Problems solved by technology

During, and especially at the end of, the mounting or removal operation, when the tire is fully moved into the bottom of the rim, the frictional forces at this traction location or region may become particularly high, so that there is a risk of stressing the tire material. danger of loss

Embodiment Construction

[0049] figure 1 Illustrated is a tire changing apparatus comprising a vertical support frame 14 at which a mounting tool 4 and a removal tool 5 can be moved during mounting operations (eg image 3 shown schematically) or during disassembly operations (such as figure 2 shown schematically) is kinematically guided to the corresponding position.

[0050] The wheel comprising rim 2 and tire 1 can be positioned and fixed on a rotating support 12 by means of self-centering means 13 . The rotary support 12 and the wheel can be rotationally driven by the electric motor 3 during the mounting operation and during the demounting operation. The torque of the electric motor 3 is transmitted to the rim 2 through the rotating support body 12 . Pull position or pull area 17 ( Figure 4 ) causes the tire 1 to rotate together with the rim 2 relative to the mounting tool 4 during the mounting operation or relative to the demounting tool 5 during the demounting operation. exist Figure 4 ...

Abstract

The present invention is related to a method and an apparatus for assembling a tyre (1) onto the rim (2) of a vehicle wheel or for disassembling a tyre (1) from the rim (2) of a vehicle wheel. There is provided an electric motor (3) for rotationally driving the rim (2) and the tyre (1) during the assembling or disassembling operation, tools (4, 5) for assembling or disassembling the tyre (1) onto the rim (2) or from the rim (2), measuring means (6, 15, 16, 18) for measuring the tyre temperature and / or forces acting on the tyre during the assembling or disassembling operation, and recording means (7) for recording on at least one data carrier the measured values of the tyre temperature and / or of the forces acting on the tyre during the assembling or disassembling operation.

Description

technical field [0001] The present invention relates to a method and a device for mounting a tire on or removing a tire from the rim of a wheel. Background technique [0002] EP2100756B1 discloses a method and apparatus for mounting a tire on the rim of a wheel, wherein the core temperature of the tire is measured prior to the mounting operation. The method and device are particularly useful for mounting runflattyres or UHP (Ultra High Performance) tyres. The core temperature should be between 15°C and 20°C for installation operations. [0003] DE4205045C2 describes a method and a device for mounting a tire on the rim of a wheel, wherein the current consumed by the electric motor during the mounting operation is measured to control the amount of current supplied to the motor until a predetermined maximum amount of current is reached. [0004] During installation operations and during removal operations, the rim and tire are driven by torque delivered from the electric moto...
