ABSTRACT:
A transmission with a static, hydraulic continuously-variable-speed transmission mechanism comprising a hydraulic circuit having a closed circuit, a hydraulic pump connected on the crankshaft of an engine, and a hydraulic motor having a motor output shaft coaxial with the axis of rotation of the hydraulic pump, and contained in a casing with its axis extended in parallel to that of the crankshaft. The static, hydraulic continuously-variable-speed transmission mechanism has a small construction and has an increased degree of freedom of selection of speed change ratio. An output shaft, i.e., the final output shaft of a transmission is supported for rotation on a casing with its axis extended in parallel to that of a static, hydraulic continuously-variable-speed transmission mechanism. A motor output shaft and the output shaft can be interlocked by a reduction mechanism.
