Trippel S.G. 6 Schwimkraftwagen: Amphibious 1/4-ton Truck, Model 1942

Trippel S.G. 6 Schwimkraftwagen: Amphibious 1/4-ton Truck, Model 1942

Development of this vehicle began prior to 1939 at the Trippelwerke Hamburg Saar. According to German press reports, in 1941 Mr. Hans Trippel, the inventor, made improvements over his earlier models as a result of experiments and his plant prepared to go into mass production. The above vehicle was manufactured in 1942. Field examination shows that the application of its design to combined land and water transportation is successful. Simplicity of design throughout makes it possible to produce the vehicle in large quantities very easily.

The body is arranged with a front engine compartment, a center crew compartment, and a rear stowage compartment. Water sealing is accomplished by means of rubber seals throughout. The only openings in the rear of the body are for the wheel and propeller drive and for the shafts of the shock absorbers. In the front of the body there are three openings on each side as follows: one for the shock absorber rod, the radius rod, and for the wheel drive.

Four-wheel drive with independent double coil spring suspension contributes to the cross-country mobility which is said to be remarkable. The shock absorbers are mounted inside the hull and connect with the suspension through an auxiliary shaft that is stuffing box sealed.

A special transmission is provided with three speeds forward and one reverse for highways plus three speeds forward and one reverse for cross-country and a forward and reverse gear for operation in the water. The three-bladed propeller is lowered to position when in the water and is protected inside the body work when on land. Steering is accomplished by front wheels. A one-shot lubrication system is operated from the dash.

Kfz. 2 S: Amphibious Volkswagen

Kfz. 2 S: Amphibious Volkswagen Schwimmwagen

The basic construction of this vehicle is identical with that of the standard type 82 Volkswagen. Front wheel drive has been added to the ingenious positive lock differential rear drive already employed and removes all objections to its poor cross-country performance.

The steering assembly and the front wheel suspension are placed outside a watertight bulkhead.

A rubber sealed stuffing box is used for the front wheel drive shaft. In the rear the suspension is mounted outside the watertight hull. The only openings are for each drive shaft. These are entirely hooded by two bellows type rubber boots that sheath the axle allowing movement in all directions.

Shock absorbers are provided for each wheel. In the front they are mounted outside the hull. In the rear, a watertight shaft extends through the hull from shock absorber to wheel.

Normal grease seals on the rear axle keep water from seeping into the differential and transmission assemblies.

The transmission, transfer case and the positive locking differential comprise a unit assembly secured to the floor at its extreme rear end. A power takeoff has been added to the normal transmission to provide front wheel drive. A cross-country gear position is also provided. It is an extra low gear necessitating the normal transmission be kept in neutral position when used.

The clutch is a dry single disc foot operated type. The propeller assembly is mounted on a spring-loaded hinge that is positioned in the rear directly in line with the hand crank pulley. It incorporates a slip clutch to eliminate damage to the propeller blades by underwater obstructions. Engagement direct with the engine is made through a dog clutch sealed by a rubber bushing on the engine side.
