Spindle bracket of torsion beam axle suspension

Abstract

A spindle bracket of a torsion beam axle suspension system is defined on an end portion of a trailing arm to be connected to a hub assembly on which a wheel and a tire are mounted. The spindle bracket may include a first inner bracket that is welded to an inner side and an outer side of an end portion of a upper member of the trailing arm, a second inner bracket that is welded to an inner side and an outer side of an end portion of a lower member of the trailing arm, and an outer bracket that is attached to the first and second inner brackets to be engaged with the hub assembly in company with the first and second inner brackets.

Description

[0001] Cross References to Related Applications [0001] This application claims priority from Korean Patent Application No. 10-2008-0073236 filed on Jul. 25, 2008, the entirety of which is hereby incorporated by reference for all purposes. technical field [0002] The invention relates to a torsion beam suspension system. More particularly, the present invention relates to a axle frame of a torsion beam suspension system in which the welding length of the trailing arm is increased. Background technique [0003] In general, although the torsion beam suspension system has simple components and limited performance in terms of design, it has high driving stability compared with low production cost and light weight, so that it can be mainly used in small cars and medium-sized cars. [0004] Such as Image 6 As shown, in the torsion beam suspension system, the torsion beam 101 is arranged in the horizontal direction of the vehicle body, and the trailing arms 105 installed toget...

Problems solved by technology

[0009] However, if Figure 8 As shown, in the axle frame 103 of the torsion beam suspension system according to the conventional art, the welded portion ("A") is formed along the end circumference on the outer surface of the trailing arm 105, so that it cannot be formed in the trailing arm 105. Sufficient welding length is achieved and the durability of the welded part is weakened

[0010] In order to avoid the above-mentioned problems, in the conventional technology, the rigidity of the axle frame 103 is strengthened by increasing the size of the axle frame 103, thereby increasing the weight of the entire suspension system
