#CMT# #/CMT# Open incisions (20, 22) are made into the hub (14) of the brake disc (12), near the fastenings (18) holding them together. Each has a defined gap. This provides radial flexibility between hub and fastening or friction disc. Close to the fastenings, each slit runs tangentially and/or radially. The several slits are spaced apart circumferentially. Each tongue-like profile defined by a slit, runs around the hub. The arrangement subjects the tongue to tension, under normal braking torques. #CMT#USE : #/CMT# A brake disc for a road vehicle. #CMT#ADVANTAGE : #/CMT# The design improves damping characteristics and compensates differential thermal expansion between the disc and its hub. Unacceptable stressing is avoided. This is significant because the disc can be a fiber-reinforced metal ceramic composite with a metal (e.g. steel or aluminum) hub. The connection made between disc and hub, is robust and durable. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of the disc and hub assembly 12 : brake disc 14a : wheel flange 14 : hub 18 : fastenings 20, 22 : open slits. |
