A vehicle body structure includes: a pair of left and right suspensions provided below a vehicle body floor; suspension mounting portions for mounting the suspensions to the vehicle body floor; a power supply device that supplies power to drive a vehicle; a frame that supports the power supply device; and frame mounting portions for mounting the frame to the vehicle body floor, wherein the frame mounting portions are disposed at positions overlapping in a vertical direction with the suspension mounting portions.

A frame and suspension assembly for a vehicle can include a pair of frame members configured to support a load input thereto, a final drive structure connected to each of the frame members such that the final drive assembly is configured to input a load to the frame members, and a stabilizer bar mounted to each of the frame members and extending in a traverse direction of the vehicle over a top of the final drive structure.

Provided is a semi-trailing suspension device including: a trailing arm that is coupled to a vehicle body in a turnable manner; a trailing bush that is provided between the vehicle body and the trailing arm and pivotally supports the trailing arm in a turnable manner; a lower arm that is coupled to the vehicle body in a turnable manner; a lower arm bush that is provided between the vehicle body and the lower arm and pivotally supports the lower arm in a turnable manner; and a hinge mechanism that couples the trailing arm and the lower arm to each other in a relatively displaceable manner.

A suspension system includes: a trailing arm and a lower arm which are turnably connected to a chassis and are joined in such a way as to be displaceable relative to each other through a hinge mechanism; and a stabilizer. The suspension system includes a stabilizer link which connects the stabilizer to the trailing arm. A fitting point of the stabilizer link to the trailing arm is located behind a center axis of the hinge mechanism in a vehicle front-back direction, and a fastening point of the stabilizer and the stabilizer link is located above the fitting point in a vehicle up-down direction and inside the fitting point in a vehicle width direction.

An embodiment rear side member of a vehicle includes a front portion extending forward in a vehicle length direction, a rear portion extending rearward in the vehicle length direction and disposed offset to an inside of the vehicle with respect to the front portion, and a transition portion in a curved shape connecting a rear end of the front portion and a front end of the rear portion and passing through both a first point configured to engage with a first arm of a first type suspension and a second point configured to engage with a second arm of a second type suspension different from the first type suspension.

A vehicle suspension comprises an assembly of a hub carrier and a support arm, the support arm being attached to the hub carrier at two points spaced from each other in the direction of travel and extending inwardly therefrom to a support arm attachment point for fixing to a chassis, and a trailing link extending from the assembly in a direction transverse to that of the support arm, toward a trailing link attachment point for fixing to the chassis. The trailing link preferably extends from the assembly in a forward direction, and is preferably connected directly to the hub carrier. A strut can extend upwardly toward an attachment point for fixing to a chassis, to provide a spring and damper. The support arm can comprise a pair of arms extending divergently from the attachment point to each of the two points. A toe control link extends generally parallel to but spaced from the rear arm, linking the hub carrier to the chassis to provide geometry control under high load conditions. The invention further relates to a vehicle, comprising a chassis and at least two wheels, one on each side of the vehicle, each wheel being attached to the chassis via such a suspension.
