Description
Technical field
The invention belongs to automotive suspension technical field, particularly relates to a kind of McPherson suspension camber angle adjustment structure.
Background technology
McPherson suspension is one of most commonly used independent suspension of the world today, and which is mainly by helical spring, damping
Device, lower swing arm composition, most vehicles can also be equipped with horizontal stabilizer bar structure.McPherson suspension has simple structure, cost
Low, occupy space little the characteristics of；Certainly its stability is poor, also brighter the characteristics of anti-roll capability and antidive ability
Aobvious.
A kind of mutation of McPherson suspension structure is illustrated in figure 1, in the McPherson structure, helical spring 05 and shock absorber
01 is split-type design.Damper upper end 011 and 04 longeron of subframe are connected with vehicle body 03 as can be seen from Figure 1, damper
01 is connected with knuckle 06, and 06 one end of knuckle is connected with wheel hub 07, and the other end is connected with ball pin 02, ball pin 02 and lower swing arm 08
Connection, lower swing arm are fixed on subframe.
Such bindiny mechanism is achieved when wheel hub (fit a tyre) bob, drives lower swing arm bob, profit
Cushioning effect is played with helical spring, cushioning effect is played using damper.Ground transmission vehicle body is blocked so as to reach suspension
Exciting is acted on.
As shown in Figures 2 to 4, damper upper end is fixed on the connection detailed construction of the damper of prior art and knuckle
On vehicle body, lower end is connected with knuckle, is connected with wheel hub outside knuckle, and bottom is connected with ball pin, and ball pin is connected with lower swing arm again
Connect.When wheel hub bob, the flexible effect for realizing damping of damper.In McPherson suspension structure, damper upper
Equivalent to virtual stub line 09, camber angle is become based on the main virtual stub line to the line at installation center point and ball pin center 021
The value (if i.e. stub line changes, camber angle certainly changes) that changes, its concrete numerical value size be tire centerline cross section with
Fixture perpendicular to the ground is flare value, as shown in figure 5, if viewed from above, into if inverted trapezoidal, camber angle is tire
Just, if trapezoid, camber angle is negative.
In the larger light bus of bearing requirements, in order to ensure vehicle in full load, wheel can connect existing suspension application
Nearly 0 ° of camber angle, the state of 0 ° of toe-in value move ahead, and the four wheel locating parameter design principle that car load is required when unloaded is positive camber angle
Arrange in pairs or groups positive toe-in value (some cars also require that inward camber collocation toe-out).Car load four wheel locating parameter designs occurrence：Before
Beam value 0 ± 2mm of scope；0.15 ± 1 ° of flare value scope.The dispatch from the factory parameter value of control of car load is often controlled；Toe-in value 0-2mm,
In the interval range of camber angle 0-60 ', as shown in Figure 5.
Fig. 6 is to look back from right ahead, left side toe-in value for-, the right toe-in value for+；Prior art vehicle is unloaded
Toe-in of front wheel angle front-wheel state on the right of Fig. 6 during state.
The suspension system of prior art, when vehicle Light Condition, keeps the positive prenex state of positive flare coupling, works as vehicle
Full load is loaded onto, tyre toe-out and toe-in have the performance for tending to 0 degree, it is ensured that tire occurs without eccentric wear situation.
In prior art, the setting of toe-in value can be adjusted by adjusting steering gear pull bar, and the value of camber angle is only
Can be by controlling car load parts precision and assembly precision, it is ensured that when car load is reorganized and outfit, camber angle is+value, it is impossible to adjust, substantially
McPherson suspension cannot adjust camber angle at present.
In prior art, the upper end of damper is integrally fixed on the wheel bag 010 of vehicle body, and during vehicle use,
Wheel bag often occurs sinking situation (as intensity deficiency causes steel plate to be plastically deformed), so directly results in the appearance of vehicle camber angle
Negative value, and then also cause tire eccentric wear occur, concrete as shown in Figure 7.
Fig. 7 be vehicle in Light Condition because the change procedure of the sinking to camber angle of wheel bag, when all parts skills
When art state is optimum state (containing sprung parts and wheel bag part), now design point institute in outer dip angle such as schematic diagram
Show, camber angle is substantially in+40 ' left and right；When bag sinking 10mm or so is taken turns, camber angle is almost 0 °；When wheel bag sinking 20mm left sides
When right, camber angle is changed into -40 ' left and right.
Camber angle when if vehicle is unloaded becomes for 0 ° or even negative angle, so it is very easy to cause vehicle full load
There is eccentric wear problem, have a strong impact on Life of Tyre.
Content of the invention
