Abstract: Tyre-removal apparatus comprising a base having a support for receiving and rotating the wheel. The tyre-removal apparatus further comprising a frame which is joined to the base and which has an upright with a longitudinal axis substantially parallel to an axis of rotation of the wheel. A support arm is associated with the upright and is movable in a direction substantially parallel to the axis of rotation of the wheel. A tool for operating on the wheel is mounted pivoting on the support arm. A sensor, associated with the tool, is able to detect at least one parameter representing contact between the tool and the wheel, said sensor being operationally connected to a control unit able to control an actuator, associated with the support arm, so as to pivot the tool between a first withdrawn position with respect to the axis of rotation of the wheel and a second advanced position with respect to the axis of rotation of the wheel, depending on the at least one parameter representing the contact between the tool and the wheel.

Abstract: A wheel clamping system, for reversibly clamping a motor vehicle wheel with a rim onto a wheel servicing machine, includes a handle for acting on a rim of the wheel mounted on a rotatable spindle. The handle has a coupling surface for engaging with clamping jaws of a pull rod when the clamping jaws are open. The handle includes a force detecting device for determining an amount of force exerted by the handle on the rim of the wheel, and a signal emitter operatively connected to the force detecting device. The signal emitter is configured to wirelessly transmit a control signal to a signal receiver of the wheel balancer operatively connected to an actuator causing axial movement of the pull rod when the determined amount of force reaches a predefined threshold, such that the actuator is actuated and the wheel clamping system performs a reversible clamping operation.
