Description

Seat and comprise its vibration damper under absorber spring

Technical field

The utility model relates to vibration damper field, particularly seat and comprise its vibration damper under a kind of absorber spring.

Background technique

Concussion when vibration damper rebounds after being mainly used to suppress spring shock-absorbing and the impact from road surface.Through uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is just used to suppress this spring to jump.

Fig. 1 is the sectional view of traditional shock absorber spring lower seat.Fig. 2 is the sectional arrangement drawing of traditional shock absorber spring lower seat.As depicted in figs. 1 and 2, traditional Mai Fuxun vibration damper generally adopts steel plate punched spring lower seat 10, and is furnished with the object that spring vibration isolation pad 20 realizes noise abatement vibration isolation.The spring lower seat 10 of this vibration damper is that the unitary metallic that volume is larger strikes out shaped piece, and spring lower seat 10 is connected with vibration damper urceolus 30, and spring vibration isolation pad 20 is arranged on spring lower seat 10.

But the vibration damper heavier-weight of this structure, structure is comparatively complicated, and vibration isolator cost is higher simultaneously.

Model utility content

The technical problems to be solved in the utility model is to overcome traditional shock absorber heavier-weight in prior art, and baroque defect, provides seat under a kind of absorber spring and comprises its vibration damper.

The utility model solves above-mentioned technical problem by following technical proposals: seat under a kind of absorber spring, its feature is, under described absorber spring, seat comprises spring lower seat support and spring lower seat enclosure, described spring lower seat supports and adopts metalwork to make, and the middle indent that described spring lower seat supports, both sides stretch out, the surface that the coated described spring lower seat of described spring lower seat enclosure supports.

Preferably, the shape that described spring lower seat supports is mated with corresponding spring.

Preferably, the thickness that described spring lower seat supports is 2-4mm.

Preferably, described spring lower seat enclosure adopts engineering plastics to make.

Preferably, described spring lower seat enclosure direct and described spring lower seat support and connection by injection moulding.

Preferably, the thickness of described spring lower seat enclosure is 1-2mm.

The utility model additionally provides a kind of vibration damper, and its feature is, it comprises seat and vibration damper urceolus under absorber spring as above, and under described absorber spring, seat is connected with described vibration damper urceolus.

Preferably, under described absorber spring, seat is connected with described vibration damper urceolus by welding or press-fiting.

Positive progressive effect of the present utility model is: the lighter in weight of seat under the utility model absorber spring, and structure is comparatively simple, reduces the cost of vibration damper simultaneously.Described vibration damper is the design optimization based on lightweight scheme, by integrated spring lower seat and vibration isolator, and uses lightweighting materials, improves the anti-vibration performance of spring seat, reduces weight and the cost of shock absorber strut.

Accompanying drawing explanation

The above and other feature of the utility model, character and advantage are by more obvious by what become below in conjunction with the description of drawings and Examples, and reference character identical in the accompanying drawings represents identical feature all the time, wherein:

Fig. 1 is the sectional view of traditional shock absorber spring lower seat.

Fig. 2 is the sectional arrangement drawing of traditional shock absorber spring lower seat.

Fig. 3 is the sectional view of seat under the utility model absorber spring.

Fig. 4 is the sectional arrangement drawing of seat under the utility model absorber spring.

Embodiment

For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.

Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, therefore the utility model is not by the restriction of following public specific embodiment.

Fig. 3 is the sectional view of seat under the utility model absorber spring.Fig. 4 is the sectional arrangement drawing of seat under the utility model absorber spring.

As shown in Figure 3 and Figure 4, disclose seat 40 under a kind of absorber spring in an embodiment of the present utility model, it comprises spring lower seat and supports 41 and spring lower seat enclosure 42.Wherein, spring lower seat supports 41 and adopts metalwork to make, and spring lower seat supports the middle indent of 41, and both sides stretch out.The coated spring lower seat of spring lower seat enclosure 42 supports the surface of 41.

Herein, the shape of spring lower seat support 41 is mated with corresponding spring.Preferably, the thickness of spring lower seat support 41 is 2-4mm, and its thickness and size are determined by the actual load of be suitable for vehicle spring usually certainly, are not limited to above-mentioned citing.

Spring lower seat enclosure 42 is owing to mainly shielding, and its bearing load is less, therefore adopts engineering plastics to make, and spring lower seat enclosure 42 directly supports 41 with spring lower seat by injection moulding and is connected, and covers spring lower seat stayed surface.The thickness of spring lower seat enclosure 42 is preferably 1-2mm.Due to spring lower seat enclosure 42 have employed non-metallic material after there is good vibration isolation function, therefore can cancel the vibration isolator in traditional design, thus vibration damper cost can be reduced.

In addition, the utility model additionally provides a kind of vibration damper, and it comprises seat 40 and vibration damper urceolus 30 under absorber spring as above, and under absorber spring, seat 40 is connected with vibration damper urceolus 30.Further, under absorber spring, seat 40 is connected with vibration damper urceolus 30 by welding or press-fiting.

In the utility model, spring lower seat supports 41 owing to will bear larger load, and preferably adopt metal material, such as steel plate punched is shaping, but its volume comparatively traditional design greatly reduce.In vibration damper of the present utility model, spring lower seat is supported 41 to be connected with vibration damper urceolus 30.

In sum, the utility model, in order to alleviate the weight of vibration damper, reduces vibration damper cost, and ensure support and the anti-vibration performance of vibration damper, according to functional requirement, spring lower seat is subdivided into further spring lower seat and supports and spring lower seat encirclement, and select different materials respectively to realize.

Described vibration damper lighter in weight, structure is comparatively simple, reduces the cost of vibration damper simultaneously.This vibration damper is the design optimization based on lightweight scheme, by integrated spring lower seat and vibration isolator, and uses lightweighting materials, improves the anti-vibration performance of spring seat, reduces weight and the cost of shock absorber strut.Such design optimization has market prospects widely.

Although the foregoing describe embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these mode of executions, but these change and amendment all falls into protection domain of the present utility model.
