The main structure of the steering knuckle assembly comprises a steering knuckle body 1, a composite bushing 2, a main pin shaft 3, a nozzle tip 4, a front shaft 5, a positioning pin 6 and a bearing 7. In the driving process of the automobile, the steering knuckle assembly bears larger and more variable impact load, and the requirement on the strength of the steering knuckle assembly is high. In daily maintenance, the steering knuckle assembly needs to be maintained regularly, lubricating grease is injected into the oil nozzle 4 of the main pin shaft 3, the lubricating function of the steering knuckle assembly is guaranteed, and if the daily maintenance is not available, the lubricating grease is not injected into the oil nozzle 4, so that the function of an automobile steering axle is reduced or the automobile steering axle is invalid. Meanwhile, the composite bushing 2, the knuckle body 1 and the main pin shaft 3 are matched with each other, so that the technical requirement on the knuckle body is high, and the processing difficulty is improved. The existing knuckle assembly is provided with an oil injection channel in the main pin shaft 3, and has the disadvantages of complex structure, high machining precision requirement, high difficulty in manufacturing and assembling and high manufacturing cost.
SUMMERY OF THE UTILITY MODEL

The purpose of the utility model is accomplished through following technical scheme: the utility model provides a self-lubricating knuckle assembly, mainly includes knuckle body, king pin axle, front axle, bearing, bush subassembly, emollient hole groove, and through bush subassembly installation king pin axle, the king pin axle of king pin axle connection front axle in the king pin hole of knuckle body, the bearing is installed to the pad between front axle lower surface and the knuckle body, and the surface of knuckle body and bush subassembly contact segment sets up a plurality of emollient hole grooves, packs solid lubricant in the emollient hole groove.
The inner diameter surface of the contact section of the steering knuckle body and the lining component is provided with a plurality of lubricant hole grooves A, and solid lubricant is filled in the lubricant hole grooves A.
The outer diameter surface of the contact section of the bushing assembly and the steering knuckle body is provided with a plurality of lubricant hole grooves B, and solid lubricant is filled in the lubricant hole grooves B.
The inner diameter surface of the contact section of the steering knuckle body and the lining assembly is provided with a plurality of lubricant hole grooves A, the outer diameter surface of the contact section of the lining assembly and the steering knuckle body is provided with a plurality of lubricant hole grooves B, solid lubricants are filled in the lubricant hole grooves A and the lubricant hole grooves B, and the positions, the sizes and the number of the lubricant hole grooves A and the lubricant hole grooves B are arranged correspondingly.
The utility model has the advantages that: the utility model has the advantages that the lubricant hole groove is designed and the solid lubricant is adopted, so that the lubricating grease has the self-lubricating function, does not need lubricating grease, and is free from maintenance; an oil injection passage is not required to be arranged in the pin shaft, a positioning pin is not required, the structure is simple, the assembly is convenient, the manufacturing difficulty is reduced, and the manufacturing cost is lower than that of a common steering knuckle assembly on the premise of the same performance; the problems that the steering knuckle assembly needs regular daily maintenance and lubricating grease injection, the structure is complex, the processing difficulty is high, and the cost is high are solved.

Description of reference numerals: the steering knuckle comprises a steering knuckle body 1, a composite bushing 2, a main pin shaft 3, a nozzle tip 4, a front shaft 5, a positioning pin 6, a bearing 7, a bushing assembly 8, a lubricant hole groove A9 and a lubricant hole groove B10.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
the utility model discloses a self-lubricating knuckle assembly mainly includes knuckle body 1, king pin axle 3, front axle 5, bearing 7, bush subassembly 8, emollient hole groove, and through 8 installation king pin axles 3 of bush subassembly in the king pin hole of knuckle body 1, king pin axle 3 connects front axle 5, fills up dress bearing 7 between 5 lower surfaces of front axle and the knuckle body 1, and knuckle body 1 sets up a plurality of emollient hole grooves with the surface of 8 contact segments of bush subassembly, packs solid lubricant in the emollient hole groove.
Example 1: as shown in FIG. 2, the inner diameter surface of the contact section of the steering knuckle body 1 and the bushing assembly 8 is provided with a plurality of lubricant hole grooves A9, and the lubricant hole grooves A9 are filled with solid lubricant.
Example 2: as shown in FIG. 3, the outer diameter surface of the contact section of the bushing assembly 8 and the knuckle body 1 is provided with a plurality of lubricant hole grooves B10, and the lubricant hole grooves B10 are filled with solid lubricant.
Example 3: as shown in fig. 4, a plurality of lubricant hole grooves a9 are formed on the inner diameter surface of the contact section of the steering knuckle body 1 and the bushing assembly 8, a plurality of lubricant hole grooves B10 are formed on the outer diameter surface of the contact section of the bushing assembly 8 and the steering knuckle body 1, solid lubricant is filled in the lubricant hole grooves a9 and the lubricant hole grooves B10, and the lubricant hole grooves a9 and the lubricant hole grooves B10 are arranged in a position, size and number corresponding to each other. The solid lubricant is used, and lubricating grease is not required to be injected into the steering knuckle assembly periodically, so that an oil filling hole is not required to be arranged in the main pin shaft 3, parts such as an oil nozzle 4 are not required to be used, and the manufacturing difficulty and the cost are lower than those of the original scheme. The number and size of the lubricant hole grooves A9 and the lubricant hole grooves B10 are determined according to specific working conditions and structures. When the steering knuckle body 1 and the main pin shaft 3 move, a thin lubricating film is quickly formed between friction surfaces generated between the steering knuckle body 1 and the bushing assembly 8 due to the filled solid lubricant, and due to low shearing strength, adhesion shearing is generated in the film during sliding, and intermetallic friction is changed into friction between the solid lubricants, so that the lubricating effect is achieved.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
