CLUTCHED POWER TRANSMITTING DEVICE WITH FILTER ELEMENT

摘要

A power transmitting device can include a clutch, filter and housing defining first and second sumps spaced apart by a first wall. First and second members can meshingly engage and rotate through the first sump. The clutch plates can rotate through the second sump. A third member can be drivingly coupled to the second member and clutch plates. An outer surface of the third member and the first wall can define an annular cavity that fluidly couples the sumps. The filter can be received in the annular cavity about the third member and can include a second wall, outer portion, inner portion, and a filter element. The second wall can define an aperture. The outer portion can seal with the first wall. The inner portion can seal with the outer surface. The filter element can span the aperture to permit fluid communication between the sumps and inhibit passage of solids.

主权项

1. A power transmitting device comprising:
a housing having a first wall, the housing defining a first sump and a second sump spaced apart from the first sump by the first wall; a fluid received in the first and second sumps; a first member received in the housing and configured for rotation relative to the housing; a second member received in the housing and configured for rotation relative to the housing, the second member being meshingly engaged with the first member and configured to rotate through the first sump; a clutch assembly including a plurality of first clutch plates and a plurality of second clutch plates interleaved with the plurality of first clutch plates, the first and second clutch plates being configured to rotate through the second sump; a third member having an outer surface, the third member being drivingly coupled to the second member and the first clutch plates, the outer surface and the first wall defining an annular cavity that fluidly couples the first and second sumps; and a filter disposed about the third member and received in the annular cavity, the filter including:
a second wall extending radially between the first wall and the outer surface of the third member, the second wall defining at least one aperture extending axially through the second wall;an outer portion coupled to the second wall and in sealing contact with the first wall;an inner portion coupled to the second wall and in sealing contact with the outer surface of the third member; andat least one filter element spanning the at least one aperture, the filter element being configured to permit fluid communication of the fluid between the first and second sumps through the at least one aperture and to inhibit passage of solid particulates.
