Abstract
A wet clutch includes a first friction disk including a first friction material having a first arrangement of cooling channels with a first fluid distribution, a second friction disk including a second friction material having a second arrangement of cooling channels with a second fluid distribution, the second arrangement of cooling channels being different from the first arrangement of cooling channels, and a separator disk positioned between the first and second friction disks.
Claims11
A wet clutch, comprising:
- a plurality of first friction disks including a first friction material on both sides of each first friction disk, the first friction material having a first arrangement of cooling channels with a first fluid distribution, the first arrangement of cooling channels including a first set of channels having a varying depth and a varying width and a second set of channels having a varying depth and a varying width, the second set of channels being different from the first set of channels;
- a plurality of second friction disks including a second friction material on both sides of each second friction disk, the second friction material having a second arrangement of cooling channels with a second fluid distribution, the second arrangement of cooling channels including a first set of channels and a second set of channels having different depths and different widths than the first and second sets of channels of the first arrangement, the second arrangement of cooling channels including a larger quantity of channels than the first arrangement of cooling channels, the second arrangement of cooling channels including deeper and wider channels than the first arrangement of cooling channels, the first arrangement of cooling channels including a first flow rate less than a preselected overall flow rate, the second arrangement of cooling channels including a second flow rate greater than the preselected overall flow rate, resulting in the combined first and second flow rates attaining the preselected overall flow rate, the plurality of first and second friction disks arranged in an other than alternating arrangement;
- and
- a plurality of separator disks positioned between each of the plurality of first and second friction disks.
