Abstract
The utility model discloses a conical roller bearing for supporting between an automobile hub and a steering knuckle. The conical roller bearing comprises an outer ring and an inner ring and is characterized in that axial length of the inner ring is longer than that of the outer ring, an annular boss is formed at the position of the end face of one end of the conical roller bearing, and an oil seal is arranged on the outer wall of the annular boss. The conical roller bearing for supporting between the automobile hub and the steering knuckle has the advantages of reducing parts quantity, simplifying installation procedure, and simultaneously lowering parts processing difficulty and production cost.
Description
Technical field
The utility model relates to a kind of bearing, relates in particular to a kind of tapered roller bearing for supporting between automotive hub and the knuckle.
Background technique
In the prior art, supporting structure between wheel hub and the knuckle is: the neck bush of knuckle is connected in the wheel hub, two positions of journal outer end and axle journal root respectively are provided with a bearing and are used to the rotation between wheel hub (see among the figure shown in the mark 5) and the knuckle (see among the figure shown in the mark 4) that supporting is provided, improvement of the present utility model namely is for that bearing that is arranged at the axle journal root (see among the figure shown in the mark 6), this bearing is tapered roller bearing, also be socketed with spacer ring (see among the figure shown in the mark 7) on the axle journal on tapered roller bearing right side, tapered roller bearing and knuckle are provided with the oil sealing of sealing usefulness with the spacer ring double team on the spacer ring outer wall; The problem that aforementioned structure exists is: because tapered roller bearing and spacer ring are two independently parts, adding man-hour, for fear of mutually interfering between the structure, must consider simultaneously the machining accuracy of the axial length of tapered roller bearing and spacer ring, improved the difficulty of making, simultaneously, because this position part is more, also quite bother when causing assembling.
The model utility content
For the problem in the background technique, the utility model proposes a kind of tapered roller bearing for supporting between automotive hub and the knuckle, comprise outer ring and inner ring, its improvement is: the axial length of inner ring is greater than the axial length of outer ring, thereby the end at tapered roller bearing one end forms an annular boss, is provided with oil sealing on the annular boss outer wall.After adopting aforementioned structure, be equivalent to original spacer ring and the inner ring on the tapered roller bearing are made as overall structure, bump (being annular boss) by inner ring supports for oil sealing provides tensioning, when making, only need consider the axial length of inner ring and the matching degree of mounting point, simplify preparation process, simultaneously, improve the degree of integration of structure, reduced cost of production; In addition, because the axial length of inner ring has obtained prolongation, so that the nominal load that tapered roller bearing can be born also is improved.
In order to improve the compatible degree between inner ring endoporus and the axle journal, the utility model has also been done following improvement: the endoporus of inner ring is the variable cross section hole, and this variable cross section hole is comprised of oared segrne pii and straight hole section, and the aperture of straight hole section is identical with the osculum end internal diameter of oared segrne pii; Oared segrne pii is arranged in the elevation scope of annular boss; The cross section of the inner hole wall at oared segrne pii place is the camber line of evagination.After adopting aforementioned improved, so that the endoporus port at oared segrne pii place without sharp parts, has been avoided damage axle journal root, improved the compatible degree between inner ring endoporus and the axle journal.
Useful technique effect of the present utility model is: reduced amount of parts, installation process is simplified, simultaneously, reduced difficulty of processing and the cost of production of part.

Embodiment
A kind of tapered roller bearing for supporting between automotive hub and the knuckle, comprise outer ring 1 and inner ring 2, its improvement is: the axial length of inner ring 2 is greater than the axial length of outer ring 1, thereby the end at tapered roller bearing one end forms an annular boss, is provided with oil sealing 3 on the annular boss outer wall.
Further: the endoporus of inner ring 2 is the variable cross section hole, and this variable cross section hole is comprised of oared segrne pii and straight hole section, and the aperture of straight hole section is identical with the osculum end internal diameter of oared segrne pii; Oared segrne pii is arranged in the elevation scope of annular boss; The cross section of the inner hole wall at oared segrne pii place is the camber line of evagination.
Claims (2)
1. one kind is used for the tapered roller bearing that supports between automotive hub and the knuckle, comprise outer ring (1) and inner ring (2), it is characterized in that: the axial length of inner ring (2) is greater than the axial length of outer ring (1), thereby the end at tapered roller bearing one end forms an annular boss, is provided with oil sealing (3) on the annular boss outer wall.
2. the tapered roller bearing for supporting between automotive hub and the knuckle according to claim 1, it is characterized in that: the endoporus of inner ring (2) is the variable cross section hole, this variable cross section hole is comprised of oared segrne pii and straight hole section, and the aperture of straight hole section is identical with the osculum end internal diameter of oared segrne pii; Oared segrne pii is arranged in the elevation scope of annular boss; The cross section of the inner hole wall at oared segrne pii place is the camber line of evagination.
