[0017] Figure 1 is a schematic structural diagram of the detection tool for the installation height of the road wheel shaft according to the embodiment of the present invention;

[0018] Figure 2 is a schematic use diagram of the detection tool for the installation height of the road wheel shaft according to the embodiment of the present invention. Detailed Embodiments

[0019] To make the objectives, contents, and advantages of the present invention clearer, the following further describes in detail the specific embodiments of the present invention with reference to the drawings and embodiments.

[0020] This embodiment provides a detection tool for the installation height of a road wheel shaft, and its structure is as Figure 1 shown, including a bushing 1, a connecting plate 2, a connecting rod 3, a support 4, a sliding angle gauge 5, screws 6, and nuts 7.

[0021] The bushing 1 and the connecting rod 3 are respectively made of hollow steel pipes. The connecting plate 2 is a T-shaped metal structure with reinforcing ribs. The lower ends of the connecting plate 2 and its reinforcing ribs are welded to the bushing 1, and the upper ends of the connecting plate 2 and its reinforcing ribs are welded to the connecting rod 3 to form the main body of the detection tool.

[0022] The lower end of the support 4 is an installation shaft, and the upper end has a dovetail groove. The lower end of the support 4 is inserted into the inner hole of the connecting rod 3 through the installation shaft. Two coaxial threaded through holes are machined on both sides of the dovetail groove of the support 4. The sliding angle gauge 5 is installed in the dovetail groove and fixed through the threaded through holes on both sides of the dovetail groove by screws 6 and nuts 7.

[0023] The installation shaft of the support 4 and the connecting rod 3 have a small clearance fit. When detecting, rotating the support 4 can drive the sliding angle gauge 5 to approach the reference wire 8 on the vehicle body, which is convenient for reading the detection value.

[0024] During actual use, as Figure 2 shown, the bushing 1 of the detection tool is sleeved on the idler wheel shaft 9. Rotating the idler wheel shaft 9 drives the detection tool to change in the vertical direction. Rotating the support 4 makes the scale of the sliding angle gauge 5 close to the reference wire 8 on the vehicle body. The scale line value corresponding to the reference wire 8 is the installation height of the corresponding idler wheel shaft 9. When the installation height of the idler wheel shaft 9 is adjusted to the required value, the balance elbow is fixed, and the detection of the installation height of the idler wheel shaft is completed.

[0025] The reference wire 8 on the vehicle body is 150 mm higher than the rotation center of the idler wheel shaft 9. The distance from the groove surface of the support 4 of the detection tool to the center of the bushing 1 is 350 mm. The 200 mm mark on the scale of the sliding angle gauge 5 is flush with the groove surface of the support 4. At this time, the scale reading is the value of the installation height of the idler wheel shaft 9. Rotating the support 4 to make the scale close to the reference wire 8, and the scale line value read at this time is the installation height value.

[0026] The present invention realizes the universality of the detection tool and can also detect the specific deviation value between the installation height and the theoretical installation height through the scale reading.

[0027] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
