Hydraulic stepless transmission |
摘要 |
A hydraulic stepless transmission having increased layout freedom and a compact structure with the functions of conventional hydraulic stepless transmission retained and having increased easiness of production. In the hydraulic stepless transmission, the movable swash plate (input side swash plate) of a variable displacement plunger hydraulic pump or motor is tilted by a hydraulic servo mechanism. The hydraulic servo mechanism has a power piston connected to one end of the input side swash plate for tilting the swash plate, a servo spool (13) placed normal to the direction of sliding of the power piston and substantially parallel to the input side swash plate, and a feedback link for connecting the servo spool and the input side swash plate. |
