Imagination and inventiveness are the basis of the great progress of human beings and their societies. Thanks to them, the wheel was conceived and millennia later, the car. Even the sun today, are still developing many advances in the automotive industry to improve the performance and power of the cars, to increase the experience of driving a vehicle and also to ensure the safety of its passengers.
The well known Samsung, which has little to do with the automotive world, has just introduced a prototype system that aims to substantially improve road safety. In many media we have spoken of this new invention that deserves our applause: the “Safety Truck”.
The idea is brilliant and rather simple. In Argentina, as in Colombia and in other countries where motorways double and triple carriageway are only dreams they are the usual two-way roads where live motorcycles, cars, buses and trucks. Overshoot of the latter is a dangerous maneuver, as visibility is dramatically reduced by the colossal size of most trailers. If to this is added the huge amount of curves of our mountain roads, the result is a highly detrimental to road safety cocktail.
The company Samsung has a large fleet of trucks loaded with smartphones, televisions and high-tech appliances. At the front of some of these heavy cargo vehicles a wireless camera that transmits live what is happening in front of the truck was installed. The image is displayed in real time on the back of the trailer, on four giant screens liquid crystal, ie, flat and high definition. These monitors are specially designed for outdoor use, why the glitz and excess light should not prevent good visibility.
Car drivers moving behind large trucks can then be aware of what is happening in front of these large mobile structures and to calculate accurately and safely the ideal time to advance them. Thanks to this ingenious invention, not in vain is also known as “Transparent Truck”, drivers who are behind the trucks can provide emergency braking and obstacles on the road that would otherwise be invisible.
The prototype camera Samsung also has a night vision system that enables seamless operation of both day and night in this new technology.
Although the operation of prototype Samsung has been defended and approved by the South Korean multinational, the product has not yet been commercialized. It appears that transport companies have not yet managed to make profitable the installation of these monitors on trucks.
These rear displays should not be used for a different display than the images integrated in the front of the truck for obvious security reasons transmitted end camera. The idea of the device is not to create a distraction that can end up causing an accident, and transmit different information, such as commercial information, could be counterproductive – but economically interesting, but it is not.
The “Safety Truck” Samsung is an innovation that does not aim to change lives, but to save them.
Although you use it daily and many times per kilometer, maybe not you ever stopped to think how it acts in the whole car. So, this time, in our subsection basic mechanics, we tell you how the clutch of a manual car works.
When you start the engine, it has been idle about 1,000 RPM. But for the pair passes through the transmission to the drive wheels, something has to ‘connect’ block and transmission … but not permanently (because if not, the wheels all the time or the engine calaría as superior braking would move) . That element connecting both elements is the clutch.
These are the basic parts of a car clutch manual gearbox.
When you are in neutral, the engine turns ‘free’ and the vehicle is not moved by more than hasten (see how the gasoline engine works). So when you engranas the first and lift a little left foot, clutch gearbox coupled with the pinion and movement of the crankshaft is transmitted to the wheels. But of course, as the former is at once short and we must use the remaining relations (second, third, fourth, fifth …) as you need less power and more speed, between each clutch to disengage it is depressed, is ie to ‘disconnect’ the set on time and for a few moments to select different gears (click here to see how does a manual gearbox) before the clutch again (lift the pedal). So the left pedal have to step up relations both as to reduce.
Cars use a friction clutch that works by fluid (hydraulic) or what is more common, with a cable. A ‘pressure plate’ bolted to the flywheel exerts constant force by a diaphragm spring on the transmission plate. Many older vehicles have a number of regulatory springs back pressure plate, instead of a diaphragm spring.
The transmission plate (or friction) operates in a splined input shaft, through which power is transmitted to the gearbox. The plate has friction linings, similar to brake linings on both sides. This allows the transmission to run smoothly when the clutch is engaged.
Thus the clutch is operated from the left pedal.
When ‘deactuates’ the clutch (the pedal is released), one arm pushes another element against the center of the diaphragm spring, which releases the clamping pressure. The outer part of the pressure plate having a friction surface, and not subject to transmission plate with the flywheel, so that the power transmission is interrupted and another gear engageable.
In a hydraulic clutch, the pressure on the left pedal activates a master cylinder in a piston which transmits force through a conduit filled with liquid to a housing mounted clutch slave cylinder. The auxiliary cylinder piston is connected to the ‘release arm’ clutch.
The modern clutch has four main components: the cover plate (which incorporates a diaphragm spring), the pressure plate, the transmission plate and the collar.
The cover plate is bolted to the flywheel and the pressure plate puts pressure on the plate transmission through the diaphragm spring or in old cars, through regulatory springs.
The transmission plate works on an axis between the pressure plate and the flywheel. This is faced on each side, with a friction material that holds the pressure plate and the flywheel when fully engaged. It is slideable a controlled amount when the clutch pedal is released partially, allowing transmission work well. It is what is known as ‘half-clutch’.
The collar is pushed hard against the diaphragm spring, both hydraulically and by a cable and a lever, releasing the spring load to interrupt transmission of energy.

From there the car causes a traffic accident were always multiple. It can be a combination of alcohol, drugs and driving, inappropriate speed for road and traffic, poor condition of the vehicle, etc. However, until recently distracted driving was not taken into account when it would be one of the determining factors in increasing accidents factors.
In Europe, where mobile phone use is prohibited driving, it is too common to see people talking on the phone or typing a message on mobile. In other countries, the proportion of drivers responding to a driving WhatsApp or other message reaches alarming levels. Hence Volkswagen conduct a road safety announcement pioneer and disseminated in a Hong Kong film. No untangle the ad, you’ll see after the jump, but it is very well thought out. And as always in the most effective ads, part of a very simple idea.
I can now say. If you do not shut down or put the mobile in silent cinema, of course they will use driving …
