Abstract
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.
Claims17
A vehicle brake comprising
- a ring braking member having braking surfaces to both the interior and exterior of said member,
- a support arrangement securing said ring braking member for rotating about a center axis of said support arrangement,
- said support arrangement including a hub of a diameter less than the diameter of said ring braking member with said hub being connected to said ring braking member by intermediate radial members spaced about said hub and having air passages therebetween open to the exterior and open to a central cavity open at the interior of said brake, said radial members promoting the passage of an axial air flow through the center of said brake between the exterior and interior of the brake when said support is rotated about the center axis,
- a brake caliper arrangement including a brake caliper supporting and controlling opposed braking pads located to opposite sides of said ring braking member, said brake pads when actuated by movement of said brake caliper commonly braking said ring brake member,
- a fixed support bracket for said brake caliper located within said central cavity and across said axial air flow and of a truss structure having a large surface area generally aligned with and in contact with said axial air flow as it passes through and around said support bracket and effectively transferring heat energy from said support bracket to said axial air flow,
- said support bracket contacting said brake caliper to form an effective thermal transfer relationship therewith such that said support bracket acts as a heat sink for said brake caliper and indirectly acts as a heat sink for said brake pads.
