Abstract
For a flywheel which has two centrifugal masses and is located in the drive train of a motor vehicle, which two centrifugal masses can rotate in relation to one another and can be guided by a bearing, the bearing neck which holds the bearing on the first centrifugal mass can include a multiplicity of disc-shaped neck parts. These neck parts can be firmly fastened to one another, and to the first centrifugal mass, by rivets. The individual neck parts can be centered relative to one another and to the first centrifugal mass by centering members, independently of the rivets.
Claims19
A flywheel assembly for a motor vehicle for transmitting mechanical rotary power from an internal combustion engine to a transmission, said flywheel assembly comprising:
- a first flywheel portion, said first flywheel portion having an axis of rotation and defining an axial direction parallel to said axis of rotation;
- said first flywheel portion comprising means for fastening said first flywheel portion to a crankshaft of an internal combustion engine;
- a second flywheel portion disposed adjacent said first flywheel portion, said second flywheel portion being rotatable with respect to said first flywheel portion;
- bearing means for guiding said second flywheel portion with respect to said first flywheel portion;
- means for mounting said bearing means;
- means for fastening said mounting means to said first flywheel portion;
- said mounting means comprising:
- a first neck part;
- a second neck part disposed adjacent said first neck part, said second neck part comprising a seat surface for said bearing means;
- and
- said first neck part comprising a portion extending radially outwardly beyond said seat surface of said second neck part and forming a stop shoulder for said bearing means;
- means for centering said mounting means in a radial direction with respect to said first flywheel portion and for centering said first neck part and said second neck part with respect to one another;
- said second neck part having a first side facing said first flywheel portion and a second side facing away from said first side, said first neck part being disposed adjacent said first side of said second neck part;
- said mounting means further comprising a third neck part disposed axially between said first flywheel portion and said first neck part;
- and
- said centering means centering said first neck part, said second neck part, and said third neck part with respect to one another.
