Description
Technical field
The utility model relates to the field machine parts, is a kind of walker tractor traction component.
Background technology
Existing a kind of walker tractor traction component is vertically hinged by drawing head and connector front end, and connector rear end and draw beam are laterally hinged with composition.Drawing head and connector front end vertical hinged is to adopt in the axis hole of the upper and lower towing plate of drawing head axle sleeve is installed, the vertical shaft that connector is connected is loaded on the structure in the axle sleeve of the upper and lower towing plate of drawing head.Usually walker tractor is mainly in the loaning operation of travelling, because the road conditions condition is poor, the road surface is uneven, the vibrations of jolting of the walker tractor of the operation of travelling, make the stressed complexity of walker tractor traction component, even it is hinged that the drawing head of axle sleeve and vertical shaft that connector is connected have been installed,, also be difficult to resist and the effect of the complex external force of decaying because be to be rigidly connected, therefore, the vertical shaft that the axle sleeve of drawing head, drawing head and connector are connected damages easily, and service life is low, also fatal accident may occur.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of effect that can resist and decay complex external force is provided, walker tractor traction component safe in utilization, that the life-span is long.
The technical scheme that solves its technical matters employing is: a kind of walker tractor traction component, it comprises drawing head, connector, draw beam, its special character is: the structure of described connector is, the posterior end of girder is connected with horizontal cover, the front end of girder is fixed with main vertical cover and auxiliary vertical cover, in main vertical cover and auxiliary vertical cover, cover in the supporting is housed respectively, the girder front end be positioned at main vertical cover and auxiliaryly vertically put, the lower end is respectively equipped with upper and lower bearing, on the upper and lower bearing that is positioned at main vertical cover bearing is installed all; Upper and lower bearing is loaded in the built-in supporting of auxiliary vertical cover that the girder front end is connected in the cover by the aiding support axle, drawing head is loaded in the built-in supporting of the bearing of upper and lower bearing and main vertical cover in the cover by rotating spindle, and drawing head is connected with rotating spindle by bearing; Described draw beam structure is that supporting arm is connected with rotation transverse axis and circular beam; Draw beam is hinged by the horizontal cover that the rotation transverse axis that is connected and girder posterior end are connected.Cover is formed by overlapping in cover and the stage casing nylon in the upper and lower section rubber in the described supporting.
Walker tractor traction component of the present utility model compared with prior art since the girder front end be positioned at main vertical cover and auxiliaryly vertically put, the lower end is respectively equipped with upper and lower bearing, on the upper and lower bearing that is positioned at main vertical cover bearing is installed all; Upper and lower bearing is loaded in the built-in supporting of auxiliary vertical cover that the girder front end is connected in the cover by the aiding support axle, drawing head is loaded in the built-in supporting of the bearing of upper and lower bearing and main vertical cover in the cover by rotating spindle, drawing head is connected with rotating spindle by bearing, the structure that cover is made up of cover in cover and the stage casing nylon in the upper and lower section rubber in the supporting, increased the Joint strenght of drawing head and connector, cover all is the elastic support state to rotating spindle and aiding support axle in the supporting, the effect that can resist and decay complex external force, safe in utilization, the life-span is long.
