Abstract (en)
[origin: EP0391236A2] A drive for earth-moving machines, in particular for wheel loaders, consists of two drive axles, the differential mechanisms (6) of which are connected to one another by a cardan shaft (7, 8, 9, 16), and of an internal combustion engine (13) driving a hydraulic pump (12) which drives the cardan shaft via a controllable hydrostatic motor, preferably a swash-plate motor. In order to simplify the drive and to permit easy accessibility for maintenance purposes, the hydrostatic motor (15) drives the cardan shaft (7, 8, 9, 16) in the area between the differential mechanism (6) of the rear wheel axle and the cardan joint (9).
