Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a vehicle rear axle detection device. Background Art

[0002] The rear axle is the rear drive shaft that transmits power to the vehicle. It consists of two half-axles, each capable of differential speed. Testing a vehicle's rear axle requires a testing device.

[0003] In the prior art, Chinese patent publication number CN218270540U discloses a vehicle rear axle detection device, which adopts a scheme of "including a platform box and a movable plate, wherein the movable plates are inserted through both ends of the platform box, and a side plate is vertically fixedly installed at one end of the movable plate, and a measuring device is fixedly installed on one side surface of the side plate, and the measuring device includes an outer cylinder, a guide column and a thimble". This scheme adopts a measuring device. After the rear axle of the vehicle is horizontally installed, the side plate is moved until the thimbles of all the measuring devices abut against the wheel mounting plate of the rear axle of the vehicle, and then the drive motor can be started to rotate in the opposite direction. By comparing the scale difference of the thimbles of the measuring devices distributed above and below, the camber difference of the wheel mounting plate of the rear axle of the vehicle can be obtained, and the camber angle can be calculated. At the same time, by comparing the scale difference of the thimbles of the detectors distributed left and right, the toe difference of the wheel mounting plate of the rear axle of the vehicle can be obtained, and the toe angle can be calculated. The scheme has a simple structure, low cost, and easy operation, eliminates the use of various sensors, and the detection is quick and convenient.

[0004] However, the above scheme still has some shortcomings. For example, during the actual inspection of the rear axle of the automobile, the detection device can only detect the toe difference of the wheel mounting plate of the rear axle of the automobile. It cannot detect whether the exterior of the rear axle of the automobile is worn or cracked at the welding part. It is also unable to detect whether the structure of the rear axle shell of the automobile is damaged, resulting in low applicability of the device.

[0005] In view of this, the utility model proposes a vehicle rear axle detection device. Utility Model Content
