摘要 |
The invention relates to a continuously variable transmission (1), in particular for motor vehicles, provided with an adjustable pulley assembly (7) comprising two sheaves (8, 9) on a pulley shaft (6). At least one sheave (8) is axially movable with respect to the pulley shaft (6) by means of hydraulically operated movement means. The movement means comprise a piston/cylinder assembly (22; 26, 27, 29) for generating a first force acting on the movable sheave (8) and centrifugal pressure compensating means for generating a second force acting on the movable sheave (8) in a direction opposite with respect to said first force. Said centrifugal pressure compensating means comprise a further cylinder (33, 33'), fixed to the axially movable sheave (8) in radial direction beyond the piston/cylinder assembly (22; 26, 27, 29), and a further piston (32), fixed to the pulley shaft (6). The further piston (32) and the further cylinder (33, 33') form a further piston/cylinder assembly. (30, 32, 33, 33') <IMAGE>
