Description

Technical Field

[0001] The utility model relates to the technical field of automobile steering knuckle ball heads, in particular to a wear-resistant automobile steering knuckle ball head. Background Art

[0002] The steering knuckle, also known as the "ram's horn", is one of the important parts in the automobile steering axle. It can make the car run stably and sensitively transmit the driving direction. The function of the steering knuckle is to transmit and bear the front load of the car, support and drive the front wheels to rotate around the kingpin to turn the car. When the car is in driving state, it is subjected to variable impact loads, therefore, it is required to have very high strength.

[0003] The existing Chinese utility model patent with reference announcement number CN108869527B discloses a car steering knuckle ball head, including a main body, a threaded groove is provided on the top of the main body, a top dustproof net is threadedly connected to the inner wall of the threaded groove, the outer ring of the top dustproof net is fixedly connected to a track ring, a slide groove is provided at the bottom of the track ring, a track groove is provided at the outer bottom of the main body, a slider is slidably connected to the inner wall of the track groove, the end of the slider away from the track groove is fixedly connected to the sliding dustproof net through a threaded rod, and the top of the sliding dustproof net is slidably connected to the inner wall of the slide groove. The present invention relates to the field of steering knuckle technology. The car steering knuckle ball head can adjust the angle of the dustproof net according to the actual dustproof needs, so as to realize dustproof of the steering knuckle ball head without hindering the normal operation of the ball head, and at the same time, the air permeable groove increases the heat dissipation capacity of the ball head, which can effectively avoid the problem that the temperature of the ball head is too high after long-term operation, which easily leads to a shortened life.

[0004] Based on the search of the above-mentioned patents and combined with the equipment in the prior art, it was found that the steering knuckle is one of the main parts on the steering axle of a car. When the steering knuckle ball head is in use, the ball pin at the outer end will rub against the upper end shell when rotating, which will cause damage to the ball pin connection over a long period of time, and the ball head will wear when rotating, resulting in the need for subsequent replacement. When the steering knuckle ball head is in use, high temperature will be generated inside the steering knuckle ball head. The original steering knuckle ball head is a closed structure, which makes it impossible to dissipate heat inside, resulting in subsequent damage to the steering knuckle ball head. The existence of these problems affects the use of the device. Utility Model Content
