Abstract
The utility model relates to an automobile front axle hub, which comprises a hub body, wherein a shaft hole and a wheel ring flange are arranged on the hub body; and an inner bearing hole and an outer inner bearing hole are formed at two axial ends of the shaft hole. The automobile front axle hub is characterized in that a ring-shaped lug boss protruded towards the center is arranged on the inside wall of the outer bearing hole. With the arrangement, when the outer bearing is fixed in the hub outer bearing hole, due to the outward lug boss wall action of the ring-shaped lug boss, the outer bearing in the hub outer bearing hole has low possibility of displacement, so as to further secure the outer bearing in the hub outer bearing hole and enhance the safety performance of automobiles.
Description
Technical field
The utility model relates to the auto parts and components field, is specifically related to a kind of automobile front axle wheel hub.
Background technology
Traditional automobile front axle wheel hub comprises: hub body, hub body is provided with axis hole and wheel flange, the axial two ends of axis hole are provided with neck bearing hole and outer bearing hole, the cylindrical structure of its axis hole, wheel hub be provided with in the following way with steering swivel: the neck bearing hole of wheel hub axis hole and outer bearing hole are located to be provided with neck bearing and outer bearing respectively, and the steering swivel coupling end is fixed in neck bearing and the outer bearing.Yet, the cylindrical structure of wheel hub axis hole, neck bearing and outer bearing are easy to generate displacement in car running process, make neck bearing and outer bearing at wheel hub axis hole internal fixation built on the sand, thereby influence the safety performance of automobile.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the utility model is proposed.The purpose of this utility model is to provide a kind of neck bearing and outer bearing at the more firm automobile front axle wheel hub of wheel hub axis hole internal fixation.
For reaching above-mentioned purpose, the disclosed automobile front axle wheel hub of the utility model, comprise hub body, hub body is provided with axis hole and wheel flange, the axial two ends of axis hole are provided with neck bearing hole and outer bearing hole, it is characterized in that: described outer bearing hole madial wall is provided with the annular boss to central protuberance.So be provided with, when outer bearing is fixed on wheel hub outer bearing hole, because the effect of annular boss platform wall laterally makes outer bearing be difficult for producing displacement in wheel hub outer bearing hole, and then make more firm being fixed in the wheel hub outer bearing hole of outer bearing, and then improved the safety performance of automobile.
The utility model further is provided with: described neck bearing hole lateral wall is provided with the annular boss to central protuberance.So be provided with, when neck bearing is fixed on the hub inner bearing hole, because the effect of annular boss platform wall to the inside makes neck bearing be difficult for producing displacement in the hub inner bearing hole, and then make and more firm being fixed in the hub inner bearing hole of neck bearing further improved the safety performance of automobile.
The utility model further is provided with: described axis hole outboard end is provided with for the fixing ring-type concave station of hub spindle headgear.So be provided with, make the hub spindle headgear, reduced because of the hub spindle headgear directly being fixed on getting loose of causing on the lateral surface of wheel hub wheel flange by being bolted in the ring-type concave station.
The utility model further is provided with again: described axis hole medial end is provided with for the fixing ring-type concave station of hub oil seal.So be provided with, make that the leakage of oil slit in the wheel hub axis hole is meander-like, thereby make that the hub oil seal effect is better.
In sum, the utility model automobile front axle hub technology scheme, tool neck bearing and outer bearing are in the more firm effect of wheel hub axis hole internal fixation, and the oil sealing effect is better.
Below in conjunction with Figure of description structure of the present utility model is further described:
Description of drawings
Fig. 1 is the utility model automobile front axle wheel hub structure figure
Fig. 2 is the utility model automobile front axle wheel hub and steering swivel johning knot composition
The specific embodiment
Referring to accompanying drawing 1, accompanying drawing 2, the disclosed automobile front axle hub technology of the utility model scheme, comprise hub body 1, hub body 1 is provided with can be for the axis hole 101 and the wheel flange 102 of steering swivel 2 installations, axis hole 101 axial two ends are provided with neck bearing hole 103 and outer bearing hole 104, and outer bearing hole 104 madial walls are provided with the annular boss 105 to central protuberance.So be provided with, when outer bearing 3 is fixed on wheel hub outer bearing hole 104, because the effect of annular boss 105 platform wall laterally, make outer bearing 3 in wheel hub outer bearing hole 104, be difficult for producing displacement, and then make outer bearing 3 more firm being fixed in the wheel hub outer bearing hole 104, and then improved the safety performance of automobile.
