Abstract
Official abstract text for this publication.
A fluid clutch device having a fluid clutch in a body and a cover. A fan member is attached to the device. The body and fan member are both centered on the cover.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fluid clutch device ( 1 ) comprising: a clutch body ( 2 ); a fluid clutch positioned in the clutch body; a cover ( 3 ) which is fastened to the clutch body ( 2 ), and having a fan impeller ( 4 ) which is fastened to the cover ( 3 ); the cover ( 3 ) having a cylindrical surface ( 5 ) for centering both the clutch body ( 2 ) and the fan impeller ( 4 ); the cylindrical surface ( 5 ) being an outer lateral surface of the clutch body; the cylindrical surface ( 5 ) having a plurality of first partial regions ( 6 ) on its periphery, the first partial regions ( 6 ) having a groove ( 8 ) with an inner surface ( 7 ) on which the clutch body ( 2 ) is centered on the cover ( 3 ); the cylindrical surface ( 5 ) also having a plurality of second partial regions ( 9 ) on which the fan impeller ( 4 ) is centered on the cover ( 3 ), the cylindrical surface ( 5 ) being exposed in the second partial regions ( 9 ); and the first and second partial regions ( 6 , 9 ) of the cylindrical surface ( 5 ) arranged in an alternating manner. 2. The fluid clutch device as set forth in claim 1 wherein the cylindrical surface ( 5 ) on the cover ( 3 ) is produced by performing a single machine processing operation. 3. The fluid clutch device as claimed in claim 1 , wherein the cover ( 3 ) is formed as a cast part.
