ABSTRACT:
A washing apparatus is provided for washing the exterior surface of a vehicle. The apparatus is made of a frame, an arm pivotably attached to the frame and extending along the vehicle path which is provided with a support plate for suspending a generally vertical rotatable wheel having a central shaft operatively driven by a drive motor. An elastic coupling mounts the wheel and associated drive motor upon the support plate. The coupling includes a mounting plate spaced above and generally parallel to the support plate and is separated by at least one elastic member radially spaced from the wheel axis and circumferentially arranged thereabout. The mounting plate is capable of moving axially and rotating relative to the support plate to a limited range, thereby facilitating the lateral deflection of the wheel assembly in response to the engagement with the vehicle causing the wheel shaft axis to deviate a limited amount from the vertical orientation. The elastic members are radially spaced from and circumferentially arranged about the shaft axis.
