Torsion beam with adjustable rear axle stiffness

Abstract

The invention provides a torsion beam with adjustable rear axle stiffness. The torsion beam with the adjustable rear axle stiffness structurally comprises a left trailing arm, a right trailing arm and a torsion beam body, wherein the left trailing arm and the right trailing arm are symmetrically arranged on two sides, namely the left side and the right side, of a vehicle and extend along the length direction of the vehicle, the torsion beam body extends along the width direction of the vehicle, and two ends of the torsion beam body are connected with the left trailing arm and the right trailing arm. The torsion beam with the adjustable rear axle stiffness is characterized in that a left fixing rod is arranged on the inner side of the left trailing arm, a right fixing rod is arranged on the inner side of the right trailing arm, the left fixing rod and the right fixing rod are arranged in an opposite mode, a stabilizer bar is arranged between the left fixing rod and the right fixing rod, and two ends of the stabilizer bar are in rigid connection with the suspension end of the left fixing rod and the suspension end of the right fixing rod in a detachable mode. According to the torsion beam with the adjustable rear axle stiffness, the stabilizer bar which can be replaced is additionally arranged on a rear axle, a user just needs to replace different stabilizers to change the stiffness of the torsion beam, and therefore the manufacturing cycle of a torsion beam rear axle spare part for adjustment is shortened, manufacturing fees are saved, replacing times of the torsion beam rear axle in an adjusting process are reduced, and work efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of automobile suspension systems, in particular to a torsion beam with adjustable rear axle stiffness. Background technique [0002] At present, there is no quick and easy way to change the stiffness of the torsion beam when adjusting the stiffness of the rear axle of the torsion beam. The existing problems: [0003] When adjusting the stiffness of the torsion beam, the stiffness of the torsion beam is judged through subjective evaluation, and then the production, replacement and loading of the rear axle of the new torsion beam are completed through trial production. The adjustment of the stiffness of the torsion beam is performed again, and so on. Due to the long production cycle of the torsion beam, this approach will inevitably lead to a longer adjustment cycle. [0004] Before adjusting the stiffness of the torsion beam, sometimes multiple torsion beams of different stiffness are made at one time, and the samp...
