Abstract
The purpose of this utility model body provides a kind of suspension fork screw spring sheath, the friction abnormal sound between sheath and adjacent springs spring body can be evaded, sheath is the helix identical with helical spring and inner side is provided with opening, and convex portion is arranged on lateral wall above and/or under its sheath.Compared with prior art, contacted when helical spring compresses, during contact between sheath and adjacent spring spring body from original face and be changed into linear contact lay, relative motion occurs between sheath and adjacent springs spring body, violent change in friction force will not be produced, eliminate " " abnormal sound.
Description
Technical field
It the utility model is related to automobile suspension system field, and in particular to a kind of suspension fork screw spring sheath.
Background technology
The end of helical spring spring body on automotive suspension directly contacts with iron spring base, the adjacent spring body of interlude it
Between spacing it is equal, but the spacing between the spring spring body and spring base at both ends, in spring-compressed, the spring of end
Can be contacted with each other between spring body, produce abrasion and abnormal sound, to solve this problem, the technical scheme generally used at present for
Increase sheath in spring spring body at the top of helical spring, completely cut off between spring spring body and spring base and spring spring body and spring body it
Between contact with each other.As shown in Figure 1 and Figure 2, the outer surface of sheath 1 is relatively smooth, and sheath is general for sheath of the prior art
All be PUR materials, be that face contacts when spring is compressed, between sheath 1 and adjacent springs spring body 2, once sheath 1 with it is adjacent
Spring spring body 2 overcomes stiction under external force and relative motion occurs, and contact surface can switch to dynamic friction from static friction,
Violent change in friction force is often produced, and then send " " abnormal sound.
Utility model content
The purpose of this utility model body provides a kind of suspension fork screw spring sheath, can evade sheath and adjacent springs spring body
Between friction abnormal sound.
To achieve these goals, the technical solution adopted in the utility model is：A kind of suspension fork screw spring sheath, sheath
Helix and inner side to be coincide with helical spring are provided with opening, and convex portion is arranged on lateral wall above and/or under its sheath.
Compared with prior art, when helical spring compresses, during contact between sheath and adjacent spring spring body by
Face contact originally is changed into linear contact lay, and relative motion occurs between sheath and adjacent springs spring body, will not produce violent friction
Power change, eliminate " " abnormal sound.

Fig. 2 is sheath in the prior art and helical spring cooperation schematic diagram；
Fig. 3 is the structural representation of sheath body in the utility model；
Fig. 4 is sheath body and helical spring cooperation schematic diagram in the utility model.
Embodiment
As shown in Figure 3, Figure 4, a kind of suspension fork screw spring sheath, sheath 10 be with helical spring coincide helix and
Inner side is provided with opening 11, arranges convex portion 12 above and/or under sheath 10 on lateral wall.First at the interior side opening 11 of sheath 10
Sheath 10 is enclosed in the spring body of helical spring, when helical spring compresses, connecing between sheath 10 and adjacent spring spring body
Linear contact lay is changed into from original face contact when touching property, relative motion occurs between sheath 10 and adjacent springs spring body, will not produce
Violent change in friction force, eliminate " " abnormal sound.
Further, described convex portion 12 is along the length direction arranged for interval of sheath 10.So sheath 10 when being squeezed,
Uniform force, improve the service life of sheath 10.
Preferably, described convex portion 12 be rib strip shaped its along the outer wall of sheath 10 circumferentially.
Enter due to might have water during use inside sheath 10, wall above and/or under described sheath 10
On open up insertion inner tubal wall through hole 13.So when helical spring forced compression, sheath 10 can also compress, and water can is from passing through
Logical through hole 13 flows out, and ensures the drying property inside sheath 10.
In order to prevent the spring body of sheath 10 and spring from relative displacement, inner surface and the helical spring outer surface of sheath 10 occurs
Between for interference fit.The ground inner surface of sheath 10, to ensure that relative displacement does not occur in the two, can prevent sheath 10 at it with gluing
It is squeezed to crush on length direction and splits, improves the service life of sheath 10.
Further, one end of sheath 10 and/or both ends end set have a locating piece 14, above and/or under locating piece 14
Also lug boss 141 is arranged on lateral wall, and the external diameter of lug boss 141 is identical with the external diameter of convex portion 12.By the external diameter of lug boss 141
It is designed to identical with the external diameter of convex portion 12, when can thus avoid the helical spring from compressing, locating piece 14 touches adjacent springs
Spring body and convex portion 12 are also not in contact with the phenomenon generation to adjacent springs spring body, while the effect of lug boss 141 and the work of convex portion 12
With identical.
