VEHICLE WHEEL GAUGE CHANGING DEVICE Russian patent published in 1999 - IPC

FIELD: transport engineering. SUBSTANCE: device has splined bushing I, with splines on outer surface, rigidly mounted on axle-shaft 2, hub 4 with splines on inner surface to engage with splines of bushing 1, and hydraulic cylinders 6 mounted on rear axle sleeves. Rods of cylinders are connected with hub 4 through bearing unit 7. Hydraulic cylinders 6 are connected to standard hydraulic system of tractor through oil pipeline. To prevent slipping of hub 4 from splined bushing 1 at maximum wheel gauge, lockwasher 8 is used. protective casing 9 prevents getting of mud into bearing unit.
