Abstract
A wet type band apparatus characterized by the construction that, in the wet type band brake apparatus provided on the outer periphery of the brake drum with the lining fixed on the inner periphery of the brake band, a groove is cut on the contact surface of the lining in the peripheral direction, oil holes are perforated through the brake band and lining with their openings in the groove and at the same time, lubricating oil is supplied to the aforesaid oil holes and the discontinuous part located at the opening of the aforesaid brake band respectively.
Claims3
A wet type band brake apparatus comprising a brake drum, a brake lining mounted on the periphery of said brake drum, said brake lining having a groove along the entire circumference of the contact surface thereof and a hole passing through said lining into said groove to introduce oil therethrough, a brake band mounted on the periphery of said brake lining, said brake band having a hole therein aligned with the hole in said brake lining to introduce oil therethrough, an inlet port for oil positioned at a discontinuous portion of said brake lining and said brake band and, means for introducing oil into said hole in said brake band and said inlet port whereby oil flows through said hole in said brake lining, into said groove and then onto the contact surface of said brake lining thereby cooling friction heat caused by braking action.
