A wheel suspension for an at least slightly actively steerable has a wheel carrier for receiving a wheel, a toe link, and at least one further link for connecting the wheel carrier to the vehicle body, and an actuator arrangement having at least one actuator for actively steering the wheel in a first active steering direction and in a second active steering direction. The wheel carrier is formed in at least two parts and has a first wheel carrier part and a second wheel carrier part. The first wheel carrier part is designed to receive the wheel and the second wheel carrier part can be attached via at least one of the further links to the vehicle body, in a non-actively steerable manner. The first wheel carrier part and the second wheel carrier part in a functional state of use of the wheel suspension in a vehicle are movable relative to one another by the actuator arrangement, such that an active, at least slight steering movement of the wheel can be effected.

A wheel suspension for a vehicle includes: a steering knuckle support; a steering knuckle mounted at the steering knuckle support so as to be swivelable around a steering axis; a vehicle wheel mounted at the steering knuckle so as to be rotatable around a wheel rotational axis; and a plurality of links by which the steering knuckle support is articulated at a vehicle frame such that the steering knuckle support is movable in a vertical direction (z) of the vehicle relative to the vehicle frame. A first one of the links is configured as a first control arm configured as a four-bar link, and a second one of the links is configured as a second control arm arranged offset relative to the first link in the vertical direction (z) of the vehicle, and wherein the second link is configured as a two-bar link that is adjustable in length.

The present invention is directed to providing a strut suspension system configured to improve a steering property by reducing steering frictional resistance when a steering wheel is rotationally manipulated and having a relatively simple mechanical structure to reduce the number of components and manufacturing costs and to secure a large space for installing main components such as an engine and the like.

Disclosed is a strut suspension system configured to absorb impact and vibrations transferred to a vehicle body from a road surface through a wheel. The strut suspension system includes a strut provided between the vehicle body and the wheel and to which a knuckle arm connecting a steering system of a vehicle to the wheel is connected to be relatively rotatable when the steering system performs steering and a stabilizer link having one end connected to a stabilizer bar configured to increase roll rigidity of the vehicle body and the other end coupled to prevent the strut from rotating.

There is provided a stabilizer for a vehicle, including a torsion bar fixed to a car body and configured to be rotated about a longitudinal axis of rotation without changing a position, two arm links connected to both ends of the torsion bar, and two drive links connected to each of the two arm links through a ball joint so as to be able to be rotated three-dimensionally, in which the two drive links are configured to, during cornering of the vehicle, adjust a degree of torsion of the torsion bar by rotating about an axis of rotation of a strut assembly or a steering knuckle connected to the two drive links.

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 suspension apparatus for a vehicle including a drive unit configured to provide driving power to a wheel, a first knuckle coupled to the drive unit and configured to transmit a steering force to the wheel, a second knuckle disposed to face the first knuckle and configured to support the first knuckle so that the first knuckle is rotatable, a suspension arm extending from a vehicle body and configured to absorb impact applied to the wheel, a bushing unit provided between the second knuckle and the suspension arm and configured to support the second knuckle so that the second knuckle is rotatable relative to the suspension arm and a rotation restriction unit provided on the bushing unit and configured to selectively restrict a rotation direction of the second knuckle.

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 suspension joining structure may include a lower arm which has one end portion fastened to a vehicle body, an assist knuckle on which a strut portion is located, a fastening unit which is configured so that a second end portion of the lower arm and a lower end portion of the assist knuckle are fastened, a revoknuckle which is pivotally fastened to the assist knuckle to be rotated independently of the assist knuckle to perform the steering of a wheel, and a steering input portion fastened to the revoknuckle and configured to apply a steering force to the revoknuckle upon the steering of the wheel.

The pivot joint assembly includes a housing with an opening which extends along an axis. A bearing is received in the opening and which has a cylindrical outer surface that is in slidable contact with another surface so that the bearing can slide in an axial direction relative to the housing. The bearing has a curved inner bearing surface. The pivot joint assembly also includes an inner ring with a curved outer surface that is in slidable contact with the curved inner bearing surface of the bearing so that the inner ring can rotate and articulate relative to the housing.

The hub carrier (2) and the wheel-guiding link (4), for steering the wheel (3), are pivotally connected to each other such that the hub carrier (2) can be swiveled about a steering axis relative to the wheel-guiding link (4). The hub carrier (2) is directly connected to the wheel-guiding link (4), in a first connection area (20), and the hub carrier (2) is indirectly coupled to the wheel-guiding link (4), in a second connecting area (21), via an integral link (5) connected to a chassis element (12).
