Full trailer

Abstract

The invention provides a full trailer. The full trailer comprises a frame, a front wheel axle and a rear wheel axle, wherein the front wheel axle and the rear wheel axle are arranged on the frame; an L-shaped rigid steering traction rod is arranged at the position of a longitudinal central line of the frame at the front end of a front auxiliary frame in a rotating manner, and a horizontal transmission axle which is arranged between the front auxiliary frame and a rear auxiliary frame is located on the frame by supporting seats at the two ends in a rotating manner; a front swinging arm and a rear swinging arm are vertically fixed at the two end parts of the horizontal transmission axle, and are located in the same plane with the horizontal transmission axle; the upper ends of the front swinging arm and the rear swinging arm are respectively connected with the two ends of the horizontal transmission axle in a rigid manner, the lower ends of the front swinging arm and the rear swinging arm are respectively articulated with a front connecting rod and a rear connecting rod, and the other ends of the front connecting rod and the rear connecting rod are respectively connected with a rear steering arm of the front auxiliary frame and a steering arm of the rear auxiliary frame. When in corner turning, the full trailer can control rotating angles of the front / rear auxiliary frames and the wheel axles, so as to reliably and effectively control moving tracks of wheels of the full trailer, thereby reducing hidden dangers of the full trailer in running.

Description

technical field [0001] The invention relates to a full trailer which can effectively control the running track of its wheels. Background technique [0002] Trailers can be divided into full trailers and semi-trailers according to their own weight bearing methods, among which the trailers whose total weight is borne by themselves are full trailers. At present, all trailers are used independently, and there is no special steering control mechanism, so the walking trajectory of the wheels of the full trailer cannot be accurately controlled when walking. For some special full-trailers, such as a full-trailer train composed of multiple full-trailers connected in series, it is necessary to accurately and effectively control the walking trajectory of the wheels when the full-trailer turns or brakes. However, due to the long train length, the driver cannot Observing the running condition of the rear-end trailer, if the walking trajectory of each trailer wheel in the train cannot be...

AI Technical Summary

Problems solved by technology

At present, all trailers are used independently by a single unit, without a special steering control mechanism, so the trajectory of the wheels of the trailer cannot be accurately controlled when walking.

For some special trailers, such as a trailer train composed of multiple trailers connected in series, it is necessary to accurately and effectively control the trajectory of the wheels when the trailer is turning or braking. However, due to the long length of the train, the driver cannot Observing the running condition of the trailer at the rear end, if the wheels of each trailer in the train cannot be accurately and effectively controlled to walk on the same track, there will be a great safety hazard when the train turns or brakes, which will easily lead to accidents
