Ring brake and caliper cooled by air flow

摘要

The present invention relates to ring brake arrangements and in particular to an effective arrangement for cooling of the brake. Heat is effectively rendered from the ring braking member by a fanned hub support arrangement which transfers the heat energy to an axial air flow which is pumped through the center of the brake. In addition heat is transferred to the brake caliper support bracket from the brake caliper. The brake caliper support bracket is located across the air flow 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 or can assist brake for trucks where the brake is located on the drive shaft.
