The transmission of the car is intended fortransmission of torque from the engine to the driving wheels of the machine. In this case, the value of the torque changes. In the front-wheel drive car, the front wheels are leading, the torque is applied to them, in the rear-wheel drive - to the rear wheels. Machines in which torque uses all four wheels, four-wheel drive.
The transmission of the car is technically quiteMultifunctional mechanism, which, in turn, involves smaller connections. It includes: clutch, gearbox, various hinges, differential, propeller shaft (which is used only in rear-wheel drive vehicles, to connect the rear wheels with the engine). And "grenades" - equal angular joints, they are used only in front-wheel drive vehicles.
Transmission functions:
- for transferring the torque from the engine to the driving wheels;
- changes the direction of the torque and its magnitude;
- distribution between the wheels of torque.
The transmission of a car in our time must havehigh reliability with minimum costs for production. Therefore, the requirements for its quality are quite high. According to the transformation of energy, the transmissions are divided into the following types:
- electrical, carries the transition of mechanical energy into electric energy, advanced it to the driving wheels, again goes from electric to mechanical;
- combined, there is electrical and hydromechanical energy;
- hydro-volumetric, with the help of mechanical energy creates a flow of liquid, entering the driving wheels, then goes back to the mechanical one.
More is used in cars mechanical transmission.
Transmission, automatically changing the torque, was called "automatic transmission".
When using only the front - front-wheel drive car.
When using the rear - rear-wheel drive.
The structure of the transmission itself is different and depends on the driving wheels.
So understand and understand what a transmission is, before making your choice.
The behind-wheel drive machine has such units:
- Transmission;
- clutch;
- main gear;
- gimbal transmission;
- semiaxis;
- differential.
The composition of the front-wheel drive machine includes:
- Transmission;
- clutch;
- transfer home;
- differential;
- drive shafts "semi-axles";
- hinges.
In the front-wheel-drive car, the gearbox has a differential with final drive.
Hinges (pivotal connection of parts) transmittorque on the wheels with differential, which are leading. When connecting to the differential, two more hinges are used. They complete the transition of torque to the wheels.
Automatic transmission of the car onToday is more expensive in production, so much attention is paid to its development and improvement. This is the trend of today's world. It is more secure. In city traffic, the driver is less tired.
