A method and associated apparatus for uniquely identifying tyres for wheels of vehicles as part of wheel maintenance processes. The method envisages that a vehicle wheel is mounted on a support of a wheel maintenance apparatus, said wheel comprising a rim and a tyre. Moreover, a digital code is created to uniquely identify the tyre. Finally, via a marking system, preferably of the optical type, at least one marking is created on the surface of one side wall of the tyre of said wheel, corresponding to the previously created digital code.

A balancing device, a uniformity device and an apparatus including the balancing device and the uniformity device are disclosed. Each of the balancing device and the uniformity device includes at least one multi-axis transducer. Methods are also disclosed.

A dynamic balancer includes an outer housing and a spindle assembly rotatably mounted to the outer housing. A frameless motor assembly is connected to selected components of the spindle assembly. A chucking assembly receives a locking member to capture a tire therebetween. The chucking assembly and the locking member are captured in the spindle assembly and rotated by the frameless motor assembly. A spring-biased return cylinder may be used with the dynamic balancer to assist in capturing and releasing the locking member with respect to the chucking assembly. An adjustable encoder assembly may be associated with the motor assembly to monitor a rotational position of the tire and/or spindle assembly.

Disclosed is a wheel end face detection and correction device, which includes a frame, a self-made cylinder, a detection system, a correction system and the like. A wheel is preliminarily positioned in the center, a cylinder II drives an expansion sleeve to descend to match a center hole of the wheel, the attitude of a datum plate is adjusted to attach to a flange face of the wheel, and an expansion core is pulled by a cylinder rod; the cylinder II drives the wheel to ascend, and a servo motor drives the wheel to rotate; a servo electric cylinder II drives a dial indicator to be located below a rim end face of the wheel, a servo electric cylinder I drives the dial indicator to contact an end face of the wheel, and the end face run-out of the wheel may be detected.

A machine body for a wheel servicing apparatus includes a casing and a display support unit configured to support a display unit, such as a touchscreen unit, that is connectable with a processing unit of the wheel servicing apparatus. The display support unit is movably arranged at the casing to provide a first position in which a display front surface of the display unit attachable to the display support unit is visible to a user, and a second position in which a display front surface of the display unit attachable to the display support unit is shielded from the outside such that the display front surface is not visible to the user.

A tire inspection assembly includes a spindle and a clamping mechanism. The tire inspection assembly generally functions to mount a tire and allow for the inflation thereof to perform a test on the mounted tire. The tire inspection apparatus generally offers more robust centering, higher stiffness versus loads, and greater elimination of variable clearances that can otherwise impede repeatability.

The present application discloses a wheel runout detection device. A synchronous gear B is mounted on the output shaft of a servo motor, a synchronous gear A is connected with the synchronous gear B via a synchronous belt, a flange, an expansion sleeve and a cylinder are mounted on a flange plate, and two ends of a connecting shaft are respectively connected with the output shaft of the cylinder and an expansion core. The servo motor drives the flange, the expansion sleeve and the wheel to rotate via the synchronous gear A, the synchronous belt and the synchronous gear B. The device may meet the requirement of wheel runout detection in use, and has the characteristics of ideal effect, high efficiency and high working safety and reliability.

A wheel balancer incorporates tire bead manipulating tools under control of a processing system to apply a clamping pressure to tire sidewall surfaces of a wheel assembly secured to a spindle shaft, facilitating the proper seating of tire beads to the wheel rim. The spindle shaft is operatively coupled to a drive motor and transmission system under control of the processing system, capable of operating in both a high speed, low torque regime and a low speed, high torque regime to rotate the wheel assembly during either an imbalance measurement procedure or a tire bead adjustment procedure. A load roller assembly, under control of the processing system, is disposed to selectively apply a radial force at a tire circumferential tread surface as the wheel assembly is rotated about the spindle axis, further facilitating the proper seating of the tire beads.

Provided is a tire mounting method for mounting tires on a tire holding device 1, wherein the tire holding device comprises a pair of split rim members 4 facing each other, a center axis A of each of the pair of split rim members is on a common predetermined axis O, the tire mounting method includes: a clamping step clamping a tire by the pair of split rim members, and a rotating step, after the clamping step, mounting each bead portion of the tire to the pair of split rim members while rotating the pair of split rim members around the predetermined axis.

An autonomous traverse tire changing bot includes a carriage having a carriage frame with a carriage drive section effecting autonomous traverse of the carriage, along a traverse path, relative to a traverse surface or a floor on which the bot rests, and a bot frame including at least one actuator mounted to the carriage and a bot drive section with a motor defining an actuator degree of freedom, wherein the at least one actuator has an end effector having a tire engagement tool disposed so that articulation of the at least one actuator with the actuator degree of freedom effects engagement contact of the tire engagement tool and a tire mounted on a vehicle, and a controller effects traverse of the bot along the traverse path effecting dynamic positioning of the at least one actuator relative to a variable position of the vehicle with the tire mounted thereon.
