In a method of setting a displayable machine function of a wheel balancing machine, machine functions stored in a function setting device are addressed and simultaneously displayed and identified at a display device by means of a movably mounted sensing member which senses dimensions of a wheel to be balanced.

Method of setting a displayable machine function of a wheel balancing

A method and device for balancing an unbalance on a motor vehicle wheel, including a tire mounting portion that is provided with a stylized design. Such a wheel can include a supporting disk with openings therein defining radially extending, spaced apart support members, such as struts or spokes, in the main area of the wheel. In particular such a tire supporting disk can comprise light metal. The angular positions of the radially extending support members are determined and are stored in storage 2 and the measurement values determined in the measurement procedure are divided into balancing corresponding to the angular positions of the radially extending support members. Weights for balancing the wheel are determined and are attached to the supporting disk at angular positions corresponding to the locations of the support members.

A mechanical drive arrangement for a measuring spindle of a wheel balancing machine has an actuator in the form of a lever which is actuable by hand for producing a torque which is transmitted to the measuring spindle for driving same.

Mechanical drive arrangement for a measuring spindle of a wheel

In a method and apparatus for measuring static unbalance of a rotary member, involving determining the axial moment of inertia of the rotary member which is mounted pivotably in a horizontal position in a balancing system, about an axis of the balancing system, a deviation of the rotary member from its horizontal position is detected and a return force for returning the rotary member to the horizontal position is produced in response to a control parameter from a regulating circuit in dependence on the detected deviation, with regulation of the return force also being effected in dependence on the weight of the rotary member. The value of the static unbalance of the rotary member is formed from the measured return force.
