Abstract

PURPOSE:To contrive an improvement in stability of operation, by a method wherein an arm provided with an axle is turned inward centering around a supporting part and a wheel is made to displace angularly in the direction of toe- in, when side force is applied to the wheel at the time of turning of a vehicle. CONSTITUTION:A front end part of a suspension arm 2 is fixed to a supporting component 1 on a vehicular body rockably through a pivot 3. The rear of an arm 8 having an axle 6 is fixed to the rear of the suspension arm 2 rockably through a vertical shaft 5, and the front of the arm 8 is fixed to a bracket 9 provided on the suspension arm 2 with a bolt 11 and washer 12 through elastic bodies 10, 10' so that the arm 8 is difficult to displace in the vertical direction and is displacable around the vertical shaft 5. With this construction, when side force F is applied to a wheel 7 at the time of turning of a vehicle, stability of operation can be improved as the arm 8 is turned inwardly centering around the vertical shaft 5 while the elastic bodies 10, 10' is being deformed by the arm 8 and the wheel 7 is made to displace angularly in the direction of toe-in.

なる等の不具合を有している。The above-mentioned trailing arm type suspension system has a bushing made of an elastic material such as rubber interposed in the attachment part of the suspension arm to the vehicle body to absorb and reduce the transmission of vibrations from the wheel side to the vehicle body. Therefore, when a side force is applied to the wheel (outer wheel side) when turning, etc., the bushing bends and the wheel is angularly displaced in the toe-out direction, which worsens the steering stability.This problem is solved. Therefore, in a type of suspension arm that uses a two-pronged link, the link arm closer to the wheel is made of a leaf spring, and when a side force is applied to the wheel during turning, the link arm made of the leaf spring is A wheel that deflects inward to displace the wheel in the toe-in direction has been developed (see Japanese Patent Publication No. 52-34288), but if the suspension arm itself is made of a leaf spring as described above, the leaf spring will not respond to the side force. It is difficult to set the amount of deflection of the wheel, which results in problems such as unstable wheel support.

るものである。Compared to the elastic body 10.1σ, it is made thinner as shown in the figure so that it is considerably harder against loads in the left and right directions and less elastic deformation occurs, and side force F acts on the wheel T when turning. Then, the inner elastic body 10 of the front support part is greatly compressed and deformed with respect to the inner elastic body 13 of the rear support part of the arm 8, the arm 8 rotates inward about the rear support part, and the wheel γ moves in the toe-in direction. As described above, according to the present invention, the rear part of the arm, which receives the axle that supports the wheel in the middle part, is at the rear part of the suspension arm, so that it can be angularly displaced. The front part of the arm is attached to the suspension arm via an elastic body so that it cannot be displaced in the vertical direction, but can be displaced in the left and right direction within the range of deformation of the elastic body. With this structure, when a side force is applied to the wheel such as when the vehicle turns, the arm elastically deforms the elastic body of the front support part and rotates inward around the rear support part to move the wheel in the toe-in direction. The angular displacement is aimed at significantly improving steering stability, and the number of component parts is small. The amount of angular displacement in the toe-in direction against the side force is determined by the elastic deformation characteristics of the elastic body interposed in the front support part of the arm. This can be easily carried out by appropriately selecting the wheels, and stable wheel support can be ensured. Combined with the low cost, this can bring about great practical effects.
