Abstract
A mounting and sealing structure of a steering column bearing comprises a mandrel, a column tube, a bearing, a boss and riveting column points, wherein the bearing is arranged between the mandrel and the column tube, the boss for limiting the bearing and the riveting column points are arranged on the column tube, a sealing stop ring for sealing is arranged below the bearing and matches with the riveting column points, at least four riveting column points are uniformly arranged on the column tube circumferentially to enable the bearing to be stressed uniformly, and the sealing stop ring is in interference fit with the mandrel and the column tube so as to improve leakproofness. The mounting and sealing structure can solve the problem that the stress to the steering column bearing is strong and non-uniform and can effectively overcome the defects of overlarge steering torque, abnormal steering sound and the like caused by improper control to riveting force of the column tube. The sealing stop ring can greatly seal the bearing and is waterproof and dustproof, so that the service life of the steering column is prolonged. The mounting and sealing structure can be widely applied to the field of steering columns of cars.
Description
Technical field
The utility model relates to a kind of sealing configuration of steering column, relates in particular to a kind of installation sealing structure of steering column bearing.
Background technique
Steering column is as the operation equipment of automobile steering system, and connecting direction dish and commutator are distinguished in its upper and lower two ends, and the quality of its performance directly has influence on driver's operation comfort.Rubber needle bearing is generally selected in steering column lower end at present, to reduce the requirement to tubing string mandrel and column jecket coaxality, the mounting type of lower end rubber bush bearing generally adopts and column jecket interference fit, it is spacing that rubber needle bearing top and column jecket boss or hole coordinate with back-up ring, and bottom is directly fixed by 4 rivetings of column jecket.This kind of mode is simple in structure, but column jecket processing and riveting power are had relatively high expectations, as inhomogeneous in the power that presses, easily cause the faults such as steering torque is excessive, rotation abnormal sound, secondly, rubber needle bearing is not considered to prevent dust, the needs of waterproof, for rubber needle bearing is arranged in the steering column outside operator cabin, will badly influence usability and the working life of steering column.
As number of patent application 200520114619.1 discloses a kind of steering column bearing mounting and positioning device, be arranged on steering drive axle and be arranged in steering column, comprise: bearing, nonmetal cover, precision positioning circle and axle sleeve, described nonmetal cover surface is along circumferentially slotting and being fixed on described bearing, described precision positioning circle outer surface is provided with multiple projections and is arranged in the fluting of described nonmetal cover, the external diameter of described precision positioning circle is greater than described nonmetal cover external diameter, described bearing is fixed on axle sleeve, and described axle sleeve is fixedly mounted on described steering drive axle.Adopt this device can relax tradition and be press-fitted tolerance and reduce assembly force, to adjust the resonant frequency of whole device, allow axle slight inclination and misalign, to can reduce noise, thermal diffusivity is good.Bearing unsealing, easily intakes into dust, affects the working life of steering column.
Model utility content
The purpose of this utility model is to provide a kind of installation sealing structure of steering column bearing, solves existing steering column and bearing fit discontinuity, the bad problem of bearing seal simultaneously.
The utility model solves the technological scheme that its technical problem adopts: a kind of installation sealing structure of steering column bearing, comprise mandrel and column jecket, and be arranged on the bearing between mandrel and column jecket, the spacing boss of bearing and riveting pin deck are set on column jecket; Below bearing, be provided with the Sealing shield ring sealing, Sealing shield ring coordinates with riveting pin deck.
For making the stressed even of bearing, described riveting pin deck is circumferentially evenly provided with at least 4 along column jecket.
For improving sealing, described Sealing shield ring and mandrel, Sealing shield ring and column jecket are interference fit.
Further, described Sealing shield ring comprises rubber sheath and annular sheet metal.
For reducing assembly force, on the inner ring wall of described Sealing shield ring, be provided with saw tooth structure.
The beneficial effects of the utility model: compress bearing by Sealing shield ring, avoid the direct riveting of original riveting pin deck on bearing, reduce the press control requirement of power of each riveting pin deck, make the stressed more even of bearing, can effectively prevent that the improper steering torque causing of column jecket riveting power control is excessive, turn to the faults such as abnormal sound.And Sealing shield ring can play good seal action to bearing, water proof and dust proof, the working life of improving steering column.
Below with reference to drawings and Examples, the utility model is described in detail.
Brief description of the drawings
Fig. 1 is sectional view of the present utility model.
Fig. 2 is Sealing shield ring sectional view.
In figure, be labeled as: 1, mandrel, 2, column jecket, 21, boss, 22, riveting pin deck, 3, bearing, 4, Sealing shield ring, 41, rubber sheath, 42, annular sheet metal, 43, saw tooth structure.
Embodiment
Embodiment, as shown in Figure 1 and Figure 2, a kind of installation sealing structure of steering column bearing, comprises mandrel 1 and column jecket 2, is arranged on the bearing 3 between mandrel 1 and column jecket 2, and the spacing boss of bearing 3 21 and riveting pin deck 22 are set on column jecket 2; Below bearing 3, be provided with the Sealing shield ring 4 sealing, Sealing shield ring 4 coordinates with riveting pin deck 22.Riveting pin deck 22 circumferentially evenly arranges and has 4 at least along column jecket 2.Described bearing 3 is rubber needle bearing.
The lower end of column jecket 2 is evenly distributed with riveting pin deck 22 everywhere, directly presses on the lower annular tinsel 42 of Sealing shield ring 4, and the power that is pressed in bearing 3 bottoms by Sealing shield ring 4 is evenly distributed, and has reduced the control requirement of the power that presses of riveting pin deck 22 everywhere; Can effectively prevent that the improper steering torque causing of column jecket 2 riveting power control is excessive, turn to the faults such as abnormal sound.
The inner circle interference fit of the cylindrical of Sealing shield ring 4 and column jecket 2, the saw tooth structure 43 of the inner circle of Sealing shield ring 4 and the cylindrical interference fit of mandrel 1, realize the protective action to bearing 3, avoids entering of water and dust, improves the working life of steering column.
