RING BRAKE COOLED BY AIR FLOW

摘要

The present invention relates to ring brake arrangements (5) and in particular to an effective arrangement for cooling of the brake. Heat is effectively transferred from the ring braking member (30) to a fanned hub arrangement (10) which transfers the heat energy to an axial air flow (70) which is pumped through the center of the brake. In addition heat is transferred to the brake caliper support bracket (41) from the brake caliper (40). The brake caliper support bracket (41) is located across the air flow (70) which serves to cool the same. This structure is particularly well suited for high brake demand requirements where heat build up causes problems or reduces braking efficiency. The brake can also be used to assist braking of trucks where the brake is located on the drive shaft. The brake is effective for most vehicle applications.
