A wheel suspension includes an axle limb which supports a wheel. The axle limb includes a first steering axle which provides a first steering angle in a specified range for the wheel, and components for connecting the axle limb to a support structure. At least one of the components includes a second steering axle which is selectively releasable in order to provide a steering angle which is different than the first steering axle. The components for connecting the axle limb to the support structure form a McPherson suspension.

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 assist 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 vehicle wheel having a suspension and a steering device is capable of not only simplifying a driving system but also reducing the number of parts and reducing weight. The vehicle wheel includes a suspension combined with a damper and a spring in a housing of a stator of an in-wheel motor embedded in each wheel of a vehicle and a steering device directly connected to the suspension.

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 independent suspension system for a vehicle includes: a steering unit configured to be controlled to adjust the steering angle of a wheel, a shock absorber engaged with the wheel and configured to absorb impacts applied to the wheel and including a first shock absorber and a second shock absorber, each of which arranged in a forward-rearward direction on opposite side surfaces of the wheel, and a link unit disposed between the shock absorber and the steering unit in order to vary the distance between the wheel and the steering unit. The link unit includes a first upper arm disposed between the first shock absorber and the steering unit, a second upper arm disposed between the second shock absorber and the steering unit, and at least one ground clearance adjustment unit engaged with the first and second upper arms in order to vary the distance between the first and second upper arms.

Provided are a steering function-equipped hub unit that has a simple structure, high rigidity and a reduced size, a steering system, as well as a vehicle including the steering function-equipped hub unit. The steering function-equipped hub unit includes: a hub unit main body including a hub bearing supporting a wheel; a unit support member provided to a knuckle of a suspension device and rotatably supporting the hub unit main body about a turning axis extending in a vertical direction; and a steering actuator configured to rotationally drive the hub unit main body about the turning axis. The hub unit main body is supported by the unit support member through a preloaded rolling bearing.

A wheel-mounting assembly for a utility vehicle includes a chassis and a wheel support assembly mounted to respective outboard ends of first and second telescopic axle assemblies. The first and second telescopic axle assemblies are laterally spaced from one another and are each secured to the chassis. The first and second telescopic axle assemblies each include a respective actuator arranged to control extension and retraction thereof for steering and track-width control.

A suspension is provided which can not only generate a damping force between sprung mass and unsprung mass but also steer a wheel. A suspension includes: a shaft coupled to sprung mass of a vehicle, the shaft having a screw groove and a spline groove formed thereon; a ball screw nut assembled to the shaft via a ball; a ball spline nut assembled to the shaft via a ball; a ball screw-specific motor connected to the ball screw nut; a ball spline-specific motor connected to the ball spline nut; and a case coupled to unsprung mass of the vehicle, the case being configured to hold the ball screw-specific motor and the ball spline-specific motor. The ball spline-specific motor rotates the ball spline nut and the shaft relative to the case.

A movable object includes: a steering part including a wheel provided to rotate along a ground, a wheel rod connected to the wheel and extending in a direction away from the wheel, and a steering motor connected to the wheel rod to rotate the wheel rod and steer the wheel; and a cover part disposed on top of the steering part, and including a receiving member in which a portion of the steering part is received. When the steering motor rotates the wheel rod in one direction, the steering part is engaged with the receiving member so that the steering part and the cover part may be joined, and when the steering motor rotates the wheel rod in an opposite direction, the steering part is separated from the receiving member so that the steering part and the cover part may be disengaged.
