The Goliath Jagdwagen type 31 ( truck 0.25 t gl (4x4) , Goliath type 31 ) was a planned military vehicle of the Bundeswehr.
History of Development
At the beginning of 1953, the Koblenz office, headed by Secretary of State Theodor Blank , asked To determine the later Defense Minister, the Association of the German motor vehicle industry, which companies in the automotive industry are able to develop vehicle types and models and, if necessary, to manufacture at a later date. As a result of this inquiry, various automotive engineering projects have been launched in the automotive industry. Public funds for these tasks were initially unavailable. Among other things, there was a desire in the small class (1/4 t) to build a lightweight, all-terrain vehicle as a replacement for the used in World War II motorcycle with sidecar for military purposes. Among other German manufacturers, the company Borgward applied for the project in this payload class.
Already in July 1954, a prototype was presented at a comparative testing on Westerland. This open Kübelwagen was equipped with a water-cooled 2-cylinder injection engine, which made about 42 hp. The capacity was 889 cc. The transmission was very reminiscent of that of the competitor of the Auto Union GmbH. The wheelbase was about 2200 mm. The prototype had a turn-off four-wheel drive. Conspicuous were a much too low slope angle and a cooling system behind the engine. In another performance in December 1954, it was assumed that an engine power of about 45 hp. In January 1955, the first comparative testing of all SUVs took place in Bonn, at the Borgward was represented with a car in sheet steel design and two vehicles with an aluminum body. These vehicles were equipped with 5-hole rims of the dimension 7.00 × 16 and tires of size 200-16. With a length of 3570 mm and a width of 1660 mm resulted in a total weight of 1500 kg. For the first time, the alternator delivered 300 watts at a voltage of 24 volts.
The vehicle was of a longitudinally mounted 2-stroke - injection engine with two cylinders from the Goliath GP 900 E is driven, a power of 29 kW (40 hp had) and the vehicle to a maximum speed of 90 km / hhelped. The payload of the vehicle was 500 kilograms. For the off-road mobility continued to provide a switchable rear-wheel drive and a fully synchronized 5-speed gearbox without reduction with an intended as off-road gear, extremely short first gear. A distributor differential was not provided. The front wheels were hung on lower wishbones and an upper transverse leaf spring and were steered with a rack and pinion steering. Rear was a rigid axle built-in leaf springs. The climbing ability was given as 60%. The Type 31 had 235 mm ground clearance and a wading abilityof 500 mm. The body of the car was in an open design with hood and without doors. She sat on a ladder frame. The first prototype of 1954 had a one-piece windscreen, trough-shaped "bucket seats" (see: Kübelwagen ), Winker and two beads on the flanks.
Both at the comparative demonstration in January 1955 and in other demonstrations convinced the Goliath SUV not. He got stuck several times in the test area, lost parts of his exhaust system in the area and was hampered by the extremely low ground clearance strong against his competitors.
For the comparative testing at the Federal Border Police in Lübeck Goliath had reworked, the ground clearance significantly increased and widened the body. Despite all this, this car could not convince. Hinge joint fractures of the axles occurred more frequently in the field, gearbox damage arose during the demonstration, the steering wheel turned out to be completely inappropriate. Substantial deficiencies showed the Goliath against the competition from the house Auto Union . Also in the second Lübeck testing in the autumn of 1955, the competitor convinced considerably more. On January 20, 1956 Goliath delivered with considerable delay twelve optimized pattern vehicles who were barely able to take part in the comparison test due to the passage of time. These vehicles had a reinforced body, turn signals as direction indicator and headlight guards. Technical defects caused numerous failures. Furthermore, the vehicles should be eaten again and again in off-road driving
A Goliath vehicle was towed by the DKW SUV. In the field report of the teaching staff Andernach the shortcomings of the Goliath were listed. Undoubtedly, the Auto-Union off-road vehicle also performed significantly better here. Low trial and test phases and many shortcomings contrasted with the hitherto lowest development costs (spring 1956).
At the joint meeting of the Defense Committee and the Budget Committee in May 1956, it was decided to carry out further trials of the three brands. Orders were placed with Auto Union GmbH for more than 5000 units and 50 pieces each for Porsche and Goliath. Like the Jagdwagen the competitor Porsche was Type 31 procured only for testing experiments, while the Auto Union presented in the development time their model for foreign armed forces and offered in neighboring countries export vehicles. The Auto Union GmbH was much more agile. The Bundeswehr received a total of 50 units of this type; Thus after the Andernacher test 38 vehicles were to be re-delivered.
He was in contrast to 1957 subsequently filed Goliath type 34 as technically immature , and because of the lack of center differential of the drive train was so rigid, that when the troops Try rows of teeth of Teller and bevel of the rear axle broke. Instead of the type 31 , the Munga model of the Auto Union was selected for the Bundeswehr.
The significantly improved Type 34 with four-stroke engine was in the body variant with 2000 mm wheelbase in April 1958 the Bundeswehr for testing purposes provided. After 600 km, the car had to be shut down due to engine damage; a valve spring was broken. The vehicle with the chassis number 34.0100 01 then again on May 10, 1958 an accident in the test phase and had to be repaired at the factory. Thereafter, the test was discontinued.
The total purchased 50 Goliath SUVs remained until the segregation in the troop.
