Anti-rollover device used for high-speed driving maneuverability test and anti-locking test for car

Abstract

The present invention involves the anti -rolling test of the high -speed driving of the car and the anti -hugging test.This device includes two parallel beams. The middle part of each beam is equipped with two fixed sleeves. Each fixed sleeve is equipped with a installation bolt.One end of the root beam is connected to the two ends of the V -shaped frame, and the other end is connected to the two ends of the other V -shaped frame, and the outer V -shaped frame is upward, so that the V -shaped frame and the beams form a angle; both ends are ends.The support board is connected to the outside of the bending of the V -shaped frame. The bottom of each support plate is installed with a universal ball through the supporting bolt.The structure of the present invention is simple. It can be easily used without changing the structure of the test vehicle, and it is convenient to disassemble. It is good for the ground with the tires as auxiliary tires and has good stability.The present invention can effectively protect the safety of test vehicles and personnel when conducting high -risk tests.

Problems solved by technology

[0002] At present, my country's automobile test standards are becoming more and more stringent, and more and more items are required for mandatory tests. Adhesion tests are particularly prone to accidents such as vehicle rollover or rollover, and even serious car crashes and fatalities

[0003] Under normal circumstances, the roll damping system composed of shock absorbers, stabilizer bars, rubber bushings, etc. has been considered in the design of various vehicles to give the test vehicle a certain elastic recovery moment to restore it to its original state, but this system generally only considers the vehicle Moment balance under normal driving conditions

However, when the vehicle used for a certain test project undertakes some limit test tasks, due to the excessive speed, excessive steering action or poor grip performance of one side tire, the rolling moment of the vehicle is greater than its own rolling damping coefficient. When the elastic restoring moment of , the vehicle will inevitably roll or roll over

At present, when carrying out such high-risk tests, various automobile manufacturers often adopt the method of reducing vehicle speed to avoid rollover or rollover, but in doing so, relevant test data cannot be obtained, which has brought a negative impact on the development of the whole vehicle.
