Abstract: Vehicle body structure includes: a sub frame mounted to a vehicle body frame via elastic members and having at least one of suspensions and a power source supported thereon; a collision detecting sensor; and load transmitting connection mechanisms for connecting the sub frame to the vehicle body frame once the collision detecting sensor detects a collision of the vehicle. Load transmission characteristic provided between the vehicle body frame and the sub frame by the load transmitting connection mechanism is greater than a load transmission characteristic provided by the elastic bushes.

Abstract: A vehicular suspension system is provided which includes upper and lower arms connected to a vehicle body in such a manner as to pivot in an up-and-down direction. The upper arm and the lower arm retain upper and lower portions of a knuckle, respectively. The suspension system includes retention mechanisms for retaining the upper and lower arms in such a manner as to allow the upper and lower arms to shift in a lateral direction of the vehicle body, and conversion mechanisms for converting pivotal movements of the upper and lower arms in the up-and-down direction into displacements of the upper and lower arms in the lateral direction of the vehicle body.

Abstract: A process for producing a suspension member for a vehicle, which member comprises a first mounting portion relatively swingably connected to either one of a vehicle body and an axle, through a connecting member, an a second mounting portion integrally connected to the first mounting portion and connected to the other of the vehicle body and the axle. The first mounting portion is provided at an outer surface thereof with a pair of parallel cam guides of readjusting the relative mounting position between the first mounting portion and a connection member by cooperation with eccentric cams connected to the connecting member. The process comprises steps of forming a base material for the suspension member by an extrusion, and cutting the base material along planes spaced at an equal distance form onto another in an extruding direction to provide a plurality of the suspension members.

Abstract: An upper arm 1 of a front suspention made of light alloy is provided with a lateral rubber bush mounting bore 2 connected to a vehicle body, and a vertical joint mounting bore 6 connected to a wheel support member. When forming the arm 1, a shape of the arm 1 is first determined such that the mounting bores 2 and 6 are directed in the same direction. Then, the arm 1 is extuded in an axial direction of the bores, and after cutting off the extruded material at a predetermined length, a portion of the mounting bore 2 is twisted by 90.degree.. Therefore, the extrusion can be employed for producing the suspention arm made of light alloy without increasing a thickness thereof.

Abstract: A suspension arm is formed of at least two arm bodies formed by an extrusion. The arm bodies are coupled such that their extruding directions intersect each other. The coupled assembly is integrally provided at one end thereof with a mounting portion for mounting to a wheel and at the other end of the coupled assembly with a mounting portion for mounting to the vehicle body. Thus, a required rigidity and strength can be efficiently provided to portions of the suspension arm to oppose various external forces applied to such portions, while enabling a reduction in weight of the suspension arm.

Abstract: A suspension system on a motor vehicle includes a transverse leaf spring interconnecting knuckles on which road wheels are rotatably supported. The suspension system includes a pair of knuckle members on which the road wheels are rotatably mounted, an elongate leaf spring which is vertically resilient and extends transversely with respect to the vehicle body, the leaf spring having opposite ends coupled to the knuckle members, respectively, a support member supporting the leaf spring at two supporting points thereon which are spaced from each other transversely with respect to the vehicle body, for allowing the leaf spring to move transversely but limiting the leaf spring against vertical movement with respect to the vehicle body, and a transverse movement limiting mechanism for allowing the leaf spring to move vertically but limiting the leaf spring against transverse movement with respect to the vehicle body.
