In the college equation series events, all the fleets adopt independent suspensions, and in order to ensure the operation stability of the whole vehicle, each fleet is provided with an anti-roll rod for a suspension system. On the competition field of the equations of college students in China, many motorcades adopt Z-shaped anti-roll bars, and rocker arms or shock absorbers of left and right suspensions are connected through the anti-roll bars made of two spring steels, so that the effect of stabilizing the car body is achieved.
However, in the actual process of machining and assembling, because of unavoidable machining errors and assembling errors, the situation that the assembling is difficult or even impossible often occurs; in addition, due to the influence of ground conditions, vehicle loads and other factors, the rigidity of the traditional anti-roll bar is determined during processing and assembling, so that the requirements under all working conditions cannot be met; if the anti-roll bar can not meet the driving condition of the racing car, the anti-roll bar must be replaced, which greatly increases the workload and the competition period, and can not be realized on the racing field.
Based on the defects, the Z-shaped variable-rigidity anti-roll rod structure provided by the application is mainly characterized in that the distance adjusting
