Abstract
A clutch mechanism designed to be installed between an engine and a motor vehicle transmission, wherein the clutch mechanism includes at least one cooling duct arranged to make a cooling fluid circulate toward the clutch, wherein each cooling duct includes an axially extending part and at least one radially extending part, the axially extending part of each cooling duct is situated radially between a transmission shaft and an interior face of the clutch support, and at least one radially extending part of each cooling duct is situated axially between the support bearing and the output hub.
Claims22
A clutch mechanism designed to be installed between an engine and a motor vehicle transmission, the clutch mechanism comprising:
- at least one clutch rotating around an axis O;
- a control system of the at least one clutch comprising:
- a case;
- and
- at least one annular piston arranged to be displaced axially relative to the case in order to engage or disengage the at least one clutch by way of at least one transmission bearing;
- a clutch support arranged to support the at least one clutch radially by way of a support bearing, wherein the clutch support is situated in a position axially intermediate between the control system and an output hub of the clutch mechanism:
- at least one cooling duct arranged to make a cooling fluid circulate toward the at least one clutch, wherein the at least one cooling duct comprises an axially extending part and at least one radially extending part;
- wherein the axially extending part of each cooling duct is situated radially between a transmission shaft and an interior face of the clutch support, and at least one radially extending part of each cooling duct is situated axially between the support bearing and the output hub.
A clutch mechanism designed to be installed between an engine and a motor vehicle transmission, wherein the clutch mechanism comprises:
- a first clutch and a second clutch rotating around an axis;
- a control system of the clutches comprising:
- a case;
- and
- a first annular piston and a second annular piston arranged to be displaced axially relative to the case in order to engage or disengage respectively the first clutch and the second clutch by way of transmission bearings;
- a clutch support arranged to support the first clutch and the second clutch radially by way of a support bearing, wherein the clutch support is situated in a position axially intermediate between the control system and an output hub of the clutch mechanism:
- at least one cooling duct arranged to make a cooling fluid circulate toward the first clutch and the second clutch, wherein each cooling duct comprises an axially extending part and at least one radially extending part;
- wherein the axially extending part of each cooling duct is situated radially between a transmission shaft and an interior face of the clutch support, and at least one radially extending part of each cooling duct is situated axially between the support bearing and the output hub, and
- wherein the clutch support is physically integral with the case of the control system.
