History

The first prototype already built in 1960 utilized existing Tatra T138 assemblies in 4x4 full time all wheel drive, which was also another first for Tatra. A prototype is an original type form or instance of something serving as a typical example basis or standard for other things of the same category Year 1960 ( MCMLX) was a Leap year starting on Friday (link will display full calendar of the Gregorian calendar. The Tatra T138 was a Truck produced in Czechoslovakia by the Tatra company A permanent full-time job usually has benefits (such as health insurance however temporary full-time jobs usually do not have benefits Four-wheel drive, 4WD, or 4x4 ("four by four" is a four-wheeled Vehicle with a drivetrain that allows all four Wheels to After the initial trials however the designers decided to develop and expand the concepts onto 8x8 all wheel drive all terain vehicle. Eight-wheel drive, 8WD, or 8x8 ("eight by eight" is an eight-wheeled vehicle with a Drivetrain that allows all eight wheels to receive power Four-wheel drive, 4WD, or 4x4 ("four by four" is a four-wheeled Vehicle with a drivetrain that allows all four Wheels to Vehicles, derived from the Latin word vehiculum, are non-living Means of transport. The basis of the design thus became modular chassis of T813.

Design and Technology

The tubular backbone construction was once again selected. The main advantages of central load carrying backbone tube are in its high torsion and bend strength protecting truck body against load stresses. The advantage is also that it houses all important parts of the drive train as well as it enables a concept of modular construction where designers and customers can specify 4,6,8, wheel drive and various length wheelbase combinations. A wheel is a circular device that is capable of rotating on its axis facilitating movement or transportation whilst supporting a load ( Mass) or performing labour in machines In both road and rail Vehicles the wheelbase is the distance between the centers of the front and rear wheels The new cab of COE design was implemented as were the wide profile super single tyres and central tyre inflation /deflation system. This article is about tires used on road Vehicles including pneumatic tires and solid tires.


Engine

The "monstrous" naturally aspirated V12 T-930 was created by adding extra four cylinders to the existing T-928 75 degree V8 engine used in Tatra T138. An engine is a mechanical device that produces some form of output from a given input A naturally-aspirated engine or normally-aspirated engine (or "N/A" - Aspiration meaning breathing refers to an Internal combustion engine V12 redirects here For the V12 Training program see V-12 Navy College Training Program. A V8 engine is a V engine with eight cylinders mounted on the Crankcase in two banks of four cylinders in most cases set at a right angle to each other The Tatra T138 was a Truck produced in Czechoslovakia by the Tatra company The crankshaft consisted of six individual journals bolted together with front and rear pins all running on the main roller bearings and located on axial friction thrust washers. The crankshaft, sometimes casually abbreviated to crank, is the part of an Engine which translates reciprocating Linear Friction is the Force resisting the relative motion of two Surfaces in contact or a surface in contact with a fluid (e Thrust is a reaction force described quantitatively by Newton 's Second and Third Laws. The military version was once again multi-fuel capable, running on mixtures of diesel fuel, petrol and aviation kerosine fuel. A military is an Organization authorized by its Nation to use force usually including use of Weapons in defending its Country (or by attacking Diesel or Diesel fuel (ˈdiːzəl in general is any Fuel used in Diesel engines The most common is a specific fractional distillate of petroleum Aviation refers to activities involving man-made flying devices ( Aircraft) including the people organizations and regulatory bodies involved with them Kerosene, sometimes spelled kerosine in scientific and industrial usage is a Combustible Hydrocarbon liquid Fuel is any material that is burned or altered in order to obtain energy

Chassis

Full length backbone tube with independent swing half axles in 4x4, 6x6 and 8x8. A chassis (plural "chassis" (ˈʃæːsiː ˈtʃæːsiː consists of a framework that supports an inanimate object analogous to an Animal 's Four-wheel drive, 4WD, or 4x4 ("four by four" is a four-wheeled Vehicle with a drivetrain that allows all four Wheels to Six-wheel drive, 6WD, and 6x6 are terms used to describe a Drivetrain which allows all six wheels to receive power from the vehicle's engine simultaneously On 4x4 models front axle suspension via adjustable torsion bars , 6x6 and 8x8 models front and rear axles suspended by longitudinal semi-elliptic leaf springs. Suspension is the term given to the system of springs, Shock absorbers and linkages that connects a Vehicle to its Wheels Suspension An axle is a central shaft for a rotating Wheel or Gear. In some cases the axle may be fixed in position with a bearing or Bushing Originally called laminated or carriage spring, a leaf spring is a simple form of spring, commonly used for the suspension in For 4x4 configuration rear axle was suspended via the airbags suspension. An airbag is part of a vehicle's safety restraint system a flexible envelope designed for rapid inflation in an automobile Collision, to prevent vehicle occupants Full time all wheel drive front twin steer (6x6, 8x8) drive via homo-kinetic drive shafts, drive with the differential locks ,inter-axle differentials with locks and planetary hub reductions on all models. Four-wheel drive, 4WD, or 4x4 ("four by four" is a four-wheeled Vehicle with a drivetrain that allows all four Wheels to Reductions (known as Reducciones de Indios, or simply Reducciones in Spanish; also Congregacíones) were settlements

