Description
Technical field
The utility model relates to Automotive Steering Technology, is specifically related to the device eliminating turn inside diameter noise.
Background technology
Now commercially many vehicle automobile steering systems, bearing coordinates with steering swivel by press-fiting, and bearing is connected with wheel hub, and wheel hub is connected with wheel again, realizes functions such as travelling and turn to.Because the bearing mounting hole of steering swivel or bearing exist working accuracy problem, easily there is high site or salient point or inclination in bearing mounting hole inwall or bearing surface; Bearing and bearing mounting hole coordinate when installing, and due to the existence of high site or salient point or inclination, bearing and bearing mounting hole inwall easily occur a bit or end thereof contacts, cause steering swivel and bearing fit bad; Vehicle, in turning process, can cause bearing to occur slight wriggling, when vehicle is close to cornering limit, turning abnormal sound can occur; Cause bearing inordinate wear, bearing can significantly reduce service life simultaneously.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides and can effectively eliminate turning abnormal sound, and can extend the device of the elimination turn inside diameter noise in bearing service life.
To achieve these goals, the technical solution adopted in the utility model is:
Eliminate the device of turn inside diameter noise, the steering swivel system of described vehicle comprises steering swivel, steering swivel installs bearing, the wheel hub be connected with wheel flutter and bearing connect, arrange inner groovy at the bearing mounting hole inwall of steering swivel, described bearing and bearing mounting hole inwall are at inner groovy position at least two-point contact.
As a kind of scheme, described inner groovy is arc, and arc concave shape groove is more than one; Or inner groovy is arc, be distributed in the same inner groovy circumferentially of bearing mounting hole inwall and form one group, arc concave shape groove is more than one group.
Alternatively, described inner groovy is annular, and interior annular groove is more than one.
Described inner groovy cross section is arc or triangle or oblong or trapezoidal.
Inner groovy to equidistantly distribute on bearing mounting hole inwall or distance unequal distribution on bearing mounting hole inwall.
The utility model has the advantage of: the device of this elimination turn inside diameter noise, by the bearing mounting hole inwall at steering swivel, inner groovy is set, make bearing and bearing mounting hole inwall at least two-point contact, be equivalent to bearing two ends are all effectively contacted with bearing mounting hole inwall; In turn inside diameter process, bearing two ends stress balance, can eliminate bearing crawl by actv., thus reach the object eliminating turning abnormal sound.The utility model not only structure is simple, and the mated condition of bearing and steering swivel can be made to promote, steering swivel and bearing fit more reliable and more stable, the effectively problem of solution turn inside diameter abnormal sound; Simultaneously due to bearing two ends stress balance, bearing inordinate wear reduces, and service life significantly promotes.

Mark in above-mentioned figure is:
1, steering swivel, 2, bearing, 3, bearing mounting hole, 4, inner groovy.
Detailed description of the invention
Contrast accompanying drawing below, by the description to optimum embodiment, detailed description of the invention of the present utility model is described in further detail.
As shown in Figures 1 and 2, eliminate the device of turn inside diameter noise, the steering swivel system of vehicle comprises steering swivel 1, steering swivel 1 is installed bearing 2, bearing 2 connects wheel hub, wheel hub is connected with wheel flutter again, arranges inner groovy 4 at bearing mounting hole 3 inwall of steering swivel 1, and bearing 2 and bearing mounting hole 3 inwall are at inner groovy 4 position at least two-point contact.
As a kind of embodiment, inner groovy 4 is arc, and inner groovy 4 is more than one, and inner groovy 4 can be one, two or more multiple; Or inner groovy 4 is arc, be distributed in the same inner groovy 4 circumferentially of bearing mounting hole 3 inwall and form one group, inner groovy 4 is more than one group.Inner groovy 4 can be one group, two groups or more than two many groups; Inner groovy 4 is in the same circumferentially discontinuous distribution of bearing mounting hole 3 inwall.Bearing 2 is each or often organize inner groovy more than 4 two Multi-contacts with bearing mounting hole 3 inwall, and in turn inside diameter process, bearing 2 two ends stress balance, can eliminate bearing 2 crawl by actv., thus elimination turning abnormal sound.
As another embodiment, or inner groovy 4 is annular, and interior annular groove 4 is more than one.Inner groovy 4 is in the same circumferentially continuous distribution of bearing mounting hole 3 inwall.Bearing 2 and each inner groovy of bearing mounting hole 3 inwall more than 4 two Multi-contacts, in turn inside diameter process, bearing 2 two ends stress balance, can eliminate bearing 2 crawl by actv., thus eliminate turning abnormal sound.
Inner groovy 4 cross section is arc or triangle or oblong or trapezoidal; Inner groovy 4 cross sectional shape is selected according to actual needs.
Inner groovy 4 is by forging or cast or extrusion forming; Inner groovy 4 can be forging, the straight formings such as casting or extruding, also can be formed by following process; Inner groovy 4 processing and fabricating is convenient, and cost is low.
Inner groovy 4 to equidistantly distribute on bearing mounting hole 3 inwall or distance unequal distribution on bearing mounting hole 3 inwall; Arc concave shape groove 4 according to actual needs evenly or be non-uniformly distributed on bearing mounting hole 3 inwall, or interior annular groove 4 according to actual needs evenly or be non-uniformly distributed on bearing mounting hole 3 inwall, ensure that bearing 2 and bearing mounting hole 3 inwall are at inner groovy 4 position at least two-point contact, make bearing 2 in steering procedure, uniform force.
Eliminate the device of turn inside diameter noise, inner groovy 4 is set by bearing mounting hole 3 inwall at steering swivel 1, makes bearing 2 and bearing mounting hole 3 inwall at least two-point contact, be equivalent to bearing 2 two ends are all effectively contacted with bearing mounting hole 3 inwall; In turn inside diameter process, bearing 2 two ends stress balance, can eliminate bearing 2 crawl by actv., thus reach the object eliminating turning abnormal sound; The utility model not only structure is simple, and the mated condition of bearing 2 and steering swivel 1 can be made to promote, and steering swivel 1 and bearing 2 coordinate more reliable and more stable, effectively solves the problem of turning abnormal sound; Simultaneously due to bearing 2 two ends stress balance, bearing 2 inordinate wear degree reduces, and service life significantly promotes.
Obvious the utility model specific implementation is not subject to the restrictions described above, as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out, all within protection domain of the present utility model.
