Device to reduce dust emissions during vehicle braking, equipped with a brake drum brake and a system comprising such a device

摘要

A device to reduce dust emissions from the braking of a vehicle equipped with a drum brake, in particular a car vehicle, comprising a brake jaw,having a layer of friction material mounted on the base of the jaw, intended to attach the drum brake from the inside of the drum brake on a stationary shield and at least one suction cup,Designed to connect the pneumatic pipe to the source of the pressure, the suction hole is located outside the friction material layer (3a) of the friction lining of the brake jaw. In addition, the invention includes a vehicle braking system equipped with a drum brake, in particular a motor vehicle, incorporating such a device which contains additional pneumatic lines to connect the suction, in particular via a high-speed coupling (3d),with a low pressure source, preferably with a suction collector.
