Furthermore, the ease of assembling a Hall sensor can be improved, and the defect rate can be reduced.

A wheel steering device for a vehicle, including: a steering knuckle that constitutes a part of a suspension device and that is capable of moving relative to a body of the vehicle in an up-down direction, the steering knuckle holding a wheel such that the wheel is rotatable; and a steering actuator configured to cause the steering knuckle to be pivoted about a kingpin axis so steer the wheel, wherein a caster angle and a caster offset are both 0.

An in-wheel motor unit coupling structure includes an in-wheel motor unit and a shock absorber. The in-wheel motor unit is disposed inside a wheel of a vehicle. The in-wheel motor unit is configured to support the wheel such that the wheel is rotatable. The in-wheel motor unit includes an electric motor that serves as a rotational driving source of the wheel. The shock absorber is coupled to the in-wheel motor unit. The shock absorber is a component of a vehicle suspension. A lower end portion of the shock absorber is fastened to a vehicle center side, in a vehicle width direction, of a motor part so as to be pressed against the motor part outward from the vehicle in the vehicle width direction. The motor part is a part in which the electric motor of the in-wheel motor unit is built.

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 wheeled vehicle includes a vehicle body, a vibration absorbing element, an auxiliary arm, a wheel, and a driving member. The vibration absorbing element includes a first end and a second end. The first end is fixed to the vehicle body. The auxiliary arm includes a connecting end and a free end. The connecting end is connected to the vehicle body. The free end is configured to swing relative to the connecting end. The free end is fixed to the second end. The wheel includes an axle, and the axle is rotationally connected to the free end. The driving member is fixed to the vehicle body and configured to drive the wheel.

A suspension device for an in-wheel motor driven wheel is provided. An upper suspension arm is pivotally supported on the vehicle body for supporting the wheel in a vehicle upper position higher than an axle. A link member pivotally connects the wheel to the upper suspension arm and has an absorber connecting portion connected to a lower end of the shock absorber. The shock absorber connecting portion is disposed in the vehicle bottom position lower than an upper end portion of the in-wheel motor unit. The shock absorber is disposed between the vehicle body and the in-wheel motor unit and inclined so as to be closer to the vehicle body toward the lower end.

A wheel suspension (1) for a wheel (23) of a vehicle, in particular the rear wheel of a utility vehicle, driven by an electric or pneumatic motor (2), having a swing arm (3) which is mounted pivotably around a pivot axis (7) on the vehicle in a first region (4) and is supported on the vehicle in a second region (8), wherein a third region (10) of the swing arm (3) carries a part of the motor (2) which is rotationally fixed in relation to the swing arm (3) in order to transmit a torque to the wheel using a rotating part of the motor (2).

The present disclosure generally relates to an omni-direction wheel system and methods for controlling the omni-direction wheel system. The omni-direction wheel system includes a plurality of suspension systems that operate independently of one another. Each suspension system may include an electromagnetic steering hub configured to rotate a wheel 360 degrees about a vertical axis based on a polarity of an electromagnetic signal applied to the electromagnetic steering hub. The suspension system may further include an in-wheel motor configured to rotate with the wheel and drive the wheel about a horizontal axis.
