A suspension structure of a utility vehicle includes: a shock absorber; a knuckle; and an upper arm and a lower arm which connects the knuckle to a vehicle body frame of the utility vehicle, wherein a recessed portion which is recessed downward is formed on the upper arm, and a lower end of the shock absorber is supported by the recessed portion.

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.

Chassis arrangement for a motor vehicle for passenger transportation, having two axles which are arranged at a spacing from one another in the motor vehicle longitudinal direction and in each case have wishbones with the incorporation of a spring element for the independent wheel suspension system. A first axle, lying at the front in a driving direction, is lowered from a neutral position by from 5 to 50 mm, 10 to 20 mm, in order to drive in said driving direction, and a second axle, lying at the rear in the driving direction, is raised by from 5 to 50 mm, 10 to 20 mm, in each case by way of adjustment of the spring elements, it being possible for the driving direction to be reversed.

A single-wheel drive component for a motor vehicle, having a drive assembly and a wheel carrier, on which a wheel hub, which can be driven by the drive assembly, is rotatably mounted by a wheel bearing. At least one assembly support for mounting the drive assembly on a body of the motor vehicle originates from the drive assembly. It is provided in this case that an assembly bearing for elastic mounting of the drive assembly on the body is arranged on the assembly support. At least one control arm is articulated on the wheel bearing on one side and on the assembly support on the other side, in order to mount the wheel carrier.

A modular chassis is provided for an off-road vehicle to improve assembly, servicing, and repairing of a drivetrain of the off-road vehicle. The modular chassis includes a chassis to support components of the off-road vehicle. A front frame module couples with a front of the chassis, and a rear frame module couples with a rear of the chassis. The front frame module supports lower suspension arms of the off-road vehicle by way of inboard bushing joints. The front frame module supports at least a steering gear and a front differential of the off-road vehicle. The rear frame module is a tube-frame structure that supports components of the off-road vehicle. A lower portion of the rear frame module extends rearward and acutely upward to a top frame member that couples with upper side portions of the chassis. Several cross-members impart structural integrity to the rear frame module.

A tilting vehicle having a steering system actively steering a front axle and a rear axle having two wheels that can be deflected individually in a vertical manner with respect to a vehicle body and that are independent of the steering system. The wheels of the rear axle can be steered by passive steering device configured to generate a steering force because of a vertical deflection of the wheels as the vehicle body tilts to one side. The steering force causing wheels to steer towards the opposite side.

The present invention relates to an active suspension system allowing the force acting axis of a spring to be controlled, wherein a control means for the force acting axis of a spring is installed either between an upper seat plate and an upper arm, or between a lower seat plate and a lower arm so as to allow the wheel rate and vehicle height to be controlled by varying the force acting axis of the coil spring, and a manipulation unit capable of controlling the operation of the control means for the force acting axis of a spring is installed inside the vehicle. By varying the force acting axis of the coil spring, the present invention can significantly improve the marketability of the suspension system and reliability of the vehicle by varying the ride quality.

The purpose of the present invention is to improve the driving stability of a vehicle in which a double wishbone type or multi-link type suspension is adopted. A double wishbone type suspension has a sliding bearing disposed between a coil spring provided coaxially with a shock absorber and an upper support for mounting the coil spring to the body of the vehicle along with the shock absorber, the sliding bearing permitting the coil spring and the upper support to rotate relative to each other. The sliding bearing permits the coil spring and the upper support to rotate relative to each other with torque lower than torque generated by the torsion of the coil spring caused by the load of the vehicle acting on a damper assembly.

A suspension structure of a utility vehicle includes: a shock absorber; a knuckle; and an upper arm and a lower arm which connects the knuckle to a vehicle body frame of the utility vehicle, wherein a recessed portion which is recessed downward is formed on the upper arm, and a lower end of the shock absorber is supported by the recessed portion.
