Abstract

The utility model relates to an automobile hub, relating to the technical field of automobile parts. The automobile hub comprises a hub body, and a first bearing hole, a hub inner cavity and a second bearing hole are axially arranged in the hub body. The first bearing hole and the second bearing hole are respectively positioned at the two sides of the hub inner cavity; the central axis of the first bearing hole, the hub inner cavity and the second bearing hole is consistent with the central axis of the hub body; and the side wall of the hub inner cavity is provided with a first reinforcing rib axially extending along the hub inner cavity. Compared with the traditional automobile hub, the automobile hub provided by the utility model has the advantages of high strength, good braking effect, long service life and the like, cannot be damaged easily and is suitable for generalization and use.

Description

Automotive hub

Technical field

The utility model relates to technical field of automobile parts, particularly a kind of automotive hub.

Background technology

Wheel hub is one of automobile brake part, belongs to the rotating part of car brake, and it mainly acts on is the major part that connects braking hub and semiaxis, and wheel hub is a housing, can make bearing roller correctly in place, makes each position connect proper fit mutually.In the design process of wheel hub; Should be specifically noted that the material and the strength character of wheel hub, at present, wheel hub adopts the spheroidal graphite iron casting usually; Spheroidal graphite iron is to obtain SG through nodularization and inoculated; Improved the mechanical characteristics of cast iron effectively, particularly improved plasticity and toughness, thereby obtained the intensity also higher than carbon steel.But find that in use hub bearing hole wall and inner chamber insufficient strength are high, be prone to disrepair phenomenon, directly influence braking effect and service life.

The utility model content

The utility model purpose is in order to overcome above-mentioned deficiency, to provide a kind of intensity high, the automotive hub of long service life.

For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of automotive hub; Comprise hub body; Be axially arranged with clutch shaft bearing hole, wheel hub inner chamber and second bearing hole in the said hub body; Said clutch shaft bearing hole and said second bearing hole lay respectively at the both sides of said wheel hub inner chamber, and the central axis of said clutch shaft bearing hole, wheel hub inner chamber and second bearing hole is consistent with the central axis of said hub body, and the sidewall of said wheel hub inner chamber is provided with along axially extended first reinforced rib of said wheel hub inner chamber.

As a kind of improvement, the lateral wall of said hub body is provided with along axially extended second reinforced rib of said hub body, and said second reinforced rib is positioned at the periphery in said clutch shaft bearing hole.Said second reinforced rib is provided with eight and be that center of circle annular array distributes with the central axis of said hub body.

As further improvement, said first reinforced rib is provided with four and be that center of circle annular array distributes with the central axis of said wheel hub inner chamber.

The beneficial effect of the utility model is: compare with existing automotive hub; Because the intracavity sidewall of the said automotive hub of the utility model is provided with first reinforced rib; So strengthened the intensity at wheel hub inner chamber place, reduced the generation that damages phenomenon, prolonged the service life of wheel hub.

Owing on the lateral wall of the hub body of clutch shaft bearing hole site, be provided with second reinforced rib, strengthened the intensity of hub bearing hole wall, reduced the generation that damages phenomenon, further prolonged the service life of wheel hub.

In sum, the said automotive hub of the utility model is compared with existing automotive hub has the intensity height, and not fragile, advantages such as good braking effect and long service life are suitable for promoting the use of.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment, further set forth the utility model.

Shown in Fig. 1, Fig. 2 and Fig. 3 are common; A kind of automotive hub; Comprise hub body 1; Be axially arranged with clutch shaft bearing hole 2, wheel hub inner chamber 4 and second bearing hole 3 in the said hub body 1, said clutch shaft bearing hole 2 and said second bearing hole 3 lay respectively at the both sides of said wheel hub inner chamber 4, and the central axis of said clutch shaft bearing hole 2, wheel hub inner chamber 4 and second bearing hole 3 is consistent with the central axis of said hub body 1; The sidewall of said wheel hub inner chamber 4 is provided with four first reinforced ribs 6, and is that center of circle annular array distributes with the central axis of said wheel hub inner chamber 4.Strengthen the intensity at wheel hub inner chamber 4 places, reduced the generation that damages phenomenon, prolonged the service life of wheel hub.

The lateral wall of said hub body 1 is provided with eight second reinforced ribs 5; Said second reinforced rib 5 residing positions are corresponding with the position in said clutch shaft bearing hole 2; Be positioned at the periphery in said clutch shaft bearing hole 2, and be that center of circle annular array distributes with the central axis of said hub body 1.Strengthen the intensity of hub bearing hole wall, reduced the generation that damages phenomenon, further prolonged the service life of wheel hub.

The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the utility model.
