endurance than the horse power and more robust machines to make the wheels to turn faster.
Thousands of years later, in some parts of the United Kingdom and the United States, few people began to experiment with steam-powered, with a steel-made road. This steam train will be there, its use greatly reduces the distance people travel time. However, because of restrictions on the laying of tracks, most places only people to rely on the carriage. To solve this problem, to find a way to completely replace the carriage of goods, inventors began to busy again. Later, through unremitting efforts, Carl ? Benz developed a way to replace the carriage, is made of three cars of steel. Benz invented the three-wheeled vehicles loading only the equivalent of two carriages, the carriages are not comfortable shelter for passengers, can not get you recognized. Sooner or later gold will be shining, and soon was on the three vehicles has been transformed, it becomes four wheels, and has the same belt as the carriage window boxes, it also has a nice name, \
In this four-wheeled vehicles appears, with the biggest wagon is a different place when cornering. When the carriage is in turn control the horse drag to change the forward direction of the front two wheels, then connected with the two front wheels for steering the rear trunk drag movement. As the horse is a source of power, front wheel only to be dragged to complete turn of the horse, rear-wheel drive through the body

done, so there is no turning difficult problems. The car's structure is completely different, it will be the engine installed in the car body, but the forces driving the car forward, but must be sent directly to the wheels. Power transfer to go through the clutch, transmission, universal joints, drive shafts and other devices. This car's front and rear wheels out more between a lever, while the lever can only be passed back to a speed of two wheels, so a direct consequence of the rear wheels can rotate at different speeds, will result in turning difficult.
If the car turns smoothly, the two rear wheels can not turn the same speed. When the car turns, the wheel travel path is an arc, if turning left, the center of the arc on the left, at the same time, the right wheels to go a long arc than the left wheel. When the car turns left and right wheels to balance the difference the right wheels turn a little faster, turn the wheel left a little slower, with different speed to compensate for the distance differences.
Automotive engineers to solve this problem. First they try to make the two rear wheels are no longer using a lever connected but disconnected, so that the two rear wheels with a lever alone, that is, two independent axes, is the axle. As long as the lever on the axle of the two were subject to different forces, we can make about two wheels have different speeds. After the trouble came off, the car is only a drive shaft, how can two axle, respectively, to transmit power it reasonable? This

requires a device to do the middle of \two connections in the vertical angle of the lever connected to the rear, and then by a lever in a horizontal position and vertical position of the two levers intersect, so as to drive two rear wheels turn. Although such a connection can be made for the two rear wheels rotating, but can not achieve the two wheels rotate at different speeds, because their actual sense, or as a whole. After years of experiments found that the lever connecting the two rear wheels of the installation of a cross on the lever, and with them also installed a vertical angle of the same cross levers, and use this leverage to drive two wheels cross the cross on the lever. With the vertical angle of the cross lever rotation in the middle of the cross lever and not at the same time connecting the two rear wheels driven by the cross levers, wheels in order to achieve the two different speeds. Although this can solve the problem of two different speed rear wheel, but the space is too large cross levers, three cross drive lever prone to difficult situations. Then on the basis of the cross lever to add more leverage, increased to a total of twelve, to form a three twelve leverage wind wheel, so all three can be a good wind wheels turning. Solution model has manufactured, the total can not be directly installed in the car on it. With the wind in the mechanical function of the wheel is the same gear, and gear as needed to create more teeth to bite, life is relatively long, there is minimal chance of loss is completely the best choice to achieve

this model.
This design was simply to complete the original program does not actually applied to the car. Like any masterpiece needs a finishing touch to complete this amount of people is the founder of France, Louis Renault ? Renault. Renault saw the original design, in order to apply it to the car If we need to improve Caixing. Closely not only need to gear meshing, gear may also need to rotate together with the other gear, but gear can not be too much, six is enough. What is there, or should give it a nice name, \
In this way, to solve the problem of differential turning car was born. Over the next 100 years, other components for automotive appearance and generation after generation, but the key components is not much change, because it's composed of the principle that it is destined that way. Look like? Simple point that is formed by the six gears. Complex that is formed by a group of planetary gears, two core and two planetary gear shaft with the left rear wheel axle gear connected. What is a planetary gear? In the vast universe, there is such a planet, it is not only revolve around their own axis of rotation, but also around other planets to rotate. Such as the Earth, the Earth is a planet. Not only to rotation, but also around the sun to keep the revolution. Understand what is a planet, the planetary gear up it is easy to understand. Planetary gear means to turn that not only their own, but also around the other gears of the gear.

Differential is composed of six gears, planetary gear + two = four gear two axle gear, there are two. The remaining two gears with the drive rod is responsible for connecting the engine output power, gearbox and drive shaft after a smooth transition to the differential, then the differential will be based on the actual situation to the power distribution left and right rear wheels. Only differential installed in the rear axle drive rod between the two can achieve reasonable control wheel speed, in order to achieve the speed of two wheels with different purposes. In this six gear installed to the appropriate location, can not let them exposed it, still need a safe shelter to protect shell to protect the gear position is not affected by other parts of the interference. To save space, modern differential rarely use the classic flat gear, and more is to use the song bevel gears, screw gears, hypoid gears or worm, but the basic structure of the six gears have been continued down.
