Background
With the rapid development of social economy, automobiles become indispensable vehicles for human beings, and the consumer groups for automobile maintenance of various brands and models are also increasingly huge. The automobile inspection technology is derived from automobile maintenance technology, and the automobile maintenance is developed along with the development of the automobile technology. The existing test bench for testing the four-wheel drive performance and the passing capacity of the automobile in the market is mostly made into a large platform steel frame, four wheels of the automobile are flatly attached to a platform road surface and are tested, a plurality of notches for suspending the wheels are formed in the platform, and when the four-wheel drive system is tested, the single wheel is suspended, so that the slipping and idling effect is created. However, the platform can not simulate the real road condition of traveling on a rugged road, and can not scratch the automobile chassis when the vehicle passes through, so that the production requirement of manufacturers is difficult to meet.

And the utility model discloses when letting the car go out the unsettled or unsettled gesture of unilateral rear wheel of unilateral front wheel and carry out the four-wheel drive system test, because of other three wheel is pressed on the ramp of the another side of unsettled direction, according to the whole focus of gravity principle car still fall on this one side ramp that three wheel pressed and pasted, so the car can not overturn to unsettled direction, has ensured the safety and the reliability of test. The utility model discloses can be used for testing the four-wheel drive system performance of car, can test the car again and vertically pass through the angle, on simple structure, operation safety and guaranteed the basis of test result degree of accuracy, make whole testing process easy and simple to handle again, can satisfy the production requirement of vast producer.
The present invention will be further described with reference to the accompanying drawings.
