A tyre changing apparatus (1) comprises: a frame (10); a supporting element (11) for supporting a wheel (2) rotatably about an axis of rotation (A); an arm (12) movably connected to the frame (10) to be moved by an actuator (5B, 5B) along a direction of movement (B) parallel to the axis of rotation (A); a bead breaker tool (13) connected to the arm (12) to move between an activated position, where it is in contact with the tyre (3), and a deactivated position, where it is spaced from the tyre (3); a control unit (14). The bead breaker tool (13) includes a mounting element (13A) and a bead breaker disc (13B) which rotates freely relative to the mounting element (13A) and comprises a sensor (131), configured to generate a contact signal (132) representing a rotation of the bead breaker disc (138) relative to the mounting element (13A); the control unit (14) is connected to the sensor (131) to receive the contact signal (132).

A system is provided for placement of noise attenuating foam along an inside surface of a tire to attenuate cavity noise. The system can be used with tires of various sizes and shapes such that different foam sizes may be utilized. The system provides for automating the process of foam placement in a manner that allows for consistent placement of the foam during e.g., tire manufacture.

The present invention provides a tire lifting device that allows an operator to lift vehicle and remove vehicle tires remotely, thereby providing a more efficient and effortless vehicle tire removal operation to the operator. The device is configured to capture, remove, replace, and minutely position vehicle wheel and tire for easy re-installation without involving lifting by the technician. The device further is powered by hydraulic and or electric operation. The device comprises a steel frame with at least at least two fixed wheels, at least one steerable wheel and drives for steering the device over surface. The device further comprises a remote control unit to perform complex motions of the device remotely. A main jack and roller stand raises and lowers the wheel and tire for height positioning, while a support tubes and tire guide hold the tire erect either for removing or remounting the vehicle tire.

A fixture for eccentric clamping of a wheel is composed of a base (1), a cylinder (2), a cylinder support (3), a connecting seat (4), a movable positioning seat (5), a guide rail sliding seat (6), a linear guide rail (7) and a fixed positioning seat (8), wherein the cylinder support (3), the linear guide rail (7) and the fixed positioning seat (8) are fixed on the base (1), the cylinder (2) is mounted on the cylinder support (3), an output shaft of the cylinder (2) is connected with the connecting seat (4), the connecting seat (4) is connected with the linear guide rail (7) via the guide rail sliding seat (6), the movable positioning seat (5) is fixed on the connecting seat (4), and the cylinder (2) is configured to drive the connecting seat (4) and the movable positioning seat (5) to move along the linear guide rail (7).

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.

A tire testing machine is for testing a tire, comprising a free roller section configured to include a plurality of rollers having an endmost roller disposed downstream of a lubricator in a conveying direction and farthest from a predetermined reference position, the endmost roller being disposed such that a horizontal distance from the reference position is equal to or greater than a radius of a largest of a plurality of tires set in advance as objects of application of a lubricant.

A tire management method with which specific information of a tire can be acquired at arbitrary timing in a manufacturing process of a vehicle is provided. The tire management method is a method of managing a tire group including a plurality of tires 1 on each of which a first mark M1 and a second mark M2 are provided on specific positions of a side surface, the method including: a step of associating, with respect to each of the tires included in the tire group, specific information of the tire and mark positional information (12, r1, and r2) related to positions of the marks M1 and M2, and recording these into a computer 2; a step of acquiring mark positional information of a tire selected from the tire group; and a step of acquiring, by using the computer 2, specific information associated with the previously-acquired mark positional information.

A vehicle wheel service apparatus that includes: a frame; a plurality of working tools, connected to the frame and movable to perform operations for mounting and/or demounting the tyre relative to the wheel rim; a shaft driven by an actuator rotationally about a longitudinal axis and connectable to the rim; a measuring system for generating vibration signals representing vibrations of the shaft produced by wheel imbalances; a control unit, connected to the measuring system to receive the vibration signals; a support device, connected to the frame and movable between an activated position, where it encircles the shaft while still allowing it to rotate, and a deactivated position, where it is spaced from the shaft; a connector, movable between a working position, where it mechanically connects the measuring system to the frame, and a rest position, where the measuring system is mechanically disengaged from the frame.

The method for assembling a set of construction elements (1) comprises at least the following steps: a) assembling two complementary external faces of two construction elements (1) by adhesion, b) continuing the assembly carried out in step a) by adhering other faces of the elements (1) to complementary external faces of other construction elements (1) until a predefined portion of a building or engineered structure is obtained, c) adhering sheets (15, 16), so-called cladding sheets, made of a wood-based material to at least a portion of the coplanar faces of the elements (1) assembled in the preceding steps, d) repeating steps a) to c) until the part is obtained. The invention also relates to a building made with at least three elements assembled according to the method of the invention.
