Coining.Here, especially generating rill in first end face in steel carrier.As optinal plan furthermore, it is molded so-called
Macro-texture, such as waffle-like pattern or the like.Such macro-texture is deep by the texture within the scope of 0.05 to 0.9mm
Degree, that is the depth restriction by axially being measured from highest point to minimum point.
The present invention also realizes a kind of diaphragm clutch, is arranged alternately with internal diaphragm and with the inside diaphragm
External diaphragm, wherein internal diaphragm or external diaphragm are configured to friction plate according to the present invention, and other friction plates composition is matched
Close diaphragm.
Matching film plate, more specifically whole matching film plates are steel membrane of the two sides without coating according to first embodiment
Piece, so that steel also constitutes rubbing surface on two sides.
If matching film plate two sides without coating, friction plate according to the present invention set direction be arbitrarily, because
And only first end face is directed toward identical axial direction in some friction plates and some in friction plate according to the present invention rub
Pad refers in the opposite direction.The outstanding place of such diaphragm clutch be that the response time is short, torque capacity is high and
Assembly is simple.
As optinal plan furthermore, matching film plate is the diaphragm of one-sided coatings in this second embodiment.In this feelings
In condition, whole matching film plates and oriented in the same manner in the axial direction all according to friction plate of the invention with that side of its coating,
Thus when diaphragm clutch closure, the end face for being provided with friction material rests on the not set friction material of the friction plate adjoined
On the end face of material.
As optional, matching film plate is also possible to friction plate according to the present invention.
