Transmission is the most important element of each car, providing transmission, distribution and change of torque from the engine to the drive wheels. And if at least one gear in it fails, it will be impossible to continue driving on such a car. Today we will talk about the device of this mechanism, and also learn about the types of gearboxes.
Types of car transmissions
Today they are distinguished by two:
- Mechanical - invented over 100 years ago and used in most modern cars.
- Automatic - was developed much later than the first, but despite this, it is successfully used on many crossovers and hatchbacks. In turn, automatic transmission is a device that is divided into several subcategories. These are various tipronics, variators and so on.
The main difference between these devices is the method of gear shifting. And if in the firstIf the change in torque is provided by the motorist himself, switching the gearshift lever by pressing the clutch pedal, then in the second case, the entire process is controlled by electronics.
It should be noted that the gearbox can be divided into two more categories depending on the type of vehicle drive. Thus, if in a car the function of the driving wheels was assigned to the front ones, the transmission transmits torque directly to these axle shafts. If this is a rear-wheel drive car, here the cardan shaft is an intermediate link between the transmission of torque from the internal combustion engine to the wheels. Each of these cars has its own gearbox design. However, their function and purpose does not change.
Device
As we have already noted, the transmission is a mechanism that may have structural differences depending on whether the car is front-wheel drive or rear-wheel drive. However, the main devices in all modern transmissions are unchanged:
- Clutch.
- Differential.
- Halfshaft.
- Gearbox.
- Main and driveline.
So let's take a quick look at each of these mechanisms.
Clutch
The main function of this tool is to briefly disconnect the engine from the gearbox and then connect them when changing gears.
Gearbox (not transmission)
This is a mechanism that changes the torque of the transmissionmotor, thereby affecting the speed of the vehicle. By the way, at the VAZ Niva, the transmission is also equipped with a transfer case.
Gimbal drive
Used to transfer forces, that is, torque from the secondary shaft of the box to the main gear.
Differential
It serves to distribute the forces of the engine between the drive wheels. Thanks to the differential, the wheels of the car can rotate simultaneously at different angular speeds, which is necessary when the car enters a turn.
Each transmission has such a device. VAZ of the "tenth" family, "seven", "five", "Ural" and all other domestic cars have the same principle of operation and gearbox arrangement.

Steering wheel covers - beauty in every car
The steering wheel is one of the most visible elements in the interior of a car. It should look aesthetically pleasing so that the driver is pleased not only to look at it, but also to drive the car. The best way to achieve this is to buy steering wheel covers
The steering wheel of a motorcycle is an important technical element of a vehicle
All major controls (throttle handle, clutch and brake levers, turn and signal switches, rear-view mirrors) are mounted on the motorcycle handlebars. Not only the efficiency of performing various maneuvers when driving depends on this detail, but also in many respects the safety of both the motorcyclist himself and other road users
The steering column is an important element of the driving mechanism
Many motorists believe that the steering column is not a very complex and important part of the car, and do not pay enough attention to this element of the control system. And in vain
The automatic transmission device of a car and the principle of operation. Automatic transmission types
Recently, automatic transmissions are gaining more and more popularity. And there are reasons for that. Such a box is easier to operate and does not require constant “play” with the clutch in traffic jams. In large cities, such a checkpoint is far from uncommon. But the automatic transmission device is significantly different from classical mechanics. Many motorists are afraid to take cars with such a box. However, the fears are not justified. With proper operation, an automatic transmission will last no less than mechanics
Checkpoint is the most important part of a car
Checkpoint is the most complex technical mechanism designed to shift gears in a car. No car is able to continue moving without a gearbox. Today there are automatic and manual transmissions. The last one came out first. It is still used in many cars today
