The present invention regards a group for bead releasing a tyred wheel and/or for thrusting a portion of a tyre (T) of a tyred wheel (TW), and such group comprises a base, a supporting column rising from the base, a tool-supporting arm extending from the supporting column and a bead releasing and/or thrust tool supported by the tool-supporting arm.

Described herein is a process for mounting a tire onto a wheel. The process comprises positioning the tire in respect to the wheel such that a first arc of the bottom bead extends between the wheel's top and bottom bead seats. Next, two fingers are placed in contact with the bottom bead at locations immediately adjacent to opposing ends of the first arc of the bottom bead. The first finger rotates about the central axis in a rotational direction away from the first arc of the bottom bead while applying a force in a direction of the bottom bead to advance all of the bottom bead below the top bead seat. These steps are repeated with the top bead to advance all of the top bead below the top bead seat. During the process, the first finger and the second finger may not contact any portion of the wheel.

Described herein is a method for dismounting a tire from a wheel assembly. The method may comprise inserting at least a first finger and a second finger between a top bead of a tire and a top bead seat of a wheel, pulling a portion of at least the top bead past a plane defined by the outer edge of the top bead seat, and moving the first finger in a first rotational direction away from the second finger. Also described herein is a finger for dismounting a tire from a wheel. The finger may comprise at least one roller having two opposing ends, each end connected to a corresponding end of a roller nest of the finger. Also described herein is an apparatus for removing a tire from a wheel. The apparatus may comprise a wheel alignment assembly, a tire dismount assembly, a bead lifter, and a rotation assembly.

Method and related apparatus for determining the geometrical dimensions of a wheel, or at least one part of a wheel, with particular reference to vehicle wheels, in the context of a wheel maintenance process. This method uses contactless sensors which comprise a scanning radar system, preferably a millimeter-wave radar system, to scan the wheel, or at least one part of the wheel, quickly and accurately.

Apparatus and method for mounting a tire on a rim of a wheel and/or for removing a tire from a rim of a wheel of a vehicle. This apparatus is generally known as a tire changer. The tire changer of the present invention uses contactless sensors, in particular radar sensors, to scan the geometric dimensions of the wheel to be maintained and, in general, to accurately control the mounting/demounting tools.

A tire defect detection system for detecting defects in a tire. The system includes at least one infrared camera, a pneumatic source and a computing device. The pneumatic source inflates the tire to a predetermined pressure. After inflation, the infrared camera captures a reference frame of a section of the tire. A period of time after capturing the reference frame, the infrared camera captures a subsequent frame. The subsequent frame is compared to the reference frame to detect a portion of the section of the tire that has a lower temperature. The lower temperature is caused by an escape of air from the tire through a defect. The escaping air cools the area of the tire around the defect, so a decrease in temperature indicates the defect.

A combined tire-disassembling device is provided, and includes a first shaft with a pressing wheel at an end of the first shaft, and a second shaft with a disassembling and assembling hook at a first end of the second shaft, where a combined frame is provided on the first shaft, a shaft hole matched with the second shaft is provided in the combined frame, one end of a driving oil cylinder of second shaft is connected with the second end of the second shaft, and the other end of the driving oil cylinder of second shaft is connected with the combined frame. A large horizontal tire changer is further provided, which includes a base platform, a sliding platform provided at one end of the base platform, a chuck assembly and a tire disassembling mechanism a hydraulic driving device and an operating console.

The present invention discloses a tire changer including: a base; a wheel holder mounted on the base; and a tool bearing device that is arranged on the base and can drive a disassembly tool to move in the horizontal and vertical directions, and further including: a slider; a supporter; and a first driving device, wherein the supporter is fixed on the base; the tool bearing device is fixed on the slider; the first driving device is connected to the slider and the first driving device can drive the slider to slide along the vertical direction on the supporter. The tire changer has the advantages of small footprint, saving operating procedures, and improving work efficiency, etc.
