Abstract
An apparatus for transferring torque from a crankshaft to a dual input transmission includes: a flywheel connected at one end to the crankshaft and at the opposite end to a torque transmitting device or dual clutch. The flywheel has a first coupling member that is configured to engage a second coupling member attached to a center plate of the dual clutch. The first coupling member is fixedly secured to the second coupling member by a fastening means. A dual clutch actuation device generates the axial compression force required to compress a first and second set of frictional elements of a dual clutch.
Claims19
A device for transmitting torque between a flywheel rotatably connected to an engine and a dual clutch transmission, the device comprising:
- a first coupling member fixed to a perimeter of a dual clutch of the dual clutch transmission, wherein the first coupling member defines a first bore having a radial centerline and having an open end;
- a second coupling member attached to a perimeter of the flywheel, wherein the second coupling member includes a second bore having a radial centerline and configured to extend through the second coupling member from a first side of the second coupling member to a second side of the second coupling member;
- and
- an engagement member disposed in the second bore and in the first bore thereby aligning the centerlines of the first and second bores and rotationally coupling the first coupling member with the second coupling member to allow the transfer of torque between the flywheel and the dual clutch transmission.
A device for transmitting torque between a flywheel rotatably connected to an engine and a dual clutch transmission, the device comprising:
- a clutch flywheel fixed to an outer perimeter of a dual clutch of the dual clutch transmission, wherein the clutch flywheel defines a first bore having a radial centerline and having an open end;
- a support disc attached to the flywheel, the support disc having an outer perimeter, and wherein the support disc includes a radially extending portion protruding from the outer perimeter, wherein the support disc includes an axially extending portion extending radially from the radially extending portion, wherein the support disc includes a second bore having a radial centerline and configured to extend through the axially extending portion from a first side to a second side of the axially extending portion;
- and
- an engagement member disposed in the second bore and in the first bore thereby aligning the centerlines of the first and second bores and rotationally coupling the first coupling member with the support disc to allow the transfer of torque between the flywheel and the dual clutch transmission.
A device for transmitting torque from an engine to a transmission, the device comprising:
- a flywheel assembly connected to the engine;
- a dual clutch connected to the transmission and having a center clutch plate disposed between two friction discs;
- a clutch flywheel fixed to an outer perimeter of center clutch, wherein the clutch flywheel defines a first bore having a radial centerline and having an open end;
- a support disc attached to the flywheel assembly, the support disc having an outer perimeter, and wherein the support disc includes a radially extending portion protruding from the outer perimeter, wherein the support disc includes an axially extending portion extending radially from the radially extending portion, wherein the support disc includes a second bore having a radial centerline and configured to extend through the axially extending portion from a first side to a second side of the axially extending portion;
- and
- an engagement member disposed in the second bore and in the first bore thereby aligning the centerlines of the first and second bores and rotationally coupling the clutch flywheel with the support disc to allow the transfer of torque between the flywheel assembly and the dual clutch.
