Paul-daimler-wagen

Paul Daimler , the eldest son of the founder of Daimler-Motoren-Gesellschaft , has been working in the design office of his father since 1897. Due to the fact that he often had disagreements with Wilhelm Maybach , the chief designer of the enterprise, Daimler Jr. got his area of ​​competence, where he could work separately from Maybach. At this independent design office, Paul began developing his own compact car in 1899. In France, in particular, similar cars, known as “voiturettes”, were very popular at that time, and Daimler intended to gain access to this market segment with its own modern design ^[1] .

In June 1900, Paul Daimler's team interrupted their work in support of Wilhelm Maybach and his design bureau, encouraging them to finish work on the Mercedes 35 PS model. Due to lack of time, it was necessary to use all the power and resources of DMG to develop the first modern car. At the end of October 1900, Paul Daimler returned to his idea and completed the project, transferring the drawings to the workshop, which was supposed to begin the construction of three prototypes ^[1] .

For reasons that were not documented, the first vehicle was completed only a year later, in October 1901 ^[2] . It was equipped with a two-seater body with a direct steering column and an internal chain drive, which set in motion the internal gears of the rear wheels using a chain gear. Two months later, a second vehicle was ready for delivery ^[1] .

In April 1902, the third test car in a new version left the assembly shop. It was a four-seater with a tonneau body and a modernized design. This version had an inclined steering column and a conventional rear-wheel chain drive. All versions of the vehicles from Paul Daimler were equipped with a transverse two-cylinder in-line engine with automatic intake valves and exhaust valves located on the side. The working volume of the power unit was 1.4 liters, and the power was 8 hp. at 850 rpm ^[1] .

Despite the fairly modern design, the small car, which was known throughout the world as the “Paul Daimler car”, did not go into mass production - on the one hand, it would compete with the Mercedes brand models developed by Maybach, and on the other, the success of car sales Mercedes allowed DMG to reach full capacity ^[1] .

However, Paul Daimler, who in June 1902 became technical director of the Österreichische Daimler-Motoren-Commanditgesellschaft ( Austro-Daimler ), made a new attempt to sell his small car in Vienna. In March 1903, the “Paul Daimler lightweight car” was presented in a modified version in the back of a coupe and a double chaise at the International Automobile Exhibition in Vienna. Despite the fact that the automobile magazine “General Automobile Journal” gave a positive assessment of the cost of the new model, nevertheless, the car did not receive the expected success ^[1] .

Before World War II, two prototypes from Kanshtat - double and quadruple - belonged to the Daimler-Benz Museum collection. Due to military shocks and the loss of many items after the war, all traces of these two cars were lost, in connection with which it is assumed that not a single copy of Paul Daimler’s car was left ^[1] .

The car of Paul Damler was equipped with a four-stroke in-line two-cylinder ^[3] gasoline internal combustion engine with a working volume of 1410 cm ³ located in the front of the body. The engine design included 1 automatic intake valve and 1 adjustable exhaust (side, vertical). Valve control was provided with a single camshaft. The maximum power of the power unit was 8 horsepower ^[3] , which with a vehicle mass of 850 kg allowed it to reach speeds of up to 45 km / h ^[4] .

The chassis of the car was a steel frame with a U-shaped profile. The front and rear suspensions were a rigid axle with elliptical springs. Right-side steering was a worm-nut mechanism. The engine torque was transmitted using a chain, a four-speed manual gearbox with a clutch with peripheral coil springs and a gear to the rear wheels ^[5] .

The model was equipped with a mechanical brake system acting on the drive shaft. The parking brake was also mechanical and applied to the rear wheels.

The car was equipped with wheels with wooden spokes with steel rims (non-removable), on which carbide tires 870 × 90 in front and 1010 × 120 in back were fixed.
