Abstract
The utility model discloses a heavy axle king pin structure, the swizzle body including syllogic step cylinder shape structure is the circular arc transition face between the ladder of the swizzle body. Utility model is circular arc transition face structure with the ladder transition design of original king pin, has eliminated stress concentration, improves back swizzle fracture fault and obviously reduces, when having satisfied whole car operation requirement, has improved product quality.
Description
Technical field
The utility model relates to vehicle bridge steering swivel field, specifically a kind of heavy axle steering yoke bolt structure.
Background technology
Steering swivel is one of main parts size on automotive axle, and automotive front load is born in the effect of steering swivel, supports and drives front-wheel rotate around stub and make motor turning.Under motoring condition, it subjects changeable impact load, therefore, requires that it has very high intensity.Existing steering yoke bolt is stepped cylindrical shape structure, and its ladder transition place is that wedge angle faces transition directly, stress can be caused to concentrate, cause the fracture of steering yoke bolt.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of heavy axle steering yoke bolt structure, solves existing steering yoke bolt stress and concentrates, the problem of easy fracture.
The technical solution of the utility model is:
A kind of heavy axle steering yoke bolt structure, including the stub body of syllogic stepped cylindrical shape structure, is arc-shaped transitional surface between the ladder of described stub body.
The arc radius of described arc-shaped transitional surface is 5mm.
Advantage of the present utility model:
The ladder transition of original steering yoke bolt is designed to arc-shaped transitional surface structure by the utility model, and eliminate stress and concentrate, after improving, stub fracture defect obviously reduces, and while meeting car load operating needs, improves product design.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
See Fig. 1, a kind of heavy axle steering yoke bolt structure, includes the stub body 1 of syllogic stepped cylindrical shape structure, is arc-shaped transitional surface 2 between the ladder of stub body, and the arc radius of arc-shaped transitional surface 2 is 5mm.
Claims (2)
1. a heavy axle steering yoke bolt structure, includes the stub body of syllogic stepped cylindrical shape structure, it is characterized in that: be arc-shaped transitional surface between the ladder of described stub body.
2. a kind of heavy axle steering yoke bolt structure according to claim 1, is characterized in that: the arc radius of described arc-shaped transitional surface is 5mm.
