Abstract
A double wrap brake band is provided for use with a rotating element such as a rotating drum in an automatic transmission or the like. The double wrap brake band is provided with a friction surface on an inner circumferential surface of a band portion wrapped substantially double. The friction surface is provided with an inclined part such that the friction surface becomes gradually closer to an associated outer circumferential surface of the rotating element in a rotating direction of the rotating element.
Claims4
A double wrap brake band for use with a rotating element, said double wrap brake band being provided with a friction surface on an inner circumferential surface of a band portion wrapped substantially double, wherein said friction surface is provided with an inclined part such that said friction surface becomes gradually closer to an associated outer circumferential surface of said rotating element in a rotating direction of said rotating element.
A double wrap brake band provided with a double wrap band portion, a friction lining bonded on an inner circumferential surface of said band portion, and brackets secured on opposite free end portions of said band portion, respectively, said double wrap band portion being composed of a middle band as long as substantially a single wrap and outside bands as long as substantially a single wrap secured together at proximal end portions thereof, and said double wrap brake band being frictionally engageable with a rotating element located on an inner side of said double wrap brake band, wherein said friction lining is provided with an inclined part a thickness of which becomes gradually greater in a rotating direction of said rotating element.
