Problems solved by technology

Conventionally, torsion beams are manufactured from steel pipes whose circumference is constant over the entire length by press forming, etc. However, since the circumference is assumed to be constant, even if it is necessary to achieve appropriate torsional rigidity by changing the cross-sectional shape And to ensure the bending strength, its effect is naturally limited

Embodiment Construction

[0058] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following description of a preferred embodiment is merely an example in nature and is not intended to limit the invention, its object of application or its use.

[0059]

[0060] figure 1 The vehicle torsion beam type rear suspension shown in (top view) includes: swing arms 1 on the left and right sides of the vehicle body supporting the wheels; Torsion beam 2.

[0061] The swing arm 1 is configured such that a pivot support portion at its front end is pivotally supported by a joint 3 on a rear side member of a vehicle body, and a rear end portion thereof swings up and down relative to the vehicle body. Wherein, the joint 3 is composed of a pivot and a rubber bush. A bracket 4 serving as a wheel mounting portion is provided at a rear end portion of the swing arm 1 . The bracket 4 supports the wheel to rotate freely, and the wheel is driven to rotate by the drive...

Abstract

The present invention discloses a vehicle torsion beam suspension and a vehicle torsion beam. The torsion beam (2) of a vehicle torsion beam suspension has a closed cross section. A beam center portion (21) has an inverse substantially v-shaped cross section or a substantially v-shaped cross section. Circumference increasing portions (22) having a longer circumferential length toward the beam endsare disposed at opposite sides of the beam center portion. Each circumference increasing portion (22) has a beam width that is a width in the fore and aft direction of a vehicle body, the beam widthgradually increasing toward a beam end, and increasing at a higher rate as a position of the beam width is closer to the beam end.

Description

technical field [0001] The invention relates to a torsion beam type suspension for vehicles and a torsion beam for vehicles. Background technique [0002] Patent Document 1 and Patent Document 2 disclose a torsion beam type suspension, which is one type of vehicle suspension. This suspension includes trailing arms on left and right sides of a vehicle body that support wheels, and a torsion beam that connects the two trailing arms. The base end portion of the swing arm is rotatably coupled to the vehicle body, and the wheel is rotatably attached to the top end portion of the swing arm. The ends of the torsion beams are combined with the swing arms. The spring seat is combined with the end of the torsion beam and the swing arm, and a coil spring is arranged between the spring seat and the vehicle body. [0003] The torsion beam needs to have appropriate torsional rigidity from the viewpoint of controlling the shape when the vehicle rolls, and the like. On the other hand, s...
