Abstract
Dispone de bombas hidraulicas que estan conectadas a un motor principal (2) de gasolina o diesel, y motores hidraulicos que accionan las ruedas. Incluye cuatro motorreductores hidraulicos (6,7,8 y 9) con dispositivo de frenado y estacionamiento, anejos a las ruedas del vehiculo. Existen dos circuitos hidraulicos paralelos en los que intervienen respectivas bombas hidraulicas (3, 4) conectadas a la toma de fuerza del motor principal (2), girando a la vez. Estas bombas hidraulicas (3, 4) envian el caudal de aceite a los motorreductores delanteros (8, 9) y traseros (6, 7), estando dichas bombas hidraulicas (3, 4) comandadas por servocontroles de pedal (10, 11) para las marchas adelante y atras respectivamente. Los circuitos de cada bomba (3, 4) estan conectados en paralelo mediante reguladores de caudal (12, 13) para compensar el mayor o menor esfuerzo de cada rueda, con funcion de un diferencial convencional. Los motorreductores hidraulicos (6,7,8 y 9) incluyen dispositivos mecanicos manuales (15) de desbloqueo para posibilitar el remolcado en caso de averia.
