Abstract: In a hydro-mechanical transmission having a hydrostatic unit and a mechanical gear train, the hydrostatic unit is resiliently mounted in the transmission housing to reduce the transmission of noise and vibration to the housing. Movement of the hydrostatic unit is facilitated by mounting the planetary carrier on a ball bearing instead of taper roller bearings. The ball bearing allows the carrier limited movement transverse to the axis of rotation of the carrier. To further reduce wear of the gear faces, one or more of the meshing gears at the point of relative movement have crowned gear faces rather than straight gear faces. This avoids a single line of contact of the meshing teeth at the tooth edge.

Abstract: The system is comprised of three sub-systems. The first sub-system has an actuation lever (P) which can rotate about an axis (E1) to displace excentrically the Second Sub-system with respect to the Third by a predetermined angle circumferentially about a toothed wheel (R1), a toothed fluted wheel (R2) or fluted cross or cross with sliding torkes, and gear carrying shafts passing therethrough. The grooved wheel (R2) rotates a fixed transmission relationship with respect to the rotation of the input shaft. The second sub-system transforms and divides the input power for the primary shaft into powers which are transmitted to various secondary shafts (E3, E4) characterized by oscillating angular speeds and torkes. The third sub-system composes the powers transmitted by the secondary shafts by means of a epicyclic train (T1) into an output power. The resulting output motion is proportional to the eccentricity angle of the first sub-system with respect to the third sub-system.

When none of the components are fixed, they form a two-in/one-out differential transmission.
