ABSTRACT:
A spindle mounting for a wheel balancing machine of the kind in which the spindle is arranged substantially horizontal and has a cantilevered end portion for receiving a wheel to be balanced. The mounting includes a housing for rotatably supporting the spindle, and flexible support means connecting that housing to a base which is securable to a frame of the balancing machine. The support means includes at least three elongate support members which extend transverse to the spindle axis and are arranged in spaced side by side relationship, and an elongate restraining member arranged substantially parallel to the spindle. The support members are connected between the housing and base to provide column supports for the housing, and the restraining member has its opposite end portions connected to the housing and base respectively to hold the housing against endwise movement relative to the base. Each support member and the restraining member has sufficiently low lateral stiffness to permit relatively free lateral movement of the housing relative to the base in a plane extending transverse to the support members. A pair of force transducers are secured to the base and are connected to the housing through elongate reactor members so as to respond to lateral movement of the housing by generating a signal characteristic of the force causing that movement, and each reactor member is elongate and has sufficiently low lateral stiffness to substantially limit the transducer response to those forces acting in the aforementioned plane laterally of the spindle.
