A motor vehicle axle capable of changing stress state

Abstract

The invention discloses a motor vehicle axle capable of changing a stress state. The motor vehicle an axle and first inclination angles, a first stress prevention structure is arranged in the middleof the axle; and a second stress prevention structure and a third stress prevention structure are installed on the left side and the right side of the first stress prevention structure correspondingly, the first inclination angles are arranged on the outer surfaces of the left side and the right side of the axle, axle seats are arranged on the outer sides of the first inclination angles, and second inclination angles are arranged on the outer sides of the axle seats. By means of the first stress prevention structure, the second stress prevention structure and the third stress prevention structure, stress protection can be conveniently conducted on the middle section of the axle; therefore, the axle can be prevented from being broken and damaged when being bent and impacted, meanwhile, theservice life of the axle can be prolonged, meanwhile, the stress prevention structure can be disassembled through the connecting bolts, and therefore the convenience of device overhauling can be improved, and maintenance personnel can conveniently disassemble the stress prevention structure to explore the damage degree of the axle.

Description

technical field [0001] The invention relates to the technical field of motor vehicle axle devices, in particular to a motor vehicle axle with changing stress state. Background technique [0002] Axle refers to the cylindrical part that penetrates into the hub to bear the weight of the vehicle body, and can also refer to the car. The axle (also known as the axle) is connected to the frame (or load-bearing body) through the suspension, and the car wheels are installed at both ends. Its function is to transmit the forces in all directions between the frame (or load-bearing body) and the wheels. A motor vehicle is a wheeled vehicle driven or towed by a power unit, running on the road, used for passenger or (and) transporting items or performing special operations, and some amusement facilities (such as electric parking cars, electric scooters, electric bicycles, etc.). It can be classified into automobiles and automobile trains, motorcycles and mopeds, tractor transport units...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a motor vehicle axle with a changeable stress state, which solves the problem that the existing traditional motor vehicle axle cannot adjust and change the stress change during use, which will cause the axle to be stretched under long-term stress. The problem of fracture under pressure and pressure, and it also affects the work of maintenance personnel during the inspection and maintenance of the axle, which is not conducive to the problem of overhaul and maintenance of the main stress-bearing parts
