Description

Technical Field

[0001] The utility model relates to the technical field of wheel fastening devices, in particular to a wheel fastening device of a whole vehicle four-post road simulation test bench. Background Art

[0002] The four-post road simulation test bench for whole vehicle is used to completely or partially simulate the vibration environment of the whole vehicle when it is driving on the road, as well as the driving conditions of the vehicle under different road conditions. It can perform durability tests on the whole vehicle, car body, frame and on-board equipment, and can perform dynamic response tests on the car body, frame and on-board equipment.

[0003] The existing Chinese patent application number CN202021240606.X is a wheel limiting device for a four-column road simulation test bench, which is composed of a rolling limiting mechanism and a tray. The limiting mechanism is a rolling limiting mechanism, which is composed of two groups of symmetrically arranged transverse limiting components and a longitudinal limiting component vertically and symmetrically arranged between the two ends of the transverse limiting component. The longitudinal limiting assembly, the longitudinal limiting roller is rotatably sleeved on the longitudinal round rod; the axial end faces of the wheel tire are in rolling contact with the longitudinal limiting roller; the transverse limiting assembly, the transverse limiting roller is rotatably sleeved on the transverse round rod; the radial two side faces of the wheel are in rolling contact with the transverse limiting roller; the longitudinal limiting assembly and the transverse limiting assembly are both fixedly mounted on the upper surface of the tray through a longitudinal connecting frame. The utility model enables rolling contact between the tire and the limiting structure, while achieving effective limiting, avoiding excessive wear of the tire, and greatly reducing the safety hazards of the test. However, when it is officially used, the locking nut located on the adjacent surface of the longitudinal connecting frame will cause a certain obstruction to the tire, so that the tire cannot completely contact the transverse limiting roller, thereby causing friction between the tire and the locking nut, causing serious wear on the tire. When the device needs to be maintained, the limiting roller needs to be removed before the limiting structure can be separated from the pallet, which is cumbersome. For this reason, we propose a wheel fastening device for a four-post road simulation test bench for a whole vehicle. Utility Model Content
