Abstract
The utility model relates to the field of automotive technology, a bearing unit supporting bridge is disclosed, including wheel hub, a bearing inner race, the 2nd bearing inner race, bearing inner race, be equipped with the spindle nose in the bearing inner race, the spindle nose is equipped with the spindle nose nut, a bearing inner race is equipped with first oil blanket, O type circle, the 2nd bearing inner race is equipped with the second oil blanket, bearing inner race is equipped with snap ring, sealing washer, the wheel hub lid is equipped with in hub end portion. The utility model relates to a novel the supporting bridge construction is to the weak point of conventionality supporting bridge and the long wheel hub unit supporting bridge of maintenance period is controlled easily to the life and the simple installation that can satisfy the wheel hub bearing that provide.
Description
Technical field
This utility model relates to automobile technical field, is specifically related to a kind of bearing unit supporting bridge.
Background technology
The installation of current domestic conventional supporting bridge hub bearing and use, two taper roll bearings are back-to-back to be arranged in hub spindle bearing bore, and after even twisting moment pretension axis head nut, rollback one fixing turn realizes the adjustment of bearing axial clearance.By the hub oil seal of side and wheel hub cover, two bearings is sealed in wheel hub, and hub inner lumen position grease up realizes the lubrication of bearing between two bearings.
The installation process of this conventional supporting bridge hub bearing is complicated, needs installation personnel accurately to control the axis head nut rollback number of turns, ensures appropriate bearing clearance, and bearing clearance is excessive or too small all will directly affect the service life of bearing.Wheel hub end housing side seal weak effect, and hub inner lumen is that non-machined surface easily the impurity pollution greases such as iron filings occurs thus affects the service life of bearing.This conventional wheel hub axle bearing structure needs periodically to check bearing, then needs to be carried out bearing as grease is contaminated, and changes whole grease, and the product maintenance cycle is short, and the long cost of maintenance time is high.
Summary of the invention
The deficiency existed for prior art, this utility model is a kind of novel supporting bridge structure, and the service life that can meet hub bearing and the simple installation that propose for the weak point of conventional supporting bridge are easily controlled, the hub supporting bridge of maintenance period length.
For solving above-mentioned technical problem, technical solution adopted in the utility model is: a kind of bearing unit supporting bridge, including wheel hub, clutch shaft bearing outer ring, the second bearing outer ring, bearing inner race, it is provided with spindle nose in described bearing inner race, described spindle nose is equipped with axis head nut, and described clutch shaft bearing outer ring is provided with the first oil sealing, O, and described second bearing outer ring is provided with the second oil sealing, described bearing inner race is provided with snap ring, sealing ring, and described hub end is equipped with wheel hub cover.
The advantage of this utility model bearing unit supporting bridge is: hub-bearing unit is used in supporting bridge, spindle nose, wheel hub, bearing, oil sealing, sealing ring form closed cell with snap ring, prevents dust foreign material from entering bearing；Improve supporting bridge bearing clearance adjust mode, by after the urgent axis head nut of even twisting moment without rollback, operate the easiest accurately.In the effective service life improving bearing, extend maintenance period.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is prior art construction schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
As shown in Figure 1, 2, a kind of bearing unit supporting bridge, including wheel hub 1, clutch shaft bearing outer ring the 2, second bearing outer ring 9, bearing inner race 5, it is provided with spindle nose 7 in described bearing inner race 5, described spindle nose 7 is equipped with axis head nut 11, and described clutch shaft bearing outer ring 2 is provided with the first oil sealing 3, O 4, and described second bearing outer ring 9 is provided with the second oil sealing 10, described bearing inner race 5 is provided with snap ring 6, sealing ring 8, and described wheel hub 1 end is equipped with wheel hub cover 12.
Bearing unit supporting bridge as shown in Figure 1, bearing unit (comprises bearing unit inner ring in being integrally attached to wheel hub, outer ring, oil sealing, intermediate seal circle, snap ring, O) constitute hub assembly, roller and inner ring smear grease, bearing roller gap should fill grease, then hub assembly integral press mounting is on spindle nose, 700-750Nm torque locking is used with axis head nut, suitable bearing clearance can be obtained and ensure the MaLS of bearing, without individually adjusting axis head nut, then assembly wheel hub cap, form closed cell, prevent dust foreign material from entering exposing of grease in bearing and bearing unit；Improve the utilization rate of grease, in the effective service life improving bearing, extend maintenance period.And after installing inside and outside bearing in conventional supporting bridge wheel hub shown in Fig. 2, turning round after needing axis head nut urgent and obtain bearing clearance, it is relatively big that the method obtains gap error, takes and often carries out checking adjustment, and when safeguarding, easily making dust impurity enter wheel hub cavity every time, infringement bearing reduces its service life.
Certainly, described above is not to restriction of the present utility model, and this utility model is also not limited to the example above; those skilled in the art; in essential scope of the present utility model, the change made, change, add or replace, all should belong to protection domain of the present utility model.
