Description

A kind of front hub bearing assembly of tour bus

Technical field

This utility model is related to tour bus accessory field, more particularly to a kind of tour bus, radio car, cruiser, transhipment The front hub bearing assembly of car etc..

Background technology

Front hub bearing assembly is mainly used to load-bearing and the rotation for hub bearing is carried as the important parts of automobile For accurate guide.However, before at present the manufacturer of domestic each size tour bus, radio car, cruiser, transfer car(buggy) etc. is used Hub bearing is following two structures：

First, filled that is, between two deep groove ball bearings 1 (with reference to shown in Fig. 1) by the way of two bearings combination With a positioning bushing 2, one end is positioned with knuckle boss or knuckle spindle boss, other end nut check.

2nd, using a double row angular contact bearing, a limiting retainer ring is added (to refer to shown in Fig. 2 at bearing assembling end ).One end is positioned with knuckle boss or knuckle spindle boss, other end nut check.

For standard component, low cost in theory, after-sale service is also convenient for the bearing that both modes are adopted.But actually make There is the perishable defect of bearing with during.Jing is analyzed, and in straight-line travelling, its hub bearing mainly receives radial force to vehicle； When Vehicular turn, hub bearing not only receives radial force, can also receive larger axial force.And the deep-groove ball that this kind of structure is adopted Though bearing can bear radial load, larger axial load can not be born.Another Jing investigations, the characteristics of this kind of wheel hub structure is perishable Caused after service cost exceeds well over the budget of each enterprise.Each car load manufacturer is seeking redress.

In addition, notification number for the U of CN 205639283 application documents in disclose a kind of hub bearing, it include outer ring, The ring flange being set in outer ring, the inner ring being set between outer ring and ring flange, are provided with middle washer between outer ring and inner ring, Outer ring is mortgaged inner ring on ring flange by middle washer, and this structure can effectively prevent inner ring from taking off in use Fall, be conducive to improving the performance of hub bearing.However, in actual use, if bearing adopts tapered roller bearing, by There is fit tolerance between component, thus control can be then more difficult to without very professional human users in the gap adjustment of bearing System, so has a strong impact on generation to the service life of bearing.

Utility model content

For above the deficiencies in the prior art, the utility model proposes one kind can bear radial force can also bear larger axle To power and assemble the front hub bearing assembly of simple tour bus.

To reach above-mentioned purpose, this utility model provides a kind of front hub bearing assembly of tour bus, including outer ring, is located at The ring flange of outer ring upper end surrounding and the inner ring being sheathed in the outer ring, the ring flange is connected with brake disc, institute State and be equipped between outer ring and inner ring rolling element, the outer ring is internally provided with and the boundary slip cooperation of the rolling element Outer ring recess, is provided with the inner ring recess coordinated with the boundary slip of the rolling element in the inner ring, the outer ring and described Ring flange is formed in one structure.

Further, the outer ring is provided with interior retainer with the inner of inner ring, and the outer ring is arranged with the outer end of inner ring There is outer retainer, sealing member is arranged on the outer retainer outside.

Further, the through hole corresponding with the screwed hole on the ring flange is offered on the brake disc, it is described to stop Linked together by bolt, spring washer between hull and the ring flange.

Further, the quantity of through hole is four on the brake disc.

Further, the outer ring and the ring flange are forging integrated formed structure.

Know-why of the present utility model is as follows：

By said structure, the beneficial effects of the utility model are as follows：

Outer ring of the present utility model and ring flange are integrally formed for forging, inner ring to dress because radial force can be born Large axial force can also be born；

In addition, the monolithic construction high precision of front hub bearing assembly of the present utility model, every hub assembly Bearing clearance can be accurately controlled within 0.008-0.02 scopes, and bearing is durable in use；

Further, because brearing bore is increased, front axle rigidity is greatly promoted, and more convenient assembling, when bearing life-time service When abrasion need to be changed, hub assembly is directly changed, it is simple to operation.
