It plays the same role as the gear transmission of the device. [0002] [Prior Art] Conventionally, when power is transmitted by hydraulic pressure, the transmission speed is changed by the pump and motor itself. It is carried out by the structure of. [0003] [Problems to be solved by the device] This proposal enables a large shift change that cannot be achieved by conventional methods. To do. [0004] [Means for Solving the Problems] Now, to explain the solution, (B) A pump with a capacity that provides the necessary work for the hydraulic motor from the power source. Place the number, (B) In order to operate the hydraulic motor at the required speed and torque, the power source Control so that the number of pump operating units can be changed by connecting and disconnecting the disconnecting device installed between To do. (C) In addition, a check valve etc. is installed on the pump discharge side of the second and subsequent stages to operate the liquid. Try to prevent back flow to the pump which has not been installed. (D) The operation of the interrupting device and the check valve is Provide a circuit that operates to be (open) at the same time. The structure is as described above. [0005] [Action] If the above structure of the present proposal is used, for example, when three arranged pumps are provided, When applying maximum torque to the hydraulic motor from the power source, connect one pump and operate it. And, when giving the maximum rotation speed to the hydraulic motor, connect three pumps and operate. It In this way, it is possible to greatly change the torque and the rotation speed than the power source. [0006] 【Example】 The intermittent device that connects the power source and the pump, and the check valve are operated manually or automatically. With either type of control, the purpose can be achieved. Note that the second and third disconnecting devices are not connected. If so, the second and third pump check valves are interlocked so as to open and the flow to the hydraulic motor is increased. Although the quantity is controlled, this control can achieve the purpose not only by the electromagnetic type but also by the hydraulic type. Wear. Also, the capacity of each pump is determined by the operating conditions, The purpose of the discontinuity device can be achieved either in series or in parallel. [0007] [Effect of the device] Therefore, according to the present invention, the power transmission from the power source can be hydraulically operated by a gear type It is possible to obtain a power shift similar to that of a transmission. Therefore, many It can be used as a compact speed change device for transportation vehicles.
