| 摘要 |
<p>The invention relates to a simplified and reliable hydraulic-variator transmission for transport machines ensuring smooth and stepless alteration of the traction force and speed of the transport machine and changing the direction of its motion. A primary motor (1) is mechanically connected to a pump (5), which is coupled to a hydraulic distributor (6) connected to a hydraulic motor (7) which is mechanically coupled to a driving unit (2) of a belt variator (19), the driving unit (3) of which is mechanically connected to one or several driven wheels (8). The driving unit (2) comprises a fixed (17) and mobile (14) belt pulley. The driven unit (3) contains a fixed (18) and a mobile (15) belt pulley. The mobile belt pulley (14) is in constant contact with spring (13), and the mobile belt pulley (15) is mechanically coupled to one or several hydraulic cylinders (4), which, on their turn, are connected by pipelines (9) to pump (5). 1 claim, 1 figure</p> |
