Abstract
The utility model relates to a track pin structure. This track pin structure changes traditional thick wall steel hollow pipe into thin wall steel tube, and the aluminum alloy core stick is placed to inside, not only is superior to steel hollow pipe in the stiffness, and weight reduction is greater than 20% moreover. The utility model is not only simple in structure, consequently easy to carry out, facilitate promotion have wide prospect.
Description
Technical field
This utility model relates to a kind of track pin structure。
Background technology
The track pin used of crawler-type special vehicle known today is heavy wall steel hollow pipe or solid steel bar is made, usual crawler belt weight accounts for complete vehicle weight and reaches more than 20%, crawler belt is to be in series by track section, required joint number is more, therefore, the weight often saving track section is reduced whole pair of crawler belt is significant。
Summary of the invention
For the track pin structure of conventional track special vehicle, the present invention provides a kind of track pin structure that can significantly alleviate weight。
This track pin structure includes thin-wall steel tube 1, aluminium alloy plug 2, and it is internal that described aluminium alloy plug 2 is positioned over thin-wall steel tube 1, to improve the stiffness of thin-wall steel tube 1。
Traditional heavy wall steel hollow pipe is changed into thin-wall steel tube 1, internal placing aluminium alloy plug 2 by this track pin structure, is not only better than steel hollow pipe in stiffness, and alleviates weight more than 20%。
The present invention is not only simple in structure, easy to implement, be easy to promote, therefore have wide prospect。
Accompanying drawing explanation
Fig. 1 is track pin structural representation。
Detailed description of the invention
Traditional heavy wall steel hollow pipe is changed into thin-wall steel tube, internal placing aluminium alloy plug by this track pin structure, is not only better than common heavy wall steel hollow pipe in stiffness, and alleviates weight more than 20%。
