Abstract

The drum for a brake or more particularly for a clutch in an automatic gearbox has a crenellated skirt inside which slide friction discs under the action of a piston to bear a similar discs fixed on another shaft. The crenellations on inside (5) or outside (6) are so formed as to have concave surfaces (7). This allows the radial length of the bearing surfaces to be maintained within a smaller overall radial dimension, or conversely allows a greater length within a given overall dimension because the rounded shoulders of the usual form are eliminated. The crenellations may be press or roller formd and a particular advantage of the concave tooth crest is that it forms passages for greasing or cooling oil.
