Abstract

PURPOSE:To contrive an improvement of stability in running performance, by a method wherein a rotating center of a frame component to which a trailing arm is installed is made more outer than a wheel, and a variation of toe-in is made to generate on the wheel by front and rear forces of the wheel. CONSTITUTION:A trailing arm 1 supporting a wheel 2 is installed on a frame component 4. The external edge 0 of the frame component 4 is made into a rotating center, and an internal side is fixed easily and variably to a subframe 5. The rotating center O of the frame component 4 is made more outer than a ground center P. With this, a variation of a toe-in on a wheel is generated and stability in running performance is improved when front and rear forces F act on the wheel 2.

However, in conventional trail link arm type suspensions, for example, as shown in Japanese Patent Application Laid-open Sho Guar Ro7, one end of the trailing arm rotatably supports the wheel, and the other end of the trailing arm is elastically supported by the vehicle body. A rubber push-up seat is attached to the sub-frame with a pivot in the left and right direction.
Since the wheel is rotatably pivoted through the wheel, if a force in the longitudinal direction, that is, a longitudinal force is applied to the wheel, the wheel will undergo toe-out change due to deformation of the rubber push-sea, which is unfavorable in terms of driving stability. Ta.

The misfire revolving was created in view of this point, and due to the action of longitudinal force on the wheel, the wheel does not tend to change toe-out, but tends to change in toe-in,
The main purpose is to provide a 4'M tray link arm type suspension with improved running stability.

On the other hand, the frame member 4 is attached to the vehicle body (pin members 7, 8) via lanomer knobs 9 and 10 at both ends, and the laminar knobs 9 on the outer side of the vehicle body are attached to the ground contact center of the wheel 2. Since the rubber push-piece 10 located on the outer side of the vehicle body than P is easily deformed in the longitudinal direction due to the space 10a, the longitudinal force F acts on the wheel 2, and the longitudinal force F acts on the wheel 2. Trailing arm 1
When transmitted to the frame member 4 via the frame member 4, the frame member 4 will largely rotate counterclockwise about the central axis O (rotation axis) of the pin member 7.

In the above embodiment, this rubber push-piece 10 has a space 10a in the front part, but this is because the pin member 7 is fixedly installed on the vehicle body (subframe 5) side. In other words, it is preferable that a space be provided in the rear part of the rubber push-piece 9 in order to facilitate the rotational displacement of the frame member 4 in the case where the rotation shaft is fixed to the frame member 4 side. Furthermore, although the above embodiment relates to a semi-trailing type suspension, the present invention can also be applied to a full trailing arm type suspension.
