The through passage is eccentrically located in a radial direction on the stud for translating the control arm body relative to the vehicle frame in response to rotation of the stud relative to the housing to adjust a camber angle of the wheel assembly.

A steering shock absorbing structure for an in-wheel motor includes: a steering input unit configured to detect a steering angle of a steering wheel; a steering unit fastened to the steering input unit, and configured to steer a wheel according to the steering angle of the steering input unit; a tilting unit having a first end connected to the steering unit and a second end connected to the wheel, and configured to be tilted with respect to the steering unit; and a controller configured to selectively drive the tilting unit.

A vehicle strut assembly includes at least a strut member, a bearing assembly, a mounting bracket and a noise isolating member. The bearing assembly encircles an upper end portion of the strut member. The mounting bracket is configured to receive the bearing assembly with mounting bracket encircling the upper end portion of the strut member and further configured to attach to a portion of a vehicle body assembly of a vehicle. The noise isolating member is installed below the mounting bracket and along a surface of the bearing assembly reducing noises transmitted from the vehicle strut assembly to the portion of the vehicle body assembly.

A self-tightening and wear-compensating suspension mounting system is described herein. The suspension mounting system may include a housing, a hemispherical race, a hemispherical ball, an elastomeric first bushing, two opposing couplings, and a shock absorber. The housing includes two opposing cavities. The hemispherical race is mounted within a first cavity of the two opposing cavities. The hemispherical ball is slidably mounted at least partially within the hemispherical race. The elastomeric first bushing is positioned at least partially within a second cavity of the two opposing cavities. The two opposing couplings are positioned hold the hemispherical race, the hemispherical ball, and the elastomeric first bushing between the two couplings. The shock absorber shaft extends through the two opposing cavities, the hemispherical race, the hemispherical ball, and the elastomeric first bushing. The hemispherical ball pivots within the hemispherical race responsive to movement of the shock absorber.

A suspension thrust bearing provides a bearing with annular upper part and annular lower part. The lower part provides an axial hub, an outwardly projected radial flange extending from the axial hub, and a curved connecting portion between the axial hub and radial flange. The lower part provides an exterior support surface that axially supports an upper end of a suspension spring by a damping device made from resilient material. The exterior support surface provides at least one longitudinal groove, the damping device including an interior surface contacting the exterior support surface and including a complementary shape to mate with the groove. The groove extends along the connecting portion, disposed in a recessed portion between two longitudinal side walls, a first groove end on or directed towards the hub, and a second groove end on or directed towards the flange, the second groove end being a transverse wall.

An electric vehicle frame strut tower to body structure interface bracket is disclosed. An example electric vehicle disclosed herein includes a frame, a battery pack supported by the frame, a body coupled to the frame, a strut tower coupled to the frame to support the body and absorb road surface impacts on the electric vehicle, and a strut tower interface bracket to couple the strut tower to the body.

A vehicle suspension system includes a frame, a damper and a rocker arm. The frame is connected with the rocker arm through the damper, the swing part of swing arm limits the swing arm's rotation angle by matching the limit structure on the frame; the bottom of damper is provided with the universal structure, the damper is connected with the rocker arm through the universal structure, and the universal structure controls the damper in free deflection. A deviation motion of vehicle wheels on both ends by coordinating the swing arm, vibration damper, etc. to avoid the slipping and rollover due to great sides way upon vehicle steering and the lateral wheels disengagement from ground and to enhance the safety of cornering driving of vehicles.

A suspension joining structure includes: a lower arm having one end fastened to a vehicle body; an assist knuckle having a strut thereon; a fastening unit configured to connect one end of the lower arm and a lower end of the assist knuckle to each other; a suspension fastened to the assist knuckle and rotating independently of the assist knuckle for steering of a wheel; a steering input part connected to the assiste knuckle, and configured such that a steering force is applied to the suspension upon steering; and a rotation transfer unit arranged between the suspension and the steering input part.

A damper mount structure improves accuracy of positioning to increase assembling efficiency and includes a damper mount for fixing an upper portion of a suspension device to an attachment opening formed in a vehicle body. The damper mount includes: a housing to be mounted on the upper portion of the suspension device; a stay which protrudes from an outer circumferential surface of the housing and is brought in contact with a lower surface of a circumferential edge of the attachment opening in a state that the housing has been inserted through the attachment opening to attach the housing to the circumferential edge of the attachment opening; and a plurality of ribs which connect the stay with an outer circumferential surface of the housing. A first rib, a second rib, and a third rib include side surfaces, respectively, facing an inner circumferential surface of the attachment opening.