Transmission

The main gearbox was located behind the cabin and connected to an engine clutch housing via short cardan shaft( this design enables a so called flat floor cabin) was bolted together with an auxiliary gearbox to a transfer case and then to a backbone tube and formed main part of a chassis structure. In both road and rail Vehicles the wheelbase is the distance between the centers of the front and rear wheels Ride height ( ground clearance or simply clearance is the amount of space between the base of an automobile Tire and the underside of the Chassis; or more A transfer case is a part of a Four wheel drive system found in four wheel drive and All wheel drive vehicles Options for the rear power take off and or a winch drive were available. A power take-off ( PTO) is a splined Driveshaft, usually on a Tractor or that can be used to provide power to an attachment or separate machine A winch is a mechanical device that is used to pull in (wind up or let out (wind out or otherwise adjust the " Tension " of a Rope or Wire rope Main and auxiliary gears were fully synchronized except the first and reverse gear. The new feature was unique 2 speed planetary overdrive system bolted between front and rear axles. An axle is a central shaft for a rotating Wheel or Gear. In some cases the axle may be fixed in position with a bearing or Bushing The overdrive could only be selected manually whilst stationary. Auxiliary gearbox had a neutral position which allowed a winch and a power take off to use main gearbox gearing for variable speed operation. The final drives used Tatra gear differentials with locks, offset drive shafts and planetary hub reductions.


Brakes

Full triple circuit air "S" cam drum brakes acting on all wheels drums via slack adjuster, all brake cylinders were remotely vented. A brake is a device for slowing or stopping the motion of a Machine or Vehicle, or alternatively a device to restrain it from starting to move again Air brakes are used in Trucks Buses trailers, and Semi-trailers. A drum brake is a Brake in which the Friction is caused by a set of shoes or pads that press against the inner surface of a rotating First brake circuit acts on front wheels , the second on rear wheels and the third controls trailer service brakes. Unique design feature was remotely mounted brake valve which was operated via hydraulic master and slave cylinder principle on the Hauler 6x6 or via mechanical linkage on 8x8 models.

Bodywork

Cabin is all steel construction of COE design but not tiltable, the access to the engine was provided via removable engine cowlings inside the cabin compartment. Since diesel engines lack a throttle valve on the intake manifold there is no intake vacuum when the engine is not fueling In Automotive engineering, the bodywork of an Automobile is the structure which protects The occupants Any other payload Cab-over, also known as COE (Cab Over Engine cab forward, or forward control, is a body style of Truck or Van that has a vertical An engine is a mechanical device that produces some form of output from a given input A cowling is a covering of a vehicle's Engine, most often found on automobiles and aircraft The cab came in two versions, the "short" two seater two door version and in the "long" "crew cab" seven seater four door version. Crew Cabs are an extended cab bodystyle commonly found on Utes or Pickup trucks This cab design typically has forward-facing rear seating and four The military specs cabs included the roof hatch or two in the case of the crew cab. A trapdoor is a door set into a floor or ceiling (depending on what side of the door one is on All cabs were equipped with self contained diesel cab heater which could also be used in the winter to warm up the engine before starting it. Another military feature was CTI central tyre inflation system controlled from the cab for each wheel independently and an ability to pressurize gearbox and differentials housing during water crossing. The 8x8 models had abilility to cross trenches up to 1. A trench is a type of excavation or depression in the ground Trenches are generally defined by being deeper than they are wide (as opposed to a wider Gully or Ditch 4 metre wide and vertical obstacles up to 0. 6 metre high. Water crossing depth (static including the wave) was up to 1. 4 metre (KOLOS 8x8). The vehicle top speed was 92 km/h (NT & NTH), 80 km/h (KOLOS), 70 km/h (hauler), 60 km/h (S1) @ 2000 engine rpm.
