Description
Technical field
The utility model relates to automotive field, particularly, relates to a kind of leaf spring for vehicle suspension shock mitigation system, and comprises the vehicle of this leaf spring.
Background technique
Leaf spring is widely used in vehicle suspension shock mitigation system, is used for connecting vehicle frame and vehicle bridge, bears and transmitted load, and cushions road shocks.The raising required along with car load NVH and the light-weighted demand of car load, weight and the shock-absorbing capacity of leaf spring come into one's own.In prior art, leaf spring generally comprises the multiple leaves of spring be superimposed together.But, because leaf of spring only has rigidity, undamped performance, and density of material is comparatively large, leaf spring overall weight therefore can be made comparatively large, and only can play elastic buffer effect, cannot absorb vibration better, affect car load travelling comfort.
Model utility content
An object of the present utility model is to provide a kind of leaf spring, and this leaf spring can reduce weight, and can absorb vibration, improves car load travelling comfort.
Another object of the present utility model is to provide a kind of vehicle, the leaf spring that this vehicle uses the utility model to provide.
To achieve these goals, according to an aspect of the present utility model, provide a kind of leaf spring, comprise the multiple spring sheets be superimposed together, described multiple spring sheet comprises composite spring piece and leaf of spring.
Preferably, in described multiple spring sheet, the superiors and undermost spring sheet are leaf of spring.
Preferably, the spring sheet in described multiple spring sheet between the superiors and orlop is composite spring piece.
Preferably, in described multiple spring sheet, composite spring piece and leaf of spring interlock stacked.
Preferably, described multiple spring sheet is linked together by centre bolt.
Preferably, in described multiple spring sheet, the spring sheet of the superiors is linked together by spring clip with spring sheet at least partially.
According to another aspect of the present utility model, provide a kind of vehicle, described vehicle comprises the leaf spring that the utility model provides.
Pass through technique scheme, owing to having the structural type that composite spring piece combines with leaf of spring, the leaf spring that the utility model provides can realize the reduction of leaf spring overall weight, utilize the damping characteristic of composite material itself simultaneously, can vibrational energy be absorbed in material, thus vibration noise can be reduced to surrounding radiation, better absorb vibration, improve the travelling comfort of car load.
Other feature and advantage of the present utility model are described in detail in embodiment part subsequently.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model, but does not form restriction of the present utility model with embodiment one below.In the accompanying drawings:
Fig. 1 is the schematic perspective view of the leaf spring in a kind of mode of execution provided according to the utility model.
Description of reference numerals

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
In the utility model, when not doing contrary explanation, the noun of locality used in all figure such as " upper and lower " is the page for accompanying drawing, if " inside and outside " is in corresponding part profile for accompanying drawing and outer.
As shown in Figure 1, according to a kind of vehicle that embodiment there is provided a kind of leaf spring and use this leaf spring of the present utility model, particularly, the leaf spring that the utility model provides comprises the multiple spring sheets be superimposed together, and the plurality of spring sheet comprises composite spring piece 1 and leaf of spring 2.
In technique scheme, by using some composite spring pieces 1 in multiple spring sheet, the leaf spring overall weight that the utility model provides is comparatively light, and the cushioning ability of leaf spring is improved simultaneously, can effectively relax and suppress road shocks.
It should be noted that, the mode of execution that can realize technique scheme has multiple, the concrete superimposed order and composition form etc. of such as composite spring piece 1 and leaf of spring 2, therefore, the utility model for convenience of description, introduce preferred implementation wherein at this, this preferred implementation, only for illustration of the utility model, is not limited to the utility model.
Particularly, in order to ensure that leaf spring bears and conducts the intensity needed for load, preferably, in the plurality of spring sheet, the superiors and undermost spring sheet are leaf of spring 2.Wherein, the leaf of spring being positioned at the superiors can be connected with vehicle frame, and being positioned at undermost leaf of spring can be connected with vehicle bridge.Material due to leaf of spring is spring steel, the tension that the leaf of spring therefore retained has and anti-compression property, can be good at ensureing the requirement of strength in dynamic changes process.
Reduce leaf spring overall weight to reach, improve the object of leaf spring cushioning ability, preferably, the spring sheet in the plurality of spring sheet between the superiors and orlop is composite spring piece 1 simultaneously.Wherein, composite spring piece has that quality is light, intensity is high, elasticity is excellent, have the composite material of the characteristics such as damping, can reduce leaf spring overall weight, better vibrational energy be absorbed in material, thus can reduce the radiation of vibration noise to surrounding.Such as, composite material can adopt carbon fibre material, glass fiber compound material etc.
In order to the relation between the intensity of further balance plate spring, quality and cushioning ability, preferably, in the plurality of spring sheet, composite spring piece 1 and leaf of spring 2 interlock stacked.Like this, both ensure that leaf spring bore and conducts the intensity needed for load, and alleviated the overall weight of leaf spring simultaneously, composite spring piece and leaf of spring interlock stacked form, also better can realize the absorption vibrated.
In order to ensure the relative position between composite spring piece 1 and leaf of spring 2, the multiple spring sheets be superimposed together are linked together by centre bolt 3.That is, by centre bolt running through multiple spring sheet, the relative fixing of composite spring piece and leaf of spring is realized.
In order to connect composite spring piece 1 and leaf of spring 2 better, preferably, in the plurality of spring sheet, the spring sheet of the superiors is linked together by spring clip 4 with spring sheet at least partially.It should be noted that, " at least partially spring sheet " comprises at least two panels composite spring piece or stacked composite spring piece and leaf of spring.Like this, the annexation in the spring clip connection reinforcement that distance center bolt is far away leaf spring between each spring sheet, thus make leaf spring entirety more stable.
To sum up, the utility model provides a kind of leaf spring of damping lightweight, wherein leaf of spring 2 tension, anti-compression property ensure that leaf spring bears and conducts the intensity needed for load, simultaneously composite spring piece 1 lightweight, flexible and have the feature of damping, leaf spring overall weight can be reduced, improve the cushioning ability of leaf spring, car load travelling comfort is improved.
Below preferred implementation of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition, each the concrete technical characteristics described in above-mentioned embodiment, in reconcilable situation, can be combined by any suitable mode.In order to avoid unnecessary repetition, the utility model illustrates no longer separately to various possible compound mode.
