[烛光生存狂]-The Vollkettenaufklarer 38(t) [技术性问题]

Auto-Union

In late 1943, Heereswaffenamt Wa.Pruf-6 asked Auto Union to develop a light, fully tracked reconnaissance vehicle, capable of carrying 6-8 men in an open-top superstructure. The vehicle was designed to attain speeds in excess of 50 km/hour and was to be lightly armored.

1943年末,陆军兵器局第6兵器测试处(Heereswaffenamt Wa.Pruf-6)要求Auto Union研制一种轻型全履带侦察车,顶部敞开可以装载6-8人.车辆设计时速要求可以达到50公里/小时,采用薄装甲防护.

Auto Union first built a wooden mock-up, and after the layout was approved, in early 1944 constructed two prototypes for evaluation.The vehicle had an open top, with the engine in the back and the powered front sprockets. The driver sat on the left, and next to him was a machine gun in the usual "Kugelblende". In the vehicle were two long benches for the rest of the crew.

The engine used was the Maybach HL 50Z of 5,000 cc displacement and 200 HP(147.8 kW) output. It was squeezed into the left rear of the vehicle, to make room for the crew door, which was on the right side of the rear plate.The armor was fairly light, 30 mm front and 14.5 mm sides and rear.

The carriage(suspension) consisted of five overlapping wheels on each side with a torsion bar suspension, and the tracks were from PzKpfw IV. The gear-box was hydraulic. The prototypes were tested in the summer of 1944 on the testing track and were well liked for both their layout and their mobility. Problems were encountered with the gear-box. Therefore, and also because of the decision of September 1944 to limit all new constructions to two chassis only, namely the Panther and 38(t), it was eventually decided to order a prototype from BMM in Prague(布拉格), maker of the Jagdpanzer 38 Hetzer.

BMM

Ihe WaPruf-6 Pz.la ordered two prototypes from BMM on September 6,1943. They were sup- posed to be based on the PzKpfw 38(t)nA. One was planned with the Tatra(太脱拉)103 Diesel engine, and one with the Praga NR engine with an output of 280 HP.

The prototypes were built in 1944. They were wider than the Auto Union model and heavier, being much better armored. Their front plate was 50 mm, sides 30 mm and the rear plate 20 mm thick. They retained the general layout with the open top and the engine in the rear, but disposed with the Kugelblende for the front machine gun, which was instead mounted behind an armored shield as carried by the SdKfz 250/251 halftracks. A rear mount for another machine gun was also provided.

The new Tatra 103 twelve cylinder air-cooled Diesel put out 220 HP( 162.6 kW) at 2600 rpm, giving the vehicle a maximum speed of 64 km/hour on roads. Enough fuel was carried for endurance up to 600 km. The suspension used the well-tested layout of the PzKpfw 38(t), and the Praga-Wilson gear-box was used.

The BMM "Katzchen"(Little Cat) was clearly a better design than the Auto-Union one, being better armored and faster. The use of the Diesel engine made it probably also safer for its users. If manufactured in quantities, it would have proven to be not only a suitable reconnaissance vehicle, but also a good armored personnel carrier as well. The fate of the two prototypes after the end of the war is not known, but the Czech army clearly was not interested in their further development.
