Abstract
A clutch assembly with a rotatable clutch hub which is connected rotationally fixedly to several inner plates which may be brought into friction connection with outer plates of an associated clutch basket and form a plate pack. The clutch hub has at least one bore which allows a throughflow of a fluid from the interior of the clutch to the plates, and an oil conduction device attached to the clutch hub at the at least one bore.
Claims20
A clutch assembly, comprising:
- a clutch basket;
- a plate pack having a plurality of inner plates and a plurality of outer plates which are configured for a friction connection to the inner plates;
- a rotatable clutch hub operatively connected to the clutch basket and the inner plates, the clutch hub having at least one bore which facilitates a throughflow of a fluid from the interior of the clutch to the plate pack;
- and
- a conduction device operatively connected to the clutch hub at the at least one bore.
2 more elements
A clutch assembly, comprising:
- a clutch basket;
- a clutch hub operatively connected to the clutch basket, the clutch hub having a shaft portion extending along a longitudinal axis, a first wall portion extending radially from the shaft portion, a shoulder portion extending from the wall portion in an orientation parallel to the shaft portion, a second wall portion extending radially from the shoulder portion, and a plurality of bores provided in the shoulder portion;
- a plate pack arranged on the second radial wall portion and which surrounds the shoulder portion, the plate pack having a plurality of alternatively arranged first plates and second plates configured for operational engagement with each other by friction fit through an application of an axial force;
- and
- a conduction device operatively connected to the clutch hub and configured to cool and lubrication the friction faces of the first plates and the second plates.
2 more elements
A method for distributing a fluid in a clutch, comprising:
- establishing an operative, rotatable connections between a clutch basket, a clutch hub, and a plate pack of the clutch;
- using the centrifugal force of the rotating clutch basket and the clutch hub such that fluid in the clutch flows in the direction of the plate pack via the clutch hub;
- and then
- guiding the fluid flow to separate regions of the plate pack.
