Description
Technical Field
The utility model relates to the technical field of mining vehicle axles, in particular to an axle knuckle thrust washer structure.
Background
The knuckle is one of the main parts on the steering axle of automobile, and has the functions of bearing the front load of automobile, supporting and driving the front wheel to rotate around the main pin to turn the automobile. The presently commonly used construction is a conventional thrust bearing construction, as shown in fig. 1.
The conventional thrust bearing structure is that a thrust bearing is installed in a groove of the knuckle 1; the problems are: 1) Because of limited space, the thrust bearing is generally a non-standard bearing and has high price; 2) When the thrust bearing is used for heavy-duty mining front axles, the design size of the thrust bearing is limited due to space limitation, and the fault rate of the thrust bearing is very high.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide an axle knuckle thrust washer structure.
The technical scheme provided by the utility model is as follows: the thrust washer structure of the axle knuckle is characterized by comprising a knuckle, a tin bronze washer, a steel washer and an O-shaped ring; the lower part of the steering knuckle is provided with a tin bronze gasket and a steel gasket from bottom to top in sequence, and an O-shaped ring is arranged between the steering knuckle and the steel gasket.
Further, the lower part of the steering knuckle is provided with a groove, and an O-shaped ring mounting groove is formed in the groove.
Further, an inner hole and an outer circle are arranged on the tin bronze gasket, a double-ring-shaped oil groove is arranged on one side end face, and the outer circle is in clearance fit with a groove at the lower part of the steering knuckle.
Further, an inner hole and an outer circle are arranged on the steel gasket, three straight-through oil grooves are formed in the end face of one side, and the outer circle is matched with a groove at the lower part of the steering knuckle; the straight-through type oil groove surface is attached to the end of the double-ring-shaped oil groove.
The utility model has the beneficial effects that: the thrust washer structure is used to replace traditional nonstandard thrust bearing structure and is used to bear the front load of automobile, support and drive the front wheel to rotate around the main pin to turn the automobile.

Detailed Description
For a better understanding and implementation, the present utility model is described in detail below with reference to the drawings.
As shown in fig. 2, 3, 4 and 5, an axle knuckle thrust washer structure is composed of a knuckle 1, a tin bronze washer 4, a steel washer 6 and an O-shaped ring 8; the lower part of the steering knuckle 1 is provided with a cylindrical groove 2, the groove 2 is provided with an O-shaped ring mounting groove 3, and the diameter of the groove 2 is matched with the excircle of a steel gasket 6; a tin bronze gasket 4 and a steel gasket 6 are sequentially arranged in the lower groove 2 of the knuckle 1 from bottom to top; the tin bronze gasket 4 is provided with an inner hole and an outer circle, the end face of one side is provided with a double-ring-shaped oil groove 5, and the outer circle is in clearance fit with the groove 2 at the lower part of the steering knuckle 1; the steel gasket 6 is provided with an inner hole and an outer circle, one side end surface is provided with three through type oil grooves 7, the outer circle is matched with the groove 2 at the lower part of the steering knuckle 1, and the double annular oil grooves 5 are in surface fit with the through type oil grooves 7; an O-ring 8,O type ring 8 is arranged between the knuckle 1 and the steel gasket 6 and is positioned in the O-ring mounting groove 3 of the knuckle 1.
According to the thrust washer structure of the axle steering knuckle, when the front axle steers, the steering knuckle rotates back and forth around the master pin, the tin bronze washer 4 and the steel washer 6 rotate relatively, the through type oil groove 7 and the double annular oil groove 5 are lubricated by lubricating grease, an oil film is formed on the joint surface of the tin bronze washer 4 and the steel washer 6, friction is reduced, and the O-shaped ring 8 effectively seals the lubricating grease between the tin bronze washer 4 and the steel washer 6.
The above description of the embodiments of the utility model has been given in connection with the accompanying drawings, but these descriptions should not be construed as limiting the scope of the utility model, which is defined by the appended claims, and any changes based on the claims are intended to be within the scope of the utility model.
