Abstract:
A clutch drum assembly comprising a clutch drum (21) and a drive means. The clutch drum (21) has an axis of rotation and includes an end wall (22). The drive means specifically a drive spline (1) or a fixed drive sprocket axially to one end of drive means, is a flange (5) with one or more radial evenly spaced minimally sized apertures (6) that have been counter sunk or counter bored to one side. Unitary axial motion of the two components is achieved via a mechanical connection between the two said components by tightly pressing metal from the outer surface of the end wall (22) clutch through each of the minimally sized apertures (6) in the drive means flange (5) against a die positioned proximate to each said aperture (6) forging the metal into the counter sunk or counter bored portion of the drive means flange (5).

Abstract:
A method for antirust treatment of a rotating brake member, wherein outer side and inner side rubbing surfaces, (2a) and (3a) respectively, of a disc brake rotor (1) made of cast iron are subjected to an electrolysis treatment in a phosphate film forming solution containing a phosphoric acid ion, a zinc ion and a nitric acid ion, to thereby form a zinc phosphate film (8) having a film thickness of 1 to 10 mu m, desirably 2 to 8 mu m, a mass of 4 to 35 g/m and a crystal grain size of 50 mu m or less on the rubbing surfaces. The treatment according to the method markedly improves the antirust corrosion resistance of rubbing surfaces, (2a) and (3a).

Abstract:
A brake drum includes a ring-shaped drum body (13), and a friction member (16) secured to the inner circumferential surface (18) of the drum body. Because the drum body is formed of a lightweight A1 alloy and the friction member is formed of an A1-base composite material, the brake drum can be reduced in weight as a whole. Further, because the friction member, having projecting portions (17a) formed on its outer periphery (17), is cast-enveloped by molten metal of the A1 alloy, the friction member and the drum body can be firmly fastened together. Thus, even when a great braking force is applied to the drum brake, the friction member can be prevented from being undesirably detached from the drum body.

Abstract:
An improved structure for a brake drum adapted for use in a drum brake assembly includes a generally closed outer end, a generally axially extending cylindrical main body, and an open inner end. The closed outer end of the brake drum includes a centrally located wheel spindle opening formed therein, and a plurality of lug bolt mounting holes spaced circumferentially around the wheel spindle opening. The cylindrical main body of the brake drum includes a plurality of generally axially extending raised ribs provided on an outer surface thereof. Preferably, the ribs define at least three distinct strengthened areas on the brake drum. 00000
Abstract:
This invention concerns a process and device for producing a brake drum or a brake disk comprising a carrier element made from the most economical light metal alloy which can be easily cast and machined and a friction lining made from a short-fiber or particle-reinforced light metal alloy; said process comprising the following steps: produce the carrier element or the friction lining in a mold, cool the carrier element or friction lining to a temperature at which the material maintains its shape, cast the particle-reinforced light metal alloy on the carrier element, or remelt the carrier element with the particle-reinforced light metal alloy, or cast the light metal alloy for the carrier element on the friction lining, or remelt the friction lining, cool and remove from the mold.
Abstract:
In a drum brake for heavy vehicles liable to make brake noise during brake activation the noise may be eliminated by applying to the outside of the brake drum (3) a layer (14, 15) of a non-metallic, at least partly elastically deformable material and a steel ring (16) causing a substantial compression force upon the drum (3) via the non-metallic layer (14, 15), the said steel ring (16) being mounted by being opened by a radial cut, heavily pre-stressed and finaly closed by being welded in place. According to the invention it has been possible to weld such heavy steel ring (16) in place by welding a steel sheet (18) to the inner side of the ring (16) prior to the mounting of the steel ring (16) around the brake drum (3), said steel sheet (18) being directed concentrically towards the inner cylindrical surface of the ring (16) on the other side of the ring opening.

In accordance with one aspect of the present invention, a material (115) for an element of a power transmission-absorption assembly and the method and making such material (115) is disclosed. The material (115) comprises a plurality of first yarns (45, 55, 60) woven with a plurality of second yarns (47a, 47b, 50) to form a pre-selected channel configuration (46, 48, 65, 70) to permit flow of a cooling medium thereacross or therethrough.
Abstract:
A brake drum is formed by a cylindrical member (111, 211, 311) having an inner circumferential surface against which a brake lining (4) is pressed, an annular pressure receiving portion (112, 212, 312) formed on an outer circumference of the cylindrical member, a damping member (30, 40, 70, 80) provided in contact with the pressure receiving portion, and a tightening bolt for pressing the damping member against the pressure receiving portion. When the drum is vibrated due to the friction between the lining and the inner circumferential surface of the drum during the application of the brake, a relative slip occurs between the pressure receiving portion and a contact surface (opposed surface) of the damping member in accordance with the deformation of the drum which causes this vibration to occur. Since a frictional resistance between the contact surfaces works on this relative slip, the vibration of the drum is damped quickly, and a searching of the brake is minimized.
