摘要： An improved differential unit (101) for an integrated hydrostatic transmission (IHT) is provided. The differential unit comprises an input gear (200), a cross-shaft (202) disposed within a central opening of the input gear, and a pair of clutch members (204L,204R) disposed coaxial with the input gear. One of each clutch member is disposed on opposite sides of the cross-shaft. A first plurality of friction members (208) extend from each clutch member. The differential unit also comprises a pair of side couplings (210L,210R), each coaxially disposed within one of the clutch members, and a second plurality of friction members (212) extending from each side coupling. Each clutch member includes a cam surface (206) that comes in contact with the cross-shaft when the differential unit is under normal operating conditions. Alternative embodiments are also described herein.
摘要翻译：提供了一种用于集成静液压传动（IHT）的改进的差速单元（101）。差速单元包括输入齿轮（200），设置在输入齿轮的中心开口内的横轴（202）和与输入齿轮同轴设置的一对离合器构件（204L，204R）。每个离合器构件中的一个设置在横向轴的相对侧上。第一多个摩擦构件（208）从每个离合器构件延伸。差速单元还包括一对侧联接器（210L，210R），每个侧联接器同轴地设置在一个离合器构件内，以及第二多个摩擦构件（212），其从每个侧联接件延伸。每个离合器构件包括当差动单元处于正常操作条件时与横轴接触的凸轮表面（206）。本文还描述了替代实施例。

摘要： An axle driving apparatus consisting of a housing (1, 2) for compactly housing inner portions of axles (7), a hydrostatic transmission, and a transmitting mechanism for transmitting power to the axles from an output shaft (4) of the hydrostatic transmission. The housing is partitioned by an internal wall (8) into a chamber (R1) containing the hydrostatic transmission and a chamber (R2) containing the other transmitting mechanisms. The housing is filled with oil in common with both chambers. A trunnion (35L, 35R) for changing the output rotation of the hydrostatic transmission is disposed in parallel to the axles. A shock absorber (73) is provided to prevent abrupt speed change. A differential locking device (84, 85, 86) is attached to the differential gear to thereby improve the straightforward running capacity of the vehicle.

摘要： An axle driving unit having a housing (21, 22) for supporting a first axle (17) for mounting thereon a first driving wheel (3L), and a longer second axle (18) for mounting thereon a second driving wheel (3R). The axle driving unit is eccentrically mounted on a body frame (1) in proximity to the first driving wheel (3L). A speed change transmission (T) is disposed in an enlarged region of the housing that extends substantially perpendicularly with respect to the axles (17, 18). The axle driving unit can thus be easily disposed to the side of a chute (6) of a rear-discharge type lawn tractor.

摘要： An axle driving apparatus includes a first axle driving unit (18L) having a housing (40) and a single axle (20L). 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 is disposed in the enlarged region. The speed change assembly 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). A second axle driving unit (18R) having similar construction is adjacently disposed to the first axle driving unit (18L). However, the second axle driving unit (18R) features a single axle (20R) being disposed on the opposite side of the single axle (20L) of the first axle driving unit (18L).
