A hydraulic module with two inclined-axis drive systems. The hydraulic module comprises a yoke () which, by virtue of a pin () that is in active connection with a piston (), is pivoted about a horizontal pivot axis () so as to adjust the stroke volume of the two inclined-axis drive systems.

Hydraulic module

A hydrostatic-mechanical transmission having a radial piston motor () with a crankshaft () which drives a spur gear (). A transmission housing comprises three housing portions which define two separate spaces. The spur gear arrangement is located in one of the spaces while the radial piston motor is located in the other space.

Hydrostatic-mechanical transmission

A hydrostatic-mechanical transmission with a radial piston motor () which has a crankshaft () that drives a spur gear () and the crankshaft () is rotatably mounted at three bearing points ().
