ABSTRACT:
A hydromechanical transmission that can be used as a simple and efficient continuously variable transmission includes a differential mechanism for forming either a first mehanical transfer line for high speeds or a second mechanical transfer line for low speeds, a hydraulic power transmission mechanism having a hydraulic pump/motor, and a mode selector mechanism for selecting either a low-speed mode or a high-speed mode. In the low-speed mode, the output is connected to the input via the second mechanical transfer line. In the high-speed mode, the output is connected to the input via the first mechanical transfer line. One of the hydraulic pump/motors has a fixed displacement , while the other hydraulic pump/motor has a variable displacement.
