A customer asked, is it possible to see the tractor in daily life? In fact, it is possible. The tractor simply means that the front of the car and the box are towed by tools (that is, the front of the car can be separated from the original box and tow other boxes, and the box can also be separated from the original front of the car and be towed by other heads. ) General large trucks (semi-trailers) are tractors. The following is a specific introduction to what kind of tractor is a tractor, and the difference between a tractor and a trailer.
What kind of vehicle is a tractor? The front of the vehicle with driving capability is called a tractor, and the vehicle with no driving capability behind is called a trailer. The trailer is towed away by the tractor.
There are two ways to connect the tractor and the trailer: one is that the front half of the trailer is placed on the traction saddle above the rear section of the tractor, and the bridge behind the tractor bears part of the trailer's weight, which is a semi-trailer; The front end of the trailer is connected to the rear end of the tractor. The tractor only provides forward pulling force and drags the trailer, but does not bear the downward weight of the trailer. This is a full trailer.
The control device of the traction control system is a computer, which uses the computer to detect the speed of the four wheels and the steering angle of the steering wheel. When the car accelerates, if it detects that the speed difference between the driving wheels and the non-driving wheels is too large, the computer immediately judges that the driving force is too large. , Send a command signal to reduce the fuel supply of the engine, reduce the driving force, thereby reducing the slip rate of the driving wheel. The computer grasps the driver's steering intention through the steering wheel angle sensor, and then uses the left and right wheel speed sensors to detect the difference in speed between the left and right wheels; thereby judging whether the steering degree of the car is the same as the driver's steering intention.
If it detects that the car is understeer (or oversteer), the computer immediately judges that the driving force of the driving wheels is too large, and sends an instruction to reduce the driving force in order to realize the driver's steering intention.
It can be said that the tractor and the trailer coexist, why do you say that? Through the understanding of the above content, we know that the tractor is actually the forward of the tractor trailer! The traction control system can prevent the idling of the driving wheels when the vehicle is driving on wet and slippery roads such as snow, so that the vehicle can start and accelerate smoothly. Especially on snowy or muddy roads, the traction control system can ensure smooth acceleration performance and prevent the vehicle from sliding or flicking due to the slipping of the driving wheels.
