トーシヨンビーム式リヤアクスルに関する。[Detailed Description of the Invention] The present invention relates to a torsion beam rear axle, and more particularly to a torsion beam rear axle in which axle spindle connecting plates are welded to both axial ends of an axle beam with an open cross section.

立懸架の如き相対運動を許容させるのである。 In general, this type of torsion beam rear axle has a connecting plate fixed by welding to both axial ends of an axle beam formed into a U-shaped cross section, and a flange is formed at the axial end of an axle spindle that supports the rear wheel. The spindle is bolted to the connecting plate through the flange, and when the car bounces or rebounds, the torsional action of the axle beam causes relative movement between the two rear wheels, similar to independent suspension. It is allowed.

には、前記アクスルビームにおける前記応力集中
部位が破壊する虞れがあつた。 By the way, as described above, when a torsional load acts on the axle beam and the beam deforms, the stress generated due to the deformation of the beam is applied to the welded portion of the axle beam with the connecting plate, and also to the open position of the beam. Since the action is concentrated on the opposing curved parts, the fatigue in this part is much larger than in other parts, and sometimes the welded part between the stress concentration part and the connecting plate in the axle beam is damaged, Alternatively, if the welding strength is high, there is a risk that the stress concentration area in the axle beam will break.
本考案はこのような実情に鑑みて考案したもの

リヤアクスルを提供せんとするにある。 The present invention was devised in view of the above circumstances, and the purpose is to create a torsion beam type rear axle that is free from the risk of damage to the welding between the axle beam and the connecting plate, or destruction of the axle beam. We are trying to provide the following.
以下本考案にかかるトーシヨンビーム式リヤア
クスルを図に示す実施例に従つて説明する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS A torsion beam type rear axle according to the present invention will be explained below according to an embodiment shown in the drawings.

固定されている。 Dambars 2, 2 that elastically support the vehicle body are attached to brackets 11, 11 provided on the upper surface near both axial ends of the axle beam 1, and dampers 2, 2, which will be described later, are attached to both ends of the axle beam 1. The connecting plates 3, 3 of the axle spindle are fixed by welding.

The beam 1 is notched in the shape of a gentle arc that gradually becomes shallower inward in the axial direction from both ends in the axial direction, and both ends in the axial direction of the beam 1 are formed into a bifurcated shape, and the notch The length l 1 is approximately the same length as the width interval l 2 of the beam 1.

Reinforcing members 5, 5 having a substantially inverted U-shaped cross section covering the upper part of the cutout portion S are attached by welding, and the end surfaces of the reinforcing members 5, 5 and the connecting plates 3, 3 are fixed by welding. There is.
尚、図中６はバツキングプレートを示す。 In addition, 6 in the figure shows a backing plate.

る応力集中が生じることがないのである。 The present invention has the above structure. For example, when a torsional load is applied to the axle beam 1 due to bounce or rebound of a car, the axle beam 1 deforms in response to the torsional load and reliably absorbs the torsional load. Relative motion is allowed between the wheels 40, 40 as in independent suspension, and the stress generated due to the deformation of the axle beam 1 is distributed and acts on both end portions of the beam 1, resulting in so-called stress concentration. There is no such thing.

ある。 As described above, in the present invention, since the axle beam is notched near the welded part with the connecting plate and opposite to the open position, even if the beam is deformed due to a torsional load acting on the axle beam, the beam The stress generated due to the deformation of the axle beam and the connecting plate can be reliably and satisfactorily absorbed while not acting concentratedly on both ends of the beam in the axial direction. There is no risk that the welded portion of the beam will be damaged or that the beam itself will be destroyed.
