  • Patent number: 6647720
    Abstract: A hydrostatic unit for a hydro-mechanical torque division transmission for a work vehicle having a mounting frame (10, 12) in which the shafts (18, 20) of hydrostatic devices (22, 24) are arranged parallel to one another are supported by bearing units (14, 16, 42, 48). The mounting frame (10, 12), the hydrostatic units (22, 24), the input shaft (36), the output shafts (44, 50, 56, 64) and the bearing units (14, 16, 42, 48, 54) together form a functioning hydrostatic module which can be pre-assembled. By supporting an input shaft (36) of the hydrostatic unit on the mounting frame (10, 12) by a bearing unit (38) such that it can rotate and is connected to the shaft (18) of the pump (22), a hydrostatic unit is provided that can be used in many different transmission applications.

  • Patent number: 6592485
    Abstract: A transmission assembly with an infinitely variable transmission component and a constant transmission component wherein the components are designed as modular units. The variable transmission module forms a self-contained functional transmission unit with a variable transmission housing, open on at least one side where it contains a flange. Within the flange area extends at least one infinitely variable output shaft of the variable transmission module. The flange allows the attachment of one constant transmission module of a plurality of modules of different power categories as desired.

  • Patent number: 5695422
    Abstract: A hydrostatic-mechanical infinitely variable transmission for a vehicle includes a hydrostatic unit and a mechanical unit. The mechanical unit is a planetary drum and includes a planetary summation gearing and further planetary transmission gearings. The planetary drum has an input shaft and an output shaft which are concentric to the engine output shaft. The axis of the hydrostatic unit is parallel to and lower than the axis of the planetary drum so that the rotating parts of the planetary drum are above the level of oil in the transmission sump. The sealed hydrostatic unit is immersed in the oil of the sump and cooled thereby The output shaft of the transmission is parallel to the axis of the planetary drum. The output of the planetary drum is coupled to the transmission output shaft by a gear train. This makes it possible to adjust the spacing and the transmission ratio between the planetary drum output and the transmission output shaft as desired.
