Described lower end choke 112 is provided with circlip groove 113; The lower end choke 112 of described dust-proof cover 11 embeds in the binding groove 145 on described housing 14; And be provided with in the circlip groove 113 that a shaft block ring 12 snaps on described lower end choke 112, make described shaft block ring 12 and described circlip groove 113 interference fit.
As preferred embodiment, on housing 14, (housing 14 lower end shown in figure) is provided with a stepped part 141, described housing 14 is fitted in the mounting hole 21 of this swing arm body 2, described swing arm body 2 between described binding groove 145 and described stepped part 141, by the restriction of described stepped part 141 and described shaft block ring 12.Concrete, described swing arm body 2 comprises upper-end surface 22 and external cylindrical surface 24; The upper-end surface 22 of described swing arm body 2 is concordant with the lower groove face 144 of described binding groove 145.Adopt this kind of decision design, ball stud 13 will from (moving down) during the opposite direction pull-off be pressed into, the non deformable reason of rigidity due to shaft block ring 12, the housing 14 of shaft block ring 12 with ball stud assembly 1 in binding groove 145 moves down, and contact on the upper-end surface 22 of swing arm body 2 below shaft block ring 12, be subject to it to stop, so ball stud assembly 1 can not move down pull-off; Effectively swing arm body 2 can be limited between described stepped part 141 and binding groove 145.
As preferred embodiment, also can form turnup structure 114 at the end of described lower end choke 112, described turnup structure 114 wraps up the lower groove face of described binding groove 145, the upper-end surface 22 of described swing arm body 2 and external cylindrical surface 24 top.Owing to being provided with this turnup structure 114 on described lower end choke 112, be conducive to the installation of shaft block ring 12, when assembling shaft block ring 12, shaft block ring 12 is guided by this turnup structure 114, from large mouth to osculum, achieve easily and shaft block ring 12 is fitted in circlip groove 113.
As shown in Figure 2, the inner sulfuration of upper end choke 111 of described dust-proof cover 11 has eyelet 111a, and the upper end choke 111 of described anti-layer cover is sleeved on outside ball stud 13 by a bracing ring 111b.Concrete, in conjunction with this figure, namely the upper end choke 111 of so-called anti-layer cover is sleeved on this ball pin bar 130.As shown in FIG., the cross section of described eyelet 111a is L-shaped, and the cross section of described bracing ring 111b is L-shaped.
Ball cup can be the monolithic construction of one, also can be split-type structural.Such as, in this example, this ball cup comprises ball cup 15 (or deserving to be called ball seat) and lower ball cup 16 (or claiming lower ball base), and described upper ball cup 15 and lower ball cup 16 coordinate formation spherical hollow space 18;
The bulb 134 of described ball stud 13 is fitted in described spherical hollow space 18.Meanwhile, in its spherical hollow space 18, go back extend oil lubricating grease, be used for playing the lubrication between ball stud 13 and ball cup.
About the mounting type of ball stud 13 with housing 14, mode well-known to those skilled in the art can be adopted, such as, can at described housing 14 lower ending opening, described opening flange riveted joint has bottom 17, is encapsulated in housing 14 by described ball cup.Concrete finger forms riveted joint flange 142 in housing 14 lower end.After bottom 17 is loaded, this riveted joint flange 142 being bent inwards, wrapping up support edge in the next week of bottom 17 along being formed.So, namely by this bottom 17, bulb 134, ball cup are arranged in this housing 14.
Meanwhile, in the upper end of this housing 14, form the upper shed of drawing ball stud, this upper shed place, slightly larger than the diameter of ball pin body, makes ball pin can swing within the scope of several angle, rotate.
As shown in Figure 3, this shaft block ring 12 is conventionally known to one of skill in the art, and it is generally the structure of endless belt jagged 122, simultaneously on both sides, breach 122 place, generally also being provided with attachment hole 121, stretching in hole by pliers during for installing, strut shaft block ring 12 and be installed to circlip groove 113.
Assembly process: as shown in Figure 1, when carrying out the assembling of ball stud assembly 1 and swing arm body 2, first by upper ball cup 15, loading housing 14, then ball pin is inserted from housing 14 lower ending opening, bulb 134 is fitted into upper ball cup 15 times, and then be fitted into lower ball cup 16, bottom 17 is loaded, then by the riveted joint flange 142 bottom housing 14, bottom 17 is riveted.Then the ball stud assembly 1 tentatively assembled is inserted the mounting hole 21 of swing arm body 2 from lower end, in the stepped part 141 that the lower end of swing arm body 2 is fixed on housing 14, then dust-proof cover 11 is inserted in from upper end, lower end choke 112 is embedded in binding groove 145, finally shaft block ring 12 is snapped in the circlip groove 113 on lower end choke 112, and realize interference fit.Swing arm ball pin assembly after assembling as shown in Figure 4.
The swing arm ball pin assembly that this example provides, owing to which employs a binding groove 145, is snapped in the lower end choke 112 of dust-proof cover 11 in this binding groove 145 by a shaft block ring 12, and makes described shaft block ring 12 and circlip groove 113 interference fit.So, do to simplify from structure, the groove of two in existing design has been united two into one, eliminated unnecessary groove, auxiliary clip and unnecessary operation, the effect serving same fastening anti-layer cover and prevent ball stud assembly 1 from coming off from swing arm body 2.Meanwhile, the interference fit of its shaft block ring 12 and circlip groove 113 makes this shaft block ring 12 pretension in circlip groove 113, effectively can prevent loosening, the ball pin pull-off of housing 14, thus improve the reliability of swing arm ball pin assembly.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
