An adjustable camber and caster bushing. The bushing comprises a planar portion having a first side, a second side, an aperture and an outer perimeter. The bushing also comprises a tubular portion, which is integrally formed with and unitary with the planar portion. The tubular portion comprises an inner diameter, an outer diameter, a first end, and a second end. The inner diameter defines an aperture extending the length of the tubular portion. The inner diameter is tapered, while the outer diameter remains constant. The tubular portion also comprises a slot extending the length of the tubular portion.

The invention relates to a suspension unit, in particular for commercial vehicles, including an arm and a support element. The support element includes a support region and a support-side engagement region and comprises as a single piece, and the arm has an arm-side engagement region. A first engaging structure is provided on the arm-side engagement region, the engaging structure being attachable to a second engaging structure located on the support-side engagement region, and the support region includes a securing portion that fixes an air spring bellows and a rolling surface.

A wheel steering device for a vehicle, including: a steering knuckle that constitutes a part of a suspension device and that is capable of moving relative to a body of the vehicle in an up-down direction, the steering knuckle holding a wheel such that the wheel is rotatable; and a steering actuator configured to cause the steering knuckle to be pivoted about a kingpin axis so steer the wheel, wherein a caster angle and a caster offset are both 0.

An assembly includes a leadscrew defining a central axis, a strut movable along the leadscrew upon rotation of the leadscrew, a camber angle of a wheel changeable according to movement of the strut along the leadscrew, and a motor drivably connected to the leadscrew, the motor defining a motor axis, wherein the central axis of the leadscrew is transverse to the motor axis.

An independently driving wheel module includes: a base frame including an upper end fixed to a coupling surface of a vehicle body, and a rotation part coupled to the upper end of the base frame such that the rotation part is rotatable with respect to the upper end of the base frame; a connection link including a first end integrally coupled to the rotation part, and a second end having a shape extending downward from the first end of the connection link; a driving wheel disposed at a side of the second end of the connection link and coupled to the second end of the connection link; and a rotation plate including an upper and lower surfaces extending obliquely in misaligned directions, the rotation plate being interposed between the base frame and the vehicle body so as to be rotatable with respect to the base frame or the vehicle body.

An assembly includes a leadscrew defining a central axis, a strut movable along the leadscrew upon rotation of the leadscrew, a camber angle of a wheel changeable according to movement of the strut along the leadscrew, and a motor drivably connected to the leadscrew, the motor defining a motor axis, wherein the central axis of the leadscrew is transverse to the motor axis.

A caster angle adjustment device for a vehicle includes a variable lower arm connected to multiple points of a subframe via connection parts and connected to a steering knuckle at a single point via one of the connection pails, any one of the connection pails connected to the subframe being movably connected to the subframe to be changed in shape, and an actuator provided in the subframe and connected to the connection part movably connected to the subframe and configured to move a position of the connection part, so that a position of the steering knuckle is moved through the shape change of the variable lower arm to change a caster angle.

The present invention provides embodiments of modified upper and lower control arms for attachment to the steering knuckle that came with the vehicle, or for attachment to a modified steering knuckle of an embodiment of the invention, such that the steering knuckle, and in particular the wheel hub opening of the steering knuckle, are located at positions that are closer to the front of the vehicle than the positions provided by the control arms that came with the vehicle. The forward position of the wheel hub relative to the position provided by the factory or stock control arms moves the wheel and tire forward by the same distance, thereby allowing much larger wheels and tires to be mounted on the vehicle which do not rub against or interfere with the wheel well, fender or body mount, thereby increasing the approach angle of the vehicle for use in off-road climbing.

A vehicle includes an assembly for providing suspension and steering for a wheel. The assembly includes an inner knuckle and a steering knuckle. The inner knuckle is coupled to an upper control arm at an upper joint and a lower control arm at a lower joint, forming a double wishbone suspension. The upper joint and the lower joint define a first axis. The steering knuckle is coupled to the inner knuckle at a steering joint that forms or otherwise defines a kingpin axis. The steering joint includes a revolute joint, a ball joint, or both. The steering knuckle is configured to be engaged with a tie-rod coupled to a steering mechanism. The kingpin axis is nearer a center of the wheel than the first axis, thus preventing or otherwise limiting torque steer. The upper and lower joints are constrained from significant steering rotation by suitable bushings, anti-steer arms, or both.

A tandem mechanical spring axle/suspension system for heavy-duty vehicles includes a tandem assembly that comprises a front beam of a suspension assembly of a front axle/suspension system, a rear beam of a suspension assembly of a rear axle suspension system, and a mechanical spring. The mechanical spring operatively engages the front beam and the rear beam and extends longitudinally therebetween, as well as operatively engages a main member of the vehicle frame.
