Vehicle alignment systems and methods are disclosed which operate based on a calculation of “drive direction,” or the direction in which a vehicle is moving. Since a vehicle can be assumed to be a rigid body, each wheel has the same drive direction. Consequently, an alignment parameter of one wheel can be compared to the same parameter of another wheel by equating their drive direction, eliminating the need for the aligner to “see” both sides of the vehicle at the same time. Embodiments include a system having one or more cameras on a fixture carrying a calibration element for an ADAS system, and one or more targets placed on the vehicle to measure the drive direction of the vehicle. The drive direction is assumed to be parallel to the vehicle thrust line and can be used as the line for orientation of the fixture to the vehicle.

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 system for aligning a floor target to a vehicle for calibration of a sensor equipped on the vehicle includes a target adjustment frame with a base frame configured for placement on a floor and a target mount moveably mounted on the target adjustment frame, with the target mount configured to support a target. The target adjustment frame further includes an actuator configured to selectively move the target mount relative to the base frame, and includes a moveable floor target light projector configured to project a light line and be positioned relative to the vehicle. A floor target includes an alignment marker and a calibration pattern, where the alignment marker is configured to be aligned with the light line projected by the light projector to position the floor target relative to the vehicle.

A wheel alignment apparatus for measuring the toe angle of a wheel of a vehicle including an adjustable housing, a scale slider including one or more measurement scales, and a centering marker, and a toe positioning pin projecting from an end of the adjustable housing, the toe positioning pin configured to be rigidly connected to the adjustable housing during operation of the wheel alignment apparatus, wherein the scale slider is adjustable to a plurality of positions within the housing.

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.

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.

An apparatus for chassis measurement for determining the alignment of the wheels of a motor vehicle. The apparatus includes a detachably fixed measurement head apparatus on the vehicle wheel to be measured, wherein the measurement markings are positioned parallel to the front and rear side of the vehicle or the vehicle stand level. After arranging the fastening apparatus and positioning the measurement markings, the laser light source is activated and a plane is projected in space, wherein the length of these laser light lines generates at least intersection points together with the measurement markings, the intersection points of which are detected as track gauge and used for computation in order to determine the fall, trailing and spread data and the virtual longitudinal travel axis of the vehicle. By a camera-assisted measurement value detection apparatus, different electromagnetic spectra for each wheel to be measured are detected and supplied for data processing.

The present disclosure relates to a quick tire self-centering clamp, including a clamp body assembly, a gear and rack transmission mechanism and a locking mechanism, where the clamp body assembly includes a seat body and three guide rails, each of the guide rails is provided with a sliding seat, and a gripping jaw for holding a tire tightly is fixed on the sliding seat; the gear and rack transmission mechanism includes three racks, one end of each of the racks is fixedly connected to the sliding seat and is parallel to the guide rail in opposite directions, a central shaft sleeve is mounted in the seat body, a gear is fixed on the central shaft sleeve; the locking mechanism includes a ratchet, a positioning pin rod and a positioning pin telescopic component. the gear and rack transmission mechanism can increase the adjustment stroke of the clamp.
