Problems solved by technology
The existing military tracked vehicle's crawler traveling mechanism has excellent shock absorption and obstacle-crossing performance, but the number of parts is huge, the composition structure is complex, and maintenance is difficult and cumbersome.
The structural complexity of the crawler mechanism of engineering tracked vehicles is much lower than that of military tracked vehicles, but its ability to absorb shock and overcome obstacles is poor.

The invention discloses a multi-swing-arm and multi-suspension type crawler walking mechanism. At least one swing arm suspension component is installed at one side of a frame. The swing arm suspension component comprises two swing arms, the upper ends of the two swing arms are fixedly connected through an upper end shaft, one end of an elastic damping connecting piece is rotationally installed an the upper end shaft, the other end of the elastic damping connecting piece is rotationally installed on a coupling shaft, the coupling shaft is fixed to a positioning shaft through a spring support, the positioning shaft is fixed to the frame, and the elastic damping connecting piece is obliquely arranged. The middle portions of the two swing arms are rotationally installed on an intermediate shaft, the intermediate shaft is fixed to the frame, and a plurality of belt supporting wheels used for making contact with the inner surface of a crawler belt rotating to the upper portion are rotationally installed on the intermediate shaft. The lower ends of the two swing arms are fixedly connected through a lower end shaft, and a loading wheel assembly used for making contact with the inner surface of the crawler belt rotating to the lower portion is rotationally installed on the lower end shaft. While good shock absorption and obstacle crossing performance is guaranteed, the structural complexity can be effectively reduced, and repair and maintenance are convenient.
Description
technical field [0001] The invention relates to a multi-swing arm and multi-suspension type crawler traveling mechanism for crawler vehicles, belonging to the technical field of crawler vehicle traveling mechanisms. Background technique [0002] According to whether it is military or not, tracked vehicles can be divided into military tracked vehicles and engineering (civilian) tracked vehicles. The existing military tracked vehicle's crawler running mechanism has superior shock absorption and obstacle-crossing performance, but has a huge number of components, complex structure, and difficult and cumbersome maintenance. The structural complexity of the crawler mechanism of engineering tracked vehicles is much lower than that of military tracked vehicles, but its ability to absorb shock and overcome obstacles is poor. It can be seen that the crawler running mechanisms of existing military tracked vehicles and engineering tracked vehicles have some deficiencies respectively. H...
