摘要： A modular hydrostatic transaxle includes an axle module removably connected to a hydrostatic transmission module. The axle module includes a differential connected to a reduction gear train and disposed in an axle casing. A pair of axles are connected to the differential and supported within the axle casing. The hydrostatic transmission module comprises a transmission casing separate from the axle casing and hydraulically connected pump and motor disposed in the transmission casing. The motor output connection includes a shaft piloted to an input drive of the reduction gear train, which constitutes the alignment mechanism of the transmission and axle modules. The pump and motor cylinder barrels are hydraulically connected through the pump and motor block at 90° orientation, and a portion of the pump and motor block forms an inclined surface which supports a face of a thrust bearing. At least one homogeneous low friction bearing strip is confined between the swash plate and the interior portion of the casing. A disconnect mechanism includes a spring that urges a sleeve to engage the output and input shafts. The brake disc is disposed on a distal end of the output shaft and a brake cover is fastened to the outer portion of the axle casing and substantially encloses the brake disc.

摘要： In order to damp the vibrations in a hydraulic branch of a power distribution transmission, the hydraulic pump (1) and the hydraulic motor (3) which are interconnected are non-rotatably but elastically maintained in the transmission housing in the area of their connecting point by damping elements (5). The input shaft (11) of the hydraulic pump (1) and the output shaft (18) of the hydraulic motor (3) are connected with shafts (12, 17) which on their engagements have crowned teeth or spiral gearings and are floatingly mounted. It is hereby obtained that the hydraulic branch is easy to mount, can freely move and the vibrations it produces are not transmitted to the transmission housing (7) or to the toothed wheels (13, 16) of the mechanical distribution branch.

摘要： The output speed of a hydrostatic unit in a transmission is determined using a pair of variable reluctance sensors, one on a gear driven by the hydrostatic unit output and the other on the carrier of the planetary system. One of the two sensors will always be measuring a relatively high speed from which the hydro output is directly determined or indirectly determined using the current engine speed. Thus the frequency of the speed sensor used to determine the hydrostatic unit output speed is not decreased at slow hydrostatic unit output speeds.
