Brake disc with friction and thermal transition faces - is of reduced thickness towards hub and has intermediate ring(s) between friction rings

摘要

The brake disc (1) without inner ventilation has friction and thermal transition faces. The drive thickness diminishes in the hub direction, and between the friction rings is fitted at least one intermediate ring (4), forming groove (5) at both sides. The intermediate ring larger dia. lies below the brake disc dia. In the intermediate space is located a counter member, as an interference body (6), matching the contours of the friction ring inner sides, the intermediate ring, and the grooves. USE/ADVANTAGE - For rail vehicles etc., with heat transfer from axle vicinity to regions of high peripheral velocity.
