Problems solved by technology

[0003] Automobile transmission shaft and steering system are important components of automobiles, which are the key components to determine the safety and reliability of automobile driving. There are two types of reducers, which usually can only undertake static torsion tests of various transmission shafts, and the utilization rate of the test bench is very low during the short-term test process. It can be used for static torsional stiffness and torsional strength tests of automotive drive shafts, structural parts and shaft parts; However, it cannot meet the dynamic torsional fatigue life test of the automobile drive shaft, and this test is to test whether the drive shaft assembly meets the design performance index requirements, which is a problem that people pay more attention to.

Abstract

The invention discloses a dynamic torsional fatigue tester for automobile transmission shaft assemblies. The dynamic tester comprises a support and a base disposed within a box. One end of the base is provided with a main reduction drive mechanism, and the other end thereof is provided with a dynamic torsional mechanism. Space between the main reduction drive mechanism and the dynamic torsional mechanism is used for clamping a transmission shaft assembly to be tested. The dynamic torsional mechanism is provided with a loading mechanism. By programming through a control panel, a motor is allowed to drive a spindle to rotate (positively and reversely in turn); the transmission shaft assembly transmits power to a driven shaft; a servo motor drives a steering wheel to rotate to a certain angle, a loading wheel applies certain resistance, and various normal running states of an automobile are simulated: starting, accelerating, turning, parking and the like; thus, the service life and fatigue strength of the transmission shaft assembly during the automobile running is tested.

Description

technical field [0001] The invention belongs to the technical field of automobile power transmission driving experiment system, and in particular relates to an automobile transmission shaft assembly [0002] into a dynamic torsional fatigue test device. Background technique [0003] Automobile transmission shaft and steering system are important components of automobiles. They are the key components that determine the safety and reliability of automobile driving. There are two types of automobile transmission shaft test benches: hydraulic pressure and reducer. Usually, they can only bear the static pressure of various transmission shafts. Torsion test, the utilization rate of the short-term test bench is very low during the experiment process, and it can be used for static torsional stiffness and torsional strength experiments of automobile transmission shafts, structural parts and shaft parts; but it cannot meet the dynamic torsional fatigue life test of automobile transmi...
