Below with reference to Fig. 1-Fig. 2 detailed description according to the control arm component 10 of the utility model embodiment.
Shown in referring to Fig.1, the control arm component 10 according to the utility model embodiment may include: that control arm 1, bushing are total
At 2 and fixing piece 3.
Control arm 1 has control arm pin shaft 11 and control arm body 12, and control arm pin shaft 11 is stretched from control arm body 12
Out, and control arm pin shaft 11 is fixedly linked with control arm body 12.Specifically, control arm pin shaft 11 may include: anti-rotation section 111
With fixed section 112, the outer diameter of fixed section 112 is not more than the outer diameter of anti-rotation section 111.As shown in Figure 1, perpendicular to control
On the cross section of 11 axis of arm pin shaft processed, the cross section of anti-rotation section 111 is regular hexagon, and the cross section of fixed section 112 is circle,
The outer diameter of fixed section 112 is not more than the inscribed circle size of anti-rotation section 111, thus can guarantee that anti-rotation section 111 can be total with bushing
At 2 cooperations, and fixed section 112 can pass through bush Assembly 2.
Bush Assembly 2 may include: bushing mounting base 21 and bushing 22, and bushing installation is provided in bushing mounting base 21
Hole, bushing 22 are arranged in bushing mounting holes, and bushing 22 has anti-rotating hole 221, and anti-rotation section 111 wears cooperation in anti-rotating hole 221
It is interior, the diametrically opposite position of anti-rotation section 111 Yu bushing 22 is thus limited, to prevent control arm pin shaft 11 and bushing 22 from occurring
It relatively rotates, and at least part of fixed section 112 is pierced by from anti-rotating hole 221.
Fixing piece 3 is fixed on fixed section 112 and is pierced by the part of bushing 22, to complete control arm pin shaft 11 and bushing 22
Fastening.
When assembly controls arm component 10, first control arm 1 and bush Assembly 2 are assembled together, that is, make anti-rotation section
111 cooperate with anti-rotating hole 221, are pierced by least part of fixed section 112 out of anti-rotating hole 221, then again consolidate fixing piece 3
It is scheduled on fixed section 112 to be pierced by the part of bushing 22, and tightens fixing piece 3 to regulation moment values, in this way, controlling arm component 10
Each components position is accurate, reliable, can effectively solve the problems, such as the abnormal sound of control arm component 10.
As shown in Figure 1, bushing 22 can be assemblied on control arm pin shaft 11 according to direction shown in arrow A, and in other words, control arm
Pin shaft 11 wears bushing 22 from left to right, and fixed section 112 is pierced by the right end of bushing 22, and fixing piece 3 is fixed on fixed section 112.
According to the control arm component 10 of the utility model embodiment, by be arranged on control arm pin shaft 11 anti-rotation section 111,
Anti-rotating hole 221 is set in bushing 22, it is ensured that it does not relatively rotate between bushing 22 and control arm pin shaft 11, thus
When tightening fixing piece 3, bushing 22 will not follow rotation, thus the screw-down torque of fixing piece 3 can be made to reach design requirement, kept away
Exempt from bushing 22 in driving conditions and rotates caused abnormal sound.
Preferably, the length of anti-rotation section 111 is less than the length of bushing 22, thus can guarantee at least one of fixed section 112
Dividing can be located in bushing 22, in this way, can make fixing piece 3 and bushing 22 when fixing piece 3 to be tightened on fixed section 112
Right end fitting, so that control arm 1 and bush Assembly 2 are securely fixed together.
Specifically, bushing 22 may include: bushing outer tube, rubber tube and bushing inner tube, bushing outer tube and bushing mounting holes
Cooperation, rubber tube are arranged between bushing outer tube and bushing inner tube, have the anti-rotating hole 221 in bushing inner tube.As shown in Fig. 2,
Controlling arm component 10 after the assembly is completed, fixing piece 3 is directly contacted with bushing inner tube.By the way that rubber tube is arranged, lining can be improved
The overall stiffness of set 22.
In some alternative embodiments, bushing outer tube, rubber tube and bushing inner tube can be filled by dismountable mode
It is interference fit with together, such as between rubber tube and bushing inner tube, is also interference fit between rubber tube and bushing outer tube,
Be conducive to subsequent replacement vulnerable part in this way.
And in other optional embodiments, bushing outer tube, rubber tube and the vulcanization of bushing inner tube are structure as a whole, in this way
22 structure of bushing it is simple, and bushing 22 is assemblied in bushing mounting holes as a whole, is conducive to save assembly process, be mentioned
High efficiency.It optionally, is interference fit between bushing 22 and bushing mounting holes.
In the embodiment shown in fig. 1, the both ends of bushing 22 outwardly protrude the both ends of bushing mounting base 21, as a result, bushing
22 can play better guiding role for control arm pin shaft 11, while can guarantee that fixing piece 3 is only contacted with bushing 22, without
Encounter bushing mounting base 21.
Further, control arm component 10 can also include gasket 4, and gasket 4 is set on fixed section 112, and gasket 4 is set
It sets between fixing piece 3 and bushing 22.By the way that gasket 4 is arranged, fixing piece 3 can be made more equal to the pressing force distribution of bushing 22
It is even, to mitigate stress concentration phenomenon.
Anti-rotation section 111 is non-circular shaft, and anti-rotating hole 221 is the non-circular hole cooperated with the non-circular shaft.Such as in some embodiments
In, anti-rotation section 111 is square axis, and anti-rotating hole 221 is square hole；Or anti-rotation section 111 is elliptical shaft, anti-rotating hole 221 is ellipse
Hole.
In the embodiment shown in fig. 1, anti-rotation section 111 is six square shafts, and anti-rotating hole 221 is hexagonal hole.Mentioned here " six
Side " refers to that cross section is regular hexagon.That is, anti-rotation section 111 and anti-rotating hole 221 are in the cross section perpendicular to own axes
On be in regular hexagon.
Fixed section 112 is external thread section, and fixing piece 3 is locking nut, and locking nut is suitable for the external screw thread with fixed section 112
Threaded.
According to the vehicle of the utility model another aspect embodiment, the control arm component 10 including above-described embodiment.And it is right
