Hydrostatic-mechanical transmission arrangement for motor vehicles having following features : - a prime mover (1) is connected to a selector transmission (4) ; - a shiftable power take off (11, 14) drives a variable hydropump (35) which is hydraulically connected to a hydromotor (25) ; - the hydromotor (25) drives an output shaft (16) attached to the selector transmission (4) and connected by an axle drive, doing so via a selectable reduction gear (17) in order to operate a creeper drive and is characterised by the following features : - the reduction gear is a multiple-stage powershift transmission (intermediate gearbox 17) and - the creeper gear drive can only be engaged when the selector transmission (4) is in neutral. |
