ABSTRACT:
A hydromechanical drive system having a swash-plate type hydrostatic axial piston engine and a mechanical transmission including a connection plate having a control surface. The axial piston engine includes an outer housing and a cylindrical drum with working cylinders located within the outer housing. Hydraulic-medium channels are formed in the connection plate which open onto the control surface and the working cylinders are periodically connected with the hydraulic-medium channels during rotation of the cylindrical drum. A gear element is located on the connection plate.
