Description
Technical field
The present invention relates to the serial assembly of spring for motor car, and in particular to a kind of light-weighted plate spring structure of variation rigidity.
Background technology
When load change is larger, such as automobile is unloaded, fully loaded, if automobile is using conventional linear elasticity leaf spring, it is difficult to ensure that automobile can obtain good ride comfort under various load, therefore when plate spring suspension brackets are designed, frequently with the compound leaf spring of two stage stiffness or leaf spring with gradually changing stiffness, nonlinear characteristic is obtained.
The A of patent CN 104696403 disclose a kind of offset frequencys such as variation rigidity and are combined spring structure, possess preferable variation rigidity characteristic.But the plate spring structure of this structure divides main spring and auxiliary spring, structure is complex.
The content of the invention
The present invention reduces the weight of suspension, reaches light-weighted purpose in order to be able to reduce the complexity of flat spring structure;So that automotive light weight technology reduces fuel consumption, its pollution to environment is reduced, spy proposes a kind of flat spring structure of variation rigidity.
The technical scheme is that, a kind of flat spring structure of variation rigidity, including a piece of total length reed, described total length reed one end is bent upwards provided with grasswort one, and the other end is bent upwards or is bent downwardly, and is provided with cushion pad on an opposite end;The centre of total length reed is flat segments one, and flat segments one are provided with centre bolt hole, and are fixed with a piece of half long reed by centre bolt and nut, and one end of half long reed is flat segments two, and the other end is bent upwards provided with grasswort two;Wherein flat segments one are crossed centre bolt with flat segments two-way and are fixedly connected with nut.
Further improve is:Described total length reed forms variable section structure from middle flat segments one to two ends.
Further improve is:Half described long reed is the variable section structure being bent upwards.
Further improve is:Pad is provided between the flat segments two of the long reed of flat segments one and half of total length reed.
Beneficial effect:
Total length reed and half long reed are merged in the present invention, main spring and auxiliary spring is formed, flat spring structure simple in construction is formed, not only possesses the characteristic of variation rigidity, and alleviates plate spring assembly quality, lightweight is realized.
The present invention not only can effectively reduce structural complexity, and can reduce the weight of suspension, reach light-weighted purpose;And automotive light weight technology can reduce fuel consumption, its pollution to environment is reduced, is to save one of effective approach of the energy, is also the important goal that international advanced automobile enterprise is pursued.
The variation rigidity flat spring structure of the present invention, main spring and auxiliary spring is merged, using reed of the two panels with grasswort, in zero load, only arrangement works of ear-rolling end, after load increase, the grasswort two of half long reed is contacted with the buffer stopper of the non-ear-rolling end of total length reed, realizes the characteristic of stiffness variation;The wherein non-ear-rolling end of total length reed is bent upwards, and plate spring assembly can realize two stage stiffness characteristic, and be bent downwardly, and plate spring assembly can realize variation rigidity characteristic;And its is simple in construction, the grasswort structure of two reeds is separate, can prevent the crooked influence to leaf spring entrucking of grasswort.
Brief description of the drawings
Fig. 1 is embodiments of the invention one.
Fig. 2 is embodiments of the invention two.
1 is half long reed, and 2 be pad, and 3 be total length reed, and 4 be centre bolt, and 5 be center nut, and 6 be buffer stopper.7 be grasswort one, and 8 be grasswort two, and 9 be flat segments one, and 10 be flat segments two.
Embodiment
The present invention is as shown in Fig. 1/2.
Embodiment one and embodiment two are respectively the structural representation of variation rigidity flat spring in a free state.
As depicted in figs. 1 and 2, a kind of variation rigidity flat spring structure, it includes half long reed 1, pad 2, total length reed 3, centre bolt 4, center nut 5 and buffer stopper 6;Half long reed 1 and total length reed 3, which has on a straight segment structure, straight segment structure, bolt hole, is linked together by centre bolt 4, center nut 5;Pad 2 is located between half long reed 1 and total length reed 3, can prevent the directly contact of half long reed 1 and total length reed 3, the tired risk of reduction contact stress;Buffer stopper 6 is located at the non-ear-rolling end of total length reed 3, and the vibration that half long reed 1 and total length reed 3 of buffering is produced when working simultaneously reduces noise.
Flat spring assembly shown in Fig. 1, the non-ear-rolling end of total length reed 3 is bent upwards, and possesses two stage stiffness characteristic;Flat spring assembly shown in Fig. 2, the non-ear-rolling end of total length reed 3 is bent downwardly, and is possessed and is realized variation rigidity characteristic.In zero load, only arrangement works of grasswort 1, after load increase, the grasswort 28 of half long reed 1 is contacted with the buffer stopper 6 of the non-ear-rolling end of total length reed 3, realizes the characteristic of stiffness variation.
A kind of flat spring structure of variation rigidity, including a piece of total length reed 3, described one end of total length reed 3 are bent upwards provided with grasswort 1, and the other end is bent upwards or is bent downwardly, and are provided with cushion pad 6 on an opposite end;The centre of total length reed 3 is flat segments 1, and flat segments 1 are provided with centre bolt hole, and are fixed with a piece of half long reed 1 by centre bolt 4 and nut 5, and one end of half long reed 1 is flat segments 2 10, and the other end is bent upwards provided with grasswort 28;Wherein flat segments 1 are fixedly connected with flat segments 2 10 by centre bolt 4 with nut 5.
Total length reed 3 forms variable section structure from middle flat segments 1 to two ends.
Half long reed 1 is the variable section structure being bent upwards.
Pad 2 is provided between the flat segments 2 10 of the long reed 1 of flat segments one 9 and half of total length reed 3.
The advantage of the flat spring structure of above example description is as follows:
1. the warp architecture of the non-ear-rolling end by changing total length reed 3, it is possible to realize two kinds of different elastic characteristics;
2. because the grasswort structure of two reeds is separate, the influence of the crooked leaf spring entrucking inconvenience brought of grasswort can be not only reduced, and the changing of the relative positions will not occur for leaf spring in use, so eliminating leaf spring yoke configurations, further simplify flat spring structure;
3. two reeds can both be prepared using spring steel material, it can also be prepared using composite, wherein a piece of length of spring leaf is long for half, reduce the quality of plate spring assembly, realize lightweight target.
