Abstract: There is described a brake shoe for a ring type brake which means it has a cylindrical brake ring secured to a member to be braked. The brake shoe comprises a part-cylindrical, preferably sheet metal support plate having on one face a brake lining and on the opposite face an elongate rib extending generally between opposed edges of the support plate and having a substantially flat bearing surface. Preferably the rib is stamped in the sheet metal support plate and receives a complementary portion of the brake lining material therein. The rib may be disposed cordally of the support plate or parallel to the generatrices thereof. Two such ribs may be provided on a support plate parallel to each other though spaced at different distances from median plane thereof. The contact areas of the substantially flat bearing surface with the piston of the hydraulic unit associated therewith are preferably dissymmetrical about one or both of the median planes of the brake shoe.

Abstract: The invention relates to friction discs of the progressive engagement type, especially for clutches of heavy automobile vehicles, the disc comprising two annular friction linings extending respectively on both sides of and in contact with a cut-out corrugated support, each lining being fixed individually by continuous glueing zones on this support, along parts of the corrugations of the support which are in contact with the lining. The surface area of the glueing zones should be between 5 and 35%, and preferably about 10% of the surface area of the lining. In a modification, each lining is fixed on the support, not only by the glueing zones but also by at least one rivet per zone arranged at right angles to each glueing zone. The riveting operation is preferably carried out after glueing and before the adhesive is polymerized or set.

Abstract: The invention relates to a fluid-operated clutch and provides a clutch operating thrust bearing which is formed with a generally stirrup-shaped casing which may be located in position on a sleeve co-axial with the driving and driven shafts by simple engagement.

Abstract: Apparatus for cooling liquids, especially lubricating oil for internal combustion engines or heat engines, etc., including a heat exchanger formed by at least one tube for circulating said liquid to be cooled, immersed in a cooling liquid. The exchanger is connected to the outside circuit by connectors passing through the wall of the container of the cooling liquid. These connectors are formed in two parts, one of which projects externally, said parts being so shaped that when assembled they jointly form an annular cavity which surrounds the edge of the opening formed in the container wall; the volume of said cavity diminishes gradually when said two parts are joined together whereby to confine and tighten a flexible seal placed within said cavity.

Abstract: A sub-assembly for a diaphragm clutch comprises a clutch cover, a diaphragm, and connecting means rockably fastening the diaphragm to the cover with the interposition of a supporting washer. The connecting means comprise flat, relatively thin claws which extend from the front face of the cover through openings in the diaphragm and which are provided at the end of their axial portion with a wing portion which is bent over to retain the supporting washer; the entire supporting washer is disposed radially outside the diameter on which the axially extending portion of the claws lie.

Abstract: The invention relates generally to an assembly unit for a clutch, especially for automobile vehicles, and comprising an annular cover, a pressure-plate fixed for rotation with the cover and movable axially with respect to this latter, an elastic diaphragm with controllable action interposed between the cover and the pressure-plate and tending especially to move this plate away from the cover, a friction-disc adapted to be coupled for rotation with a first or driven shaft, and a reaction-plate intended to be coupled to a second or driving shaft, the assembly unit being adapted for fixing by the periphery of the cover on the reaction-plate so as to effect a controlled gripping of the friction-disc between the pressure-plate and reaction-plate, the cover periphery comprising radial fixing zones; the cover is provided at positions along its periphery with spacing members which project from the fixing zones, these members being fixed permanently on the cover periphery and extending substantially radially, each spa

Abstract: A disk brake, preferably for use in connection with industrial machinery, has a pair of braking levers which carry at one end brake shoes located on opposite sides of the disk.
