Working condition experimental device of automotive front driving shaft

Abstract

The invention discloses a working condition experimental device of an automotive front driving shaft. The working condition experimental device comprises a drive system, a resistance system, a base and a friction block, wherein the drive system comprises a drive device and a spline connection end connecting the drive device with the mounting end of a drive semi-shaft inner ball cage; and the resistance system is fixed on the base and is provided with a first spline connection end connected with the mounting end of the drive semi-shaft outer ball cage, and the friction block is contacted with a spindle of a second spline connection end. A model automobile eight-shaped curve road experiment of the device can be used for effectively detecting whether the problems of quality and design exist in the semi-shaft; and the whole device is simple in structure, convenient in assembly and fast and efficient in checking process, quality and efficiency of check on the drive semi-shaft are improved, and checking cost and working intensity and difficulty of checking operation are reduced.

Description

technical field [0001] The invention relates to an experimental device for a front drive shaft of an automobile; more specifically, it relates to an experimental device for simulating the working condition of the front drive shaft in a "8" curve road test. Background technique [0002] The front drive shaft of a car is a safety component on a car. If there is a serious quality problem, it may cause serious consequences of car crash. In order to avoid production quality defects, the quality of the half shaft must be checked during the design and manufacturing process. Carry out preventive verification, find out in advance the quality hidden dangers in the design or manufacturing process of the half shaft, and reduce the risk to the final consumer. Verify the quality defect, find out the problem and change it in time to minimize the risk; at the same time, it can also reproduce the fault of the drive shaft returned from the main engine factory to the half shaft manufacturer, s...

AI Technical Summary

Problems solved by technology

[0003] At present, there is no professional inspection equipment for the experiment of the front drive axle shaft. Usually, the half axle is assembled on the car for "8" curve road test, which can detect the work of the front drive axle under various normal and limit states. However, when the semi-shaft after assembly is subjected to the "8" curve road test, if there is any quality problem with the half-shaft, it can only be According to the original method of dismantling, analyzing, and discussing to make a judgment, not only the efficiency is low, but the work skills and experience of the analysis staff are high, and it can only be processed and corrected after the event, and cannot be prevented and verified in advance. , will bring more troubles and quality improvement lags to half shaft manufacturers
