US 10,626,631 B2 · Pool cleaner drive mechanism

Abstract

The invention relates to a pool cleaner. Rotation from a turbine is transmitted to a first wheel that is forwardly driven. A second wheel is switched between corresponding forward rotation and rearward rotation. An axle of the first wheel rotatably supports a sleeve that carries the second wheel. The reverse transmission is effected by a double-sided dog clutch member slidably supported between a pair of clutch gears freely rotatable on a rotating lay shaft. A first clutch gear is connected for reverse rotation and a second clutch gear for forward rotation of the sleeve. A switching mechanism includes a movably mounted lever arm engaging the double-sided clutch member with a cam follower engaging a cam formation carried on an independently supported control gear connected to the turbine and in mesh with a worm gear on the lay shaft.

Dependent claims

A pool cleaner drive mechanism comprising:

a pair of wheels supported by a chassis,
a forward first driven gear connected through an axle to a first wheel and
a second driven gear fixed to a lay shaft carrying a double-sided dog clutch member slidable between a pair of clutch gears freely rotatable on the lay shaft and providing cooperating dog clutch formations,
a first clutch gear of the pair connected for reverse rotation of an axle component carrying a second wheel and
a second clutch gear connected for forward rotation of the axle component carrying the second wheel,
with a switching mechanism connected to shift the dog clutch member between engagement with the first and second clutch gears respectively to control rotational direction of the second wheel.
