Iata ce am gasit!
Estepe mecanica de Vw Broscuta!
Stiam de existenta sa, dar prima data, cand vat poze asa de detaliate cu asa ceva!
M-am gandit, ca trebuie neaparat s-o vedeti si voi!

super...dar cat costa
am vazut odata un documentar despre ele pe discovery,in urma cu 2 ani.

Kettenkrad, jumate automobil senilat, jumate motocicleta

Oare, Kettenkradul cum se conduce?
Din ghidon sau din manete, ca senilatele?
Cred ca avea ceva directie mixta, ca altfel ar fi greu de manevrat!

[Elijah]

chiar, buna intrebare. Banuiesc ca asa cum sugerezi, mixt. Dar nu cred ca din manete ci mai degraba din pedale....Ar fi complicat sa tii si ghidonul si manetele la viraje

Niste date tehnice cu dracia asta, unde pot gasi?

Technical Data of the NSU Kettenkrad
The Kettenkrad was designed as a small tractor (prime mover) to tow a trailer or a small gun (20 mm AA or 3,7 cm AT).
It carries a crew of three soldiers. The driver and two passengers. The passengers are facing backwards.

The Kettenkrad is not armo(u)red and not armed. Some versions have three riffle holders to carry the riffles of the crew.

(The first 500 Kettenkrads and all postwar Kettenkrads had a standard OPEL (System Carter) carburetter)
 
Electrical system: (Thanks god, it's BOSCH!)
Voltage 6 Volts, negative ground
Generator 6 Volts, 75 W
Battery 6 Volts, 75 Ah

Suspension:
Front wheel 3.50-19 (Air pressure: 1,7 atü = 25 psi)
Tracks Zpw 51/170/120, 40 links per track
Track pads W02
Wheels Road wheels 450 mm diametre, Leitrad 410 mm diametre. (Very early Kettenkrads have bigger Leiträder)

The engine comes from the well known OPEL OLYMPIA car. NSU was a motorcycle factory and produced only one cylinder engines with up to 600 ccm, which were not powerfull enough for the Kettenkrad. To save the work and the time for the developing of an own engine, NSU took the reliable OPEL engine from the stock. The OPEL OLYMPIA car was in Wehrmacht use, too, so the mechanics in the field knew the engine.

Gearbox:

Gearbox with 3 forward gears and 1 reverse gear, plus transfer box for "Gelände" (Off-road) und "Straße" (Road). So in total there are 6 forward and 2 reverse gears.

Fuel consumption:

On the road: 16 litres/100 km (18 mpg (imperial))
Off road: 22 litres/100 km (13 mpg (imperial)) and more, depending on the terrain.

The fuel tank capacity is 2 x 21 litres. So each of the two fuel tanks can take a full jerrycan. The fuel tanks are located to the right and to the left of the driver.

Se pare ca roata ii asigura stabilitatea la viteze mari, la offroad adica la viteze mici de deplasare, nefiind necesara.
Uite schema directiei!

[Misi din Cluj]

Interesant si ingenios!
Directie cu ajutorul a doua frane cu banda.
Oare cat timp tin ferodourile alea.
La mine pe Aro 10, frana de mana actioneaza pe cardan, printr-un dispozitiv asemanator. La Gaz 69 si Uaz la fel, tot asa ceva!

Interesanta comparatie intre Vw Schwimmwagen si Gaz 46MAV.
Intre ele, titusi exista o diferenta de 20 de ani.
Gazul 46, pare sa pluteasca mai bine.
La o astfel de masina intrebarea pricipala este ca pluteste sau se duca la fund?
