Synchronization of tyre bead breaker tools

摘要

An apparatus and a method for synchronously moving first and second fitting or removal tools (300, 400) of a tire fitting or removing apparatus. When an operator moves the first fitting or removal tool (300) in a substantially radial direction with respect to a longitudinal axis (L) of a post (210) supporting the first and second fitting or removal tools (300, 400), a synchronization unit receives first and second input signals of first and second sensors (320, 420) coupled to the first and second fitting or removal tools (300, 400) and indicating a radial movement or position of the tools (300, 400). The synchronization unit generates, based on a comparison of the first and second input signals, an output signal causing an actuator (450) to move the second fitting or removal tool (400) synchronous to the first fitting or removal tool (300) in said substantially radial direction.

主权项

1. An apparatus for fitting a tyre onto a rim of a vehicle wheel and for removing a tyre from a rim of a vehicle wheel, comprising:
a base having a receiving means for receiving and at least rotationally moving the wheel, a frame coupled to the base and having a post with a longitudinal axis parallel to a rotational axis of the received wheel, a first fitting or removal tool and a second fitting or removal tool which are supported by the post, wherein the first and second fitting or removal tools are movable at least in an axial direction and a substantially radial direction with respect to the longitudinal axis of the post,
characterized by a first sensor coupled to the first fitting or removal tool and adapted to detect the movement of the first fitting or removal tool in said substantially radial direction, an actuator coupled to the second fitting or removal tool and adapted to move the second fitting or removal tool in said substantially radial direction, and a synchronization unit adapted to receive a first input signal from the first sensor indicating a movement or position of the first fitting or removal tool in said substantially radial direction, and provide, based on the first input signal, an output signal causing the actuator to move the second fitting or removal tool synchronously to the first fitting or removal tool in said substantially radial direction.
