Sinotruk HOWO All Driving 6X6 Tractor Truck head is a general large truck or semi-trailer that is towed with tools between the front and the box, 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 box and pulled by other boxes. . The front of the vehicle with driving capability is called a tractor, and the vehicle with no driving capability behind it is called a trailer. The trailer is towed away by the tractor.
There are two ways to connect the tractor and the trailer: the first 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 the semi-trailer; One is that 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.
Brief introduction of Sinotruk HOWO All Driving 6X6 Tractor Truck head principle
Its working principle is: under the seat cover made of steel plate, there is a traction seat support on each side, which is connected with the seat cover by a pin, and the traction seat base can rotate back and forth with the pin shaft as the center relative to the seat cover. , The bottom surface of the traction seat base is connected with the pulled trailer with bolts. A locking mechanism composed of horseshoes, inclined irons, hooks, adjusting plates, cross bars, pull rods, and springs is arranged under the seat cover, and the horseshoes are fixed on the seat. On the cover plate, the hook tongue, the tie rod and the cross bar are connected by a pin shaft, the inclined iron is also connected by a pin shaft, and the tie rod is connected to the rib plate under the seat cover plate by a spring. It is characterized in that the two tails behind the saddle-shaped seat cover are large arcs, and there is a butterfly-shaped concave surface in the middle, which divides the entire plane into 5 parts of similar size.
Towing vehicle control system
Traction Control System, TCS for short, is also called ASR or TRC. Its function is to enable the car to obtain the best traction under various driving conditions. The control device of the traction control system is a computer that uses the computer to detect the speed of the four wheels and the steering angle of the steering wheel. When the car accelerates, if the difference between the speed of the driving wheel and the non-driving wheel 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 determining 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.
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.
