Many card friends who operate semi-trailer have this feeling. The problems such as large tire wear, unavailability and short service cycle of the third axle of trailer virtually increase the operation cost. Therefore, some enterprises have developed a special pneumatic steering axle for trailer.
This pneumatic steering axle uses air pressure to control the steering angle of the axle. When the trailer is driving in a corner, the centrifugal force exceeds a certain value, the pneumatic unit of the axle will control the axle to start steering, and the axle will return automatically when driving in a straight line.
At the same time, the bridge is also equipped with a locking device made of brake air chamber. When not in use, the bridge can be locked directly through the air circuit control unit.
Compared with the centrifugal follow-up steering axle, the steering mechanism of the pneumatic steering axle is more reliable. Even if it is used for a long time, the steering mechanism will not appear. The phenomenon of "swinging" of the axle caused by large wear and tear.
The steering structure of the centrifugal follow-up steering axle is relatively simple, and there is direct friction between the two working surfaces during operation. It is very easy to be worn and loose after long-term use. If the axle is not replaced, it will lead to the phenomenon of "swinging" of the axle.
Compared with the centrifugal follow-up steering trailer axle, the pneumatic trailer steering axle is obviously more advantageous and reliable in technology. Although the initial purchase cost will be higher, the tire replacement cost saved after long-term use will far exceed the cost of purchasing the steering trailer axle.
