The Brief Introduction of Categories Transmission

Transmission is a common auto parts for a car. The main type for transmission can be classed into the following model. Namely, manual transmission (MT), automatic transmission (AT), automated mechanical transmission (AMT), double clutch transmission (DCT), Continuous Variable Transmission (CVT).The car’s transmission is related to whether the engine’s power can be outputted efficiently and favorably. It will affect the funny of driving, comfortable feelings and fuel consuming for driver and so on.

Transmission theory of gearbox:

1 MT is composed of the gears and shafts, producing the variable speed through the different gear combinations.

2 AT is composed of the hydraulic torque converter,

Automatic transmission is composed of hydraulic torque converter, planetary gear and hydraulic control system to achieve the variable speed torque through the combination of hydraulic transmission and gear.

The theory of shifting is also uncomplicated for us to understand. Please look at the following pictures, which can be understood easily via the pictures.

Readers can find that the speed or deceleration can be achieved by gear combinations of different teeth from the pictures writer showing. This is the theory of shifting of cars.

The basic functions of Gearbox

1 Change the transmission proportion, adapting to the different driving speed and driving conditions.

2 The car can be reversed by driver when the engine rotates in the same direction. This is the reason why most cars have the three forwards gears and a reverse.

3 Utilizing the neutral gear to break off the transmitting of the power, equally, keep the engine at idle speed status.

The aboved 3 statements, which makes gearbox receive the different Traction under the different speed to improve the transmission efficiency of the engine. In other words, customers can use the least fuel to drive far as possible as they could.

For example, Karting we played in park, which installs the Petrol Engine But it doesn’t have the gearbox. So there is only a forward one. This is the reason why Karting can drive so fast, even at 100 miles/hours. But, The high costs is that the fuel will be consumed by people quickly under the three thousands or four thousands turning run again and again.

So driver can keep the engine speed under from 2000 to 4000 turning circles through changeable  shift so that customers can saved the fuel consuming.
