Description
Technical field
The utility model relates to a kind of bearing, especially a kind of bearing that is used on the automobile front lamp.
Background technique
At present, increasing safety installation have been installed on the automobile, this wherein also comprises important lighting set, as the follow-up steering Headlamps, also claim to turn to automatically Headlamps, it can be according to the vehicle steering wheel angle, the variation of the yaw velocity and the speed of a motor vehicle, constantly Headlamps is carried out dynamic adjustments, keep the Headlamps direction consistent with the current driving direction of automobile, this technology has solved automobile illumination and direction of travel inconsistent " vision blind spot " problem when turning night, the driver can see the road conditions of curve ahead inboard in advance, makes driving at night become safer.Key in the follow-up steering front lamp device then is a bearing wherein, and the flexibility of its running directly affects the flexibility and the accuracy of follow-up steering Headlamps, and then influences the Security that automobile was turned at night.The bearing ubiquity complex structure that uses on present these follow-up steering Headlampss, the relatively poor problem of flexibility of running.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of flexibility simple in structure, running is good, the flexibility that helps to improve the follow-up steering Headlamps and accuracy and then influence be used for bearing automobile front lamp on of automobile in the Security of turning at night.
The technological scheme that provides according to the utility model, outer ring body and the socket of inner ring body ring-type, on inner ring body, be provided with installation axle hole, the relative wall of outer ring body and inner ring body offers cell body and forms circular raceway, be provided with rolling element in the raceway, be provided with retainer between the rolling element, rolling element will separate between outer ring body and the inner ring body and form ring-shaped cavity, between the relative wall of the outer ring body of this cavity and inner ring body, the rolling element both sides are provided with dust ring, offer groove at the end face of inner ring body round installation axle hole.
The outer of described dust ring is provided with crimping, and in the mounting groove of the ring-type that crimping embedding outer ring body inwall is offered, the interior edge of dust ring is provided with flange.Described flange is oppositely arranged and points to rolling element.Distance embeds the degree of depth in the mounting groove less than crimping between flange and the inner ring body outer wall.Mounting groove near a sidewall of rolling element is being upright side walls perpendicular to the axis of installation axle hole, and mounting groove is a lead-in chamfered at the sidewall away from rolling element, and described crimping rests on upright side walls and the lead-in chamfered.
The utility model is simple in structure, and the flexibility of running is good, helps to improve the flexibility of follow-up steering Headlamps and accuracy and then influences the Security that automobile was turned at night.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: described bearing comprises the outer ring body 1 and inner ring body 2 of ring-type socket, inner ring body 2 is provided with installation axle hole 3, relative wall's (being the outer wall of the internal face and the inner ring body 2 of outer ring body 1) of outer ring body 1 and inner ring body 2 offers cell body and forms circular raceway, be provided with rolling element 4 in the raceway, be provided with retainer 5 between the rolling element 4, rolling element 4 will separate between outer ring body 1 and the inner ring body 2 and form ring-shaped cavity, between the relative wall of the outer ring body 1 of this cavity and inner ring body 2, rolling element 4 both sides are provided with dust ring 6, end face at inner ring body 2 offers groove 7 round installation axle hole 3, and the shape of this groove 7 preferably is the circle concentric with installation axle hole 3.
The outer of dust ring 6 is provided with crimping 8, in the mounting groove 9 of the ring-type that crimping 8 embedding outer ring bodies 1 inwall is offered, the interior edge of dust ring 6 is provided with flange 10, flange 10 is oppositely arranged and points to rolling element 4, distance embeds the degree of depth in the mounting grooves 9 less than crimping 8 between flange 10 and inner ring body 2 outer walls, make this bearing in use dust ring 6 can not come off.
After this Bearing Installation use, the follow-up steering Headlamps it can be according to the variation of vehicle steering wheel angle, yaw velocity and the speed of a motor vehicle, constantly Headlamps is carried out dynamic adjustments, keep the Headlamps direction consistent with the current driving direction of automobile, automobile illumination and direction of travel inconsistent " vision blind spot " problem when turning night have been solved, the driver can see the road conditions of curve ahead inboard in advance, makes driving at night become safer.
The fatten amount of bearing of the present utility model lacking very, grease is in order to allow the bearing could rotation flexibly under this moment of torsion less, thereby guarantees the effect that turns to of automobile front!
The axial internal clearance and the radial internal clearance of the utility model bearing are all very little, and play is the adjusting lamp distance of preparing more for the headlight that can guarantee automobile for a short time!
