摘要： An automatic air gap readjusting assembly in a clutch or brake unit is operated by electromagnetic and spring forces. A drive shaft 3 frictionally mounts, by a plurality of O-rings, an adjustment member. The adjustment member is readjusted by a contact or armature plate such that the air gap between the armature plate and the electromagnetic mechanism attracting the armature plate will remain constant, i.e. the stroke of the armature plate will remain constant. Torque is transmitted from the drive shaft to the armature plate via a radial flange having a plurality of axially movable torque transmitting bolt assemblies, which are clamped to an annular spring member secured to the armature plate. This arrangement allows for continuous readjustment for wear of the air gap between the armature plate and the electromagnetic mechanism; furthermore, the readjustment always takes place under uniform force conditions despite increasing wear.

摘要： A rear wall for a standard housing, which housing is adapted for receiving electronic assemblies. The rear wall is provided by an enclosure in the form of a hollow body with mounting flanges for mounting the hollow body to one end of the housing so as to form a housing rear wall. A power pack for supplying power to the electrical assemblies is mounted in the hollow body so that heat may be transferred and carried off towards the outside of the housing. Ventillators and vent openings are provided in the hollow body to enable forced ventilation cooling of the power pack as well as to enable heat transfer from the housing interior. The mounting flanges are positionally located on the hollow body so that the formed housing rear wall is provided within the housing interior and the hollow body extends from the housing rear wall outwardly so as to partially project from the housing.
