A wheel clamp (2) for fastening to a wheel (1), in particular to a wheel (1) of a motor vehicle, comprises at least two arms (22, 23, 24) which extend outward from a center (28) of the wheel clamp (2) in a radial direction. Each of the arms (22, 23, 24) has at least one movable element (32, 33, 34) which is movable in the radial direction. The wheel clamp (2) comprises a locking member (82) which is designed such that the movable elements (32, 33, 34), by operation of the locking member (82), can be fixed such that the movable elements (32, 33, 34) are no longer movable in the radial direction. The wheel clamp (2) also comprises an unlocking member (84) which is designed such that a fixation of the movable elements (32, 33, 34) can be released by operation of the unlocking member (84).

A vehicle steering system comprises: a motor assembly operably coupled to a steering rack, the motor assembly comprising a motor having a rotor and a motor position sensor configured to sense a rotor angle of the motor in a single-turn range; and a rotary-to-linear conversion mechanism operably coupled between the motor assembly and the steering rack, the rotary-to-linear conversion mechanism comprising a rotor operably coupled to the rotor of the motor. A processor calculates an absolute angular position of the pinion in a full-turn range of rotation of the pinion based on the sensed rotor angle of the motor and a pinion angle sensed by a pinion angle sensor in a single-turn range, or based on the sensed rotor angle of the motor and an angle of the rotor of the rotary-to-linear conversion mechanism sensed by an angular position sensor in the single-turn range.

A snap-fit height sensor and a height sensor assembly. The snap-fit height sensor is fixed to a base by means of a mounting support. The height sensor comprises a sensor body and a swing arm capable of swinging relative to the sensor body. An engagement seat is provided on the sensor body, the engagement seat being capable of receiving the mounting support and being fitted and fixed to the mounting support. The snap-fit height sensor and height sensor assembly provided in the present utility model overcome the shortcomings in the prior art, such that the mounting support and sensor have a small mounting volume, a light weight and a low cost, with simple mounting steps, few components and high efficiency.

A method for the diagnostic assessment of the wheel alignment of a vehicle (2) equipped with wheels (3) having tyres (301) coupled to respective rims (302), comprises the following steps: in a longitudinal movement of the vehicle (2) in a forward travel direction with one wheel (3) on a longitudinal track (4A), until the wheel (3) surmounts a measuring platform (5A) located along the track (4A), acquiring a forward travel measurement signal, representing a lateral force applied to the platform and directed transversely to both the longitudinal direction and the weight force at a forward travel instant at which the wheel surmounts the measuring platform (5A) as it moves along the track (4A) in the forward travel direction; in a longitudinal movement of the vehicle (2) in a return travel direction opposite to the forward travel direction with the wheel (3) on the track (4A), until the wheel (3) surmounts the measuring platform (5A), acquiring a return travel measurement signal, representing a lateral force applied to the platform (5A) and directed transversely at a return travel instant at which the wheel (3) surmounts the measuring platform (5A) as it moves along the track (4A) in the return travel direction; processing the forward and return measurement signals in order to determine, for the wheel (3), at least an angle of camber and/or toe.
