Title: Improvements in or relating to electro-magnetically controlled friction clutch
IPC: F16D27/08
Filed: 1950-03-06
Abstract: 674,531. Electromagnetic friction clutches. SIPER SOC. ANON. March 6, 1950 [Nov. 3, 1949], No. 5640/50. Class 80 (ii). In an electromagnetically operated friction clutch, an armature disc and flywheel 1 is secured to a driving shaft 2, an electromagnet 5 being rotatable and axially movable on a. driven shaft 6 carrying a disc 11 with friction linings 13 The disc 11 is resilient i.e., elastically deformable, so that it is moved away from the armature 1 when the electromagnet 5 is switched off ; alternatively it is mounted on a spring-urged sleeve 10 sliding axially on the shaft 6. When no current flows through the electromagnet 5 it is held away from the armature disc by springs 15. A ring shaped winding 19 is mounted in a circular groove of the electromagnet 5 and is partially covered by a ring 20 of magnetic material having a cylindrical flange forming one of the poles, the other pole being formed by a cylindrical flange 21 of the electromagnet. The faces of the poles may be flat, as shown, or conical so that the groove between them has a trapezoidal cross-section. This groove may co-operate with a rib on the armature disc 1 of similar cross-section, so reducing variations in the size of the air gap due to wear of the linings 13. The linings 13 may be of asbestos, or of a fritted material which can be made magnetic by incorporating ferro-magnetic filings in the non-magnetic binder. In this latter case the poles of the electromagnet can be arranged to press directly on the linings. The ring 20 is interchangeable and can be made of wear-resisting magnetic material such as cast-iron or steel.

As shown the plates A, B are mounted on hub rings 16, 17 respectively which are keyed to the shaft 11 and are engaged by the rods 50. The hub rings 16, 17 serve to clamp the edges of an inner diaphragm D to the plates A, B to restrict the size of the inflatable chamber and thereby reduce the axial forces of inflation exerted on the plates A, B. The hub rings 16, 17 serve also to support slidably a pair of rings 66 to the peripheries of which are clamped inflatable ply-turnover bags G, the bags G co-operating with baffle plates 78 slidably carried on the hubs 67 of rings 66 to effect turnover of the carcase ply ends about the bead rings 81, Fig. 6. Setting of the bead rings 81 is effected by bead setters E, F which are respectively screwable along the sleeve 11 and along a hub member 42 surrounding the sleeve 11. The hub member 42 carries the sun wheel 58 at one end and a brake element 59 at the other end, the brake element co-operating with a fixed inflatable brake annulus 60 to lock or release the hub from rotation with the sleeve 11. In operation, after building the flat band carcase 80, effecting ply turnover, and applying the tyre sidewall rubber 84, a lock 62 on the end of one of the rods 50 is released and the shaft 10 rotated with the hub 42 locked against rotation by the brake 60. The rods 50 are thereby rotated to effect mutual approach of the plates A, B, and simultaneously the chamber between the diaphragms C and D is inflated to shape the carcase to tyre form. At the desired spacing of the plates, the brake 60 is released and the rod lock 62 applied, and the tyre is completed by application of the undertread bands 85 and the tread rubber 86.
