All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0030] Refer to Figures 1 to 6, this embodiment provides an auxiliary device for suspension performance testing, which is used to perform performance testing on the suspension 300. The auxiliary device includes: a base 100 and two moving adjustment components 200.

[0031] For convenience of description, the wheelbase direction of the suspension 300 is defined as the first direction X, the direction perpendicular to the first direction X in the horizontal plane is defined as the second direction Y, and the direction perpendicular to the first direction X and the second direction Y in the vertical plane is defined as the third direction Z.

[0032] The base 100 includes a fixed seat body 110, a bracket 120, a guide rod 130, a double-headed screw 140, and a motor 150.

[0033] The bracket 120 is arranged on the fixed seat body 110 for installing the suspension 300; the bracket 120 is provided with mounting threaded holes 121 for installing the suspension 300, and the suspension 300 is quickly installed by matching with the mounting threaded holes 121 through screws 310.

[0034] In this embodiment, in order to achieve the quick installation of the suspension 300 and ensure the correct installation position, the bracket 120 is provided with a positioning rod 122 for positioning the installation of the suspension 300, and a limiting plate 123 for limiting the suspension 300 in the third direction Z.

[0035] The guide rod 130 and the double-headed screw 140 both horizontally pass through the fixed seat body 110 along the first direction X; the thread directions of the double-headed screw 140 on both sides of the fixed seat body 110 are opposite, and the driving shaft of the motor 150 is connected to one end of the double-headed screw 140 for driving the double-headed screw 140 to rotate.

[0036] In the first direction X, the two moving adjustment components 200 are respectively arranged on both sides of the fixed seat body 110. Each moving adjustment component 200 includes a moving seat body 210, a telescopic actuator 220, a top plate 230, an adjustment frame 240, and a test plate 250.

[0037] The moving seat body 210 is arranged on the side of the fixed seat body 110, and the moving seat body 210 can perform a reciprocating movement with adjustable position along the first direction X on the fixed seat body 110.

[0038] In this embodiment, a guide sleeve 211 that slidably cooperates with the guide rod 130 is provided on the movable seat body 210. Through the sliding cooperation between the guide sleeve 211 and the guide rod 130, a slidable connection between the movable seat body 210 and the fixed seat body 110 in the first direction X is achieved; a threaded sleeve 212 that is in threaded cooperation with the double-headed screw rod 140 is further provided on the movable seat body 210. The motor 150 drives the double-headed screw rod 140 to rotate, thereby driving the movable seat body 210 to translate in the first direction X along the guide rod 130. By the forward and reverse rotations of the motor 150, a reciprocating motion with adjustable position of the movable seat body 210 along the first direction X on the fixed seat body 110 is achieved; since the thread directions of the double-headed screw rod 140 on both sides of the fixed seat body 110 are opposite, the moving directions of the two movable seat bodies 210 are always opposite.

[0039] In another embodiment, a sliding connection between the movable seat body 210 and the fixed seat body 110 can also be achieved through mechanisms such as a slide rail and the movable seat body 210 is driven to translate reciprocally.

[0042] Guide blocks 241 that slidably cooperate with the guide grooves 231 are provided on both sides of the adjustment frame 240. Through the sliding cooperation between the guide blocks 241 and the guide grooves 231, a slidable connection between the adjustment frame 240 and the top plate 230 along the first direction X is achieved; a threaded hole 243 that is in threaded cooperation with the adjustment screw rod 233 is provided on the bottom surface of the adjustment frame 240. By rotating the adjustment screw rod 233, the adjustment frame 240 can be driven to reciprocate along the guide grooves 231 in the first direction X; in another embodiment, a sliding connection between the adjustment frame 240 and the top plate 230 can also be achieved through mechanisms such as sliding and the adjustment frame 240 is driven to translate reciprocally.

[0043] A rack 242 extending along the first direction X is further provided on the top surface of the adjustment frame 240.

[0044] A rotating shaft 251 extending along the second direction Y is provided on the bottom surface of the test plate 250.

Gears 252 are provided at both ends of the rotating shaft 251, and the gears 252 are meshed and cooperated with the racks 242 on the adjusting frame 240.

[0045] By rotating the adjusting screw 233, the adjusting frame 240 moves horizontally relative to the top plate 230. Since the test plate 250 is meshed and cooperated with the rack 242 on the adjusting frame 240 through the gear 252, the rotating shaft 251 is driven to rotate around the shaft seat 231 on the top plate 230.

[0046] The working principle of an auxiliary device for suspension performance test provided in this embodiment:

[0047] First, align the suspension 300 with the positioning rod 122 on the bracket 120 through the positioning holes 320 thereon to install and position the suspension 300, and then use the screw 310 to cooperate with the installation threaded holes 121 on the bracket 120 to fixedly install the suspension 300 on the bracket 120.

[0048] Then start the motor 150 to drive the double-headed screw 140 to rotate, and then drive the two moving seat bodies 210, the top plate 230, the adjusting frame 240 and the test plate 250 to move towards or away from each other together, and adjust the distance between the two test plates 250 according to the wheelbase of the two wheels 330 of the suspension 300.

[0049] Finally, start the telescopic actuator 220 to make the driving rod of the telescopic actuator 220 extend upward, driving the top plate 230, the adjusting frame 240 and the test plate 250 to move upward together, so that the test plate 250 contacts the wheel 330 of the suspension 300 and starts relevant tests.

[0050] When it is necessary to conduct a lateral force performance test on the suspension 300, by rotating the adjusting screw 233, the adjusting frame 240 moves horizontally relative to the top plate 230. Since the test plate 250 is meshed and cooperated with the rack 242 on the adjusting frame 240 through the gear 252, the rotating shaft 251 is driven to rotate around the shaft seat 231 on the top plate 230, realizing the angle adjustment of the test plate 250 to meet the requirements of lateral force.
