It seems to us that scientific and technological progress is moving forward, from the simple to the complex. Well, let's take a look at these unique inventions. Let's start with a truly fantastic machine. It should show at least because of its stunning appearance - it's like she's slipped into our world straight from the game, ruled by steampunk and dieselpunk. But it really was just like that-with steam and diesel power plants. Besides these units in the design of the machine was attended by seeming unreal in the beginning of the last century, the electric powertrain. The history of this device is as follows.
In 1889, the fire service of the city of new York received at its disposal a unique mechanism-a steam pump, but not ordinary, but truly gigantic. This was due to the fact that the city began to grow up, there were the first "skyscrapers" on the upper floors of which there were also fires. Manual pumps could not cope - the water pressure was required serious. Not helped by a low-powered steam pumps.
The new pump solved the problem of water delivery to the place of fire. But to deliver than the pump itself to the fire, given that it weighed nine tons? Eight heavy trucks, harnessed to a special cart with difficulty, but coped, but it was not always possible to turn around with such a team.
American engineers suggested a solution: use a steam engine pump as an engine. For a decent, at that time, the amount (seven thousand dollars) was designed a real "monster" - a self-propelled steam pump car. And he was good and went fast, saw the pump where you want, and only one "BUT" was this mechanism…
No matter how fast the steam car went, a lot of time passed before its "start": the steam engine required a certain pressure to start working, and the boiler was not heated instantly. It turns out that the saying “hurry like a fire” in this case was a black humor.
And here, in 1908 the new York steam pump receives "global upgrade" - for efficiency, in a design establish the gasoline internal combustion engine. And not just set, and in the "symbiosis" with the existing steam. Since the steam boiler is "integrated" into the rear wheel drive, it is difficult to redo it, and the petrol one uses it... front-wheel drive!
But that's not all: it was taken another fantastic innovation - electrotransmission. It solved the difficulties with the placement of the clutch and gearbox, to design and place that in the allocated space could not. The engine (which had six cylinders) was used to turn the generator, and it transmitted current to the electric motors of the drive of the front wheels.
It turned out to be a unique design, and if we take into account that the steam drive could also sometimes be included in the work, turning the steam-benzo-electric pump into a four-wheel drive unit, the machine was absolutely fantastic!
According to rumors, the car, having worked for many years, was written off and sold to a private collection of some lucky.
But the domestic development. However, implemented in England. Fantastic two-wheeled gyro count Shilovsky. Briefly, we have already shown it in one of our videos, but now we will add details about which few people know. In 1914, in London was shown a very entertaining car - it was designed for four people under the hood - gaining popularity petrol engine, but the wheels under the car was only two. They were located like a Bicycle, but the device did not fall even standing still and when moving at low speed!
Produced a remarkable mechanism Russian inventor, count Peter Petrovich Shilovsky. By the way, the former Governor of Kostroma. Special secret from his device Shilovsky did not: the balance of his car provided untwisted flywheel, creating the effect of a gyroscope.
With a total weight of about 2750 kg, the flywheel was made of metal with a thickness of 12 cm and a diameter of one meter. A pair of fifty-kilogram pendulums helped to avoid "distortions". A special electric motor powered by the main engine was spinning the pendulum.
It is interesting that initially Shilovsky offered his invention at home, but was extremely disappointed by the reaction of the authorities. Then he proposed the concept of his device car factory Wolsley motors in 1912, received consent and two years later showed the car to the public.
