eMercedesBenz Feature: First With A Propeller Drive Debuts In 1908

The car without chain or belt: The 35 hp of 1908 (named 22/35 hp from 1909) was the first car” – car with propeller drive – of Daimler-Motoren-Gesellschaft.

In the spring of Daimler-Motoren-Gesellschaft (DMG) launched the new 35 hp – Daimler’s first car with shaft drive. This of power transmission from the to the driven axle via a shaft universal joints was the most innovation of the new Mercedes model. The by contrast, was adopted in almost form from the previous 35 hp with chain drive. It of two rows of cylinder pairs in line, and it had lateral camshafts and valves.

From 1908, the 35 hp advertised as “cardan car” in the gradual replacement of power by chains between engine and at DMG. However, chain was to remain in the range of the Stuttgart-based parallel to propeller shaft for several years to come. In heavy and powerful cars to be fitted with chain which was considered to be more

From belt drive to shaft

Propeller shaft today the standard in automotive was one of three alternatives in the early of the automobile, alongside belt and chain drive. In Daimler’s carriage of 1886, power was still performed by both a belt (from engine to and chains (on to the ring gears on the axle). The engine of the wire-wheel car of even acted directly on the wheels. In 1895, finally, belt-driven car made its debut. In car developed by Wilhelm Maybach, a transmission conveyed the power of the Phoenix engine to the rear

The Daimler Phoenix of 1897 was the chain-driven automobile developed by and Daimler. DMG had already been the so-called Schroedter car with drive since 1892, but car was built at a time when and Daimler worked at the Hotel independently of DMG. In the following chain drive became the for transmitting power from the to the axle.

Robust lightweight with little comfort

The hesitant advance of propeller drive as the successor to chain was due to mechanical problems in the first of the 20th century. Power by means of an axis with joints at one or both ends was in that it was robust, light and maintenance-free, but the clearly stiffer between axle and engine as to the chain caused strong which adversely affected comfort for the passengers.

The advantages of the new technology prevailed and numerous manufacturers started to car with propeller shaft at the turn of the century. In this Benz Cie. was five ahead of DMG. As early as the Benz Parsifal was the brand’s car with propeller shaft to come onto the market. the two-cylinder models with 8, 10 and 12 hp 7.4 and 8.8 kW) and propeller shaft drive, the also included a 16-hp model (11.8 kW) with drive. Continuous further of the propeller shaft drive growing acceptance for this of power transmission.

Development of the “cardan car”

After the of the 35 hp Mercedes with propeller drive in 1908, the car was given a new designation – 21/35 hp – in 1909. The figure indicates the tax horsepower, the figure the actual power from a displacement of 5.3 liters. In the year, … was increased to the output of the successor model to hp from a displacement of 5.6 liters. was enlarged once again – to 5.7 – in 1913. The car, now designated hp, was powered by a four-cylinder in-line with cylinders arranged in and developing 50 hp (37 kW).

Initially, propeller shaft was used only for the lighter at the lower end of DMG’s spectrum. In finally, not only the 22/40 hp was launched but also a larger and powerful model with shaft drive, the 28/50 hp. Its in-line engine developed 50 hp (37 kW) at rpm from a displacement of 7.2 liters. In output rose to 60 hp (44 kW) at 1300 and the designation correspondingly changed to hp.

The 28/50 hp (later 28/60 hp) was with either propeller or chain drive from 1912 until 1914. The applies to the 22/40 hp (later hp). Of this model, only a special version – a or colonial car – was offered for poor and rough terrain. The characteristic of the camper or colonial car was it higher clearance and larger track

Expansion of the range

One year the market launch of the 35 hp Mercedes propeller shaft drive, the hp model followed in May 1909, the range as an inexpensive entry-level with propeller shaft When displayed at the Paris Show in December 1908, the hp still had a conventional four-cylinder with upright valves. The version of 1909, by contrast, a more advanced design pendant intake valves.

The designation of the 15/20 hp model first figure indicating output, the second the actual was modified in 1909 analogous to the of the 35 hp model. The smaller car with shaft drive was now called the hp, with the first figure the tax horsepower calculated on the basis of From June 1913, the model was known as the 10/25 hp Its engine developed 25 hp (18 kW) at 1600

The 14/30 hp model was another car propeller shaft drive in terms of its design corresponded to the hp. It was launched in 1910 and had an engine 3.6-liter displacement. This developed 30 hp (22 kW) at 1600 rpm. In output rose to 35 hp (26 kW) at 1700 and the car was renamed 14/35 hp model.

Chain drive retained for automobiles

The 28/50 hp (28/60 hp) was a mid-sized model in the Mercedes lineup, with the other with propeller shaft ranging below it. In the upper segment, DMG continued to use chain In 1910 the 38/70 hp Mercedes – a car – was made available with drive only. It had a nine-liter with two pairs of cylinders, camshafts and upright valves. It was 38/80 hp model in June

The new Mercedes top model, the 37/90 hp in June 1911, equally had drive. This new high-performance car a four-cylinder engine with technology and dual ignition. It the six-cylinder models built 1907. A special innovation was the of encapsulated drive chains in an oil bath. Despite this chain drive was doomed to the 37/90 hp was the last newly car with chain drive Daimler-Motoren-Gesellschaft.

Eponym of “cardan

Daimler-Motoren-Gesellschaft consistently referred to cars”, named after the mathematician, philosopher and physician Cardano (1501 — Cardano was the first author of the modern period to describe the of measuring devices in a system of rings – a principle that had known since antiquity and was after Cardano at a later The universal joint, based on mechanical principles, was equally after Cardano even it was not invented by the Italian mathematician.

Chain drive was retained to the propeller shaft drive the debut of the so-called cardan One example was this chain-driven hp Mercedes of 1910.

Not just for cars: Propeller shaft was also a feature of this ambulance, model UK 2 of 1912.
