Abstract: A transmission for speed changing and steering of a vehicle comprises a first HST and a first differential for speed changing and a second HST and a second differential for steering. The first HST is a combination of a hydraulic pump and motor. The pump is driven by an engine and the motor is drivingly changeable by operation of a speed change pedal.

The second pump is driven by output power from the first HST and the second motor is drivingly changeable by operation of a steering wheel. A pair of second differential output shafts are rotated in opposite directions by output power of the motor, so that when turning, the first differential output shaft on the opposite side of the turning direction is accelerated.

Abstract: 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.

Abstract: The invention includes a working vehicle having a prime mover for horizontally outputting power to an axle driving system housing a transmission and a vertically projecting speed change input shaft. A gear box is detachably disposed at an upper portion of a housing of the axle driving system for transmitting power from the engine into the axle driving system. The gear box has an input shaft horizontally projecting therefrom and bevel gears such that the power transmitted horizontally from the engine changes direction in the gear box so that the power can be transmitted to the vertically disposed speed change input shaft of the transmission, which, in turn, drive the axles of the vehicle.

Abstract: A transaxle assembly for small-scaled, self-propelled machines of a relatively simple structure includes an axle-locking mechanism which is housed in an axle casing (19). The locking mechanism comprises left and right rotors (47L, 47R), each having teeth (47a) thereon and mounted fixedly on left and right wheel axles (20L, 20R), and left and right locking members (49L, 49R) each having at least one pawl (49a) engageable with the teeth. The locking members are mounted on a control shaft (50), which extends parallel to the wheel axles, such that these members are moved rotationally by a rotational displacement of the control shaft so as to cause locking engagement between the pawls and teeth. A torque spring (53) is preferably employed for causing lock-operating movement of the locking member by the control shaft. The transaxle and locking mechanism can be handled as a unit in a self-propelled machine so that assembling of the machine is made easier.
