Width-adjustable suspension mechanism of semitrailer

Abstract

The invention discloses a width-adjustable suspension mechanism of a semitrailer, and relates to the technical field of transport vehicles. The mechanism comprises a frame assembly, a plurality of inner sliding and overhanging beams which are symmetrically arranged are fixedly mounted on the two sides of the frame assembly, and wheel carrier assemblies are slidably arranged on the inner sliding and overhanging beams respectively; the wheel carrier assembly comprises outer sliding supports arranged on the inner sliding and overhanging beams in a sliding mode, the outer sliding supports are arranged on the inner sliding and overhanging beams in a sliding mode respectively, swing arm assemblies are installed on the outer sliding supports, the outer ends of the swing arm assemblies are connected with wheel assemblies, and expanding oil cylinders are hinged between the frame main vehicle and the wheel assemblies respectively. The expanding oil cylinders are used for driving the wheel carrier assemblies on the two sides of the frame assembly to move in the width direction of the frame assembly, and therefore width adjustment of the semitrailer is achieved. When the semitrailer suspension structure is used, the width and the wheel track of the semitrailer suspension structure can be adjusted, the semitrailer suspension structure can be matched with wind power tower barrels of various diameters, the problem that a large number of vehicles are occupied is effectively solved, and the use efficiency of the vehicles is improved.

Description

technical field [0001] The invention relates to the technical field of transport vehicles, in particular to a width-adjustable suspension mechanism for a semi-trailer. Background technique [0002] In recent years, with the rapid increase in global demand for clean energy, wind power has become one of the most important forms of power supply, accounting for an increasing proportion of total power generation. At present, domestic and foreign countries are vigorously continuing to build wind power projects, which has promoted the rapid development of the entire industry. [0003] With the continuous improvement of technology, the models and sizes of wind power generation equipment are becoming more and more diverse, and the diameter of conventional towers has covered the range of 2000-3800mm. At present, during transportation, semi-trailers of different widths need to be used to match towers of various diameters, which takes up a lot of vehicle resources and cannot meet the n...
