What is the automobile turntable? What is the trailer turntable? What is the casting turntable?

In order to improve the transportation efficiency of vehicles (Trucks, Trailers, tractors), Pull and Drag transportation, especially full trailer transportation, has been widely used. The casting trailer turntable is an important assembly part of the full trailer, which plays the role of steering, bearing and the connection between the main frame and the sub-frame. The trailer turntable is suitable for automobiles and tractors, and belongs to the steering mechanism of trailers.

Turntable in using for trailers:

During the driving of a full trailer, the turntable has to bear static and dynamic loads in three directions: vertical, longitudinal and horizontal. Therefore, its carrying capacity and working reliability will directly affect the driving safety of the full trailer. The quality of its structure, service life and ease of maintenance will also affect the manufacturing and use cost of the trailer and the reputation of the product.

Most of the trailer turntables are of single raceway structure. That is, the upper and lower flanges are matched with cylindrical surfaces, and the two flanges are connected by a single ball. At the same time, due to the lifting requirements of the load, the double-track trailer carousel turntable is also welcomed by many customers. The turntable should rotate freely without blocking. When the turntable is not under load, the circumferential tangential force acting on the turntable should not exceed 80N.

The characteristic of the trailer turntable is that there are raceways on the radial and axial contact surfaces of the upper and lower turntables, and balls are placed in the raceways. A screw hole communicating with the axial raceway on the other side is opened on one side of the turntable. The fixed position between the upper and lower turntables of the trailer turntable is stable, and each ball is only subjected to a single axial or radial force, so that the service life of the entire turntable can be prolonged, and the rotation is more flexible. It is suitable for various automobiles, Tractor trailers and agricultural trailers.
