Title (EN) PLANETARY WHEEL DRIVE BRAKE
(FR) FREIN D'ENTRAÎNEMENT DE ROUE PLANÉTAIRE
Abstract:
(EN) A planetary wheel drive uses a brake having a stamped spring plate which includes a plurality of spring stabilizer connections. Each one of the plurality of springs is mechanically bonded to a respective one of the plurality of spring stabilizer connections. A brake piston includes a bore therethrough and resides in sliding engagement with the stationary spindle. The brake piston is generally cylindrically shaped with an inner portion and an outer portion. The plurality of coil springs reside between said spring stabilizers and said inner shoulder of said brake piston. Pressurized hydraulic fluid releases the brake.
(FR) Entraînement de roue planétaire utilisant un frein ayant une plaque de ressort estampée qui comprend une pluralité de raccords de stabilisation de ressort. Chaque ressort de la pluralité de ressorts est lié mécaniquement à un raccord respectif de la pluralité de raccords de stabilisation de ressort. Un piston de frein comprend un trou à travers celui-ci et se trouve en prise coulissante avec la broche fixe. Le piston de frein est globalement de forme cylindrique avec une partie intérieure et une partie extérieure. La pluralité de ressorts hélicoïdaux se trouvent entre lesdits stabilisateurs de ressort et ledit épaulement intérieur dudit piston de frein. Un fluide hydraulique sous pression libère le frein.
