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 drop-out mounting structure for wheel alignment is disclosed. The disclosed drop-out mounting structure for the wheel alignment according to an aspect of the present disclosure for mounting a drop-out member as a wheel mounting unit to a bicycle frame through a bolt in a state that the drop-out member may be set according to a predetermined reference position includes a wheel alignment unit provided to be in spherical contact with a bolt fastening portion of the drop-out member and the frame as a male and female type and performing wheel alignment according to deformation of the frame.

Methods and apparatus are provided for attaching a wheel alignment instrument of a wheel alignment system to at least one stud of a wheel of a vehicle, including a plurality of mounting tools, each having a first body and a second body that move relative to each other so that the second body grippingly engages the wheel stud. A bracket attached to each of the mounting tools extends between the mounting tools.

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.

An improved turntable, adapted to detect, correct and/or adjust wheel alignment of a vehicle, includes a fixed base to be positioned on a surface; a movable assembly, mounted onto the fixed base so as to rotate and translate with respect thereto and having an upper plate that receives and supports a wheel and a lower disk integral with the upper plate; a locking mechanism associated with the fixed base, which interacts with the lower disk of the movable assembly; an actuator that causes the locking mechanism to pass from a first condition, in which the mechanism limits and counters translations of the lower disk in a lying plane while allowing rotations of the disk about an axis perpendicular to the lying plane, to a second condition, in which the mechanism allows free translations of the lower disk in its lying plane and free rotations of the disk about such axis.
