ABSTRACT:
A non-step transmission comprises a housing for storing hydraulic fluid therein, a driving shaft rotatably provided in the housing, a driven shaft rotatably provided in the housing in a coaxial position with the driving shaft, a first pump case rotatably provided about the driving shaft and having a fluid intake port and a fluid discharge port, a second pump case fixed on the housing, the second pump case encasing the driven shaft and having a fluid intake port and a fluid discharge port, an opening and closing mechanism for opening and closing the fluid intake port and the fluid discharge port, and gear pump mechanisms provided within the first and second pump cases, respectively. The simply constructed non-stage transmission can efficiently transmit a large torque from the driving shaft to the driven shaft.
