A rubber bushing test system

Abstract

The invention relates to the technical field of auto parts testing, and discloses a rubber bushing test system, which includes a loading seat, a warping seat and a twisting seat; the loading seat is provided with accommodating holes for press-fitting rubber bushings, and the loading seat is covered by It is configured to be able to apply a radial load to the rubber bushing; the warping seat includes a connecting rod, which is used to pass through the inner hole of the rubber bushing to fix the rubber bushing on the warping seat, and the warping seat can be wound vertically The direction of the axis of the connecting rod rotates, and the warping seat is configured to apply a warping load to the rubber bushing; the warping seat is rotatably connected to the torsion seat, and the torsion seat can rotate around the axis of the connecting rod, and the torsion seat is configured to apply a warping load to the rubber bushing. The sleeve applies a torsional load. The rubber bushing test system achieves mechanical decoupling, and can apply three dynamic loads of radial, torsional and warping to the rubber bushing at the same time. The installation and connection method of the rubber bushing is consistent with that of the real vehicle, which can truly simulate the rubber bushing. The actual working condition of the sleeve is used to accurately test the rubber bushing.

Description

technical field [0001] The invention relates to the technical field of auto parts testing, in particular to a rubber bushing testing system. Background technique [0002] With the development of the automobile industry, people have higher and higher demands on automobiles in terms of energy saving, environmental protection, comfort and reliability. [0003] In the guiding device of the suspension system (such as: swing arm, rear axle, etc.), the hinge point connected with the body is more and more connected by rubber bushing. Rubber bushing has become an indispensable and important component in automobiles due to its good vibration isolation performance, elastic characteristics and attenuation characteristics. [0004] At present, there are mainly two types of test institutions for this type of rubber bushing. One is to conduct radial or torsion or warping equal-amplitude tests on rubber bushings alone, but the loading form is single, which is inconsistent with the actual s...

Problems solved by technology

[0004] At present, there are mainly two types of test institutions for this type of rubber bushing. One is to conduct radial or torsion or warping equal-amplitude tests on rubber bushings alone, but the loading form is single, which is inconsistent with the actual stress state and cannot be restored. The correct failure mode; the second is to use the method of twisting the rotating shaft and then radially loading the bushing with a linear actuator in the middle, but this method still lacks warping loads, and it will occur when radial and torsional loads are applied simultaneously Interference, leading to difficulty in test control and imprecise results
