CENTRAL REDUCTION GEAR OF WHEELED VEHICLE Russian patent published in 2010 - IPC B62D7/04 B62D39/00 B62D63/02 

FIELD: transport.

SUBSTANCE: wheeled vehicle comprises wheel platform q with four wheel pairs 2, rotary body 3, turret 4 with stabiliser, support rollers 5, engine with clutch and gearbox 6, central reduction gear 13, transmission, steering drive, two mechanisms allowing running in two tracks, brakes and wheels dampers. Body 3 turns about central vertical axis 8 of wheel platform 1, driven by steering wheel 9 with shaft via chain gear 10 and screw reducer 11 to bevel gear 12 of central reduction gear 13. Wheel pairs 2 turn in the same direction and through the same angle driven by lower bevel gear 15 in permanent mesh with running gear 12. Lower bevel gear 15 is coupled by tube 16 with drive sprockets 17 and 19 of two chain gears 18 that transfer rotation to driven sprockets 20 to turn wheel pairs 2. Brake hydraulic system working fluid is fed from braking fluid tank and main braking cylinder to central transfer unit via pipelines, and, further, via hole into special channel of central vertical axle 8, wherefrom is comes via for distribution unions into wheel braking cylinders. Turret 4 is stabilised thanks to toothed coupling 33 that stays in engagement with helical gear 14 rigidly coupled by central vertical axle 8 with housing of wheel platform 1. Drive toothed half-coupling is rigidly coupled with upper bevel gear 14, while drive half-coupling is fitted on shaft 35 rigidly coupled with turret 4 and has two fixed positions: lower I - stabilisation ON position, upper II - stabilisation OFF position.

EFFECT: simplified turret control and stabilisation control and drive mechanism.
