The transmission is for a motor vehicle with transverse engine with coaxial flange-mounted automatic gearbox and torque converter between. Gear changing is by means of selector clutches, brakes and freewheels. - The annulus (32) forming the driven member of an epicyclic reduction gear train (3) is rigidly coupled to an output gear (31) and directly alongside the change-speed gear train. The freewheel (G) necessary for better control of gear changing is behind this gear in the axial direction. The coupling (320) from a further transmission member e.g. the planet carrier (35) to the freewheel is taken through the spur output gear (31).

ENTRE EL MOTOR DE ACCIONAMIENTO (NO MOSTRADO) Y EL ENGRANAJE DE CAMBIO DE MARCHAS (1) SE HA DISPUESTO ADEMAS UNA UNIDAD HIDRODINAMICA, PREFERENTEMENTE UN VARIADOR HIDRODINAMICO (2). MEDIANTE EMBRAGUES DE CAMBIO (A, B, E) Y FRENOS DE CAMBIO (C, C1, D) Y PI ONES LIBRE (F, G), SE CAMBIA LAS MARCHAS A CUYO EFECTO EL MOMENTO SALIENTE SE TRANSMITE POR UNA RUEDA DENTADA RECTA DE SALIDA (31), LAS RUEDAS DENTADAS RECTAS (51, 52, 41) Y UN ARBOL LATERAL (5) A UN ENGRANAJE DE LOS EJES (4). LA RUEDA DENTADA INTERIOR (32) DEL ENGRANAJE PLANETARIO DE BIELAS ARTICULADAS (3) ESTA UNIDA DE MANERA SOLIDARIA CON LA RUEDA DENTADA RECTA DE SALIDA (31) CERCA DEL ENGRANAJE DE ENGRANE CONTINUO (310), A CUYO EFECTO ESTA RUEDA DENTADA RECTA DE SALIDA (31) SE SITUA INMEDIATAMENTE JUNTO AL ENGRANAJE PLANTERARIO DE BIELAS ARTICULADAS (3), UN PI ON LIBRE (G) ESTA DISPUESTO EN LA CPAA DE LA CAJA DE CAMBIOS (12) Y LA UNION (320) DEL BRAZO PLANETARIO (35) DEL ENGRANAJE PLANETARIO DE BIELAS ARTICULADAS, REDUCIDO (3) SE REALIZA A TRAVES DE LA RUEDA DENTADA RECTA DE SALIDA (31). MEDIANTE ESTA DISPOSICION MODIFICADA SE CONSIGUE UN MEJOR APROVECHAMIENTO DEL ESPACIO DISPONIBLE, Y SE AHORRAN PIEZAS DE UNION, LO CUAL PERMITE REDUCIR TAMBIEN EL PESO DEL ENGRANAJE.
