動車の自動変速装置。 The left and right sides each have a swash plate pump and a motor, and when the engine speed drops by a predetermined value or more from the set speed, the hydraulic pressure automatically changes the swash plate angle of the swash plate pump to the neutral side and shifts gears. In an automatic transmission for a drive vehicle, a target swash plate angle is stored in advance in a storage device, and when the engine speed decreases by a predetermined value or more from the set rotation speed, the swash plate angle of the swash plate pump is changed to the target swash plate angle. An automatic transmission device for a hydraulically driven vehicle characterized by the following settings.
