摘要:
A method of forming a cast component (10) to have particular NVH characteristics. The method includes selecting an insert (14, 15) for integral casting with the cast component (10), the insert (14, 15) being one which is of a material capable of altering the NVH characteristics of the cast component (10), which can be infiltrated by molten metal during casting and which has characteristics that can be altered by alteration of the composition of the insert material. The method includes determining the material composition required to achieve the desired NVH characteristics and further includes determining the appropriate position (14, 15) for the insert to be inserted into the cast component (10) and casting the insert (14, 15) into the component (10) in that position.
摘要:
The invention relates to a disk brake (1) which comprises a brake disk ring (2) which is made of brittle material. Said brake comprises, in said ring, receiving holes (18) for lowering rivets (3) and a particular shaping about said holes (19). Said brake also comprises an inner rim (4) which is made of high-grade steel or other similar material, which is riveted to the brake disk ring (2), and which is elastic and comprises star-shaped flat spokes (20), and an intermediate ring (6) which is made of a light metal or similar material which is riveted or screwed to said rim. Said ring can be machined, for the purpose of lag-freedom, parallel to the disk ring surface (13) and adapted to the connection by screwing or riveting (7).
摘要:
The present invention relates to a disc for a disc brake comprising a support bell and braking band being coaxial with each other. The support bell has a plurality of radial housings and the braking band has a plurality of connecting elements suitable to connect it to the bell. The connecting elements are integral and made as one piece with said braking band and overhang from the braking band in order to engage the corresponding radial housings. The connecting elements are at least partially surrounded by walls being integral and made as one piece with the support bell such as to be fastened in the axial direction and in the tangential direction and such as to be capable of sliding in the radial direction.
摘要:
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.
摘要:
The invention provides a lightweight brake drum (10) comprising a lightweight, tubular inner member (14) having a reinforcement wrapping retention pattern (e.g., groove) cast in the exterior surface thereof, a length of reinforcement material (e.g., wrapped wire, cable, mesh, fibers, etc.) (16) in communication with a reinforcement retention pattern (e.g., a groove around the inner member) (14), the drum including an outer shell (18). The inner member (14) and the outer shell (18) are made of lightweight materials. Single, or multiple layers of reinforcement material (e.g. wrapping) are applied (e.g., wrapped) around the inner member (14) to support and inhibit expansion of the inner member (14). Because the reinforcement material (16) provides support against expansion, the inner member (14) and the outer shell (18) can be made of lightweight materials. In preferred embodiments, a bonding layer (66) is applied to the exterior surface of the inner member prior to application of the reinforcement material thereon. In preferred embodiments the reinforcement material comprises a low-impedance material such as copper along with another material that has good tensile strength characteristics (e.g., steel, composite fibers, Basalt-fibers, etc.). Preferably, the inner member comprises at least one material selected from the group consisting of a aluminum-based metal matrix composite (MMC) with a particulate reinforcement, ceramic matrix composite (CMC), and carbon graphite foam.
