Abstract
A friction clutch having a tiltable clutch spring can be disengaged by tilting the spring with a bearing which can be moved axially to engage the tips of radially inwardly extending prongs of the spring. The bearing is movable axially by an actuator which, in turn, is movable axially and away from a support by a system of ramps and rolling elements. The ramps or the rolling elements are caused to move radially of the axis of the bearing in order to move the rolling elements or the ramps axially in a direction to cause a tilting of the spring and hence a disengagement of the clutch.
Claims39
Apparatus for changing the condition of an engageable and disengageable clutch, comprising a carrier non-rotatably connectable with a housing of a transmission;
- a bearing supported by and movable relative to said carrier longitudinally of a predetermined axis of the apparatus to thereby displace at least one mobile component of the clutch between a first position and a second position;
- a support provided on and non-rotatable connected with said carrier;
- a mobile actuator provided on said carrier between said support and said bearing;
- and means for displacing said actuator relative to said support, including at least one motion transmitting member movable substantially radially of said axis to thereby displace said actuator at least substantially in the direction of said axis.
Apparatus for changing the condition of an engageable and disengageable clutch, comprising a carrier;
- a bearing supported by and movable relative to said carrier longitudinally of a predetermined axis of the apparatus to thereby displace at least one mobile component of the clutch between a first position and a second position;
- a support on said carrier;
- a mobile actuator provided on said carrier between said support and said bearing;
- and means for displacing said actuator relative to said support, including at least two motion transmitting members rotatable about second axes at least substantially normal to and spaced apart from said predetermined axis as seen radially of said predetermined axis, said motion transmitting members being movable substantially radially of said predetermined axis to thereby displace said actuator at least substantially in the direction of said axis.
Apparatus for changing the condition of an engageable and disengageable friction clutch which is interposed between an output element of a prime mover and an input element of a transmission, comprising a carrier;
- a bearing supported by and movable relative to said carrier longitudinally of a predetermined axis of the apparatus to thereby displace at least one mobile component of the clutch between a first position and a second position;
- a support on said carrier;
- a mobile actuator provided on said carrier between said support and said bearing;
- and means for displacing said actuator relative to said support, including at least two motion transmitting members movable substantially radially of said axis to thereby displace said actuator at least substantially in the direction of said axis, said carrier being arranged to be positioned adjacent and to be supported by the transmission in the direction of said axis and said bearing being arranged to move in the direction of said axis between the transmission and the prime mover, said motion transmitting members being positioned relative to said axis and relative to each other to generate--in response to a change of the condition of the clutch--forces acting radially of said axis and neutralizing each other.
Apparatus for changing the condition of an engageable and disengageable clutch, comprising a carrier;
- a bearing supported by and movable relative to said carrier longitudinally of a predetermined axis of the apparatus to thereby displace at least one mobile component of the clutch between a first position and a second position;
- a support on said carrier;
- a mobile actuator provided on said carrier between said support and said bearing;
- and means for displacing said actuator relative to said support, including at least two motion transmitting members movable substantially radially of said axis to thereby displace said actuator at least substantially in the direction of said axis, said displacing means further comprising at least one ramp on each of said support and said actuator, said ramps being spaced apart from each other in the direction of said axis and each of said at least two motion transmitting members comprising a plurality of rolling elements rotatable about a discrete second axis which is at least substantially normal to said predetermined axis, said rolling elements including at least one first rolling element in rolling contact only with the at least one ramp on said support and at least one second rolling element in rolling contact only with the at least one ramp on said actuator.
Apparatus for changing the condition of an engageable and disengageable clutch, comprising a carrier;
- a bearing supported by and movable relative to said carrier longitudinally of a predetermined axis of the apparatus to thereby displace at least one mobile component of the clutch between a first position and a second position;
- a support on said carrier;
- a mobile actuator provided on said carrier between said support and said bearing;
- and means for displacing said actuator relative to said support, including at least one motion transmitting member movable substantially radially of said axis to thereby displace said actuator at least substantially in the direction of said axis, said at least one component being arranged to change at least one of said positions thereof as a result of wear upon the clutch;
- and means for automatically compensating for wear upon the clutch, said compensating means being arranged to be disposed in a power flow between said at least one component of the clutch and said carrier.
