Mercedes 35 hp

The Mercedes 35 hp was a sports car, the Daimler-Motoren -Gesellschaft developed after Emil Jellinek had ordered on April 2, 1900 a new type of car as the successor of Daimler Phoenix equal in dozens of copies. On December 22, the model was delivered to Jellinek.

Jellinek was an important man: The race- inspired car dealers and consul resided in Monaco and talked very best contacts in the glitterati of Europe on the Côte d' Azur. He drove Daimler cars in France, Italy and Switzerland. He demanded that the built according to his requirements and racing experiences in collective order car at the cooler the Spanish name " Mercedes " ("the Beneficent " ) contributed, by his idolatrous beloved daughter Mercédès Jellinek. She had delivered him the idea for his pseudonym with which he played his race: " Monsieur Mercedes".

Technical details of Mercedes 35 hp

Maybach first developed the new engine for him hovers in broad terms " Mercedes " cars. The horizontally split crankcase of the four-cylinder in-line engine was the first time Daimler made ​​of aluminum. For the main bearing Magnalium was used an aluminum alloy containing five per cent magnesium. The pair made ​​of gray cast iron cylinder heads were cast- in place of the removable of the " Phoenix" car. With a bore of 116 mm and a stroke of 140 mm resulted in a displacement of 5918 cc, 400 cc good more than the "Phoenix " cars.

The previously trained as sniffer valves intake valves - they open by negative pressure during suction - were now as the exhaust valves controlled by a camshaft. The drive of the camshafts unencapsulated left and right of the crankcase was through an open output gear on the flywheel side.

The exhaust camshaft drive over a arranged in their midst gear set the low-voltage magneto and a cooling efficiency -enhancing water pump, another set of wheels at the front end of the small fan behind the radiator. Per pair of cylinders, there was even that was new, one each carburetor. Controlling the speed between 300 and 1000 revolutions operated by a lever on the steering wheel.

All improvements provided in the end a lot more running, more stable idle and good acceleration performance - a new quality of engine characteristics, which was at that time held hardly possible. In addition, the engine weight reduced by 90 kg 230 kg.

The engine is no longer built Maybach with a sub-frame in the chassis a like until then common practice, but he narrowed the front frame part from pedal height such that the motor directly to the first time at the DMG made ​​of sheet steel pressed - bolted stringers - and not folded could be. Both measures he saved not only weight but also reached the desired lower center of gravity.

Entirely new design was the very small to be built and automatically nachregelnde wrap spring clutch, a coiled spring steel coil spring that was attached by a small drum on the shaft and mounted within the flywheel. Later developments of the car benefited from this design. A conical cam adjusted the spring tension when disengaging the clutch.

The four forward gears and the reverse gear were loaded with one out in a switching rocker arm. The gear was locked to the differential, the rear wheels are driven via drive shafts and open chains. The steering with a screw - steering gear was improved and further built behind and relatively highly inclined. The steering axles wandered far to the outside of the wheel hubs, which road impacts were mitigated lasting effect on the steering.

A compared to the "Phoenix " cars significantly longer wheelbase of 2245 millimeters and 1400 millimeters widened track led to a decidedly more stable ride of the new car. Also almost the same size wheels were on both axles used, but still in timber construction with twelve spokes. The two axles were rigid and suspended on semi-elliptic leaf springs.

The more powerful engine performance corresponded to the brakes. Mercedes was 30 centimeters drum brakes on the rear wheels, which are actuated by a hand lever and a linkage. The foot brake is acted on the driving shaft.

One of today unchanged in the ground substance inventions in this first "Mercedes" is the honeycomb radiator. Were usually made from coiled pipe cooler that caused a large-sized and heavy thus cooling circuit with a high water content. Maybach was a major step closer to solving the cooling problem in 1897 with the " tube cooler ". This consisted of many small tubes that were flushed from the cooling water and passed through by the wind. The larger air flow allowed a significant reduction in the water supply, but still comprised 18 liters. With the first time at the "Mercedes" realized honeycomb radiator Maybach achieved the decisive breakthrough. He left square, six by six millimeters measured tubes, there were 8070 pieces, a completely new, rectangular radiator solder together. The larger passage cross-section of the rectangular tubes and the smaller gaps between the tubes allowed a considerably increased cooling effect; the water demand dropped by half to nine liters. The improvement in cooling performance when driving slowly served the small fan behind the radiator. The honeycomb radiator was also used by other manufacturers until well after the First World War.

Successor to the Mercedes 35 hp was from 1902, the Mercedes Simplex.
