All-wheel drive farm tractor

摘要

In an all-wheel drive farm tractor, the front axle differential (6) and rear axle differential (15) of which off the road are permanently driven by output shafts (2 and 3) of a gearbox (1), so that a rigid connection exists between front and rear axle, it is intended to compensate for the higher speeds of the front axle (7) which occur when cornering. It is furthermore intended that a device for adjustment of the axle speeds be incorporatable into the farm tractor without significant structural modifications. For this purpose a clutch (16) is arranged between ring gear (12) and differential cage (14) of the rear axle differential (15), which clutch is designed as controlled slipping coupling and the slip condition of which is controlled as a function of the size of the turning circle radius to be travelled through and/or the tractive power demand. <IMAGE>
