Disclosed are a hub paint spraying traceless transfer method and equipment Aiming at the problem of paint film damage in the existing wet-film paint sprayed hub transfer process, the transfer method and equipment are used for transferring a wet-film hub between a spraying ground chain and an oven ground chain, and a clamping jaw of a robot clamps a tray in the transfer process to complete transfer of the wet-film hub, so that damage of the paint surface due to direct contact is avoided and the overall quality of the hub product is improved.

A vehicle wheel positioning device, including a frame, a jacking cylinder and two sliding sleeves fixed on a bottom plate, the outputting end of the jacking cylinder is connected with a top plate, and a belt pulley connected to a servo motor via a shaft. A vehicle wheel may be positioned via the top plate during a vehicle wheel finish turning automation processing, without switching programs for automation production of the wheel with different wheel widths and different offset distances.

A dolly for supporting a tyre of a motorcycle or motor scooter off the ground is provided. The dolly comprises: axially aligned wheels supported by a frame which has a frame part forward of the wheels and a frame part behind the wheels, the forward frame part having an open end being such that the motorcycle or motor scooter tyre can locate in the open end, at least one tyre gripping member on the forward frame part and adapted to wedge the tyre when the forward frame part is lifted and release the tyre when the forward frame part is lowered, and a wheel on the frame part behind the wheels.

An automatic anti-slipping system for a rotationally fixed attachment of a rim of a wheel in a wheel service machine, comprises a wheel supporting and rotating means (20), for supporting and rotating a wheel to be serviced. At least two driving pins (32) are provided at the wheel supporting and rotating means (20) for reversibly generating a rotationally fixed connection between a wheel supporting and rotating means (20) and a rim of a wheel to be serviced, wherein at least one of the at least two driving pins (32) is adapted to come in a positive locking engagement with at least one recess of a rim, and wherein the at least two driving pins (32) are adapted to be reversibly moveable, and actuator means (40) are able to reversibly move the driving pins (32) in an actuated state.

A tire work stand comprises a frame for supporting the work stand on a ground surface and for attaching a set of components to the tire work stand. A plurality of rollers is attached to the frame to support a tire above the ground surface and to permit rotation of a tire during inspection of the tire. A ramp is configured to have a first ramp end capable of extending from the ground surface and a second ramp end extending to a position proximal to the frame. A bridge is configured to have a first bridge end extending from the second ramp end and a second bridge end extending to a position proximal to a surface of at least one of the rollers, wherein the bridge acts to inhibit rotation of the roller during loading of the tire and further permits rotation of the tire after the tire has been loaded on the tire work stand.
