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.

A steering device includes a frame including an upper portion and a lower portion, and a runner moveable relative to the frame at the upper portion of the frame. The runner includes a plurality of segments longitudinally spaced between a first end and a second end. A sensor is configured to detect at least a first segment of the segments. A controller is communicatively coupled to the sensor. The controller is configured to determine a position of the runner based on the detection of at least the first segment and generate one or more signals based on the position of the runner for use in turning one or more wheels.

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 scalable tractive power system for vehicles (car, truck, bus, semi-trailer), integrated with all-wheel steering system which leverage synergies between plurality of differently designed electric traction-motors and all-wheel electric steering-motors is configured with plurality of sensors to virtually eliminate wheel-dragging and EPS, as part of virtually 100% dynamic efficiency. A fully automated electronic clutch-system attached to selected electric traction motors is configured to carry out above 90% traction efficiency by coupling to wheels selected electric traction-motors in their high efficiency range of operation, and de-coupling and replacing electric traction-motors with another electric traction-motors while the vehicle is changing speed or when the vehicle requires higher or lower tractive-power, from forward-motion start to top-rated speed of the vehicle. A holistic controller is configured with multi-objective optimization design (MOOD) procedures computing complex variable values and parameters, finding the required trade-off among design objectives, and improving the pertinence of solutions, while complying with NHTSA's ‘fail operational systems’ for steer-by-wire.

The present application provides a steering mechanism, a vehicle, and an apparatus and method for producing a steering mechanism, and belongs to the technical field of vehicles. Wherein the steering mechanism comprises a first directive wheel, a second directive wheel, a first driving device, and a second driving device. The first driving device is connected to the first directive wheel; and the second driving device is connected to the second directive wheel. The first driving device and the second driving device are configured to separately drive the first directive wheel and the second directive wheel respectively, thus making the first directive wheel and the second directive wheel deflect in the same direction to achieve steering. No linkage relationship exists between the two directive wheels, whereby the two directive wheels do not need to be connected through a complex mechanical transmission mechanism, and a structure of the steering mechanism is simplified.

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.
