Systems are provided for suspensions that deliver desirable wheel kinematics at prescribed conditions. A system includes a vehicle body structure with an engine cradle, and an associated wheel assembly. A suspension system links the wheel assembly with the engine cradle, and includes a link coupled with the engine cradle and coupled with the wheel assembly. A joint at the link includes a flange that has an opening, an edge, and at least one undercut defined in edge of the flange. The joint allows release of the wheel assembly from the engine cradle by designed tearing between the opening and the at least one undercut. The release is initiated only under loads above a select threshold at the joint, to provide select kinematics of the wheel assembly for specific operational cases.

A vehicle suspension system smoothly changes a vehicle posture with respect to a steering force and a steering angle by minimizing a kinematic roll at an initial turning stage, thereby allowing a driver to obtain the sensation of maneuvering the vehicle well. The suspension system includes a front suspension having geometry satisfying that a caster angle is +3° to +5°, a caster trail is +20 to +30 mm, an intersection point between a kingpin axis and ground is located on an inner side in a vehicle width direction of a center of a tire contact patch, and an anhedral angle of a lower arm is +2.8° to +7.2°. Arear suspension includes five links and has geometry satisfying that a virtual kingpin axis extends near the center of a tire contact patch of a rear wheel assembly and extends vertically at −2° to 0°.

A steering system including a plurality of steering devices respectively provided for a plurality of steerable wheels that belong to at least one of a front-wheel side and a rear-wheel side of a vehicle, wherein the plurality of steering devices respectively include a plurality of steering actuators, and wherein each of at least one of the plurality of steering actuators is disposed on an inner side of a corresponding one of side members of the vehicle.

A void bushing for a vehicle suspension is configured to have protrusion parts formed to protrude outwards on a bulge part of an inner pipe. The protrusion parts are located to be disposed in oblique line directions between void portions of an elastic body that is filled between the inner pipe and an outer pipe. In the void bushing, ride comfort characteristics and durability characteristics of a vehicle may be maintained, as they are, under favorable conditions by the void portions. Further the handling response characteristics of the vehicle may be advantageously improved by promoting a rigidity increase through the protrusion parts.

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.

The control arm assembly includes a control arm body and a socket assembly for connecting the control arm body with a vehicle frame. The socket assembly includes a housing with an inner bore which extends along a vertical axis between opposite open ends. A stud extends past the open ends and has an axially extending through passage. The stud has a pair of end portions on opposite sides of a ball portion that has a curved outer surface which is in sliding contact with a bearing surface for allowing the control arm body to pivot relative to the stud and the vehicle frame. 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 system including a plurality of steering devices respectively provided for a plurality of steerable wheels that belong to at least one of a front-wheel side and a rear-wheel side of a vehicle, wherein the plurality of steering devices respectively include a plurality of steering actuators, and wherein each of at least one of the plurality of steering actuators is disposed on an inner side of a corresponding one of side members of the vehicle.

A transverse link has an inboard side and an outboard side. A steering knuckle has an upper end, a wheel supporting section and a lower end. The lower end is pivotally coupled to the outboard side of the transverse link. A strut has an upper end and a lower end. An upper knuckle breakaway structure attaches the upper end of the steering knuckle to the lower end of the strut. The upper knuckle breakaway structure has a frangible part that releases the upper end of the steering knuckle from the lower end of the strut upon application of a prescribed rearward directed force. A transverse link breakaway structure couples the inboard side of the transverse link to a lower suspension support structure such that upon application of the prescribed rearward directed force the inboard side of the transverse link is released from the lower suspension support structure.

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.
