摘要： In a vehicle transmission assembly which includes a hydrostatic transmission (14) and mechanical transmission mechanism (21) for driving rear wheel axles (20) of the vehicle at a variable speed, a hydraulic pump (16) and hydraulic motor (17) of the hydrostatic transmission are mounted on a plate member (30), secured to a front of a transmission casing (15), at an upper and lower locations such that only the motor is disposed within the transmission casing at a location above the mechanical transmission mechanism. The mechanical transmission mechanism includes plural transmission shafts (31, 32, 33) all extending laterally of the transmission casing and is connected drivenly to the motor. Pump shaft (18) of the hydraulic pump is adapted to drive at least one of a rear-PTO shaft (23) and mid-PTO shaft (24) through a drive shaft (41) disposed co-axially with the pump shaft, a fluid-operated PTO-clutch (42) mounted on the drive shaft, and a gear train (43; 143; 243) disposed at a rear end portion within the transmission casing. A compactness of the transmission assembly and turnability of the vehicle with a small radius of turn are assured.

摘要： A transaxle apparatus is constructed so that left and right axles, two hydrostatic transmissions (HSTs), one for driving a vehicle and the other for steering it, and a differential unit for differentially connecting said axles with each other are together contained in a housing. The driving HST is disposed so that its hydraulic pump and motor are aligned along either a left or right side of the housing. The steering HST is disposed so that its hydraulic pump and motor are aligned along either a front or rear side of the housing. The differential unit is laterally opposite to the driving HST. Either the left or right axle crosses the driving HST between its hydraulic pump and motor. The two HSTs are provided with one or two flat center sections disposed in the housing. The cylinder blocks of the hydraulic pumps and motors of the two HSTs are mounted on either a top or bottom surface of the center section or sections. Power transmission mechanisms for transmitting output power from the hydraulic motors of the two HSTs into the differential unit are disposed on an opposite side of the center section(s) as the cylinder blocks. A charge pump may be attached onto the center section, and a conduit for sending fluid discharged from the charged pump into one or both HSTs may be partly extended outside the housing so as to be cooled by the atmosphere.

摘要： A power take-off support portion, including a shaft hole and an outer side surface formed around the shaft hole, is formed on a transaxle housing. The outer side surface of the power take-off support portion is shaped to fit a power take-off casing supporting a power take-off shaft in a first direction. A power take-off casing includes a power take-off main casing member and a base casing member joined to each other. The base casing member is formed with an inner side surface and an outer side surface. The inner side surface and the outer side surface of the base casing member are shaped so that the power take-off shaft supported by the power take-off main casing member is oriented in a second direction different from the first direction when the inner side surface of the base casing member is fitted to the outer side surface of the power take-off support portion, and the outer side surface of the base casing member is fitted to the inner side surface of the power take-off main casing member.

摘要： A vehicle has an engine, an accelerator for controlling the rotary speed of the engine, an axle and a multi-speed transmission for transmitting power from the engine to the axle. The multi-speed transmission includes an odd-numbered speed drive train for an odd-numbered speed level, a first clutch for the odd-numbered speed drive train, an even-numbered speed drive train for an even-numbered speed level, and a second clutch for the even-numbered speed drive train. In correspondence to operation of the accelerator and an actual speed of the axle, either the odd-numbered speed drive train or the even-numbered speed drive train is selected so as to transmit power from the engine to the axle. A shift-up or shift-down timing between the odd-numbered speed level and the even-numbered speed level relative to variation of the actual speed of the axle is changed according to detection of a tilt angle of the vehicle or a weight of the vehicle.
