Embodiment 1 to embodiment 4 is described in detail with reference to the accompanying drawing:
Embodiment 1
A kind of suspension control arm structure is present embodiments provided, please with reference to Fig. 1 to Fig. 4 in Figure of description.
As shown in Figure 1, the suspension control arm structure includes control arm 100；Control arm 100 includes the first connector 110, the
Two connectors 120, third connector 130, the 4th connector 140 and locating part 150, the first connector 110, the second connector
120, third connector 130 and the 4th connector 140 all have two tie points, i.e. the first tie point and the second tie point；The
The first tie point rotation axis of a connection piece 110 is at a distance from the second tie point rotation axis equal to the second connector 120
First tie point rotation axis is at a distance from the second tie point rotation axis；First tie point of the first connector 110, second connect
First tie point of fitting 120 and the first tie point of third connector 130 are articulated with a bit, and the second of the first connector 110
Second tie point of tie point, the second tie point of the second connector 120 and third connector 130 is all connected to locating part 150,
So that the rotation axis and third of the rotation axis of 110 second tie point of the first connector, 120 second tie point of the second connector
The rotation axis of 130 second tie point of connector is coplanar and parallel, the second tie point, the second connector of the first connector 110
Second tie point of 120 the second tie point and third connector 130 is conllinear along the plane projection of own rotation axis line；4th connects
First tie point of fitting 140 is articulated with the second tie point of the second connector 120,140 second tie point of the 4th connector
Rotation axis is at a distance from the rotation axis of 130 second tie point of third connector equal to the first connection of the 4th connector 140
Point rotation axis is at a distance from the second tie point rotation axis.
Specifically, which is reduced to structure as shown in Figure 4, SQ is equivalent to first company's part, and SP is suitable
Connect part in second, SO is equivalent to third and connects part, and PR is equivalent to the 4th connector 140.It crosses S point and makees ST ⊥ PQ in point T, due to SQ=
SP, then PT=QT.
OPOQ=(OT-PT) (OT+QT)
=(OT-PT) (OT+PT)
=OT2- PT2
=(OT2+ST2)-(PT2+ST2)
=OS2- SP2
The length of OS, SP are fixed, so OS2- SP2For constant, OS is enabled2- SP2=r2, so, P and Q are with O for circle
The inverse point of the heart, the circle that r is radius.The motion profile that Q can be learnt according to round deMorgan's theorem is straight line, it was demonstrated that as follows.

Distance is equal to the first tie point of the 4th connector 140 at a distance from the second tie point, then it is the center of circle that point P and point O, which is always positioned at R,
RP is on the circumference of radius.Tie point O and point R simultaneously extends, and meets at point W with circumference.A point V is looked on OR extended line, and then is made
OWOV=OPOQ is obtained, and connects QV.
Due to OWOV=OPOQ, then OW/OQ=OP/OV, while ∠ POW=∠ QOV, so, △ OVQ ∽ △ OWP,
And then ∠ OVQ=∠ OPW=90 °.
Due to OWOV=OPOQ=constant, OW=2RP, so, the position of V point is fixed and invariable.Meanwhile OQ
Direction is arbitrary, so the movement routine of Q point was the vertical line of V point, i.e. the movement of the second tie point of the first connector 110
Track is perpendicular to the rotation axis of 140 second tie point of the 4th connector and the rotary shaft of 130 second tie point of third connector
Line is formed by plane.
When the suspension control arm structure is installed on vehicle, the second tie point and the 4th connector 140 of third connector 130
The second tie point be articulated with vehicle frame, vehicle body or subframe, the rotation axis and third of 140 second tie point of the 4th connector connect
The rotation axis of 130 second tie point of fitting is formed by that plane is parallel to the ground, the second tie point of the first connector 110
Motion profile is perpendicular to the rotation axis of 140 second tie point of the 4th connector and the rotation of 130 second tie point of third connector
Shaft axis is formed by plane, so, the motion profile of the second tie point of the first connector 110 is perpendicular to ground.
Knuckle is connected to the second tie point of the first connector 110, and wheel is installed on knuckle, the irs control arm knot
Movement when structure makes wheel hop only perpendicular to ground, not along the movement of vehicle body transverse direction, and then reduces the envelope of tire
Face enables the size of car body and wheel cover plate to reduce, and increases interior space, while making wheel in bounce, and the grounding point of tire is not
Cross directional variations can occur, reduce the abrasion of tire.
Further, as shown in Figure 1, locating part 150 includes the 5th connector 151, the 6th connector 152 and the 7th connection
Part 153, the 5th connector 151, the 6th connector 152 and the 7th connector 153 all have two tie points, i.e. the first tie point
With the second tie point；First tie point of the 5th connector 151 connect point articulated with the first of the 6th connector 152；5th connects
Second tie point of fitting 151 connect point articulated, the second tie point of the 6th connector 152 with the second of the first connector 110
It is connect with the second of the second connector 120 point articulated；The rotation axis of first tie point of the 5th connector 151 is connect with second
Distance, the rotation axis of the first tie point of the 6th connector 152 and the rotation axis of the second tie point of the rotation axis of point
Distance be equal to the first connector 110 the first tie point rotation axis at a distance from the rotation axis of the second tie point；
