A stabilizer bar system for Formula Student racing car

Abstract

The invention provides a stabilizer bar system for a Formula SAE race car. The stabilizer bar system comprises bar end bearings (1), M6 nuts (2), tie bars (3), adjusting arms (4), bolts (5), clampingsleeves (6) , upper fixing lugs (7), a torsion bar (8) and shaft circlips (9). The stabilizer bar system adds detachable copper sleeves between the torsion bar and the fixing lugs of a stabilizer barto reduce the friction resistance of the stabilizer bar system, and realizes the necessary replacement according to the wear condition of the copper sleeves so as to ensure the consistency of actual parameters with design parameters of the stabilizer bar system as much as possible; and at the same time, by optimizing the structure of the upper fixing lugs (7) and decreasing the cantilever length of the torsion bar (8), the stabilizer bar system reduces the influence on the roll stiffness provided by the stabilizer bar system due to the bending deformation of the torsion bar (8).

Description

technical field [0001] The invention relates to a racing car operating technology, in particular to a lateral stabilizer bar system and an operating method for a student formula racing car. Background technique [0002] The roll angle stiffness of the suspension is one of the main factors affecting the static roll stability of the vehicle, and it will also directly affect the steering characteristics of the vehicle. In the FSAE Formula Student racing car, in order to increase the roll angle stiffness of the suspension, most cars are equipped with a stabilizer bar device. The disadvantage of the stabilizer bar used by most teams in the Chinese race is: the bolt connection between the adjustment arm and the torsion bar cannot completely restrain the relative rotation of the two, thus affecting the roll stiffness provided by the stabilizer bar; the adjustment arm adopts a straight arm The structure occupies a large space and limits the expansion of the adjustment range; the to...
