assembly. Background technique [0002] The drive axle is the main component of the chassis drive train of automobiles and wheeled construction machinery, and the axle housing is the base of the drive axle, which transmits the weight of the vehicle to the wheels and transmits various forces acting on the wheels to the frame , therefore, the axle housing is the main stressed part of the vehicle and should have sufficient strength and rigidity. [0003] There are also some technical solutions about auto parts in the prior art. For example, a Chinese patent with application number 2017101384074 discloses an automobile supporting rear axle assembly, including axle tube, axle head, connecting plate, brake and rear axle assembly. The two ends of the shaft tube are welded with the shaft head through the connecting plate, the brake is installe...

AI Technical Summary

Problems solved by technology

[0006] In order to make up for the deficiencies of the existing technology, the rear axle assembly in the prior art bears the functions of driving the vehicle and loading the vehicle, but the rear axle tube is elastically deformed and bent when the vehicle is heavily loaded, especially at high speeds under complex road conditions During driving, the axle tube is subjected to repeated vehicle loads and impact loads caused by road bumps, which makes the axle tube easily deformed and bent after long-term use. The existing technology cannot monitor and record the deformation of the axle tube. It is easy to produce plastic bending or even fracture when a huge impact or overload occurs, which seriously affects the driving safety of the vehicle. The invention proposes an automobile supporting rear axle assembly
