A chassis for use in a motor vehicle with variably adjustable drive height includes a subframe assembly for fastening wheel suspensions of the motor vehicle, and a plurality of control arms for guiding a wheel carrier. The control arms are fastened to the subframe assembly via control arm attachment points. A plurality of eccentric adjustment devices are provided for adjusting the toe-in and the basic camber of the motor vehicle. An insert element is provided for receiving an eccentric adjustment device. The insert element is arranged within the chassis in such a way that the position of at least one eccentric adjustment device can be varied by varying the arrangement of the insert element within the chassis.

A socket joint having an offset housing configuration and reduced stud diameter can improve steering performance while being able to mate with standard vehicle components. In one implementation, the joint has an offset configuration along with a spherical bearing, where a central housing axis is radially offset from a central stud axis. With the offset configuration, the size of the stud is smaller than with typical joints. In one embodiment, a ratio of the housed stud diameter to the housing outer diameter is between 1:1.5 and 1:2.72. In some implementations, there is a transition surface between the housed stud portion and an attachment stud portion on the stud. One or more helical oil grooves may be located between the transition surface and a retaining ring groove. The retaining ring groove can be used to situate a retaining ring that holds the stud assembly together.

A system for automatic wheel alignment adjustment of a vehicle in an inspection line is provided. The system is disposed under a mounting table mounted with a vehicle and includes a front wheel adjustment apparatus disposed in correspondence with a front wheel of the vehicle and configured to adjust alignment of the front wheel by adjusting a tie-rod and a lock-nut employed in a linkage structure of the front wheel, a rear wheel moving apparatus disposed in correspondence with a rear wheel of the vehicle and slidable in a vehicle width direction, and a rear wheel adjustment apparatus disposed in correspondence with the rear wheel of the vehicle, connectable to the rear wheel moving apparatus, and configured to adjust alignment of the rear wheel by adjusting a cam-bolt and a cam-nut employed in a linkage structure of the rear wheel.

A crane for lifting and transporting loads includes a base frame for transferring the loads of the crane onto a support surface by a plurality of wheels. The wheels are capable of rotating relative to the base frame so as to change the camber angle of the wheels.

A suspension and drive mechanism for a steerable wheel of a vehicle, comprising a wheel support assembly supporting the wheel having a rolling axis and a wheel width defined by inner and outer wheel edges. Front and rear upper control arms coupled between a chassis and the wheel support assembly, and front and rear lower control arms between the chassis and the wheel support assembly. The front and rear upper control arms being coupled to the wheel support assembly above the rolling axis and inboard of the wheel inner edge, and front and rear lower control arms being coupled to the wheel support assembly below the rolling axis and inboard of the wheel inner edge. The control arms are angled so as to establish a virtual steering pivot axis for the wheel support assembly, the virtual steering pivot axis extending transverse of the rolling axis and located within the width of the wheel. The virtual steering pivot axis location varies according to a steering angle of the wheel support assembly as controlled by the steering arm. An electric drive unit arranged within the wheel for driving thereof, and at least one of the virtual pivots that lie on said virtual steering pivot axis lies within the volume occupied by the electric drive unit during at least one point in the steering travel of said wheel.

An active suspension system comprises at least one biasing device configured to support a body from a structure, and at least one motor. A magnetorheological (MR) fluid clutch apparatus(es) is coupled to the at least one motor to receive torque from the motor, the MR fluid clutch apparatus controllable to transmit a variable amount of torque. A mechanism is between the at least one MR fluid clutch apparatus and the body to convert the torque received from the at least one MR fluid clutch apparatus into a force on the body. Sensor(s) provide information indicative of a state of the body or structure. A controller receives the information indicative of the state of the body or structure and for outputting a signal to control the at least one MR fluid clutch apparatus in exerting a desired force on the body to control movement of the body according to a desired movement behavior.
