METHOD AND DEVICE FOR TRANSMISSION OF POWER IN CLOSED DIFFERENTIAL MECHANISM Russian patent published in 1998 - IPC

FIELD: mechanical drives with closed differential mechanisms. SUBSTANCE: transmission of power in closed differential mechanism is effected in two parallel flows; power is taken off intermediate shaft of back coupling. Back coupling consists of intermediate shaft and gear wheel is used for closing the driven members of differential mechanism. One driven member of differential mechanism is chosen to be drive member and other driven member is chosen to be driven member in closing back coupling. Chain being closed belongs to differential mechanism. Product of ratios one of which is ratio of closing back coupling and other is ratio of closing chain with drive member of differential mechanism stopped is chosen to be positive and equal to one. Relationship between ratio at stopped driven member of closing back coupling of revolutions of drive member of closing back coupling to revolutions of drive member of closing back coupling and ratio at stopped drive member of closing back coupling of revolutions of drive member of differential mechanism to revolutions of driven member of closing back coupling is chosen to be negative and equal to ratio at stopped drive member of differential mechanism of revolutions of driven member of closing back coupling to revolutions of drive member of closing back coupling. Axes of central wheels are shifted relative to each other. EFFECT: enhanced efficiency of closed differential mechanism. 3 cl, 2 dwg
