The working principle and function of the tractor

Tractors are equipment used to transport large quantities of goods within or between workshops. They are widely used due to their strong specialization, large loading capacity, and fast transportation. A tractor is a large truck or semi-trailer that is towed with a tool between the front and the car, which means that the front of the car can actually be separated from the carriage. Let's take a look at the working principle and function of the tractor.

The working principle of the tractor 

The working principle of the tractor is as follows: there are one traction seat support on each of the 2 sides under the seat cover made of steel plate, which is connected with the seat cover by a pin, and the traction seat base is opposite to the seat cover. The plate can be rotated back and forth around the pin shaft. The bottom surface of the base of the traction seat is connected with the trailer to be pulled by bolts. There is a horseshoe, inclined iron, hook tongue, adjusting plate, cross bar, tie rod, spring under the seat cover. It consists of a locking mechanism, the horseshoe is fixed on the seat cover, the hook tongue, the pull rod and the cross bar are connected with a pin, the inclined iron is also connected with a pin, and the pull rod is connected to the rib under the seat cover by a spring. The utility model is characterized in that the two tails behind the saddle-shaped seat cover are large arcs, and the middle has a butterfly-shaped concave surface, which divides the entire plane into five parts of similar size.

Traction Control System, or TCS for short, is also known as ASR or TRC. Its role is to enable the car to obtain optimal traction in all driving conditions. 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 wheel and the non-driving wheel is too large, the computer immediately judges that the driving force is too large. , send out a command signal to reduce the fuel supply of the engine, reduce the driving force, and thus reduce 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 speed difference 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 is detected that the car is under-steered (or over-steered), the computer immediately judges that the driving force of the driving wheel is too large, and sends an instruction to reduce the driving force in order to realize the driver's steering intention.

The role of the tractor

1. Anti-skid: 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 traversing or drifting due to slippage of the drive wheels.

2. Flexibility: The car train has better maneuverability when pulling the car.

3. Reliable work: to ensure reliable, convenient and rapid disconnection between the tractor and the trailer.

4. Stable: The traction force can be smoothly transmitted to the trailer, which has a certain buffering effect on the impact load.
