CAR WASHER WORKING MEMBER Russian patent published in 1994 - IPC

FIELD: car servicing equipment. SUBSTANCE: working member has drive vertical rotary brushes which are mounted on swingable cantilevers. Each brush has an axial positioning mechanism. The mechanism is made in the form of coaxially positioned drive and driven gears 12 and 13 respectively and intermediate bevel gear 15. The teeth of the drive and driven gears are made on a wavy pitch surface. Means for translational movement of the intermediate gear along the axis of brush shaft 5 has slider 16, carrier 18 and a worm gearing with controllable worm 20. The slider is positioned on a carrier. The carrier is mounted for rotation around the brush shaft and fixing by worm wheel 19. The law of cyclic axial movement of the brush is related to the shape of the wavy pitch surface of intermediate gear 15 and drive and driven gears 12 and 13 engageable with it. EFFECT: improved washing quality. 3 dwg
