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, and a central rotary element (40) which is rotatably arranged in the center (28) of the wheel clamp (2). Each arm (22, 23, 24) has at least one movable element (32, 33, 34) which is movable in the radial direction in order to permit varying the length of the arm (22, 23, 24) in the radial direction. The wheel clamp (2) comprises furthermore at least two coupling elements (52, 53, 54) which each extend between one of the movable elements (32, 33, 34) and the central rotary element (40) such that the movable elements (32, 33, 34) are movable in the radial direction by rotation of the rotary element (40).

The disclosure provides a tire centering fixture including: a gear, a first rack, a second rack, a third rack, a shaft sleeve, and a guide cylinder. The first rack, the second rack, and the third rack are engaged with the gear. The gear is disposed around the shaft sleeve; the gear and the shaft sleeve are disposed on the guide cylinder. The guide cylinder includes a central cavity and a base wall. The base wall includes a central hole and a circular recess; a lower end of the shaft sleeve is in movable fit with the circular recess of the base wall, and a lower end face thereof is flush with the bottom surface of the circular recess. A locating base is disposed on the upper end face of the guide cylinder and is fixed on the guide cylinder. The locating base functions as an end cover.

A wheel alignment guide that provides a visual indication of the desired placement of an apparatus. The wheel alignment guide includes a body having an opening disposed therein. The wheel alignment guide is configured to surround a portion of the apparatus, such as a wheel, via the opening. In addition, the wheel alignment guide is adapted to rest on a ground surface, being held in place via a charge, such as an electrostatic charge created by static cling vinyl. A wheel of a medical device is disposed within the opening of the wheel alignment guide after a desired position of the medical device is selected. If the medical device is moved during a medical procedure, the medical device may be repositioned due to the placement of the wheel alignment guide. Accordingly, the wheel alignment guide eliminates the need for inefficient markers and potentially-dangerous adhesives, particularly in an operating room.

A maintenance assembly for a wheel assembly of an amusement ride vehicle includes a foundational body, a wheel engagement section extending a first distance from the foundational body, and a datum section including a protrusion extending a second distance from the foundational body. The wheel engagement section is configured to contact a wheel surface of the wheel assembly, and the datum section is configured to contact a pad of the wheel assembly. Additionally, the wheel engagement section is rigidly positioned with respect to the datum section, and the second distance is greater than the first distance, such that the maintenance assembly provides a fixed distance between a surface of the datum section configured to contact the pad and a surface of the wheel engagement section configured to contact the wheel surface.

A system for automatic wheel alignment adjustment of a vehicle in an inspection line is provided. The system is disposed under a mounting table mounted with a vehicle and includes a front wheel adjustment apparatus disposed in correspondence with a front wheel of the vehicle and configured to adjust alignment of the front wheel by adjusting a tie-rod and a lock-nut employed in a linkage structure of the front wheel, a rear wheel moving apparatus disposed in correspondence with a rear wheel of the vehicle and slidable in a vehicle width direction, and a rear wheel adjustment apparatus disposed in correspondence with the rear wheel of the vehicle, connectable to the rear wheel moving apparatus, and configured to adjust alignment of the rear wheel by adjusting a cam-bolt and a cam-nut employed in a linkage structure of the rear wheel.

A system includes a computer including a processor and a memory, the memory storing instructions executable by the computer to determine a recursive standard deviation and a recursive mean offset of a plurality of steering component angles and to identify a wheel misalignment fault upon determining that the recursive standard deviation is below a deviation threshold and the recursive mean offset is above an offset threshold.

The invention relates to a device for measuring and adjusting the parameters of the chassis geometry at a rear axle of a motor vehicle on a production line for the motor vehicle. Gripping and holding means for the rear axle and loading means for the rear axle are associated with the production line. According to the invention, a plurality of interchangeable frames is associated with the production line, and positioning means for positioning one of the interchangeable frames into a position for gripping the rear axle in the production process are associated with the production line. The gripping and holding means for the rear axle and the loading means for the rear axle are associated with the interchangeable frame in question. The interchangeable frames can thereby be matched to rear axles of different vehicle types, such that these different rear axles can be processed in one assembly line.

A spoke angle deviation amount measuring system (2) includes a first to fourth support units (21) to (24) configured to support rotatably a first to fourth tires (11) to (14), respectively. Shaft portions (31d) of the support units (21) to (24) are positioned by positioning caps (55) after a vehicle (3) is moved to a measuring position with a steering wheel (4) positioned neutral. With the tires (11) to (14) inclined at a toe angle with respect to a front-and-rear direction, when the vehicle (3) is caused to travel forwards, lateral stress is exerted on the support units (21) to (24), whereby the support units (21) to (24) turn about the corresponding shaft portions (31d). An angle sensor (40) detects turning angles of the support units (21) to (24). A control device (27) calculates a spoke angle deviation amount based on the detected turning angles.
