Электролюкс евт 815 запчасти

Tatra T815 is a truck family, produced by Czech электролюкс евт 815 запчасти Tatra. It uses the traditional tatra concept of rigid backbone электролюкс евт 815 запчасти and swinging half-axles giving independent suspension. The vehicles are available in 4x4, 6x6, 8x8, 10x8, 10x10, 12x8 and 12x12 variants.

There are both air-cooled and liquid-cooled engines available with power ranging from 230–440 kilowatts (310–590 hp). As a successor to Tatra T813 it was originally designed for extreme off-road conditions, while nowadays there are also variants designated for mixed (both off- and on-road) use.

The T815 and its descendant models took электролюкс евт 815 запчасти Czech truck racer Karel Loprais to victory six times in the Dakar Rally.

History[edit]

Designed to eventually replace T148 the prototype T157 was introduced in 1970 and several more prototypes were designed between 1970 and 1974 period but no production resulted.

Due to protests from another Czech manufacturer LIAZ which was assigned by the government central planning committee to manufacture trucks of similar class Tatra dropped the T157 and instead started to concentrate on a heavier class as the replacement for T813 and T148 which was introduced in 1983 as T815 series.

In 1989 Tatra modernized T815 series электролюкс евт 815 запчасти introduced new T815-2 which received further upgrade in 1994 and just 3 years later in 1997 the new cabin TerrN°1 is introduced. Another facelift followed in 2000 where changes included among others new instrument panel and cab attachment and for the first time there is an option for fitment of liquid-cooled engines.

The latest facelift of cabin came in July 2010. Due to emission электролюкс евт 815 запчасти changes in 2003 Tatra developed all new V8 engine T3C to comply with Euro III where it followed the tradition once again with its air cooling design. The further developed T3D engine was introduced in 2006 with its SCR and Euro IV compliance.[4]

Design[edit]

See also: backbone chassis

While most other manufacturers derive their trucks from road applications, Tatra T815 was purposely designed for extreme off-road conditions, and its road versions are derived from the off-road original concept.

The principle consists in a central load-carrying tube with independently suspended swinging half-axles bolted as one whole. This gives Tatra vehicles outstanding driving qualities in the most difficult terrains.

The concept allows higher off-road speed compared to classical электролюкс евт 815 запчасти axle design.

Central load-carrying tube[edit]

The primary structural feature of Tatra trucks is the central load carrying tube, also called a backbone frame.

All other parts of the truck are mounted to this rigid assembly. The inherently high torsional and flexural rigidity of this layout protects superstructures from the motions and forces on the axles. Torque distribution to the axles is also carried within the backbone.[5]

Differential[edit]

Tatra differentials[6] are a unique design that uses two opposing spiral bevel gears instead of the usual single set.

The differential gears are part of the input drive shaft rather than between the output axles as in a conventional differential.

электролюкс евт 815 запчасти

All versions of the Tatra differential have locking pins that can force the differential gears to rotate together, “locking” the differential.

This arrangement had two distinct advantages. The first is that the dual output bevel gears allow the axles to swing around the drive axle without the need for universal couplings. The second is that the input drive shaft goes essentially straight through the differential электролюкс евт 815 запчасти, allowing simple coupling to a second set of swing axles. This modular design enables configurations of 2, 3, 4, 5, or even 6 axles with all axles driven. The whole электролюкс евт 815 запчасти is part of the backbone frame.

Suspension[edit]

Front[edit]

  • Mechanical suspension[7] of load capacity up to 8 tons per axle by torsion bars – электролюкс евт 815 запчасти versions with one steered front axle (4x4 and 6x6) or by leaf springs – for versions with two steered axles (6x6, 8x8, 10x10 or 12x12).
  • Air-bellows, with a load capacity of 9 tons per axle and a possibility of a ground clearance regulation.

Rear[edit]

  • Mechanical – by leaf springs, with a load capacity of up to 11.5 tons per axle[8]
  • Air-bellows with a load capacity of 10 tons per axle and a possibility of a ground clearance regulation
  • Tatra King Frame suspension system - combination of an air-bellow with a coil spring placed inside, with a load capacity of up to 11.5 tons per axle or combination of air-bellows with leaf springs, with a load capacity of 13, 15 and 16.5 tons per axle.

All suspension types are equipped with telescopic shock absorbers; some versions also have stabilizer torsion bars.

Engine[edit]

The Tatra engine[1] is an air-cooled, OHV, currently 12.7 litre 90° V8 120 x 140 mm diesel engine with direct fuel injection.

It is turbocharged by one Holset WasteGate turbocharger, and equipped with an intercooler placed directly over the engine. The engine is equipped with a mechanically controlled in-line Bosch injection pump. Its roller crankshaft bolted together from individual электролюкс евт 815 запчасти belongs among unique technical solutions.

The engine is available in emission specifications Euro 2 - Euro 5 with power output ranging from 230 to 325 kilowatts (308 to 436 hp) and 1,400–2,100 N⋅m (1,000–1,500 lbf⋅ft) torque. Originally was the T 815 truck optionally powered by электролюкс евт 815 запчасти same range V10 (15.8 litre) and V12 (19 litre) air-cooled Tatra engines without turbo and intercooler or by biturbo V12 until the Euro 1 emission limits.

Tatra T815 can be fitted also with water-cooled engines made by other manufacturers - notably Cummins and Deutz with power ranging from 260 to 440 kilowatts (350 to 590 hp) with 1,550–2,750 N⋅m (1,140–2,030 lbf⋅ft) torque.

The most powerful MTU engine that was used in a T815 prototype tank prime mover had 610 kilowatts (820 hp) displacing 21,930 cc.

Transmission[edit]

  • Manually controlled mechanical Tatra transmission[3] which is mounted directly on the auxiliary transmission case, and which, therefore, is an integrated part of the chassis with 10 or 14 gears with two auxiliary gears.
  • An electronically controlled gear shifting Tatra - a driver using a joystick just pre-sets a speed gear, and after the clutch is engaged, the speed shifting is carried out.

    The driver is informed about the shifted speed gear by means of электролюкс евт 815 запчасти dashboard display.

  • Twin Disc which is a six-gear auto transmission of 1189 or 1177 type
  • Allison six or seven-gear automatic transmission with a compact construction in one case, with a torque converter, which are mounted directly on the электролюкс евт 815 запчасти T815 электролюкс евт 815 запчасти equipped with own Tatra-produced COE cab.[9] There is basic version, extended version with room behind seats used for a berth and especially for fire-fighting applications a long four-door cab enabling transportation of up to six persons.

    There is also special low cab version used mostly for cranes and other special applications.

    The cab is situated in front of the front axle.

    Equipment[edit]

    • Trucks equipped with air-bellows suspension have possibility of a ground clearance regulation.
    • Special protective surface finish
    • Central tyre inflation system enabling deflation/inflation of tyres during the drive in boggy terrain (standard for military versions, on demand for civilian)
