International Classification:

B23P 25/00
B23P 17/00
F16D 65/12
B22D 19/00

US Classification:

29458, 29460, 295272, 295273, 295275, 188218 XL, 164 98

Abstract:

The invention provides a method for manufacturing a friction damped disc brake rotor, including the steps of: (A) providing a ceramic coating on an insert, wherein the insert has a body with tabs extending therefrom to hold the insert in a desired position within a mold; (B) washing the ceramic coating off of the tabs; (C) positioning the insert into the mold; and (D) casting a rotor cheek of the disc brake rotor in the mold around the insert such that a portion of each tab is bonded with the rotor cheek, and such that the coating is substantially non-bonded with the rotor cheek so that the coating provides a proper interfacial boundary between the body and the cheek for damping, and the at least partial bonding of each tab with the rotor cheek prevents corrosion-causing exterior elements from reaching the interfacial boundary when the friction damped disc brake rotor is in use.

Jeremy Short - Berkley MI, US

International Classification:

F16F 9/04

US Classification:

267064270

Abstract:

The present invention concerns an air spring and jounce shock assembly for use in an automotive vehicle suspension system. The assembly may include a base adapted to be mounted on one of an axle assembly and a suspension component, a top cap adapted to be attached to a vehicle frame, and a diaphragm disposed between and attached to the base and the top cap, with the diaphragm including an inner surface defining a first portion of a compressed air cavity. A jounce shock reaction surface defines a second portion of the compressed air cavity and is included in a one of the top cap and the base. A jounce shock assembly is disposed in the air cavity in opposed relation to the jounce shock reaction surface and affixed to an other of the top cap and the base, with the jounce shock assembly including a body, affixed to the other of the top cap and the base and defining a compressed gas chamber, and a rod having a first end portion in the compressed gas chamber sealably engaged with and slidable relative to the body and a second end portion telescopically slidable from the body and located to selectively engage the jounce shock reaction surface.
