The Tatra 30 is an automobile formerly made by the Czech manufacturer Tatra. It was manufactured between 1926 and 1928. From 1928 to 1931 the car was fitted with a newer engine and is therefore called the Tatra 30/52.
Design
Engine
Tatra 30
The Tatra 30 was powered by an OHV air-cooled four-cylinder boxer engine of 1679 cc, positioned at the front and giving a claimed output of 24 PS (17.6 kW). The maximum speed was around 90 km/h.[2]
Tatra 30 Sport
The Tatra 30 Sport was powered by an engine of a similar design, but with 1910 cc, which gave it 32–35 PS (23.5–25.7 kW). This version was capable of speeds up to 130 km/h.
Tatra 30/52
During the modernization process the "52" engine was fitted. It had 1911 cc and 22 kW (30 PS; 30 hp). This was a transitory mid-version before the production of the successor fully began. It was manufactured for a period of about one year.
The Tatra 30 was gradually modernized until it was replaced by the Tatra 52.
Backbone tube
Power was delivered to the rear wheels via a four-speed gearbox. The Tatra 30 featured a central backbone chassis, a hallmark of chief designer Ledwinka: the front axle was supported by a transverse leaf spring while a second transverse leaf spring supported the swing rear half-axle. The drive shaft was situated inside the backbone tube. The gearbox and engine are mounted in front of the backbone tube, while the differential is at the rear.[3]
Versions
The Tatra 30 was in the medium size category. Many different versions were made from four seat cabriolets to six seat limousines.
Differences from the Tatra 52
- The Tatra 30 has mechanical brakes, while the Tatra 52 has hydraulic ones.[3]
- The Tatra 30 is more angular, especially its fenders. A problem is that during the 1940s to 1960s, many cars were rebuilt, e.g. by the owner replacing a mechanical-brakes undercarriage for one with hydraulic brakes.[3]
