Anti-rollover device used for commercial vehicle high-speed travelling control performance test

Abstract

The invention relates to an anti-rollover device used for a commercial vehicle high-speed travelling control performance test. The device comprises a riding bolt (1), square steel tubes (2), U-shaped steels (3), a reinforced plate (4), wheel axles (5) and wheel assemblies (6), wherein the outer frame of a support frame is of a isosceles trapezoid which is formed by connecting the two upper and lower square steel tubes (2) of different lengths and the web edge U-shaped steels (3) which are in bilateral symmetry through bolts; the two wheel axles (5) are respectively arranged at the outer sides of the lower sections of the two U-shaped steels (3); and the two wheel assemblies (6) are respectively arranged on flange plate faces of the wheel axles (5) through bolts. The device is simple in structure, can be conveniently used under the condition of not changing the structure of a test vehicle, can be fixedly arranged on a frame rail through the riding bolt by reasonably utilizing the structure characteristics of the vehicle rail and is reliable in structure. The device can be used for effectively protecting the safety of the test vehicle and personnel when a high-risk test is carried out.

Description

technical field [0001] The invention relates to an automobile test auxiliary device, in particular to an anti-rollover device used for a high-speed driving control performance test of a commercial vehicle. Background technique [0002] At present, my country's automobile test standards are becoming more and more stringent, more and more items are required for mandatory tests, and the risk level of various tests is also getting higher and higher, especially in the handling performance test under the condition of high-speed driving of the vehicle, ABS's Road adhesion tests, double-shift curve tests, etc. are particularly prone to accidents such as vehicle rollover or even rollover, and even cause car crashes and fatalities. [0003] According to the research, when the vehicle is turning, the centrifugal force will cause the vehicle to roll. Under normal circumstances, the roll damping system composed of shock absorbers, stabilizer bars, rubber bushings, etc. has been considered...

[0002] At present, my country's automobile test standards are becoming more and more stringent, more and more items are required for mandatory tests, and the risk level of various tests is also getting higher and higher, especially in the handling performance test under the condition of high-speed driving of the vehicle, ABS's Road adhesion test, double-shift curve test, etc. are particularly prone to accidents such as vehicle rollover or even rollover, which may even cause car crashes and fatalities.

[0003] According to the research, when the vehicle is turning, the centrifugal force will cause the vehicle to roll. 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. The test vehicle is given a certain elastic restoring moment to restore it to its original state. However, when the vehicle undergoes a high-risk test, the vehicle speed will be too fast, the steering action will be too sharp, or the grip performance of one side tire will deteriorate, and the vehicle's roll moment will be greater than the elastic recovery moment of its own roll damping system. will inevitably roll over
