Tatra 805 is a light off-road truck manufactured by Tatra
(later AZNP Mladá Boleslav, Races of V. Lenin Plzeň and
Avia Prague) between 1952 and 1960. It was developed
especially for the needs of the army on the basis of a special assignment.
The army demanded a car capable of riding in heavy
terrain and with high traction power. The Tatra 805 was powered
by a gasoline 8-cylinder air-cooled T 603 A engine. The engine
had a 2545 cc (75 mm stroke, 72 mm stroke) and 75 horsepower
at 4000 rpm. The gearbox was a four-speed gearbox and was
coupled with a two-speed additional transmission. The cars had
a steady rear axle drive, the front axle drive could be fitted with a
special shift lever. The drive was still equipped with a differential
lock. The chassis of the Tatra 805 was made up of a spine frame,
which was coupled to the front and rear axles. The axles were
swinging, with wheel reductions, which made it possible to reduce
the half-axle load, increase the vehicle’s light height, increase the
overall gear ratio and thus maximize the traction forces. One-circuit
hydraulic drum brakes were without power. The braking effect
was inadequate, mainly due to the braking of the loaded vehicle
at higher speeds, or the heaviness of the downhill descending
when the braking effect of the engine was insufficient. Tatra 805
was a typical truck of the Czechoslovak People’s Army. The most
widespread version was a flatbed and vehicles from various cabin
bodies (radio, ambulance, fire truck). From the special versions, it
was a tank or lightweight vehicle with a canvas roof for the paratroopers.
Tatra 805 - RM-31Ma “Třinec” was a mobile shortwave
radio station, used for radio links within a band, artillery groups
and to connect with explorers. On the chassis of the Tatry 805
was built a light armored vehicle OA-82 Jarmila. Perhaps the most
famous Tatra 805 are silver-red and silver-blue painted specials
for the famous Zikmund and Hanzelka travelers
