What is differential lock in a car

In the case of moving the vehicle on a turn, each wheel rotates at slightly different speeds. This is due to the fact that the distance traveled by the outer wheels is slightly longer than the path of the inner ones. To do this, you need to have a differential device in the car.

Differential car principle of operation, destination

Purpose - adjusting the speed of the conductive wheels.

the cardan shaft rotates gears that transmit power to the penis to move the wheels. The trick is that the gear allows the semi -and, therefore, the wheel to rotate at different speeds.

The principle of operation

The torque is distributed by two outputs, each of which rotates at different speeds.

If one tire loses contact with the road, the opposite of it also feels a decrease in traction. In the worst case, the machine will stuck, and one wheel will spin free, and the other with the best clutch does not provide the required torque so that the car is moved from the place. Today's antipuncricing systems are reimbursed by the wheel with brakes.

The principle of operation is to release one car wheel and the transfer of the entire power of the "wheel of the least resistance". It is a logical method on solid, smooth surfaces. But when it comes to off -road driving, there are problems.

The powerful lock of the differential mechanism will help here. When it is switched on, whether the factory standard or after -sales refinement, it is "blocked" and begins to gradually control both wheels. This allows not only to continue the tire without the traction to spin in the hope of getting the road, but it also drives another, which has good contact with the surface.

What is differential lock in a car?

Action: Connection of the car wheel spin at the same speed. On sand, dirt and snow, the traction effort continues to flow to the tire with a higher clutch.

In an unbroken state, it behaves as an open differential device. Its lock on a surface with high contact, for example, on a dry asphalt, complicates the rotation of the car and can lead to a transmission explosion.

varieties of differential mechanisms

1. high friction. combines the concepts of open and blocked, most of the time works as an open, and then automatically begins to block when there is a whisper. Blocking can be achieved by viscous fluid, clutch or complex gear. Weak place: are reactive, not blocked until there is a swallow.
2. Working a car differential with electronic control. Electronic grip unit offers rheostat control between open and fully blocked regulations with adjustment, produced hundreds of times per second. For example, if a computer determines too high excess rotation when you turn, it can increase the lock to stabilize the car. Disadvantages: The traction effort is shifted towards a slower car.
3. With torque vector . Using additional gear for the axle of the axle, the device accurately regulates the traction effort, which is transmitted to each wire wheel. This creates a moment that slows or accelerates the rotation of the vehicle. Heavy, complex and expensive, and also lead to a slight decrease in fuel consumption.

Differential mechanism extends the life of the tires, minimizing their wear while turning.
