6. What is the axle of a semi-trailer?
The automobile axle is connected with the frame through a suspension, and wheels are installed at both ends. The function of the axle is to bear the load of the vehicle and maintain the normal driving of the automobile on the road.
According to the different driving modes, the axles are also divided into four types: steering axle, drive axle, steering drive axle and support axle. Among them, the steering axle and the support axle are all driven axles.
The semi-trailers axle belong to the follow-up support axles, which do not have power. Semi-trailer axles include American axles and German axles. The capacity of Semi-trailer axles include 10T, 10.5T, 12T, 13T, 14T, 15T, 16T, 18T, 20T. We supply full range of semi-trailer axles to meet the different needs of customers.
The main parts of the axle include: main shaft, brake drum, brake shoe, brake lining, slack adjuster, S-camshaft, wheel hub, bearing, tire bolt, axle head cover, etc.
7. Features of Semi trailer axle:
1. Axle beam use 20Mn2 seamless pipe, through one-piece press forging and special heat-treatment, which has great over loading capacity and high intensity.
2. Axle spindle,which was processed by digital controlled lathe, is made of alloy material. The bearing position is processed by the method of hardending operation,therefore the bearing can be fixed by hand instead of heating, also convenient for maintain and fixing.
3. Axle spindle is connected by the by submerged arc welding, which make the whole beam more reliable and solid.
4. Axle bearing position is used the grinding machine to keep the bearing at the same level, after processing, it can assure that the concentricity within 0.02mm strictly.
5. Axle grease lubricant is supplied by EXXON Mobile which could providehigh lubricating performance and protect bearing well.
6. Axle brake lining is high performance, non-asbestos, non pollution and long service life. To make check and replace easily, also come with the position of the exhaustion to remind customer to check and maintain.
7. Axle bearing is adopted famous brand in China, with the advantages of over loading capability, High rotating speed, good intensity, abrade resistant and heat resistant.
In addition to supplying different types of Semi trailer alxe, HOTER GROUP also Supply different types of semi trailer components as below:
