And make motor turning.Under vehicle driving state, it subjects changeable shock loading, it is therefore desirable to which it is with very high strong
Degree.
Preceding bridge is to connect between knuckle and front axle by stub, realizes go to action to the rotation of knuckle, existing
Have front axle steering knuckle in technology includes knuckle ontology 100 and main pin 300, one on knuckle ontology 100 as shown in Figure 1:
Setting connection pedestal 200, the lower end of main pin 300 is closely interspersed in pedestal 200.Main pin 300 is interspersed in the prior art
The uniform diameter up and down at the position in pedestal 200 is consistent, and main pin 300 is easy to be abnormal abrasion in pedestal 200, makes automobile
In operational process, easily there is knuckle play phenomenon up and down in preceding bridge, and automobile front axle is caused to generate shake, influences car steering peace
Entirely.
Utility model content
The purpose of this utility model is in view of the above problems, providing a kind of automobile front axle slewing journal structure, structure is simple, easily
In processing, fitting tight can reduce the abrasion of main pin, improve the service life of knuckle.
In order to achieve the above object, the technical solution adopted in the utility model is: it includes the knuckle ontology being wholely set
And pedestal, main pin is closely interted in pedestal, pedestal is coaxially disposed the first circular hole, the first bellmouth, the second circular hole from top to bottom
With the second bellmouth；The lower end of main pin is stepped from top to bottom to be provided with the first cylindrical section, the first conical section, the second cylinder
Section, the second conical section and end；The first anti-wear gasket is successively arranged on first conical section, the second cylindrical section and the second conical section
Piece, the second anti-attrition gasket and third anti-attrition gasket；First anti-attrition gasket, the second anti-attrition gasket and third anti-attrition gasket match respectively
In the first bellmouth, the second circular hole and the second bellmouth.
Further, the first anti-attrition gasket and third anti-attrition gasket are taper.
Further, the second anti-attrition gasket is circle.
The utility model has the beneficial effects that the utility model provides a kind of automobile front axle slewing journal structure, structure is simple,
Easy to process, fitting tight can reduce the abrasion of main pin, improve the service life of knuckle.
The first anti-attrition gasket, the second anti-attrition gasket and third anti-attrition gasket are provided in the utility model in main pin,
It first anti-attrition gasket, the second anti-attrition gasket and third anti-attrition gasket and is matched respectively in the first bellmouth, the second circular hole and second
In bellmouth, it can be effectively prevent the abrasion of main pin, improve the service life of front axle steering knuckle.
