Torsion beam axle device for vehicle

Abstract

A torsion beam axle device for a vehicle may include: a pair of trailing arm members having wheels coupled thereto and rotatably coupled to a vehicle body; and a torsion beam member having both ends coupled to the trailing arm member, and bent in a shape protruding toward a rear side of the vehicle body.

Description

technical field [0001] The present invention relates to a torsion beam axle device for a vehicle. More specifically, the torsion beam axle device for a vehicle secures a space between wheels, thereby ensuring a loading space and an installation space for peripheral components, etc., and strengthens lateral rigidity. Background technique [0002] Generally speaking, CTBA (Coupled Torsion Beam Axle, coupled torsion beam axle) is a type of torsion beam axle (Torsion Beam Axle), also known as torsion beam suspension (Twisted Beam Suspension), also known as coupling (Coupled Link ). [0003] CTBA has trailing arm parts on both sides of the torsion beam part, one end of the trailing arm part is combined with an installation bush for mounting on the vehicle body, and the other end of the trailing arm has a structure for engaging the spring seat part, and the spring seat It is to install the spindle bracket and the body spring. [0004] Generally speaking, the torsion beam part su...

AI Technical Summary

Problems solved by technology

[0004] Generally speaking, the torsion beam portion suitable for vehicles is approximately linear, and it is located on the line connecting the center of the wheel, or it is located in front of the line connecting the center of the wheel, so there is a possibility of reducing the loading space or reducing the installation of peripheral parts. space problem

[0005] In addition, the conventional torsion beam axle device for vehicles lacks resistance rigidity against the lateral force applied to the wheels, that is, lacks lateral rigidity, and suffers from poor steering performance and ride quality.
