DEVICE FOR GAIN need to strengthen the leg for powered CLUTCH

摘要

An apparatus for enhancing the required force legs for actuating the clutch includes: a housing (22) in which is formed a hydraulic chamber (80), which when exposed to foot on the clutch pedal by a cylinder sensor is supplied incompressible medium, wherein the hydraulic chamber (80) movable along the longitudinal axis (a) arranged piston rod (40), a control region (84) which has a stepped bore (86) which through the passage (82) connected to the hydraulic chamber (80) to a stepped bore (86) the control piston (8) which by supplying pressure on the one side by flowing through a passage in the stepped bore (86) under the action of a foot on the clutch pedal incompressible medium pressure is movable in the feeding direction from the initial position to the final position. A stepped bore (86) has a portion (86e) of the opening, through which channel (94) connected to the primary chamber (98a) amplifying the cylinder (30) which is movably located amplifying piston (42). When the control piston (8) is in its final position, a portion (86e) of the opening is connected to the input of a compressible medium, whereas the connection section (86e) of the opening in a yield of compressible medium is interrupted. At the end of the piston rod (40) in the amplification cylinder (30) is arranged extending along the longitudinal axis (A) the pusher (48) for actuating the clutch. The piston (42) rigidly fixed to the piston rod (40) and plunger (48) fixed to the end of the piston rod (40) rotatably about the longitudinal axis (A).
