A device for changing the rotational angle position of a pneumatic tire relative to a rim, on which the pneumatic tire is fitted to the rim, includes a manipulating device with a gripper adapted to be rotated by a positionable rotary drive mechanism and having radially adjustable gripper fingers with oppositely facing lift-off devices. Via the gripper it is possible to load a wheel into a clamping fixture, and following unseating of the tire beads from the clamped rim the pneumatic tire can be rotated relative to the rim through a computed angular difference.

To mount a pneumatic tire (R) on a drop base rim (F), the pneumatic tire (R) is gripped by a gripper (2), which is arranged on a handling device (1), on the tread, and the first tire bead thereof is slipped over a flange of the rim (F) by controlled movement of the gripper (2). Subsequently, the gripper (2) is released from the pneumatic tire (R), and the tire (R) is moved into an initial position for mounting the second tire bead by adjustment members (33, 34). Mounting tools (27, 28, 29) arranged on the gripper (2) are guided along on the rim (F) by rotating the gripper (2) about the axis of the rim (F), resulting in the second tire bead being slipped over the rim (F).

A pneumatic tire filling station includes a support and seal arrangement on which one side wall of the tire is supported and sealed, and a tire filling bell that presses and seals against the opposite side wall of the tire and then supplies pressurized air into the tire. The filling bell includes outer and inner rings that are concentrically slidable relative to each other. One of the rings is selected for the filling operation depending on the size of the tire. The support and seal arrangement includes plural plate members that are joined and sealed together to form a continuous support and seal surface, or moved laterally apart to allow a transport apparatus to carry and support the mounted tire from underneath. The tire filling station is adaptable to different models and sizes of mounted tires even in a mixed process flow, in an automated manner.

The invention relates to a method and an apparatus for the unbalance compensation of vehicle wheels in which adhesive weight elements (8) are positioned on at least one determined compensation surface (17) within a disk wheel (7) and are there pressed-on, with a balancing head (1) and a program-controlled handling device (9). The invention is characterized in that the adhesive weight elements (8) in the form of an endless weight strand (5) are fed by a feed device (2) arranged on the balancing head (1) to a following roll-on roller (3). In that regard, the balancing head (1) is arranged stationarily or is connected by a frictional force transmitting connection with an execution arm (10) of the handling device (9), whereby a roll-on roller (3) of the balancing head (1) presses the beginning of the endless weight strand (5) onto the beginning of the compensation surface (17) and thereafter rolls along thereon. In that regard, a length cut-off device (4) is provided in the roll-on roller (3) or before the roll-on roller (3) and cuts-off the endless weight strand (5) of the adhesive weight elements (8) in a determined length.

A device for mounting rotors, in particular articulated shafts, in a balancing machine has a bearing frame (10) and a frame upper part (11), which is mounted on the bearing frame so as to be able to oscillate via spring bars and includes a spindle (12) for rotatable mounting of a rotor. The frame upper part (11) is mounted on the bearing frame (10) via groups of spring bars (19, 19′), said groups (19, 19′) being arranged at a distance from the axis of rotation of the spindle (12) and at a distance from one another, and the longitudinal axes of the spring bars forming the spring bar groups (19, 19′) being oriented parallel to the axis of rotation of the spindle (12). The spring bars forming the spring bar groups (19, 19′) have an elongated, slender shape such that their rigidity in an axial direction is at least 100 times, in particular at least 300 times, greater than their radial flexural rigidity.

A balancing station for positioning and holding a vehicle wheel for the attachment of a balance weight has a clamping device which has at least two mutually opposing jaws designed for pressing against the wheel periphery, the jaws being rotatably mounted around a common clamping axis. At least one jaw is rotatable and movable to and fro in the direction of the clamping axis via a drive. Via a conveyor device the vehicle wheel can be conveyed prone between the jaws of the clamping device. The clamping device can be moved into a tilted position wherein the clamping axis is inclined at an angle of at least 30 degrees from the horizontal out of a basic position wherein the clamping axis of the jaws is aligned substantially horizontally. In this way, weights can be applied particularly ergonomically to the inner face of the wheel.

In a device for clamping the rim of a vehicle wheel, in particular for mounting tires, comprising a shelf (35), onto which the rim may be deposited by one side, and comprising clamping jaws (12 to 15), which may be moved radially relative to the rim, for clamping the rim edge adjacent to the shelf (35), two pairs of clamping jaws (12 to 15), of which the paths of movement intersect at right angles, are provided. The movement of the clamping jaws (12 to 15) is generated by a cylinder (22) and is synchronized by means of a gear unit (27).

For compensating unbalance of vehicle wheels, adhesive weight elements (8) are positioned and pressed onto a determined compensation surface (17) on a wheel (7) using a balancing head (1) and a program-controlled handling device (9). The adhesive weight elements (8) in the form of an endless weight strand (5) are fed by a feed device (2) arranged on the balancing head (1) to a following roll-on roller (3) that presses the beginning of the endless weight strand (5) onto the beginning of the compensation surface (17) and thereafter rolls along thereon. A length cut-off device (4) is provided in or before the roll-on roller (3) and cuts-off the endless weight strand (5) of the adhesive weight elements (8) in a determined length.

Disclosed is a device for feeding and attaching corrective elements for unbalance correction on propeller shafts in a balancing machine, which includes an attachment device adapted to be positioned longitudinally to the rotor axis, with a receptacle for receiving a corrective element attachable to the outer circumference of the rotor. Associated with the balancing machine is a supply unit supplying corrective elements measured for the individual unbalance correction. A feeding device is provided which feeds supplied corrective elements to the attachment device, said feeding device including a transfer shuttle capable of performing reciprocating movements between the supply unit and the attachment device on a guideway parallel to the rotor axis by means of a controllable motion drive mechanism. The transfer shuttle includes a loading device configured for performing an active loading operation by displacing a corrective element from a receptacle of the transfer shuttle into the receptacle of the attachment device, said loading device being driven by means of the controllable motion drive mechanism of the transfer shuttle.
