초록

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 p...
