Abstract
The clutch cover assembly comprises a clutch cover, a pressure plate, a washer-type spring and a lever member. The clutch cover is fixed to a flywheel. The pressure plate is located within said clutch cover and is fashioned with a pressing surface for clamping facings against the flywheel. The washer-type spring engages the pressure plate to the flywheel. The lever member, supported by the clutch cover, is for engaging the pressure plate in combination with the washer-type spring to the flywheel and for releasing engaging loads of the washer-type spring from the pressure plate.
Claims14
A clutch cover assembly comprising:
- a clutch cover fixed to an input rotation member;
- an annular pressure plate located within said clutch cover, formed with a lateral friction surface for clamping a friction member to said input rotation member, and formed with a protruding element on an opposite lateral side;
- an elastic member for applying an engaging load on said pressure plate radially spaced apart distance from said protruding element, said elastic member applying an engaging load on said pressure plate such that said elastic member and a diaphragm spring act on said pressure plate in series, said diaphragm spring pivotable about said protruding element, whereby a resultant combined load from said elastic member and said diaphragm spring provides an allowable deflection larger than a load of said diaphragm spring alone;
- and
- said diaphragm spring is supported by said clutch cover for engaging said pressure plate with said input member in conjunction with said elastic member and for releasing said engaging load of said elastic member from said pressure plate.

A clutch cover assembly, comprising:
- a clutch cover attachable to an input rotation member;
- an annular pressure plate disposed within said clutch cover formed with a friction surface for clamping a clutch disk between said annular pressure plate and said input rotation member, said annular pressure plate further formed with an annular protruding element on a side opposite said friction surface;
- a diaphragm spring disposed within said clutch cover, a portion of said diaphragm spring engaging said protruding element;
- and
- a conical spring supported by said clutch cover, said conical spring applying an engaging load to said diaphragm spring at a position that is radially spaced apart distance from said protruding element.

A clutch cover assembly comprising:
- a clutch cover attachable to an input rotation member;
- an annular pressure plate disposed within said clutch cover formed with a lateral friction surface for clamping a clutch disk between said annular pressure plate and said input rotation member, said annular pressure plate further formed with a protruding element on a side opposite said lateral friction surface;
- a diaphragm spring disposed within said clutch cover, a radial mid-portion of said diaphragm spring engaging said protruding element;
- a first ring member disposed within said clutch cover;
- a second ring member engaging a radial outer portion of said diaphragm spring;
- and
- a conical spring disposed within said clutch cover having a radial outer portion engaging said first ring member such that said first ring member is confined between said clutch cover and said conical spring and an outer radial portion engaging said second ring member such that said second ring member is confined between said conical spring and said diaphragm spring, said conical spring applying an engaging load on an outer radial portion of said diaphragm spring such that said conical spring and a diaphragm spring act on said annular pressure plate in series.

A clutch cover assembly, comprising:
- a clutch cover attachable to an input rotation member;
- an annular pressure plate disposed within said clutch cover formed with a friction surface for clamping a clutch disk between said annular pressure plate and said input rotation member, said annular pressure plate further formed with an annular protruding element on a side opposite said friction surface;
- a diaphragm spring disposed within said clutch cover, a portion of said diaphragm spring engaging said protruding element;
- a conical spring supported by said clutch cover, said conical spring applying an engaging load to said diaphragm spring at a position that is radially spaced apart distance from said protruding element;
- and
- wherein said diaphragm spring is pulled axially away from said input rotation member for disengagement of said annular pressure plate from said clutch disk.
