Abstract
The utility model relates to an automobile front axle hub which comprises a hub, a braking mechanism, a steering knuckle and a spring bracket. The braking mechanism is fixed at the outer side of the hub in a sheathing manner, the hub is provided with an axle hole and a wheel flange, an inner bearing hole and an outer bearing hole are axially arranged at the two ends of the axle hole, an inner bearing and an outer bearing are respectively arranged in the inner bearing hole and the outer bearing hole, the connecting ends of the steering knuckle are fixed in the inner bearing and the outer bearing, the tail end of the steering knuckle is connected with the spring bracket, and a ring-shaped lug boss which is raised towards the center is arranged on the side wall in the outer bearing hole. A stop washer, a hub axle head sleeve and a wheel axle nut are arranged at the outer side of the outer bearing hole. The inner side of the outer bearing is fixed towards a tabletop at the outer side by the ring-shaped lug boss of the outer bearing hole. The outer side of the outer bearing is fixed by the stop washer, the hub axle head sleeve and the wheel axle nut. With the above arrangement, the outer bearing can be more steadily fixed in the outer bearing hole of the hub, thereby improving the safety performance of an automobile.
Description
Technical field
The utility model relates to the auto parts and components field, is specifically related to a kind of automobile front axle assembly.
Background technology
Traditional automobile front axle assembly comprises: comprise wheel hub, stop mechanism, steering swivel and spring bracket, the sheathed wheel hub outside that is fixed on of stop mechanism, 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, be respectively arranged with neck bearing and outer bearing in neck bearing hole and the outer bearing hole, fixedly in neck bearing and the outer bearing, the steering swivel tail end is connected with spring bracket the steering swivel coupling end, the cylindrical structure setting of wheel hub axis hole.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 assembly of wheel hub axis hole internal fixation.
For reaching above-mentioned purpose, the disclosed automobile front axle assembly of the utility model, comprise wheel hub, stop mechanism, steering swivel and spring bracket, the sheathed wheel hub outside that is fixed on of stop mechanism, wheel hub 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, be respectively arranged with neck bearing and outer bearing in neck bearing hole and the outer bearing hole, the steering swivel coupling end is fixed in neck bearing and the outer bearing, the steering swivel tail end is connected with spring bracket, it is characterized in that: described outer bearing hole madial wall is provided with the annular boss to central protuberance, outer bearing hole arranged outside has stop washer, hub spindle headgear and axle nut, the outer bearing inboard is fixed by outer bearing orifice ring shape boss table top laterally, and stop washer is passed through in the outer bearing outside, hub spindle headgear and axle nut fix.So be provided with, when outer bearing is fixed on wheel hub outer bearing hole, because the annular boss platform wall laterally and the effect of stop washer, hub spindle headgear and axle nut, make outer bearing in wheel hub outer bearing hole, be difficult for producing displacement, 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, and the outside of neck bearing is fixed by neck bearing orifice ring shape boss table top to the inside.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 the ring-type concave station, and the hub spindle headgear is fixed in the ring-type concave station of axis hole outboard end.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 the ring-type concave station, and axis hole medial end ring-type concave station internal fixation is provided with 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 assembly technical 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
