Three-line six-axis suspension fork for vehicle machines

Abstract

The invention discloses a three-line six-axis suspension fork for vehicle machines. The three-line six-axis suspension fork comprises mounting holes, wheel shaft brackets, steel plate springs and supporting frames, wherein the twelve mounting holes in all are formed in the supporting frames; a fixing shaft of each of the steel plate springs penetrates through one end of the corresponding steel plate spring to be embedded in the corresponding supporting frame, and penetrates through the other end of the corresponding steel plate spring to be embedded in a corresponding connecting axle; each of the wheel shaft brackets is fixedly connected with the corresponding steel plate spring; a wheel shaft assembly is connected with each wheel shaft bracket; a spring is mounted in each wheel shaft bracket; and each of the connecting axles is embedded in the corresponding supporting frame and is connected to the corresponding supporting frame through a corresponding connecting shaft. According to the three-line six-axis suspension fork for the vehicle machines disclosed by the invention, the middle two supporting frames adopt a triangular structure, and the triangular structures are stable and firm, so that the suspension fork can be more stable; and rotatable shafts are separately mounted at joints between each of the wheel shaft assemblies and the corresponding wheel shaft bracket, so that wheel shafts can swing from left to right, and a vehicle can be more smooth when travelling on an uneven road surface.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a three-wire six-axle suspension for vehicle machinery. Background technique [0002] A semi-trailer is a trailer whose axle is positioned behind the vehicle's center of gravity (when the vehicle is evenly loaded) and is fitted with a hitch that transmits horizontal and vertical forces to the tractor. [0003] For example, three-axle semi-trailers and three-wire six-axle semi-trailers are divided into 11-meter warehouse semi-trailers, 13-meter warehouse semi-trailers, and low-bed semi-trailers. It is a heavy-duty transport vehicle connected to the semi-trailer head through the traction pin. It is suitable for the transportation of bulk and scattered goods such as coal, ore, and building materials. [0004] At present, the domestic three-wire six-axle rigid suspension system is mainly used for large-tonnage and heavy-duty transportation. With the expansion of its application ra...
