Friction clutch for use in motor vehicle, has drive pawl and pressure plate including stopper unit, which limits movement of pawl in direction of clutch housing, where pawl is fastened at plate and supported at biasing spring metal sheet

摘要

#CMT# #/CMT# The clutch (1) has a ramp ring (8) forming a ramp device with a pressure plate (4). The ramp device changes an axial distance of a contact region between the plate and disk spring (6) by rotating the ring in a circumferential direction relative to the plate using a spindle device (11). The spindle device is driven by a pinion (12), which is engaged with a drive pawl (13) i.e. spring part. The pawl is fastened at the plate and supported at a biasing spring metal sheet (21). The pawl and the plate include a stopper unit, which limits a movement of the pawl in a direction of a clutch housing (3). #CMT#USE : #/CMT# Friction clutch for use in a motor vehicle. #CMT#ADVANTAGE : #/CMT# The clutch is designed such that the drive pawl has an optimal contact to the pinion. The clutch allows the pawl to be contacted with the biasing spring metal sheet during mounting the clutch housing and the pressure plate, thus avoiding risk of damage of the drive pawl, the pinion or a readjusting drive during mounting the clutch housing and a pressing plate. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial sectional view of a friction clutch. 1 : Friction clutch 3 : Clutch housing 4 : Pressure plate 6 : Disk spring 8 : Ramp ring 11 : Spindle device 12 : Pinion 13 : Drive pawl 21 : Biasing spring metal sheet.
