  • Rear disk brakes may be in common usage today. However, the vast majority of new cars and trucks still utilize rear drum brakes, since car manufacturers benefit from the lower cost of drum brakes to maintain the purchase price for a new vehicle at an attractive level for consumers.
  • drum brakes have significantly improved over the last twenty years there remain flaws in the design of drum brakes, which have not yet been fully addressed or resolved.
  • extreme braking conditions such as, for example, repeated high speed slow-downs, which, for example, may occur on a highway, or descent of a steep hill with a heavy load
  • the drum brakes are known to often fade and loose effectiveness, the consequence being the inability to arrest or slow down the vehicle as desired.
  • the accepted explanation for such failure to adequately perform under certain braking conditions was heat build up under the drum covering the brake system. It is known in the art that the performance of the brake is directly related to its capability of absorbing heat in the operation of the vehicle. If the brake becomes saturated with heat, the brake will no longer work efficiently.
  • drum brakes Another problem with drum brakes is potential brake lock up which can occur under cold, and/or damp or humid conditions, especially when the brakes have remained inactive for a long period of time in, for example, heavy rain or very humid or cold weather.
  • This type of lock up happens at low speed after initially moving the vehicle and during the first few stops.
  • the low speed lock up of the brakes is believed to be mainly caused by the mixture of dust accumulated inside the drum and deposited on the surface of the brake and the moisture in the air.

Abstract

La présente invention a trait à un dispositif de refroidissement anti-poussière ou à un ventilateur qui est utilisé avec un tambour de frein et qui est doté d'une plaque circulaire et d'une paroi cylindrique qui s'étend depuis une surface de la plaque de manière à former un élément de type tambour permettant de recouvrir étroitement un ensemble moyeu de support du tambour de frein. La plaque est pourvue d'une ouverture centrale permettant à la partie de tige de l'essieu d'un véhicule de passer par l'ouverture centrale et d'une pluralité d'ouvertures espacées autour de l'ouverture centrale, chacune des ouvertures est dimensionnée de manière à permettre à un goujon correspondant qui est attaché sur l'ensemble moyeu de support de passer par chacune des ouvertures dans la plaque puis par une ouverture correspondante dans le couvercle de tambour de frein de manière à permettre à la roue d'un véhicule d'être attachée de façon rotative au tambour de frein et à l'essieu du véhicule. La paroi cylindrique est pourvue d'une pluralité d'éléments espacés les uns des autres, ce qui permet à la fois de créer un écoulement d'air à l'intérieur de l'ensemble de frein lorsque le véhicule est en mouvement, d'empêcher la pénétration de la poussière et autre matériau particulaire de petite taille dans le tambour de frein et également de faciliter le refroidissement du tambour de frein.
