摘要： A variable capacity pump and two variable capacity motors are connected in a closed circuit. First to fourth drive gears are fitted to motor shafts of the variable capacity motors via clutches. A first driven gear, which meshes with the first and third drive gears, and a second driven gear which meshes with the second and fourth drive gears are fitted to an output shaft. Equivalent capacities of the variable capacity motors are made different. Control is exerted such that the capacities are decreased to zero in order of equivalent capacities. To decrease the capacity of each variable capacity motor, the gear change ratio of the variable capacity motor the capacity of which has decreased to zero is changed to decrease the equivalent capacity and, at the same time, the capacity is increased to maximum. This increases the gear change ratio for the continuously variable transmission and controls acceleration.

摘要： The present invention relates to a method of controlling a speed change of a hydraulic driving apparatus for a vehicle and to a speed changing device which provide excellent traveling efficiency and controllability. To this end, the method of controlling a speed change comprises discriminating between at least a powering travel and a braking travel from an accelerating amount (.theta.) and rotational speed of a hydraulic motor (50) for controlling. At the time of the powering travel, a directional control valve (21) can be fully opened in response to the rotational speed (.omega.out) of the hydraulic motor (50) and the accelerating amount (.theta.). In addition, the speed changing device comprises an accelerating amount detection sensor (61a), a motor rotational speed sensor (52) for detecting a vehicle speed (V), and a control device (60) for discriminating, from the accelerating amount (.theta.) and the vehicle speed (V), between the powering travel and the braking travel for providing a control.
