Abstract
Sistema de propulsión hidrostática para dumpers similares. Dispone de bombas hidráulicas que están conectadas a un matar principal (2) de gasolina o diesel, y matares hidráulicos que accionan las ruedas. Incluye cuatro motorreductores hidráulicos (6, 7, 8 y 9) con dispositivo de frenado y estacionamiento, anejos a las ruedas del vehículo. Existen dos circuitos hidráulicos paralelos en los que intervienen respectivas bombas hidráulicas (3, 4) conectadas a la toma de fuerza del motor principal (2), girando a la vez. Estas bombas hidráulicas (3, 4) envían el caudal de aceite a los motorreductores delanteros (8, 9) y traseros (6, 7), estando dichas bombas hidráulicas (3, 4) comandadas por servocontroles de pedal (10, 11) para las marchas adelante y atrás respectivamente. Los circuitos de cada bomba (3, 4) están conectados en paralelo mediante reguladores de caudal (12, 13) para compensar el mayor o menos esfuerzo de cada rueda, con función de un diferencial convencional.
