Brake disc rotor with at least two spaced slide discs - has specially shaped ribs formed by different length partitions and several ventilation holes to improve cooling efficiency.

摘要

The disc-like friction plates (11) are arranged axially separated on the inner and outer sides of the rotor (1) and each have a slide face on one of their sides. Several long partitions (22) extend radially from an inner smaller diameter area to an outer area of the plates and are inclined to the radial direction of the rotor. Several short partitions (21) provided between each adjoining long partitions extend from an inner larger diameter area to the outer area of the slide plates and are inclined to the radial direction. Several passages (41,42) are formed radially between the long and short partitions and communicate with several inlets and outlets (31,32) which open radially inwards and outwards. USE/ADVANTAGE - Disc brake with reduced heat transfer coefficient and improved cooling action of the rotor.
