| 摘要 |
The present invention relates to a friction-type coupling arrangement comprising a fluid actuated pressure means (16) which when activated actuates a pressure plate (28) for pressing together the discs of a driving coupling part (10, 15) and a driven coupling part (9, 14). According to the invention, the pressure plate (28) actuates the pressure means (16) through the medium of a force-amplifying lever means (26) that has a relatively long lever arm (26b) connected to the pressure means (16) and a shorter lever arm (26a) connected to the driven coupling part (9). |
