Tips to design gear motors

Modern cars are composed by thousands of parts, which are arranged in such a way that they meet the specific function of displacement of the vehicle, however a car is not only designed for this, for this reason, they are divided into many systems, among them are: the exhaust system, the support system, the engine, the steering system, the power system, the electrical system, cooling system, fuel system, brake system, among others, but you can’t forget about ac gears because they work really well.

Good motors guarantee good performance

The engine of a car needs to be compact and light weight, which generates a high power, easy to handle, rarely averíe and be quiet when operating. For these reasons, the petrol and diesel engines are used very often in automobiles. On the other hand, the main part of the car is the engine, where the power is generated to move the vehicle. A motor car includes equipment lubrication for each piece of cooling to prevent the overheating of fuel to feed it, intake and exhaust to make the air-fuel mixture, starting the engine, electricity generation systems for producing the necessary, elements of purification of exhaust gases to prevent air pollution, and other devices.

The engines develop their maximum power at a given number of revolutions. If the crankshaft was directly connected to the wheels, the result would be that you could only circulated efficiently at a given speed. To solve this problem, we use the change of gears, which is a system that modifies the relationships of speed and power between the engine and the drive wheels. In the european automobiles, the most widely used system is the gearbox of conventional, gear-scrollable. In the american cars are used much more systems Hydra-Matic and torque converters or torque.

The gearbox

A conventional gearbox provides four or five forward gears and a reverse gear or reverse. It is formed essentially by two shafts fitted with pinions fixed and scrollable of different sizes. The primary shaft, connected to the engine through the clutch, drives the intermediate shaft, one of whose sprockets fixed meshes with the pinion movable on the secondary corresponding to the selected gear (unless the lever is in the neutral position: in this case the secondary shaft is not connected with the intermediate). To the reverse is missing a pinion additional to change the direction of rotation of the secondary shaft. In the highest gear, the primary shaft is coupled directly to the side, rotating at the same speed. In the lower gears and in reverse gear, the secondary shaft rotates more slowly than the primary. When the secondary shaft rotates faster than the primary, there is talk of overdrive, which allows you to increase the speed of the car without the engine in excess of the normal number of revolutions.
