Description
Technical field
The invention belongs to suspension technical field, particularly relates to a kind of type front independent suspension mechanism.
Background technology
Automotive suspension is the vitals for ensureing riding comfort, meanwhile, automotive suspension is used as vehicle body (or vehicle frame) and car
Make the force transferring part for connecting between axle (or wheel), be the vitals for ensureing ride safety of automobile again.
Independent suspension is that the wheel of left and right two on an axletree by automobile is individually installed on vehicle body (or vehicle frame)
Under, vehicle bridge adopts breakaway-element, and middle one section is fixed on vehicle body (or vehicle frame), mutual not shadow when two sidecar wheel of independent suspension is hit
Ring, and as the sprung mass is relatively light, it is very strong with damping capacity to buffer, riding comfort is good, and indices are better than non-only
Vertical suspension, but independent suspension structure is complicated.
Vehicle four-wheel alignment is fewer now, mainly front-axle steering, and independent suspension is adopted the front axle of passenger car more, this
The independent suspension that a little and steering mechanism combines has macpherson suspension, double cross arm independent suspension, multi link independently to hang
Frame etc..Wherein lower swing arm affects very big to steering structure, as shown in Figure 1 in three kinds of configurations, in each configuration, upper figure is front suspension
Top view, figure below is rearview.
In configuration one, lower swing arm and drag link equal length, and from terms of rearview during configured in parallel, with wheel
Lower motion toe-in angle is not changed in；In configuration two, lower swing arm and drag link equal length, and the non-parallel configuration from terms of rearview
When, as wheel up and down motion toe-in angle changes；In configuration three, lower swing arm and drag link configured in parallel, and length is unequal
When, as wheel up and down motion toe-in angle changes.
As can be seen here, when lower swing arm and drag link equal length and the configured in parallel from terms of rearview, independent suspension
The interference control to steering system is moved to Min., is perfect condition.But, for various reasons, Car design or reality
With in, not using this desired configuration state.
In the mechanism of independent suspension, if a connector there are three tie points, cry " arm ", or cry swing arm, and only have
, " connecting rod ", modern suspension is more and more using bar linkage structure for the connector of two tie points, especially adopts high-grade suspension more
Use wrought aluminium connecting rod.
The more and more employing independent suspensions of front suspension of passenger car or commercial car, as front suspension is combined with steering
Together, rotary shaft 09 is formed by ball pin, on the outside of the connector below the front suspension of prior art, adopts the company of a ball pin
On the inside of contact for two bush structures as tie point, this connector is usually swing arm structure, as shown in Fig. 2 be McPherson
Independent suspension and steering mechanism, including damper 01, right turn section 02, ball pin assembly 03, stabilizer bar connecting bar 04, helical spring
05th, bottom right swing arm 06, taper pad 07 and subframe 08.
As outer tie point 010 is different with the drag link length of steering from the distance of interior tie point 012, or connect outward
Contact 010 is not parallel with the line of interior tie point 012 and the drag link of steering, according to Fig. 1, existing lower swing arm knot
Structure, motion and the steering movement interference of the lower swing arm of independent suspension, not only accelerates wheel wear, and affects vehicle row
Sail stability.
