The invention provides an improved attachment arrangement and method for attaching a temperature responsive bi-metallic strip to the housing of a fluid friction clutch of the type having a rotatable disk disposed to rotate in a work space of a relatively rotatable housing. The work space is separated from a clutch fluid reservoir by an intermediate disk fixed to the housing and the flow of clutch fluid into the work space is controlled by a valve lever which is movably mounted for controlling the opening of a bore through the intermediate disk. The valve lever is in turn controlled by a temperature responsive bi-metallic strip mounted at the cover of the housing and a movable member extending through the housing cover and engageable with the bi-metallic strip and the valve lever. The bi-metallic strip is held in place by being clamped under ribs provided at the front side of the housing cover and is held by means of tongues at the bi-metallic strip which are abuttingly engageable with the cooling ribs. An elastic securing medium is arranged in the region of the clamping position of the bi-metallic strip for fixedly holding the bi-metallic strip at the housing cover. With this arrangement, the bi-metallic strip is fixedly attached during its assembly in the factory and cannot be taken off of the cover without disturbing the elastic securing medium. In this way, a constant clutch characteristic is guaranteed. |
