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.

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.
