Embodiment
MacPherson strut is symmetrical structure, in the present embodiment, the left side structure of a discussion suspension.From
It can be readily derived in the description of left side structure and its symmetrical right side structure.
As shown in figure 1, a kind of MacPherson strut structure is main by vibration damper complement 2, knuckle 3, lower swing arm sheet
Body 5, steering wheel hub 4, stabilizer link 71, stabiliser bar 72 are constituted.Vibration damper complement 2 is made up of spring 1 and damper bracket, its
Middle spring 1 have passed through eccentric processing.When spring 1 is set in the outside of damper bracket, and press-fited in special frock
Afterwards, spring 1 forms vibration damper complement 2 with damper bracket.Also, the central axis of the damper bracket and the bullet
The central axis of spring 1 is misaligned, and both central axis are deviated from each other.This can effectively reduce vibration damper complement 2 and be rushed
Side force when hitting.
As shown in Fig. 2 one end of knuckle 3 is bolted connection with vibration damper complement 2.The other end of knuckle 3
Pass through ball pin support 9 and the movable connection of the bottom arm body 5.In the another of relative knuckle 3 and the connecting side of vibration damper complement 2
Side, knuckle 3 has upper and lower two tie points.Define that a receiving is empty between the upper tie point 31 and lower tie point 32
Between, steering wheel hub 4 is rotatably arranged on the receiving space.Steering wheel hub 4 by bolt respectively with the upper tie point 31
It is fastenedly connected with the lower tie point 32.The line of upper tie point 31 and lower tie point 32 is exactly the rotation axis of steering wheel hub 4
10.The line offset vertical direction predetermined angular of the upper tie point 31 and the lower tie point 32, therefore the steering wheel hub 4
Rotation axis 10 direction also offset vertical direction predetermined angular.Rotation is provided between upper tie point 31 and lower tie point 32
Rotating shaft, bearing is provided with the rotary shaft and is rotated with assisted diversion wheel hub 4.In this embodiment, the bearing is biserial circle
Taper roller bearing (not shown).
As shown in figure 1, bottom arm body 5 is lower swing arm Triangular Arm, with the outer end with ball pin and the inner with bushing.Under
The inner of swing arm body 5 is fastenedly connected by bolt with subframe 8.And connect the outer end and the inner Triangular Arm arm body
Provided with multiple installation sites.Also, bottom arm body Triangular Arm arm body has an installation site to be also connected with subframe 8.
As shown in Fig. 2 the band ball pin outer end of bottom arm body 5 is connected by ball pin support 9 with knuckle 3.In existing skill
In art, the mounting column point 21 of vibration damper complement 2 is virtual pivot with the line with ball pin outer end center of bottom arm body 5
Line 11.It can be clearly seen that from figure, the rotation axis 10 is relative to the virtual pivot line 11 toward lateral deviation outside vehicle body
Move.Core wheel (not shown), tire earth point (not shown) to the distance of rotation axis 10 rotate compared to it away from virtual
Axis 11 is shorter, therefore rotation axis 10 causes the radius of turn of tire during automobile turning to diminish.It is unfavorable to be produced at tire
When power and torque ripple, smaller radius of turn can greatly reduce the generation of the steering wheel jitter phenomenon thus brought, it is ensured that
The stability of automobile chassis.Therefore, rotation axis 10 can solve the problem that vehicle because radius of turn is excessive and can not be narrow in part
On alleyway road the problem of convenient turning and u-turn, the vehicle improved in city proper passes through property.
As shown in figure 3, in order to which restricting vehicle tire rotates around virtual pivot line 11 (referring to Fig. 2), it is ensured that rotation axis
10 effect, is additionally provided with the drawing for forbidding the knuckle 3 to rotate between the bottom arm body 5 and the knuckle 3
Bar 6.Therefore, pull bar 6 is provided between the installation site of ball pin support 9 and the interlude of bottom arm body 5.The pull bar 6 is
Rigid structure, with first end and the second end.The installation site of the first end and the interlude of bottom arm body 5
By ball pin hinge connection, the tie point is the tie point B of pull bar and bottom arm body.The second end and the ball pin branch
Frame 9 is connected by ball pin, and the tie point is the tie point C of pull bar and ball pin support.And as it was previously stated, bottom arm body 5 passes through
Ball pin support 9 is connected with knuckle 3, i.e. the tie point bottom arm body 5 the ball pin center with ball pin outer end, be A points.
Therefore, above-mentioned section A-B, B-C sections, C-A sections constitute stable triangular structure, equivalent to arm body, the pull bar of bottom arm body 5
6th, ball pin support 9 constitutes stable triangular structure, limits the rotation of the knuckle 3.Rotation axis 10 and above-mentioned three
The MacPherson strut structure that angular structure is bonded enables to tire to be rotated around rotation axis 10, it is to avoid wheat is not
There is the phenomenon of overlapping coupling in the divertical motion of inferior formula independent suspension.
As shown in figure 1, the steering wheel hub 4 has steering arm 12, the steering arm 12 is used to be connected with steering mechanism.Turn
It is steering wheel to mechanism.Therefore, human pilot controls the rotation of steering wheel hub 4 by the steering mechanism being connected with steering arm 12,
So as to control tire.
As shown in Fig. 2 because the presence of rotation axis 10 causes the kingpin inclination, king pin offset, master of whole suspension
Pin back rake angle can be adjusted on demand, so that improve steering force, steering reversal performance and increase insensitivity
Deng all kinds of performances in chassis.And all kinds of parameters and performance except suspension can be set as required, it can also be ensured that vehicle
Cost, can meet the demand in front deck space again, meet the arrangement of power assembly.After increase rotation axis 10, required property
Energy index can individually be quantified, and chassis performance has obtained great lifting.
As shown in Fig. 2 including stabiliser bar 72 and stabilizer link 71.One end of the stabilizer link 71 and the vibration damping
The movable connection of device assembly 2, the other end of the stabilizer link 71 and the movable connection of the stabiliser bar 72.The stabiliser bar
72 are fixed on vehicle body by mounting bracket.The two ends of the stabiliser bar 72 pass through stabilizer link 71 and left side shock absorber respectively
Assembly, the connection of right side vibration damper complement.
So far, although those skilled in the art will appreciate that herein it is detailed have shown and described it is of the present utility model many
Individual exemplary embodiment, still, still can be public according to the utility model in the case where not departing from the utility model spirit and scope
The content opened directly determines or derived many other variations or modifications for meeting the utility model principle.Therefore, this practicality is new
The scope of type is understood that and regarded as to cover other all these variations or modifications.
