Description

A bearing assembly for drive axle assembly test

technical field

The utility model relates to a support assembly for a drive axle assembly test.

Background technique

At present, during the fatigue, static torsion, noise and temperature rise tests of the drive axle assembly, two identical bases are placed at the leaf spring seat, and the drive axle is fixed on the base. Since the size of the drive axle assembly is different, it is necessary to be equipped with a variety of bases of different sizes, so as to replace the base that matches the size of the drive axle during the test. However, since the height of the power output end of the test bench is not adjustable, it is difficult to meet the exact match between the input end of the drive axle assembly and the power output end of the test bench. Although it can be adjusted by adding or subtracting backing plates, this method is not only inconvenient for assembly , and it is still difficult to meet the coaxial contour of the input end of the drive axle assembly and the power output end of the test bench to a certain precision. Therefore, during the fatigue test, the input shaft bearing is easily damaged in the early stage; during the static torsion test, the torque measurement value contains added value; during the noise test, the measured value is too large; during the temperature rise test, the temperature at the input shaft is too high. If a new base is processed, it will not only affect the test period, but also increase the test cost, which is the deficiency in the prior art.

Contents of the invention

The technical problem to be solved by the utility model is to provide a test support assembly for the drive axle assembly that can be adjusted in the horizontal, vertical, and up and down directions in view of the deficiencies in the prior art.

This solution is achieved through the following technical measures: the drive axle assembly test support assembly includes a fixed frame, the upper end of the fixed frame is equipped with a group of lateral adjustment brackets that can move laterally along it, and the lateral adjustment bracket includes a horizontal The adjustment base plate and the horizontal adjustment column fixed at one end of the horizontal adjustment base plate are installed with an up and down adjustment bracket that can move up and down along the horizontal adjustment column, and a telescopic support rod is installed on the horizontal adjustment base plate, and the upper end of the telescopic support rod is fixed with the up and down adjustment bracket connection; the two sides of the fixed frame are respectively fixedly connected with a group of longitudinal adjustment feet.

The above-mentioned vertical adjustment bracket includes a load-bearing bracket and a positioning bracket clamped with the horizontal adjustment column. The load-bearing bracket and the positioning bracket are connected by bolts.

The above-mentioned fixed frame is fixedly connected with a traversing backing plate, and a plurality of through holes I are arranged on the traversing backing plate, and through holes II cooperating with the through holes I are arranged on the lateral adjustment base plate.

The beneficial effect of this scheme can be known from the description of the above-mentioned scheme. In the support assembly for the drive axle assembly test, the lateral relative position of the input end of the drive axle assembly and the power output end of the test bench can be adjusted and adjusted through the horizontal adjustment bracket. , adjust the vertical relative position between the input end of the drive axle assembly and the power output end of the test bench by adjusting the bracket up and down, and adjust the longitudinal distance between the drive axle assembly and the test bench by adjusting the feet vertically. The support assembly can conveniently adjust the position between the drive axle assembly and the test bench according to different drive axle assemblies, so as to meet the drive axle assemblies with different leaf spring distances and different heights, so that the input end of the drive axle assembly The coaxial contour with a certain precision with the power output end of the test bench has strong versatility, convenient assembly and adjustment, accurate test data, and effectively saves test costs. It can be seen that, compared with the prior art, the utility model has substantive features and progress, and the beneficial effects of its implementation are also obvious.
