Description
Technical Field
The utility model belongs to the technical field of the auto steering axle, concretely relates to turn to axle king pin end cover structure is applied to the front axle assembly.
Background
In the domestic automobile steering axle, the lower end cover of the main pin is connected with the main pin by adopting a hollow bolt structure, and the outer diameter of the end cover is matched with the steering knuckle by adopting a rubber structure for sealing. This structure has the following disadvantages: threaded holes need to be machined in the main pins, so that the machining cost is increased; the end cover is made of a steel plate and rubber composite material, so that the cost is increased, and the rubber rotates relative to the steering knuckle, so that the sealing failure risk is increased; the processing technology of the hollow bolt is complex and the cost is high.
Disclosure of Invention
The utility model discloses a solve current auto steering axle, owing to adopt the hollow bolt structure to be connected to the swizzle with the bottom end cover, lead to swizzle processing cost, end cover cost increase, the seal reliability of end cover descends and the cost increase scheduling problem of hollow bolt, provides a steering axle swizzle end cover structure, and reduce cost promotes the reliability.
The utility model aims at realizing through the following technical scheme:
a kingpin end cover structure of a steering axle comprises a kingpin 1, a steering knuckle 2, an end cover 3, an O-shaped ring 4, a hexagon nut 5, a gasket 6 and a grease nozzle 7.
The shaft diameter of the kingpin 1 is arranged in a round hole of the steering knuckle 2, and the shaft and the round hole can rotate relatively; the circular hole of the O-shaped ring 4 is sleeved in an annular groove on the shaft diameter of the steering knuckle 2; the diameter of the thread of the grease nozzle 7 penetrates through the round hole of the end cover 3, the diameter of the thread of the grease nozzle 7 penetrates through the round hole of the gasket 6, and the diameter of the thread of the grease nozzle 7 is connected with and screwed with the threaded hole of the hexagon nut 5; the inner hole of the ring of the end cover 3 presses the shaft diameter of the steering knuckle 2 and is attached to the outer diameter of the O-shaped ring 4.
Furthermore, the end cover 3 is stamped into a bowl-shaped structure by adopting a steel plate, and the bottom surface of the bowl-shaped structure is in a round hole structure and is matched with the grease nozzle 7; the circular hole structure of the annular surface is adopted and is connected with the steering knuckle 2; the outer edge of the bowl shape adopts an outward flanging structure as a leading-in structure when being assembled with a steering knuckle.
Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model discloses turn to axle king pin end cover structure. The kingpin lower extreme end cover adopts bowl type stamping structure, and adopts shaft hole interference press fit between the knuckle, for original structure, adopts hollow bolt to be connected to the kingpin with the end cover promptly on, possesses following advantage: the processing cost of the main pin is reduced; the manufacturing cost of the end cover is reduced; the sealing reliability is improved; the processing cost of the hollow bolt is reduced.
Drawings
The invention will be further described with reference to the accompanying drawings:
