Extendable rigid draw bar’s compositions The extendable rigid draw bar device comprises two traction rods, the traction rod comprises a pipe body and a rod body, one end of the pipe body is provided with a connecting piece, the other end is sliding sleeved with the rod body.
The support device is divided into linkage support and single action support according to the operation mode. The former can make the linked left and right support devices rise and fall at the same time only by one person operating on one side of the vehicle.
When the special semi-trailer approaches the turning point, you need to send a left turn signal and reduce the speed within an appropriate distance in advance. Then you should shift into a low gear and drive close to the right side of the road, as well as turn on the left turn light at the same time. You should also observe the situation on the road. If the turning of the vehicles will not affect the vehicles on the road, you can quickly turn to the left and foot the steering wheel to make the vehicle slowly drive to the left of the road. When the front wheel approaches the roadside (about 1m away from the roadside), please quickly turn two to three directions to the right and stop.
At present, the semi-trailer produced in China adopts double pipe design. In the figure, ①blue line is the control pipeline, ②red line is the air supply pipeline, which is connected to the tractor through ③control air connector.
Always remember to control the steering wheel lock to rotate in the opposite direction to the reverse direction of the car, and observe the reversing mirror when reversing the trailer. A little more adjustment is appropriate.
Due to the large volume, semi-trailers are not suitable to move in a narrow space. However, they have to adjust the vehicle attitude in a narrow space under many working conditions. Thus, in order to solve this problem, the rear wheel steering system came into being.
The main components of semi-trailer hydrodynamic synchronous steering system include hydraulic pump, oil pipe, pressure fluid control valve, V-shaped transmission belt, oil storage tank and so on. This power assisted way is to convert part of the engine power output into hydraulic pump pressure to apply auxiliary force to the steering system, so as to turn the tires.
How to connect the tractor to the semi-trailer is a skill that every tractor driver must master. Especially for drivers engaged in drop and hitch transportation, they should pay more attention to all details in the connection process frequently, so as to ensure safe and efficient transportation.

For many friends who drive a semi-trailer, turning a small corner is often annoying. If you can't turn and need to get off again, it's much more troublesome than cycling. To solve this problem, WABCO has developed a technology called "optiturn" to help improve the steering flexibility of the vehicle
Many friends who operate semi trailers have this feeling. The problems of large tire wear, unavailability and short service cycle of the third axle of trailers virtually increase the operating cost. Therefore, some enterprises have developed a pneumatic steering axle for trailers.This pneumatic stee
