Mercedes-Benz Unimog overview | Autocar


Within the mid-Forties, a tractor was a farmer’s lot. Two-wheel drive and with an uncovered and uncomfortable seat located over the rear axle, they have been rugged however gradual, and for those who needed to hold something, you wanted a trailer too. German engineer Albert Friedrich’s authentic Unimog ‘70200’ tore up that rulebook.

He made room for 2 occupants, aspect by aspect, above and behind the engine, protected by a windscreen and a canvas hood. He gave his machine four-wheel drive and portal axles – gears at every wheel, which push the axles increased than the wheel centres, for improved floor clearance.

Its monitor width was the dimensions of two rows of potatoes so might be pushed into fields, it might tow and it had an influence coupling for farming gear. However there was additionally a load mattress on the again and, with 25bhp, even the primary Unimogs might attain 31mph on the street – a pace that no tractor of the day might think about.

The ideas employed by Friedrich maintain true right now. The fashionable Unimog has a longitudinal engine up entrance, driving a 4WD system that makes use of portal axles simply as the unique did and locates its prop and half shafts inside tubes to guard them from rock strikes and dirt.

Issues have turn out to be extra subtle since, and greater, inevitably. Immediately, a Unimog has eight ahead gears and as much as eight reverse gears. It has three locking differentials, entrance, centre and rear, with any hydraulic traces or electrical cables working above the axle tubes, isolating them from harm too.
