The comprehensive inspection test bench is advantaged in thatthe clamping structure is utilized, the comprehensive inspection test bench is stable and is convenient to adjust, and a safety protection device is further arranged.

Description

technical field [0001] The invention relates to the technical field of automobile production testing devices, in particular to a comprehensive testing test bench for a rear axle assembly of a commercial vehicle. Background technique [0002] Automobiles play an increasingly important role in people's modern life and social development, and people have higher and higher requirements for automobile performance and quality. The rear drive axle of an automobile is a key assembly in an automobile, with a complex structure and many parts and components. , its important function is to transmit power, reduce speed and increase torque, its basic requirements are smooth transmission, low noise, long life, and the power transmission of the drive axle is completed by many gear pairs, which need to be adjusted during assembly, and the assembly quality is directly It affects the noise and service life of the drive axle, so the drive axle needs to be tested by a corresponding test bench af...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a comprehensive detection test bench for commercial vehicle rear axle assembly to solve the problem that the drive axle proposed in the above background technology is generally detected through the corresponding detection test bench, because the drive axle needs to be connected to the motor for detection. High-speed rotation, when encountering unevenly assembled drive axles, severe vibrations will occur. The structure of the existing test bench to clamp and fix the drive axle is relatively thin, and the drive axle is easy to slip and cause damage to the device. Without protective measures, unqualified drive axles may be damaged and burst due to high-speed transmission, hurting staff, and lower safety issues
