Planetary gooseneck steering mechanism

TLDR: The planetary gooseneck steering mechanism has the advantages of being novel in design, simple and compact in structure and safe and convenient to use as mentioned in this paper, however, it is not suitable for heavy-cargo vehicles.

Abstract: The utility model belongs to the technical field of heavy-cargo transportation vehicles, particularly to a planetary gooseneck steering mechanism. The planetary gooseneck steering mechanism mainly comprises a traction pin, a sun gear which is connected with a traction pin seat, a slewing bearing internal ring with an internal gear ring, a slewing bearing external ring, a steering frame which is connected with a planetary gear and a steering driving oil cylinder; the height of the traction pin seat can be different; a certain transmission ratio is generated between the movement of the traction pin seat and the steering frame through a planetary gear train; the steering frame can be connected with the single-layer or double-layer driving oil cylinder; and the oil cylinder can be connected at two positions. The planetary gooseneck steering mechanism has the advantages of being novel in design, simple and compact in structure and safe and convenient to use.
