Description
Technical field
The invention belongs to suspension technical fields, particularly relate to a kind of type front independent suspension mechanism.
Background technique
Automotive suspension is the important component for guaranteeing riding comfort, meanwhile, automotive suspension is as vehicle body (or vehicle frame) and vehicle
Make the force transferring part connected between axis (or wheel), and is the important component for guaranteeing ride safety of automobile.
Independent suspension is that the wheel of left and right two on an axle by automobile is individually installed on vehicle body (or vehicle frame)
Under, vehicle bridge uses breakaway-element, and intermediate one section is fixed on vehicle body (or vehicle frame), mutual not shadow when two sidecar wheel of independent suspension is hit
It rings, and since the sprung mass is relatively light, buffering is very strong with damping capacity, riding comfort is good, and indices are better than non-only
Vertical suspension, but independent suspension structure is complicated.
Present vehicle four-wheel alignment is fewer, mainly front-axle steering, and the front axle of passenger car mostly uses independent suspension, 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 influences steering structure very big, as shown in Figure 1 in three kinds of configurations, upper figure is front suspension in each configuration
Top view, the following figure is rearview.
In configuration one, lower swing arm and drag link equal length, and in terms of rearview when configured in parallel, on wheel
Lower movement toe-in angle does not change；In configuration two, lower swing arm and drag link equal length, and the non-parallel configuration in 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.
It can be seen that when lower swing arm and drag link equal length and the configured in parallel in terms of rearview, independent suspension
It moves the interference to steering system to control to minimum limit, is perfect condition.But for various reasons, Car design or reality
In, this desired configuration state is not used.
In the mechanism of independent suspension, if there are three tie points for a connector, it is " arm ", or cry swing arm, and only had
For the connector of two tie points " connecting rod ", modern suspension is more and more using link mechanism, and especially high-grade suspension is adopted more
With wrought aluminium connecting rod.
Passenger car or the front suspension of commercial vehicle are more and more using independent suspension, since front suspension is combined with steering system
Together, rotary shaft 09 is formed by ball pin, the company of a ball pin is used on the outside of the connector below the front suspension of the prior art
It is two bush structures on the inside of contact as tie point, this connector is usually swing arm structure, as shown in Fig. 2, being McPherson
Independent suspension and steering mechanism, including damper 01, right turn section 02, ball pin assembly 03, stabilizer bar connecting bar 04, helical spring
05, bottom right swing arm 06, taper gasket 07 and subframe 08.
Due to outer tie point 010 at a distance from interior tie point 012 and the drag link length of steering system is different, or connect outside
Contact 010 and the line of interior tie point 012 and the drag link of steering system are not parallel, as can be seen from FIG. 1, existing lower swing arm knot
Structure, the movement of the lower swing arm of independent suspension and steering system movement interference, not only accelerate wheel wear, but also influence vehicle row
Sail stability.
