Description

Technical Field

[0001] The utility model relates to the technical field of automobile differential strength testing, in particular to an automobile differential strength testing device. Background Art

[0002] The automobile differential is a mechanism that enables the left and right (or front and rear) drive wheels to rotate at different speeds. It is mainly composed of left and right half-axle gears, two planetary gears and a gear rack. Its function is to make the left and right wheels roll at different speeds when the car is turning or driving on uneven roads, that is, to ensure that the drive wheels on both sides perform pure rolling motion. The differential is installed to adjust the speed difference between the left and right wheels. In order to make the rotation speed of the car basically consistent when driving in a curve, it is necessary to add an intermediate differential to adjust the speed difference between the front and rear wheels.

[0003] The strength performance test of automobile differential is particularly important. Whether it is the impact resistance or wear resistance of automobile differential, it is necessary to conduct strength test under strength test equipment to verify whether the automobile differential meets the production qualification standards. The existing automobile differential strength test device generally only performs strength test on the automobile differential by applying pressure. When the automobile differential is actually used, a certain temperature will be generated during its operation. Under the influence of temperature, the automobile differential may have different conditions, resulting in inaccurate test results only by applying pressure. At the same time, the existing automobile differential strength test device is difficult to adapt to the detection of automobile differentials of different specifications and lengths.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
