Abstract

PURPOSE:To maximize the allowance of the position control of a wheel by setting a specific direction of an axis for a control rod in a semi-trailing type suspension. CONSTITUTION:A carrier 4 is pivotted on a semi-trailing arm 2 by a pin 14, while a control rod 8 is pivotted on a side shaft 18 of the carrier 4. At this stage, the cross point of shaft lines 20 and 22 of the pin 14 and the control rod 8 is located behind and outside a wheel center 24. Thereby, when a side force (fc) or a braking force (fb) is added, an imaginary rotational center of a wheel 5 is set off behind the wheel center 24, and consequently, a toe-in change can be given to the wheel 6.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a swing axle five-type suspension system, in which the rear suspension system for automobiles has been conventionally known as a rear suspension system. A semi-trailing Type 5 is known, which is intermediate between the Type 5 and the Type 5.

This is an independent suspension that is often used in I-T cars. In addition, the semi-trailing arm type rear suspension has a low unsprung weight, a large anti-dive effect, a large degree of design freedom in terms of maneuverability and stability, and the differential shaft does not swing. It also has the advantage of being able to lower the floor. However, this suspension system also has the disadvantage that it tends to run out due to lateral force when turning and braking force when braking. In order to further increase maneuverability and stability, there is a need to increase the degree of freedom in wheel attitude control, such as toe-in displacement due to lateral force and braking force, and subtle canno 4 changes during bumps. With trailing arms, there is a limit to the degree of freedom in controlling the attitude of the wheels.

As an improvement to increase the degree of freedom Kp in controlling the wheel posture of the above-mentioned conventional semi-trailing arm 5-type rear suspension, a carrier that supports the wheel rotatably, and an upper carrier that is pivotally connected to the vehicle body at the base and pivoted at the end. The U.S. patent discloses a semi-trailing arm that attaches to the vehicle body, a spring attached to the vehicle body and the other end attached to the upper P semi-trailing arm, and a differential gear and the above-mentioned carrier connected by a long drive shaft. ? , 2ll&? /
It is proposed by No. 7. This suspension has the advantage of having a large degree of freedom in controlling the attitude of the wheels, but it does not allow the use of a Misaki joint on the drive shaft.
Furthermore, it has the disadvantage that it cannot be applied to front-wheel drive vehicles. Also,
This suspension system sometimes does not provide toe-in effect when turning or braking, which affects maneuverability and stability.

As mentioned above, since the axis 20 of the control rod 8 and the axis 22 of the pin 14 intersect at the rear and outside of the wheel center 24 on the horizontal projection plane, this '&A can be the virtual center of rotation. If the bucket car acts on the wheel center E, the virtual (b) center of motion of the wheel 5 is offset rearward from the wheel center 24, so the predisposition of the wheel 6 becomes inward. It is possible to cause a toe-in change. Furthermore, when the braking force f is applied to the wheel center 24, the virtual center of rotation of the wheel 6 is offset outward from the wheel center 24, so that
It is possible to cause a toe-in change in which the front portion of the wheel 6 changes inward. Furthermore, since the front part of the trailing arm 2 is supported by a rubber bushing, it tends to be weak against lateral forces, but it can be tensioned by control rods 8 installed in the left and right directions of the vehicle, so it is resistant to lateral forces. Swing hard. Although the above embodiment is a rear wheel drive vehicle, the present invention can of course be applied to a rear suspension of a front wheel drive vehicle.
