Description
Technical field
The utility model relates to automobile spherical hinge assembly design field, relates in particular to a kind of spherical hinge assembly, specifically is applicable to prevent that the spring slippage from causing damage to the ball bowl.
Background technique
The major function of spherical hinge assembly is to satisfy relative movement complicated between two articulated elementss, and it is generally used on the rod member of steering gear.For the gap that the surface abrasion of eliminating owing to the hinged place produces, generally adopt spring in modern times in the design of spherical hinge assembly along ball stud axis compressing structure, referring to Fig. 1; When ball stud 1 received axial force, spring 7 can be compressed distortion, at this moment; If spring 7 lacks along the guide structure on ball stud 1 axial direction; Then spring 7 can produce slippage because of unbalance stress, rubs thereby produce with the surface of contact of play ball bowl 5, and sends abnormal sound; And then following ball bowl 5 caused damage, when serious even can shorten working life of spherical hinge assembly.
The Chinese patent notice of authorization number is CN201424050U; Notice of authorization day is that the utility model patent on March 17th, 2010 discloses a kind of steering ball end, comprises spherical shell and ball stud, and an end of this ball stud is positioned at outside the spherical shell; The other end is positioned at spherical shell; End in spherical shell has spherical bulb body, is provided with the lining lower body that carries the bulb body in the spherical shell, and the lining lower body is separated into spherical shell the last bunker and following bunker that can store lubricant oil; The bulb body is arranged in the bunker; In following bunker, be provided with its two ends and act on the spring on lining lower body and the spherical shell respectively, between last bunker and following bunker, be provided with and let the lubricant oil of time bunker enter into the oil inlet passage between bulb body and the lining lower body, on spherical shell, be provided with lubricant oil is circulated into the oil-feed structure in the bunker.Though this model utility has lubrication effect height, bulb body slow-roll stabilization, advantage that noise is little; But its spring that adopts is still with lining lower body (being equivalent to ball bowl down) and directly contacts; In case ball stud receives axial force; Slippage then can take place in spring, is prone to produce friction with lining lower body (being equivalent to ball bowl down), and it is caused damage.
Summary of the invention
The purpose of the utility model is to overcome the spring easy glide that exists in the existing technology, thereby the defective and the problem of ball bowl under the easy damaged, not easy glide of a kind of spring is provided, thereby can damage down the spherical hinge assembly of ball bowl.
For realizing above purpose, the technical solution of the utility model is: a kind of spherical hinge assembly comprises ball stud and ball cup; The top of said ball cup is provided with dust-proof cover; Set inside has last ball bowl, following ball bowl, and the bottom is provided with Elastic forming board, and an end of ball stud is positioned at the outside of ball cup; The bulb of the other end behind dust-proof cover with last ball bowl, the following ball bowl-type matching pair that becomes to trackslip, and playing between ball bowl and the Elastic forming board be provided with spring;
The said two ends of ball bowl down are respectively arranged with coaxial rounded channels and column type groove, match with the outside of bulb in the inside of rounded channels, match with the outside of spring in the inside of column type groove.
The inside diameter of said column type groove is than 3 millimeters of big 1 – of outer dia of spring.
Said rounded channels communicates with the column type groove through middle groove.
The inside diameter of said middle groove is than 8 millimeters of little 5 – of inside diameter of column type groove.
Compared with prior art, the beneficial effect of the utility model is:
1, being respectively arranged with coaxial rounded channels and column type groove at the two ends of following ball bowl in a kind of spherical hinge assembly of the utility model, matches with the outside of bulb in the inside of rounded channels, matches with the outside of spring in the inside of column type groove; With the column type groove as spring along the guide structure on the ball stud axial direction, at this moment, the guide structure of rounded channels and spring is same integral body just; During use; When ball stud receives axial force, though spring can be compressed distortion, because its top is limited in the inside of column type groove; About spring or move forward and backward all and be controlled within the technological requirement by the column type groove; Can not produce slippage, thus the frictionally damage of effectively avoiding the spring slippage that following ball bowl is caused, and then prolong the working life of ball bowl down.Therefore the utility model can avoid spring generation slippage to damage down the ball bowl, can prolong the working life of ball bowl down.
Description of drawings
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is the structural representation of the utility model.
Fig. 3 is the structural representation of following ball bowl among Fig. 2.
Among the figure: ball stud 1, bulb 11, ball cup 2, dust-proof cover 3, last ball bowl 4, following ball bowl 5, rounded channels 51, column type groove 52, Elastic forming board 6, spring 7, middle groove 8.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is done further detailed explanation.
Referring to figure 2 – Fig. 3, a kind of spherical hinge assembly comprises ball stud 1 and ball cup 2; The top of said ball cup 2 is provided with dust-proof cover 3; Set inside has last ball bowl 4, ball bowl 5 down, and the bottom is provided with Elastic forming board 6, and an end of ball stud 1 is positioned at the outside of ball cup 2; The bulb 11 of the other end with last ball bowl 4, ball bowl 5 forms the matching pair that trackslips down, and is being provided with spring 7 between ball bowl 5 and the Elastic forming board 6 down behind dust-proof cover 3;
The said two ends of ball bowl 5 down are respectively arranged with coaxial rounded channels 51 and column type groove 52, match with the outside of bulb 11 in the inside of rounded channels 51, match with the outside of spring 7 in the inside of column type groove 52.
The inside diameter of said column type groove 52 is than 3 millimeters of big 1 – of outer dia of spring 7.
Said rounded channels 51 communicates with column type groove 52 through middle groove 8.
The inside diameter of said middle groove 8 is than 8 millimeters of little 5 – of inside diameter of column type groove 52.
During use; The rounded channels 51 of following ball bowl 5 one ends and bulb 11 closely cooperate with the formation matching pair that trackslips; The column type groove 52 of the other end closely cooperates spring 7 is played along the leading role on ball stud 1 axial direction with an end of spring 7, and when ball stud 1 received axial force, spring 7 was compressed distortion; But its distortion caused about or move forward and backward all and be controlled within the technological requirement by column type groove 52; Thereby slippage can not take place, just can not cause frictionally damage yet, thereby prolong the working life of time ball bowl 5 following ball bowl 5.The inside diameter of column type groove 52 is generally 2 millimeter, too narrow difficult assembling, the too wide using effect that then influences than 3 millimeters of big 1 – of outer dia of spring 7.
Therefore the utility model can not only avoid spring generation slippage damaging down the ball bowl, and can prolong the working life of ball bowl down.
