Brake drum for brakes jaws inland provided with means adapted to the braking noises mitigate

摘要

P the present invention relates to a brake drum in order to brake jaws inner wall with a limited by an inner cylindrical surface and an outer periphery of the drum brake, this wall being provided with means adapted to attenuate the noise of braking. / p & & p & according to the invention, at several points 14, 15, 16, 17 and 18 of the outer periphery 12, the thickness of the wall 13 extending in a mainly axial width of the outer periphery deviates slightly from the cylindrical symmetry of the inner periphery 11 of the brake drum 10, having a small increase in the normal thickness and in passing to a thickness that increases continuously in order to decrease again on the outer periphery with respect to the diameter of the brake drum. / p
