Differential from the point of view of mechanics is considered as a device that distributes torque between the input shafts. It is located in the car drive. The differential of the car, respectively, distributes the moment from the input shaft of the gearbox or cardan between the axle shafts of the wheels of the car equally.
The differential is needed to make the drive wheels rotate at different angular speeds. When cornering, the inner wheel of a car travels a shorter arc than the outer wheel. And if the wheels rotate at the same speed, then one of them should enter the turn with slippage. This, in turn, will adversely affect the condition of the tires and handling. Also, the differential transmits torque to the drive axle continuously.
If the car has one drive axle, then the differential is located on it, if the car is with all-wheel drive, then there are three differentials on it - on the drive axles and between them. If the driving axle of the car is doubled, then a differential is located on each axle, as well as on cars with all-wheel drive. However, on such machinesWith all-wheel drive on, driving on dense surfaces is not recommended.
A limited-slip differential (or a limited-slip differential, abbreviated as DPVS) differs from the usual one in that the angular speeds of the input shafts are not equal. This is true when driving off-road. The limited slip differential allows you to continue driving in a situation where one wheel of the drive axle is not in contact with the road. Limiting the difference in the angular speeds of the wheels allows you to transfer a useful moment, while at least one of the wheels has contact with the road.
There are now two types of limited slip differentials used in today's automotive industry. The first type is a differential that is sensitive to the difference in moments (or torso). The second type is sensitive to the difference in speeds (created on the basis of a viscous coupling). This type is the most popular because it requires less maintenance.
The design of the viscous type differential is simpler compared to other types of limited slip differentials. A distinctive feature is that this type of operation is the most smooth.
Differential can be installed on various vehicles. Experts know, for example, the VAZ limited slip differential. There are also self-locking worm-type differentials. For example, the Quaife type limited slip differential (QUAIFE). It is designed for
cars with frontdrive. Such a differential will help to most fully realize the torque of the internal combustion engine on ice or if there is an excess of traction on the drive wheels. The wheel that has contact with the road receives additional torque, while unloading a wheel that has lost contact with the road or is slipping on ice. Passability of the car becomes better, acceleration in the winter season is the most dynamic. In addition, handling and accelerator pedal feel are improved.

"Thorsen" is one of the varieties of self-locking differentials. Such a mechanism is available both on domestic cars and on foreign cars. The principle of operation of the Torsen differential is based on the changing friction of mechanical parts, which leads to the distribution of torque between the wheelset

The self-locking differential provides an excellent opportunity to increase the ability of the car to overcome difficult driving conditions, while at the same time not requiring major structural changes to the design of the car, and is also affordable. The effectiveness of such devices is well known, it is not without reason that most army vehicles are equipped with them by default
