Described fixed end is semi-cylindrical in configuration, 2 fixed end outer walls is set with captive nut and makes 2 fixed end formation column structures close to each other; The column structure outer wall that fixed end described in 2 is formed be external diameter increase gradually stepped.
Further, for realizing the utility model better, the inwall of described through hole is regular hexagon structure.
Further, for realizing the utility model better, in the middle part of the linkage section sidewall described in 2, being respectively arranged with tapped through hole, in described tapped through hole, being respectively arranged with dowel bolt.
Further, for realizing the utility model better, described spindle arm body is provided with groove, described groove symmetry is established and is arranged in described spindle arm body both sides, and described groove is arranged along described spindle arm body length direction.
Further, for realizing the utility model better, described through-hole wall is provided with gasket layer.
The utility model compared with prior art, has following beneficial effect:
(1) the utility model matches with pitman arm by adopting orthohexagonal through-hole structure, when adopting orthohexagonal pitman arm, can make to be not easy to occur relative motion between spindle arm and pitman arm, making its fixed effect better;
(2) the utility model fixes two fixed ends by adopting captive nut, two fixed ends can be made to drive coupled linkage section bonded to each other, realize fixed effect, meanwhile, owing to adopting nut structure, can facilitate install and adjust;
(3) the utility model is by adopting the fixed end of the stepped structure of outer wall, can select captive nut as required, convenient installation, and meanwhile, the size of convenient adjustment through hole, can matching with pitman arm better, it is fixing to realize.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, be briefly described to the accompanying drawing used required in embodiment below, be to be understood that, the following drawings illustrate only some embodiment of the present utility model, therefore the restriction to scope should be counted as, for those of ordinary skill in the art, under the prerequisite not paying creative work, other relevant accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model integral structure schematic diagram.
Wherein: 101. spindle arm bodies, 102. connecting bores, 103. linkage sections, 104. fixed ends, 105. through holes, 106. captive nuts, 107. dowel bolts, 108. grooves, 109. gasket layer.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
As shown in Figure 1, a kind of automotive steering arm, comprise spindle arm body 101 and be arranged on the connecting end portion of spindle arm body 101 one end, described spindle arm body 101 is provided with connecting bore 102 away from described connecting end portion one end;
Described connecting end portion comprises the through hole 105 being provided with groove in the middle part of 2 symmetrically arranged linkage sections 103 and the linkage section 103 described in fixed end 104,2 that is connected with linkage section 103 and making to be formed in the middle part of 2 linkage sections 103 for clamping pitman arm;
Described fixed end 104 is semi-cylindrical in configuration, 2 fixed end 104 outer walls is set with captive nut 106 and makes 2 fixed end 104 formation column structures close to each other; The column structure outer wall that fixed end 104 described in 2 is formed be external diameter increase gradually stepped.
When mounted, be sleeved on by pitman arm in through hole, select the captive nut matched with fixed end external diameter, being sleeved on by captive nut on the cylinder of 2 fixed ends formation, is that two linkage sections and pitman arm fit.
Due to the stepped fixed end structure adopting external diameter to increase gradually, captive nut installation site can be selected as required, thus the distance between position adjustments 2 fixed ends installed by captive nut, and then effectively regulate the size of through hole, the laminating degree between adjustment pitman arm and through-hole wall.
Embodiment 1:
Further preferably, in the present embodiment, the inwall of described through hole 105 is regular hexagon structure.Because through-hole wall is regular hexagon structure, therefore, when pitman arm to be sleeved in through hole and to fit with through-hole wall, pitman arm is less likely to occur to relatively rotate, and effectively avoids it to relatively rotate bringing the phenomenon of transmission timeliness.
In order to prevent changing spindle arm and pitman arm during wearing and tearing, in the present embodiment, described through hole 105 inwall is provided with gasket layer 109.When there is Relative friction between spindle arm body and pitman arm, by the wearing and tearing of gasket layer, avoid changing spindle arm body or pitman arm.
Embodiment 2:
In order to realize the position adjusting pitman arm, in the present embodiment, in the middle part of linkage section 103 sidewall described in 2, being respectively arranged with tapped through hole, in described tapped through hole, being respectively arranged with dowel bolt 107.Dowel bolt 107 one end is pushed up to be pressed on the outer wall of pitman arm, can be realized the adjustment of pitman arm position in through-holes by the position adjusting dowel bolt 107 respectively.
In order to reduce the weight of spindle arm body, in the present embodiment, described spindle arm body 101 is provided with groove 108, and described groove 108 symmetry is established and is arranged in described spindle arm body 101 both sides, and described groove 108 is arranged along described spindle arm body 101 length direction.By arranging groove, the while of can realizing powerdriven, the weight of spindle arm body being reduced, contributes to transmission of power, meanwhile, save material, convenient processing.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
