PNEUMATIC CONSTRICTING DRUM BRAKE ASSEMBLY

摘要

The present disclosure describes a pneumatically operated constricting drum brake with rotary seals provided for the hub of the rotating drum on axially opposite sides of the hub for sealing the interior of the hub of the rotating drum from exterior contaminants such as moisture, brake dust, and foreign matter. The brake assembly of the present disclosure has the central region provided with rotary seals on opposite sides of the housing. Both seals may be accessed for replacement from the one side of the housing, opposite the input shaft, by removal of the side plate and the brake drum, without removal of the hub from the input shaft.
