Pz. Kpfw. I Aus. A (Sd. Kfz. 101): Light Tank

Pz. Kpfw. I Ausf. A (Sd. Kfz. 101): Light Tank

This tank was evolved from the experimental model K-1 which appeared in 1934. Manufactured by the Krupp Company, both tanks were equipped with an air-cooled, four-cylinder, 65 horsepower gasoline engine, Krupp Model M305.

The turret is of horseshoe design, with flat front, the sides and rear being one rolled plate. The superstructure is octagonal with driver’s vision port on the left side of the front plate. Pistol ports are located on three corners of the fighting compartment. An exhaust silencer is placed on each track guard to the rear.

The suspension consists of four rubber-tired bogie wheels, adjustable trailing idler, front sprocket, three return rollers and outside center-guide steel track with dry pin. The idler and rear bogie wheel are paired to articulate on a stub axle. The two center bogie wheels are paired also. Quarter elliptic springs, assisted by a coil spring, absorb road shock. The front bogie is independently mounted and resisted by a coil spring plus a luvax shock absorber. Both articulating bogies are connected by a steel girder.

From the engine the drive is taken to the propeller shaft to the clutch, thence to the crash-type transmission, which is mounted forward on the right of the driver. There are 5 speeds forward and one reverse.

From the transmission the drive is taken through a bevel gear box to steering units of the clutch and brake type on each side. The two steering levers are each provided with two grips, one for normal steering and the other with thumb plunger which operates a “fly-off” type catch for holding the levers back and thereby providing a parking brake. No normal hand brake is fitted. From the steering units the drive is taken via two rubber disc-type universal joints to the final drive reduction gears, mounted inside the hull, to single sprockets driving from the front.
