摘要： 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. Output power from the motor is transmitted into a pair of first differential output shafts as axles through the first differential. The second HST is a combination of a hydraulic pump and motor. 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.

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： A driving apparatus for speed changing and steering of a vehicle consists of a first driving unit for speed changing in advancing and reversing and a second driving unit for steering, which are arranged in a longitudinal row and are attached to a vehicle chassis. Each of the first driving unit and the second driving unit has a common structure, which comprises a housing and an HST and left and right differential output shafts contained in the housing. A left first differential output shaft and a left second differential output shaft are connected with each other so as to be rotated in the same direction, and a right first differential output shaft and a right second differential output shaft are connected with each other so as to be rotated in opposite directions. Both first and second HSTs of the first driving unit and a second driving unit receives power from engine through a common single belt. A movable swash plate of a hydraulic pump of the first HST is connected to a speed change pedal and a movable swash plate of a hydraulic pump of the second HST is connected to a steering wheel.
