MTX (automobile)

MTX is an automobile that has been made in Czechoslovakia and now in the Czech Republic by MTX R5 sp.o.o of Prague since 1969. MTX is short for Metalex. Originally, it was a repair shop for Škoda racers.

The first single-seater racer ""MTX 1-01", appeared in 1970. During the 1980s, Formula Easter cars, autocross buggies and rally cars (based on Škoda and Lada) were produced. In 1989 - 1990 Skoda Rapid convertible was made in a few copies in cooperation with the German Heinzinger firm. In the 1990s, the company made 2 models: MTX Roadster (based on Škoda Favorit) and MTX Cabrio (based on Škoda Felicia). Super-sport model named MTX Tatra V8 was made in 1991.

Memotech MTX

The Memotech MTX500, MTX512 and RS128 were a series of Zilog Z80A processor-based home computers released by Memotech in 1983 and 1984. They were technically similar to MSX computers, but were not compatible.

Design

The MTX500 had 32 KB of RAM, the MTX512 had 64KB, and the RS128 had 128KB. Although the Z80A could only address a maximum of 64KB at a time, the MTX and RS128's extra memory, up to a maximum of 768KB, was accessible through the technique of page switching. All models had 32KB of ROM accessible in the first 24KB of address space. The extra 8KB of ROM was available through page switching. The ROM could be switched out entirely, allowing the full 16-bit address space to be used for RAM.

The computers featured an all-aluminium case and full size keyboard with real keys (unlike the chiclet keyboard used on the Sinclair ZX Spectrum). In addition to the standard (for the time) BASIC language interpreter, it included some other software:

Ford MTX-75 transmission

The Ford MTX-75 (Manual TransaXle), is a 5-speed transmission developed by Ford Motor Company for its larger-engined front wheel drive models. "75" refers to the distance in millimeters between the main and lay shafts.

Debuting in 1992, the transmission was developed in tandem with the Zetec family of engines. The transmission is optimised for transferring larger levels of torque than the older iB-series unit used on the Fiesta and Escort models. Other features include the provision of equal length driveshafts (to combat torque steer) and synchromesh on reverse gear.

The transmission was first used on the Zetec-engined Escort Mk V (only XR3i), but its proper intended application was on the Mondeo and its derivatives (the American Ford Contour, Mercury Mystique and the New Edge Mercury/Ford Cougar). 2000-2004 Focus with Zetec engine with manual used this transmission, as well as all diesel powered versions of the Focus.

The main change to the unit was to cable operation in 1996 on the facelifted Mondeo, as the rod-based linkage of the original unit attracted criticism for feeling vague and notchy.

Tatra 80

Tatra 80 is an automobile from Tatra designed by Hans Ledwinka in 1931. It was Tatra's flagship product at the time, powered by water-cooled 5991 cc V12 engine, including the familiar backbone chassis and swing axle suspension. With engine power of 120 bhp (89 kW) the car has top speed of 140 kilometres per hour (87 mph).

Tatra 17

Tatra 17 is a vintage automobile produced by the Czech manufacturer Tatra from 1925 to 1929. It was the company's top-end model which was sold alongside the economy car Tatra 12 and middle class Tatra 30.

Design

Engine

Originally, the car was fitted with a liquid-cooled six-cylinder OHC in-line Tatra 17 engine with 1,930 cc (118 cu in) and 35 hp (26 kW) power. The block was made from silumin and cylinder heads from aluminium. It was the first Tatra with an ignition battery. The maximum attainable speed of the 1,130 kg (2,491 lb) heavy car was 100 km/h (62 mph). Altogether 205 vehicles were made before 25 September 1926.

Another engine used was from even more up-market Tatra 31. It was also a liquid-cooled six-cylinder in-line OHC, however this time with 2,310 cc (141 cu in) and 39,4 hp (29,4 kW) power. The maximum speed was raised to 110 km/h (68 mph). 250 vehicles were made with this engine.

Tatra 17/31 was for some time manufactured alongside the successor model Tatra 31, of which 300 vehicles were made.

Tatra 111

The Tatra 111 was a truck produced in Czechoslovakia by the Tatra company.

History

The T111 was developed and manufactured during World War II as a heavy truck for use by the Wehrmacht. Production started in 1942 and continued for twenty years, ending in 1962 when it was replaced by the Tatra 138. Despite being built for the Nazi war machine, the vehicle ultimately played an important role after the war ended. The Tatra 111 contributed significantly to the rebuilding effort during the postwar era, mainly in Eastern Europe and the USSR. To its chief designer, however, it brought charges of treason and collaboration with the Nazi regime after the communist takeover of Czechoslovakia and contributed to the imprisonment of Tatra's design guru Hans Ledwinka.

Design and technology

The design was based on the proven Tatra concept of a backbone tube chassis construction with swing half axles, a modular gearbox and differential assemblies. The main advantages of the central load carrying backbone tube are its high torsion and bend strength, which protects the truck body against load stresses. The secondary advantage is that it houses all important parts of the drivetrain. Due to its torsional stiffness and use of differentials locks the vehicle had exceptional offroad capabilities. Of note was the ability to use a cranking handle to start the engine.
