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

Abstract

The invention belongs to the technical field of auto parts, and specifically relates to an automobile supporting rear axle assembly, including a shaft tube, a brake air bag, a brake, a wheel hub and a leaf spring; Arranged at the bottom, one end of the steel rope is fixedly connected to the end of the shaft tube, and the other end is fixedly connected to a tie rod after passing through the support plate set in the shaft tube; There is a spring; the end of the pull rod far away from the spring is fixedly connected with a movable contact through a shrapnel, and an insulated slide rail is fixedly connected with the position corresponding to the movable contact in the shaft tube, and a set of static contacts are uniformly inlaid on the slide rail. The points are all connected to the controller through wires; the middle part of the shaft tube of the present invention is bent downward, and the steel rope pulls the pull rod to change the relative position of the static contact and the moving contact, and the elastic deformation and plastic deformation of the shaft tube are monitored by the controller, and then The abnormal bending of the axle tube can be detected in time, and timely maintenance can be carried out to ensure the safe and stable operation of the rear axle of the car.

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...
