Horizontal stabilizer bar assembly with quick and adjustable roll stiffness of FSAE racing car and adjusting method thereof

Abstract

The invention discloses a horizontal stabilizer bar assembly with quick and adjustable roll stiffness of an FSAE racing car and an adjusting method thereof. The horizontal stabilizer bar assembly withthe quick and adjustable roll stiffness of the FSAE racing car comprises a torsion bar spring, end heads, adjusting arms, pull rods, bushes, lifting lugs and lifting lug seats. The end heads are welded at the two ends of the torsion bar spring and connected with the pull rods through adjusting arms, the adjusting arms are provided with adjusting holes in a machining mode, and the torsion bar spring is arranged in lifting lug holes through the bushes, and the lifting lugs and the lifting lug seats are arranged by using saw teeth with the same parameters on the two bottom surfaces and clampinga pair of bolt nuts. The lifting lug seats are provided with guide slots in a machining mode, and the lengths of the guide slots are no less than the center distance of the farthest two adjusting holes on the adjusting arms. The horizontal stabilizer bar assembly with the quick and adjustable roll stiffness of the FSAE racing car and the adjusting method thereof can realize big and small step lengths adjusting method. The horizontal stabilizer bar assembly with the quick and adjustable roll stiffness of the FSAE racing car and the adjusting method thereof greatly solve the problem that an common horizontal stabilizer bar adjusting structure is heavy, tools needed to be used during adjusting is more, parts to be assembled are more, the use ratio of adjusting slots is low, and both sides ofthe lifting lug holes are not prone to ensuring coaxial.

Description

technical field [0001] The invention belongs to the technical field of vehicle suspensions, and in particular relates to a stabilizer bar assembly and an adjusting method thereof with which the roll stiffness of an FSAE racing car can be quickly adjusted. Background technique [0002] The function of the FSAE racing car’s stabilizer bar is to adjust the rolling stiffness of the car’s suspension. On the one hand, it reduces the body roll when the car is cornering. The explanation of the need to adjust the suspension roll stiffness of the racing car is as follows. Due to the errors in the design, processing, and assembly of the racing car, after the assembly of the racing car is completed, the suspension roll stiffness and the steering characteristics of the racing car cannot reach the best state. The requirements for roll stiffness and steering characteristics of racing car suspension are different, so it is necessary to make the anti-roll bar assembly have the function of fa...

Problems solved by technology

[0003] Chinese Invention Patent Application Publication No. CN 106853753 A discloses a stabilizer bar mechanism with adjustable stiffness for FSAE racing cars. This invention realizes stiffness adjustment by moving the horizontal stabilizer bar, which improves the current stiffness adjustment when swinging the tie rod, which causes the tie rod to be stressed. average problem

However, the stabilizer bar mechanism has the following problems: (1) The bearing seat is too large in size and mass; (2) The single bearing seat is fixed with double bolts, and the utilization rate of the guide groove is low, thereby increasing the length and mass of the main plate , (3) The single bearing seat is fixed with double nuts, there are many disassembly and assembly procedures, and the adjustment efficiency is low. (4) The bearing seats on both sides can slide on the main body plate, and the coaxiality of the bearing seats on both sides cannot be guaranteed during installation

However, it does not involve the design of the specific stabilizer bar adjustment mechanism, and fails to solve the above problems
