摘要： In a multi-link rear suspension (A) in which a wheel support (11) is connected to a vehicle body through five links (6-10) and vehicle body side ends of the links are provided with rubber bushes (26), respectively, the lower end of a damping device (14) formed by coaxially arranging a coil spring (12) and a damper (13) is pivoted to a portion of the wheel support (11) located toward the inside of the vehicle body so that the vertical reaction force of the damping device (14) produces a moment Mn toward negative camber on a rear wheel (2). The moment Mn is set to be always larger than a moment Mp toward positive camber produced by a side force on the outside rear wheel (2) during vehicle cornering until limit maneuvering conditions of the outside rear wheel due to the side force are reached. The damping device (14) is disposed with respect to a suppositive king pin axle K so that the vertical reaction force thereof produces a moment toward toe-in on the rear wheel (2). In this manner, the multi-link suspension provides a sharp driving feeling applicable even for a sports car while maintaining a good ride through the involvement of the rubber bushes (26).

摘要： A suspension system for a vehicle includes a suspension arm. The outer end portion of the suspension arm is connected to a wheel support for rotatably supporting a wheel. The inner end portion of the suspension arm is bifurcated and has first and second branch arms spaced from each other in the longitudinal direction of the vehicle body. Each of the inner end portions of the first and second branch arms is supported by a slide member so that the inner end portion is slidable relative to the vehicle body in the longitudinal direction of the same. A coil spring is provided for at least one of the first and second branch arms and urges forward the suspension arm. A stopper defines the foremost position of the suspension arm which is urged forward by said coil spring.

摘要： An automobile sub-frame structure for supporting two double wishbone type rear suspensions on its respective sides includes a pair of juxtaposed first members extending in a direction widthwise of a vehicle body, a pair of opposed second members extending substantially vertically and each rigidly secured at an upper portion thereof to one end of each first member, and a pair of third members rigidly secured to lower portions of the second members and to a lower surface of a central portion of each first member. In the sub-frame structure, a plurality of truss structures are formed by the first, second and third members so that the sub-frame structure will be sufficiently rigid. Each double wishbone type rear suspension includes upper and lower control arms for pivotably supporting a rear wheel, which control arms are pivotably connected at their inner ends to the second members in the vicinity of portions connecting the first and second members and in the vicinity of portions connecting the second and third members, respectively.

摘要： An automotive vehicle is provided with two rear suspension units for pivotably supporting respective rear wheels. Each rear suspension unit includes a wheel support for pivotably supporting one the rear wheels, an H-shaped lower control arm pivotably connected to the wheel support, an A-shaped upper control arm pivotably connected to the wheel support, and a damper unit pivotably connected at its lower end portion with either the wheel support or the lower control arm. The damper unit is disposed behind the upper control arm in a extending longitudinally of the vehicle body. The connecting portion at which the upper control arm and the wheel support are connected is located in front of the center of the rear wheel. Accordingly, an imaginary king pin axis is relatively largely inclined, which axis connects an outer rear end portion of the lower control arm and the connecting portion at which the upper control arm and the wheel support are connected. Such being the structure making up the rear suspension unit, the rear wheels are readily movable in a direction of toe-in, when a lateral force acts upon the rear wheels.
