A brake band suitable for use in a vehicle transmission is described. The brake band is composed of a band portion, such as a metal strap, and a brake lining bonded at an outer peripheral surface thereof on an inner peripheral surface of the band portion and has an apply side end and an anchor side end located opposite to each other relative to a circumferential length of the brake band. The brake lining is provided with oil-dependent, friction surface cooling grooves having bottom walls, respectively. Each cooling groove is provided with a discharging aperture extending through the bottom wall of the corresponding cooling groove to the outer peripheral surface of the brake lining. Adjacent to the anchor side end of the brake band, the brake lining is also provided with an oil film formation promoter, for example, in the form of one or more recesses not extending to the outer peripheral surface of the brake lining. As an alternative, the oil film formation promoter can also be provided by leaving the brake lining as is, that is, without forming any recess, groove, aperture or the like in the vicinity of the anchor side end.
A brake band suitable for use in a vehicle transmission, said brake band comprising a band portion and a brake lining bonded at an outer peripheral surface thereof on an inner peripheral surface of said band portion and having an apply side end and an anchor side end located opposite to each other relative to a circumferential length of said brake band, the improvement wherein said brake lining is provided with oil dependent, friction surface cooling means and oil discharging means and, adjacent to said anchor side end of said brake band, with means for promoting the formation of an oil film, and further wherein said friction surface cooling means and said means for promoting are arranged asymmetrically relative to a central line through said brake lining transverse to a longitudinal central axis of said brake lining;
A brake band suitable for use in a vehicle transmission, said brake band comprising a band portion and a brake lining bonded at an outer peripheral surface thereof on an inner peripheral surface of said band portion and having an apply side end and an anchor side end located opposite to each other relative to a circumferential length of said brake band, the improvement wherein said brake lining is provided with oil dependent, friction surface cooling means and oil discharging means and, adjacent to said anchor side end of said brake band, with means for promoting the formation of an oil film, and further wherein said friction surface cooling means and said means for promoting are arranged asymmetrically relative to a central line through said brake lining transverse to a longitudinal central axis of said brake lining;
A brake lining for a brake band suitable for use in a vehicle transmission and having a band portion, having an outer peripheral surface and having an apply side end and an anchor side end located opposite to each other relative to a circumferential length of said brake band, the improvement wherein said brake lining is provided with oil dependent, friction surface-cooling means and oil discharging means and, adjacent to said anchor side end of said brake lining, with means for promoting the formation of an oil film, and further wherein said friction surface cooling means and said means for promoting are arranged asymmetrically relative to a central line through said brake lining transverse to a longitudinal central axis of said brake lining;
A brake lining for a brake band suitable for use in a vehicle transmission and having a band portion, having an outer peripheral surface and having an apply side end and an anchor side end located opposite to each other relative to a circumferential length of said brake band, the improvement wherein said brake lining is provided with oil dependent, friction surface cooling means and oil discharging means and, adjacent to said anchor side end of said brake lining, with means for promoting the formation of an oil film, and further wherein said friction surface cooling means and said means for promoting are arranged asymmetrically relative to a central line through said brake lining transverse to a longitudinal central axis of said brake lining;
