摘要： An improved diagnostic system for a hydrostatic apparatus such as a hydrostatic transmission or transaxle is disclosed. A fastener having a port formed therein is used to connect a hydraulic component such as a center section to a housing. A diagnostic system may be located external to the housing and connected to the hydraulic circuit at least partially through the fastener port. A relief valve may also be located in the fastener and connected to the fastener port, or in a different fastener having a separate fastener port, to permit the fluid in the hydraulic circuit to be discharged to a sump.

摘要： An axle driving apparatus for being mounted on the body frame of a vehicle and for independently rotating drive wheel members. The axle driving apparatus includes a first axle driving unit (18L) having a housing (40) and a single axle (20L), the single axle (20L) defining a proximal end portion rotatably mounted in the housing (40) and a distal end portion extending outwardly from a first side of the housing (40). An enlarged region is defined by the housing (40), with the enlarged region extending substantially perpendicular to the longitudinal axis of the single axle (20L). A hydraulic stepless speed change assembly (22) is disposed within the enlarged region. The speed change assembly (22) includes a hydraulic pump (52) having an input shaft (21) projecting from the enlarged region and includes a hydraulic motor (55) including an output shaft (74) drivingly connected to the single axle (20L). The first axle driving unit (18L) is used in conjunction with a second axle driving unit (18R) which is adjacently disposed to the first axle driving unit (18L) on the body frame of the vehicle and which is of substantially similar construction. However, the second axle driving unit (18R) features a single axle (20R) which extends outwardly from a second, opposite side of the housing (40) such that the axles (20L, 20R) are oppositely disposed.

摘要： An axle driving apparatus comprises: a common housing; a pair of coaxial axles disposed in the housing; a common input shaft for receiving power from a prime mover, the common input shaft being extended perpendicular to the axles in the housing and passed through a gap between the axles; and a pair of stepless transmissions sharing power from the common input shaft, and transmitting power to the respective axles. The pair of stepless transmissions are arranged in the housing symmetrically centered on an axis of the common input shaft. The axle driving apparatus further comprises: a PTO shaft disposed coaxially to the common input shaft; a clutch disposed in the housing and interposed between the common input shaft and the PTO shaft; and a brake which is applied simultaneously to disengagement of said clutch so as to prevent inertial rotation of said PTO shaft.

摘要： An axle driving apparatus comprises a housing. The housing contains a hydrostatic transmission, a differential unit driven by the hydrostatic transmission, a pair of axles mutually differentially connected through the differential unit, and a restricting mechanism for selectively restricting differential motion of the axles by manual operation. The differential unit comprises a ring gear serving as an input gear and a pair of bevel gears which can be differentially rotated by rotation of the ring gear. The restricting mechanism engages one of the bevel gears with the ring gear. If a pair of differential side gears fixed on the respective axles serve as the bevel gears, the restricting mechanism engages one of the bevel gear to the ring gear through a claw clutch or a friction clutch.

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.
