Its working principle is: there is a traction seat support on both sides below the seat cover plate made of steel plates, which is connected to the seat cover plate with a pin shaft. The traction seat base can rotate back and forth with the pin shaft as the center. The bottom surface of the traction seat base is connected to the towed trailer with bolts. A locking mechanism consisting of a horseshoe, an inclined iron, a knuckle, an adjusting plate, a cross bar, a pull rod and a spring is set below the seat cover plate, and the horseshoe is fixed on the seat cover plate, A pin shaft is used to connect the knuckle, pull rod and cross bar. The inclined iron is also connected with a pin shaft. The pull rod is connected to the rib plate under the seat cover plate by a spring. The utility model is characterized in that the two tails behind the saddle shaped seat cover plate are large arcs, and the middle part has a butterfly shaped concave surface, which divides the whole plane into five parts of similar size.
Traction Control System (TCS for short), also known as ASR or TRC. Its function is to enable the vehicle to obtain the best traction under various driving conditions. The control device of the traction control system is a computer. The computer detects the speed of 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, and sends 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; So as to judge whether the steering degree is the same as the driver's steering intention. If the vehicle understeer (or oversteer) is detected, the computer will immediately judge that the driving force of the driving wheel is too large, and issue a command to reduce the driving force, so as to achieve the driver's steering intention.
The traction control system can prevent the idling of the driving wheels when the vehicle is running on wet roads such as snow, so that the vehicle can start and accelerate smoothly. Especially on snow or muddy roads, the traction control system can ensure smooth acceleration performance and prevent the vehicle from sliding or flapping due to the slipping of driving wheels.
Main classification
In the market, tractors are mainly divided into full trailer tractors and semi trailer tractors
1. Semi trailer tractor: 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 weight of the trailer.
2. Full trailer tractor: the front end of the trailer is connected to the rear end of the tractor, and the tractor only provides forward pull to drag the trailer, but does not bear the downward weight of the trailer.
Function of tractor
1. Anti slip: prevent the driving wheel from idling when driving on wet roads such as snow, so that the vehicle can start and accelerate smoothly. Especially on snow or muddy roads, the traction control system can ensure smooth acceleration performance and prevent the vehicle from sliding or flapping due to the slipping of driving wheels.
2. Flexibility: It enables the vehicle train to have better mobility and flexibility when towing the vehicle.
3. Reliable operation: ensure reliable, convenient and rapid decoupling of the tractor and trailer.
4. Stability: the traction force can be transmitted to the trailer smoothly, and has a certain buffer effect on the impact load.
