DRIVE APPARATUS FOR ROBOT-VACUUM CLEANER Russian patent published in 2006 - IPC A47L9/28 

FIELD: robot engineering, in particular, automatic cleaning equipment.

SUBSTANCE: drive apparatus has housing of robot-vacuum cleaner and two electric engines mounted within housing of robot-vacuum cleaner, said electric engines being driven from respective power sources. Drive apparatus includes two drive wheels driven for rotation through two electric engines, two driven wheels following two drive wheels, and motive force transmission means urging drive wheels and driven wheels to move in conjunction. Apparatus is further equipped with assembled case member located within housing of robot-vacuum cleaner and adapted for supporting two drive wheels and two driven wheels, and shock-absorbing device located in assembled case member and adapted for absorbing impacts occurring in case of action from surface subjected to cleaning.

EFFECT: smooth movement through obstacle, such as carpet or door threshold, and zone subjected to cleaning without creation of noise, and elimination of probable impacts during movement through obstacle.
