FIELD: agricultural engineering. ^ SUBSTANCE: according to proposed method, additional traction wheels are driven by redistributing power flow from axle-shafts of rear axle. Setting of additional wheels in operating position and retraction them into bays on rear wheel disks for traveling is carried out by shifting of rear wheels along axle shafts caused by cross component of reaction of support surface appearing at turning of rear wheel relative longitudinal axis of tractor in process of translational motion, without breaking kinematical connection in transmission. Device for setting additional traction wheels in operating position and retracting them into bays on tractor rear wheel disks is made in from of turnable side reduction units, each being formed by two articulated levers. Joint is formed by two cylinders telescopically interconnected and displaced relative to each other along screw guide. ^ EFFECT: enlarged functional capabilities and operation adaptability of wheeler tractor. ^ 3 cl, 7 dwg |
