Automobile cross-country escape capability test roller support

Abstract

The invention relates to an automobile cross-country escape capability test roller support which comprises a frame, two slope bodies, at least two rollers and a locking mechanism, and is characterizedin that the frame comprises two side fences, the top end, the front end and the rear end of the frame are open, and the two slope bodies are respectively positioned at the near front end and the nearrear end in the frame; the rollers are rotationally connected between the fences on the two sides; and the locking mechanism plays a role in locking / unlocking the rotation of the rollers. According to the automobile cross-country escape capability test roller support, even if the roller support is placed under wheels on flat non-paved road surfaces or non-road road conditions such as muddy lands,earth roads and sand lands, the wheels located on the roller support do not make contact with the ground and slide and rotate in situ, forward or backward driving force is not provided, and the wheelslip condition of vehicle during cross-country process can be simulated, and the vehicle can be designed to be placed in various escape modes, and the escape capacity of the vehicle on different roadsurface materials can be tested. The structural design is reasonble and compact and use is convenient and flexible.

Description

technical field [0001] The invention relates to the technical field of automobile testing, in particular to a roller bracket for testing the off-road ability of automobiles to get out of trouble. Background technique [0002] With the continuous improvement of automobile technology, in automobile products, especially SUV / off-road vehicle products, various manufacturers continue to invest in new technologies and parts to improve the off-road capability of vehicles on non-paved roads or road conditions. What follows is that during the product development process, it is necessary to test the off-road capability of the vehicle in order to grasp the actual off-road performance of the developed product and market benchmark models. [0003] For the vehicle's ability to get out of trouble when off-road, the test specifications are the following three categories and five standard modes, such as Figure 8 shown. In addition, when the car is off-road on non-paved roads and roadless ro...
