ABSTRACT:
The fluid friction clutch, suitable especially for the cooling fan of an internal combustion engine, has an aluminum housing mounted rotatably by means of a rolling bearing on a drive shaft. The outer race ring of the bearing is seated directly in a tubular bearing extension piece of the aluminum housing. A ring part, held on the bearing extension piece, of a material with lower coefficient of thermal expansion than aluminum, is secured on the bearing extension piece and prevents its widening with rising working temperature.
