Principle of the present utility model is described as follows:
1, Fig. 2, Fig. 3 are seen, the design describe described in upper and lower, front, rear, left and right as shown in Figure 2 and Figure 3, but it will be appreciated that, these directional terminology are based on position relation shown in the drawings, it is for only for ease of the locations of structures relation describing the design, rather than instruction or the hint device of indication or parts must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that restriction to the design.
2, prior art generally uses by the two stage stiffness duplex of major and minor spring parallel combination, when designing this spring, (i.e. suspension is from zero load to fully loaded various loaded-up conditions should to consider to meet the requirement of car load ride comfort, natural frequency change is the least), again in view of the requirement making major and minor spring meet static strength and fatigue life respectively.Generally design is to mate major and minor spring rigidity by fully loaded natural frequency requirement, and under sky, full load condition, the natural frequency of car load changes greatly；Vehicle is in transport semi-load, and major and minor spring all carries, and at this moment car load ride comfort is poor；The rigidity of major and minor spring meets suspension system bearing requirements, arranged with space by structure and limited, rigidity and the specific stress of main spring are bigger than normal, and auxiliary spring is shorter than main spring a lot, the leaf spring that sheet is thin, sheet number is many should not be used again, therefore its rigidity and specific stress are bigger than normal, static stress and the limit stress of result auxiliary spring are the most excessive, and the reliability of the most major and minor spring is poor.
And the design one complex stiffness suspension system uses three grades of Stiffness formulas, this suspension system includes main spring the 1, first auxiliary spring the 2, second auxiliary spring 3, described main spring the 1, first auxiliary spring 2 is all connected with the vehicle frame outside of belly 4, first auxiliary spring 2 is positioned at the surface of main spring 1, main spring the 1, first auxiliary spring 2 is connected with back axle 7 by U-bolt 6, described second auxiliary spring 3 is connected with vehicle frame lower aerofoil 5, vehicle frame lower aerofoil 5 is vertical with the vehicle frame outside of belly 4 to be connected, and described second auxiliary spring 3 is positioned at the top of back axle 7 and the second auxiliary spring 3 is positioned at the right side of main spring the 1, first auxiliary spring 2.Described main spring 1 is leaf spring, and its rigidity value is C1, described first auxiliary spring 2 is leaf spring, and its rigidity value is C2, described second auxiliary spring 3 is rubber spring, and its rigidity value is C3；When vehicle axle load is less, the most main spring 1 carries, such as, under vehicle is in Light Condition, vehicle axle load is P1, now axle load is less, and the most main spring 1 carries；When increasing to certain value along with axle load, 21, No. two auxiliary spring supports 22 of the first auxiliary spring 2 and an auxiliary spring support contact, and the first auxiliary spring 2 starts carrying, and the most main spring the 1, first auxiliary spring 2 functions both on, such as, under vehicle is in half cargo condition, vehicle axle load is P2, now provided carrying by main spring the 1, first auxiliary spring 2；When vehicle axle load reaches certain value, the second auxiliary spring 3 contacts with back axle 7, and the second auxiliary spring 3 participates in carrying, such as, under vehicle is in full load condition, vehicle axle load is P3, now jointly carried by main spring the 1, first auxiliary spring 2 and the second auxiliary spring 3.The rigidity value C of main spring 11, the rigidity value C of the first auxiliary spring 22, the rigidity value C of the second auxiliary spring 33With vehicle axle load P1、P2、P3It is all specifically to carry according to vehicle and frequency requirement matched design.Two stage stiffness suspension system relative to prior art, the design is when vehicle is in zero load, only carried by main spring 1, this main spring 1 is less than the rigidity of the main spring of prior art, when fully loaded frequency is identical, the idling frequency of the design is lower than the idling frequency of prior art, and namely ride comfort is preferable；Along with load increases to a timing, the first auxiliary spring 2 starts carrying, and when vehicle is in semi-load, main spring 1 concurs with the first auxiliary spring 2, and its rigidity is the least, and ride comfort is preferable；Load continues to increase, and the second auxiliary spring 3 is started working, and when vehicle full-load run, main spring the 1, first auxiliary spring 2 and the second auxiliary spring 3 jointly carries, and rigidity and the specific stress of main spring the 1, first auxiliary spring 2 are less, and the reliability of spring improves.Although the design only provides two kinds of arrangement forms of complex stiffness suspension system, but this can not illustrate that the design only includes both of these case, in concrete application, can be under the design of the design, demand according to reality application adjusts the first auxiliary spring, the position of the second auxiliary spring, or changes the version of the second auxiliary spring according to demand etc..
3, Fig. 2 is seen, the front end of described main spring 1 is fixed end support 11 by bearing pin and main spring and is formed axle even, the rear end of main spring 1 forms axle even by bearing pin and hanger 12, hanger 12 forms axle even by bearing pin and main spring hanger end support 13, and hanger 12 forms rotatable bearing pin with main spring hanger end support 13 and is connected.
4, main spring the 1, first auxiliary spring the 2, second auxiliary spring 3: described main spring the 1, first auxiliary spring 2 is leaf spring, leaf spring includes multiple-leaf spring and few two kinds of forms of leaf spring；The steel disc institute superposition that multiple-leaf spring is not waited by many leaf length, width is the same gets up, and each steel plate superposition of Multi-Leaf Springs is in an inverted cone, and steel plate topmost is the longest, the steel plate of bottom is the shortest, the sheet number of steel plate is relevant to the weight of supporting passenger vehicle, and steel plate is the most more thick more short, and spring stiffness is the biggest；Few leaf spring is got up by the thin thick middle in two ends, wide isometric steel disc institute superposition, the steel plate changes of section of few-leaf-spring is big, cross section from centre to two ends is gradually different, therefore rolling mill practice is more complicated, price is also expensive than multiple-leaf spring, but few leaf spring is compared with multiple-leaf spring, in the case of same stiffness (i.e. same bearer ability), few leaf spring is lighter by about about 50 than multiple-leaf spring, reduce oil consumption, add ride performance, and be point cantact between few leaf spring monolithic, decrease Relative friction and vibration, add the comfortableness taken.Described second auxiliary spring 3 is rubber spring, and rubber spring elastic modelling quantity is little, has bigger elastic deformation after stand under load, so as to absorbing shock and vibration, and can be simultaneously by multi-load.The design uses three grades of Stiffness formula suspension systems, the most main spring 1+ the first auxiliary spring 2+ the second auxiliary spring 3, specifically carry further according to vehicle and frequency requirement mates the combination of optimal flexible member, overcome a natural frequency change difficult problem in two stage stiffness compound suspension frame coupling, making car load ride comfort more preferable, the reliability of spring is higher.
