DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 A motor vehicle suspension inspection device comprises a box body 1 with symmetrical openings at both ends. When the parts in the box body 1 need to be maintained, they only need to be maintained at the openings. At the same time, a universal wheel 2 is installed at the bottom of the box body 1 to facilitate the adjustment of the position of the box body 1. Four guide sleeves 3 are fixedly installed on the upper end of the box body 1. Support columns 4 are slidably sleeved in the four guide sleeves 3, and a fixing mechanism for fixing and clamping the tire of the motor vehicle is fixedly installed on the upper end of the support column 4. A lifting mechanism for pulling the fixing mechanism for reciprocating movement in the vertical direction is arranged in the box body 1. A push plate 5 is welded at the bottom end of the support column 4, and the lifting mechanism is fixedly installed on the box body 1 through the push plate 5.

[0021] The fixing mechanism includes a support plate 6 welded to the guide sleeve 3, and the bottom end of the support plate 6 is open, and two square notches penetrating the support plate 6 are opened at the same time. A first fixing plate 7 is welded to the bottom end of the support plate 6, so that it can move synchronously with the support column 4 without affecting the vertical reciprocating movement of the entire fixing mechanism. A first driving motor 8 is fixedly installed on the first fixing plate 7, and a driving gear 9 is matched with the output end of the first driving motor 8. Two transmission racks 10 meshing with the driving gear 9 are slidably installed at the lower end of the support plate 6. The two transmission racks 10 are centrally symmetrically arranged at the two sides of the driving gear 9. When the driving gear 9 is rotated clockwise, the two transmission racks 10 move toward each other, which is a fixed clamping, and vice versa, it is a movable release;

[0022] A fixed clamping plate 11 is welded on each of the two transmission racks 10, and four strong springs 12 are welded on the fixed clamping plate 11. A silicone plate 13 is welded on the other end of the four strong springs 12. The silicone plate 13 is fixedly connected with a limiting column 14 that slides through the fixed clamping plate 11. The limiting column 14 controls the sliding path of the silicone plate 13 while also limiting the strong springs 12. The silicone plate 13 and the strong springs 12 can effectively prevent the extrusion and damage to the wheels of the motor vehicle during the fixed clamping process.

[0023] The lifting mechanism includes a second fixed plate 15 welded to the bottom end of the box body 1, a second drive motor 16 is fixedly installed on the second fixed plate 15, two movable plates 17 are fixedly installed at the output end of the second drive motor 16, circular plates for free rotation are provided in the two movable plates 17, and the circular plates are eccentrically connected to the output end of the second drive motor 16, a transmission bar 18 is connected to the pin shaft between the two movable plates 17, and the transmission bar 18 is pulled to perform cyclical motion through the coordinated movement of the two movable plates 17, and a guide long hole 22 is opened at the middle end of the transmission bar 18, a support bar 19 connected to one end of the transmission bar 18 by a pin shaft is installed in the box body 1, a third fixed plate 20 is welded in the box body 1, and a traction column 21 fixed to the push plate 5 and slidably sleeved in the guide long hole 22 is provided in the third fixed plate 20.

[0024] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated.

[0025] The functional principle of the utility model can be explained through the following operation modes:

[0026] The motor vehicle is suspended and placed, and the first drive motor 8 is started. The output end of the first drive motor 8 drives the drive gear 9 to rotate clockwise, thereby driving the transmission rack 10 to move inward, and the fixed clamping plate 11 welded to the transmission rack 10 is clamped inward, and the silicone plate 13 is attached to the wheel under the traction of the fixed clamping plate 11. At this time, the strong spring 12 is compressed, and the first drive motor 8 is turned off;

[0027] By starting the second drive motor 16, the output end of the second drive motor 16 drives the two movable plates 17 to make circular motion, pulling the transmission bar 18 connected to the movable plate 17 to make periodic motion, and the transmission bar 18 drives the traction column 21 to make a reciprocating lifting motion, thereby pulling and driving the fixing mechanism to make a reciprocating lifting motion, thereby achieving the effect of simulating bumpy road conditions.
