description | SE DESCRIBE UN DISPOSITIVO DE TRANSMISION CON APLICACIONES EN PARTICULAR EN EXCAVADORAS MOVILES, CARGADORES CON RUEDAS Y PLANTAS SIMILARES, QUE COMPRENDE UNA CAJA DE CAMBIO PLANETARIA CON PALANCA DE ENERGIA (4) TRANSMITIDA POR UN MOTOR HIDRAULICO (3). LA CAJA DE CAMBIO (4) TIENE PREFERIBLEMENTE DOS ENGRANAJES QUE PUEDEN SER ALTERNATIVAMENTE ENGANCHADOS Y DESENGANCHADOS HIDRAULICAMENTE POR MEDIO DE EMBRAGUES DE FRICCION (12, 13). LOS DOS EMBRAGUES (12, 13) SON CON CARGA DE MUELLE Y CONTROLADOS POR UNA PRESION DE ACEITE GENERADA POR UNA BOMBA DE ACEITE (21) Y SUMINISTRADOS A AMBOS EMBRAGUES (12, 13) POR UNA VALVULA DE PALANCA DE ENGRANAJE (23). UNO DE LOS EMBRAGUES (13) ESTA DISEÑADO COMO UN FRENO Y TIENE UN SUMINISTRO DE ACEITE DE GOTEO DE LIBERACION DE ACEITE ESTATICO. CUANDO LA PRESION GENERADA POR LA BOMBA DE ACEITE (21) CAE POR DEBAJO DE UN VALOR DADO, LA VALVULA DE PALANCA DE ENGRANAJE (23) ES CONECTADA A SU SEGUNDA POSICION DE ENGRANAJE EN LA CUAL SOLAMENTE EL FRENO ES ACCIONADO POR LAPRESION DE ACEITE. EN UNA EMERGENCIA EN LA CUAL SOLAMENTE ESTA DISPONIBLE UNA CANTIDAD LIMITADA DE ACEITE HIDRAULICO, ESTE DISPOSITIVO HACE POSIBLE QUE LA MAQUINA SIGA FUNCIONANDO DURANTE UN CIERTO PERIODO DE TIEMPO PORQUE SOLO ES ACCIONADO UN SOLO EMBRAGUE CASI LIBRE DE GOTEO DE ACEITE, POR EL ACEITE HIDRAULICO.

Date Oct. 18, 1990.A drive device specially used in mobile excavators, wheeled loaders and similar work machines contains a power-shiftable transmission (4) designed as planetary transmission and driven by a hydraulic motor (3). The transmission (4) preferably has two speed levels which are alternatively engageable and disengageable via hydraulically shiftable friction clutches (12, 13). Both friction clutches (12, 13) are designed as spring-accumulator clutches and are controllable by oil pressure generated by an oil pump (21) and both friction clutches (12, 13) are controlled via a gear-shift valve (23). One of the two friction clutches (13) is designed as brake and has a static, leakage-oil-free oil supply. When the oil pressure generated by the oil pump (21) falls below a specific value, the gear-shift valve (23) is engaged into its 2nd-gear position in which only the brake is actuatable with oil pressure. In an emergency where only limited amount of pressurized oil is available, this device makes possible a further opera |
