AMPHIBIOUS VEHICLE TRANSMISSION

摘要

Amphibious vehicle (2, Fig. 1) has retractable road wheels (8, Fig. 1) to allow planing. Power to road wheels (8) is disconnected automatically as the wheels (8) are retracted. This may be achieved through a cafe (310) attached to suspension rocker arm (232) to disconnect dog clutch (33, Fig. 6) attached to the input shaft of differential (34, Fig. 6) as the wheels (8) are retracted; and vice versa. Retraction device (242) - shown as a hydraulic cylinder (244) - rotates rocker arm (232) about pivot (240). This in turn retracts wheel suspension assemblies (224), link arms (220), and relay members (216) and (218). These pull up lower suspension arms (214), to which wheel hubs (204) are fitted. The system may be fitted to a steered axle; indeed, the retraction cafe system may be fitted to any suitable retractable suspension system. A suitable power train is shown in Figure 3.
