ABSTRACT:
A hydrostatic/mechanical transmission system for motor vehicles having an engine coupled with a multi-speed mechanical transmission and a hydrostatic transmission including an accessory drive connectable to activate a variable displacement hydropump that is hydraulically connected with hydromotor; wherein, in one mode of operation, the hydrostatic transmission is operated, with the mechanical transmission in neutral, and the hydromotor drives the vehicle by way of a stepdown gear, wherein the stepdown gear drive is a multistep power transmission and wherein when in the one mode, the hydromotor drives a secondary gear shaft of the multi-speed transmission, the connection of this one mode being possible only in the neutral position of the multi-speed transmission.
