VEHICLES WASHING MACHINE WITH ROTATING WASHING FLUID DISPENSING BAR AND OSCILLATING NOZZLES

Vehicles washing machine, in particular cars or the like, comprising at least one gantry on which a dispensing bar of at least one washing fluid is mounted, with at least one crossbar supporting at least one dispensing nozzle and that is rotatably mounted around an axis coincident with and/or parallel to its longitudinal axis, being provided at least one motorised rotary drive unit of said crossbar wherein said at least one nozzle is mounted on said crossbar with its jet propagation axis oriented transversely to the longitudinal axis of said crossbar and is fixed to said crossbar in an oscillating manner around an axis perpendicular to a plane parallel to said crossbar longitudinal axis or containing said axis of fluid propagation, being provided a gear reducer member for driving said oscillating motion of said nozzle. According to the invention, said gear reducer member for driving said oscillatory motion of said at least one nozzle is assembled on a support terminal of the crossbar which is stationary and is provided in correspondence with at least one end of said crossbar while said gear reducer member is connected to a slider-crank transmission mechanism, said crank controls a mechanism comprising at least one oscillating plate supporting at least one nozzle, said connecting rod being provided with its longitudinal axis coinciding with the axis of rotation of said crossbar and being connected to at least one control arm of said at least one oscillating plate by means of a ball joint.
