Abstract

PURPOSE:To enhance the flexibility and rigidity of a suspension, by providing such an arrangement that the inner end of second arm section of a lower control arm is journalled to a subframe which extends widthwise of a vehicle and which is attached to a vehicle body through the intermediary of a resilient member at the position that is different from the journalled position of the second arm section in the vertical direction. CONSTITUTION:When rearward force acts on a subframe 10 from a lower control arm 4 in the longitudinal direction during braking, the subframe 10 swings rearward while it deforms a resilient member 11 since the fulcrum of the subframe 10 on a vehicle body 10 is higher than the fulcrum of second arm 6 of the lower control arm 4 on the subframe 10, and therefore, the lower control arm 4 may be displaced rearward to ensure compliance. With this arrangement, it is possible to enhance the flexibility and rigidity of the suspension.

A hub carrier that rotatably supports a wheel is swingably supported by a lower control arm that extends in the width direction of the vehicle and has a second arm portion whose inner end is supported by the vehicle body via an elastic pusher. 0 Regarding Suspended Rear Suspension (2) Conventional Technology Cacarlya suspension is one of the attractive structures in terms of space efficiency, but on the other hand, it has a pushing effect when sufficient compliance is required. Difficult issues arise in terms of power. In other words, in the force that acts in the longitudinal direction of the vehicle, moment and shear force act as pushes, so it is difficult to ensure compliance unless each push is made flexible. However, if the push is made flexible, the lateral stiffness and toe stiffness decrease, which is not desirable. Therefore, as disclosed in U.S. Pat. No. 4,157,840, a device in which the second arm portion is formed of a leaf spring to separate the force has been proposed.
