Abstract: A hydrostatic drive system for vehicles may have a hydrostatic transmission unit with a hydraulic motor provided with a containment body and a drive shaft rotationally supported around a primary axis inside of the containment body. The system may also have an axle with a housing case for a differential device for the transmission of the drive torque to two half-axles and rotating around a secondary axis transverse to the primary axis. The differential device may also have a toothed conical drive ring gear in rotation about the secondary axis. The coupling member may be a conical pinion rigidly associated in rotation about the primary axis with the drive shaft and directly geared with the ring gear, the pinion being positioned along the terminal section of the drive shaft.

Abstract: A swash plate bearing is disclosed. The swash plate bearing may have an arcuate cage member having at least one flange and a plurality of rolling elements rotatably coupled to the at least one flange. A coupling seat extends laterally from the at least one flange, the coupling seat may have an insertion hole. A link member may be rotatably coupled to the cage member, the link member having a central portion positioned between a first terminal portion and a second terminal portion. A first stem connects the central portion to the first terminal portion and a second stem connects the central portion to the second terminal portion. The central portion is positioned in the insertion hole.
