Description

[Detailed description of the invention] This invention relates to an improvement of the front wheel suspension system already proposed by the applicant (please refer to the specification of Utility Model Application No. 1987-93690 if necessary), and the front and rear ends of the base of the lower arm are In a front wheel suspension system for an automobile, which is attached to a cross member via a rear arm bushing, and the cross member is attached to a body via a plurality of bushes, the rear arm bushing is clamped by the cross member and the clamp member. In addition, the outer cylinder of the rear bush among the plurality of bushes is fixed to the same clamp member, and its purpose is to make effective use of space. Another object of the present invention is to provide an improved front wheel suspension system for an automobile that allows easy assembly of rear bushings.

Next, the front wheel suspension system of the present invention will be explained with reference to an embodiment shown in FIGS. 1 to 5. 1 is an integrated cross member of the front wheel suspension system, 2 is a lower arm, and 3 is a rack and pinion gear of the front wheel steering system. , 4 is the steering joint, 5 is the front arm bushing, and the front arm bushing 5 is:
It is composed of a compression rod on the side of the cross member 1, an outer cylinder fixed to the front end of the base of the lower arm 2, and an elastic body such as synthetic rubber that is integrally assembled between these by press-fitting or the like. Further, 2a is a compression rod protruding rearward from the rear end of the base of the lower arm 2, 6 is a rear arm bushing integrally assembled into the compression rod 2a by press fitting, etc., and 10 is the same arm bushing. 6
A clamp member (plate member) for clamping the above-mentioned cross member 1 with the cross member 1, 11 is a clamp member mounting bolt for attaching the clamp member 10 to the cross member 1, a is a body frame, and b is a cross member on the side of the body frame a. , 7, 8, and 9 connect the cross member 1 on the front wheel suspension side to the same body frame a.
The bush 9 is attached to the cross member b on the side of the body frame a, and the bush 9 includes a bolt 9a fixed to the body frame a, an inner cylinder 9b fitted into the bolt 9a, an outer cylinder 9d, and the same inner and outer cylinders. 9
It is composed of an elastic body 9c made of synthetic rubber or the like that is integrally assembled between b and 9d by press-fitting or the like, and a nut 9e that fixes the inner cylinder 9b to the bolt 9a,
A clamp member 10 for clamping the arm bush 6 is welded and fixed to the outer cylinder 9d of the bush 9. Incidentally, the bushes 7 and 8 are also constructed almost in the same way as the bush 9, but a detailed explanation thereof will be omitted. Further, the lower arm 2 is elastically supported by arm bushes 5 and 6, and is swingable in the vertical direction about the arrow line in FIG.

The front wheel suspension system for an automobile according to the present invention is constructed by attaching the front and rear ends of the base of the lower arm 2 to the cross member 1 via the front and rear arm bushes 5 and 6 as described above, and attaching the cross member 1 to a plurality of bushes 7,
In the front wheel suspension system of an automobile, which is attached to the bodies a and b via 8 and 9, the rear arm bush 6
is clamped by the cross member 1 and the clamp member 10, and the outer cylinder 9d of the rear bush 9 among the plurality of bushes 7, 8, and 9 is fixed to the clamp member 10, so that the rear arm bush 6 and the rear The configuration around the side bush 9 is simplified, and the narrow space around it can be used effectively. Also, at the same time, each of the rear bushings 6 and 9,
Furthermore, the bushings 6 and 9 can be assembled by tightening the mounting bolts, making it easy to assemble the bushes 6 and 9.
