Abstract

The invention discloses a bending test device for a semi-floating drive axle, and a method for performing the bending test on the semi-floating drive axle by the bending test device, belonging to the technical field of automobile manufacturing. A bending test device for the semi-floating drive axle, which can meet the stressing features of the semi-floating drive axle in the semi-floating drive axle bending test, and a method for performing bending test on the semi-floating drive axle by the test device, are provided. A wheel simulator is arranged on the chassis of each support frame for test of a support frame group; when the vertical bending rigid test, the vertical bending static strength test and the vertical bending fatigue test of the semi-floating drive axle are performed, after the semi-floating drive axle sample is connected with the wheel simulators, a workbench for test is supported by the chassis, and a test support counter force identical to the actual service condition is applied on the semi-floating drive axle through the wheel simulators.

Description

technical field [0001] The invention relates to a bending test device, in particular to a bending test device for a semi-floating drive axle, belonging to the technical field of automobile manufacturing. The present invention also relates to a method for performing a bending test on the semi-floating drive axle by using the bending test device. Background technique [0002] The semi-floating drive axle is an integral drive axle, which is widely used in cross-type passenger cars, light vans and off-road vehicles. [0003] Compared with the full-floating drive axle widely used in large vans, the semi-floating drive axle has a simpler structure, fewer components, easier manufacturing and assembly, and lower cost. Due to its convenience in the arrangement and installation of wheel rims, semi-floating drive axles are widely used in light-duty vehicles. However, due to the complex force on the half shaft, the reliability is lower than that of the full floating half shaft drive a...
