Title (EN) HYDRAULICALLY COOLED SPHERE DRIVE LINE RETARDER
(FR) RETARDATEUR DE LIGNE D'ENTRAÎNEMENT DE SPHÈRE À REFROIDISSEMENT HYDRAULIQUE
Abstract:
(EN) A sphere drive line retarder is presented that is mounted to a drive shaft from an engine. The sphere drive line retarder comprises a sphere rotor mounted to the drive shaft and housed within a retarder housing. The sphere drive line retarded has a piston assembly comprising at least one piston, a brake shoe mounted to each piston, and hemispherical friction material mounted to the brake shoe. The hemispherical friction material is located between the sphere rotor and the brake shoe. Each piston is housed within a piston housing that is hydraulically isolated from the retarder housing. The retarder housing contains hydraulic fluid to cool the sphere rotor.
(FR) La présente invention a trait à un retardateur de ligne d'entraînement de sphère qui est monté sur un arbre d'entraînement à partir d'un moteur. Le retardateur de ligne d'entraînement de sphère comprend un rotor sphérique monté sur l'arbre d'entraînement et logé à l'intérieur d'un boîtier de retardateur. La ligne d'entraînement de sphère retardée comporte un ensemble piston comprenant au moins un piston, un sabot de frein monté sur chaque piston, et un matériau de friction hémisphérique monté sur le segment de frein. Le matériau de friction hémisphérique est situé entre le rotor sphérique et le segment de frein. Chaque piston est logé à l'intérieur d'un logement de piston qui est isolé hydrauliquement du boîtier de retardateur. Le boîtier de retardateur contient un fluide hydraulique pour refroidir le rotor sphérique.
