Abstract

PURPOSE:To improve a degree of durability in an elastic bush so better, by setting each of body-side fulcrum axes of an A arm and a lateral rod to a side-view parallelism, in case of a device which supports a rear axle with at least each piece of the A arm and the lateral rod. CONSTITUTION:A bracket 11 is tightly attached to a lower part of a strut 10 whose one end is supported on an axle housing 7 supporting a rear axle 5 free of rotation, via a bracket 9, and a free end part of and A arm 12 is connected to a front end of this bracket 11 via a all joint 16. A fulcrum shaft 14 supporting both leg ends 12a of the A arm 12 via an elastic bush is attached to a support member 1 of a rear suspension via a bracket 15. In addition, an interval between the bracket 11 and the support member 1 is connected via a lateral rod 18. At the abovementioned, a body-side fulcrum axis l1 of the A arm 12 and a body-side fulcrum axis of the lateral rod are set to a side-view parallelism.

There is one shown in Figure 4 of No. 6, but it is expensive because it uses a ball joint to attach the lateral rod to the vehicle body. Therefore, when a relatively inexpensive bushing is used, the pivot portion of the A-arm and the lateral rod on the vehicle body side is usually constructed as shown in FIG. In the figure, a is the A-arm, b and b are its body side pivot parts, Il is the pivot axis connecting the centers of the pivot parts and b, C is the free end of the A-arm, and arrow B is its swing. It is the direction. Also, d is the lateral rod, e is its pivot point on the vehicle body side, 1! is the pivot axis of the pivot e, f is the free end of the lateral rod d, and arrow C is its swing direction.

性が低下するという問題点があった。(Problems to be Solved by the Invention) However, in the conventional device shown in FIG. 5 described above, the pivot axis 2. is slightly inclined, but since the pivot axis 18 is horizontal, the swinging direction of the free end C of the A-arm a (arrow B) and the swinging direction of the free end f of the lateral rod d (arrow C) are not parallel, so when the rear wheels bounce or rebound, the elastic bushings in the pivot parts and e on each side of the vehicle become distorted, making it difficult to ensure rigidity and reducing durability. There was a problem.

を解決することを目的としている。The present invention has been made with attention to such conventional problems, and the axis of the bushing shaft of the vehicle body side pivot portion of the lateral rod is set in side view with respect to the axis of the vehicle body side pivot shaft of the A-arm. The purpose is to solve the above problem by setting them in parallel.

する。(Means for solving the problem) In order to achieve the above-mentioned object, in the present invention, in a rear suspension that supports the rear axle by at least one A-arm and one lateral rod, the A-arm is mounted on the vehicle body side. The rear suspension is constructed by setting the pivot axis and the vehicle body side pivot axis of the lateral rod parallel to each other in a side view.
