Abstract
The utility model relates to automobile shock part field, is specifically related to a kind ofly eliminate the device that variable stiffness coil spring knocks abnormal sound.Variable stiffness coil spring circle wraps up spring housing.Spring housing is that polyurethane material makes.The beneficial effects of the utility model are: completely eliminate spring and knock abnormal sound problem, improve the travelling comfort of automobile.
Description
Technical field
The utility model relates to automobile shock part field, is specifically related to a kind ofly eliminate the device that variable stiffness coil spring knocks abnormal sound.
Background technique
The control stability of automobile and travelling comfort are two indexs that people compare concern.Affect suspension control stability and have elastic component and damping member with the element of travelling comfort, and helical spring is exactly the elastic element worked.Helical spring not consumed energy itself, the spring storing potential energy will return to the original form, and potential energy is become kinetic energy again.If be used alone spring and do not have weakening element, some light-duty vehicles will be jumped as acrobat " spring trampoline ", continuously move up and down after being subject to one-shot.Current stage helical spring major part is Line stiffness, ensures control stability again to improve travelling comfort thus devises variable stiffness coil spring.Present stage variable stiffness coil spring be designed to modified line footpath reach, but there will be circle when compressing at wire diameter segment to knock with circle and produces abnormal sound problem, so solve abnormal sound to become the most important thing that variable rate spring designs.
Model utility content
The purpose of this utility model is to solve the problem, and provides a kind of and eliminates the device that variable stiffness coil spring knocks abnormal sound.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
Eliminate the device that variable stiffness coil spring knocks abnormal sound, variable stiffness coil spring circle wraps up spring housing.
Spring housing is that polyurethane material makes.
The beneficial effects of the utility model are: completely eliminate spring and knock abnormal sound problem, improve the travelling comfort of automobile.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation,
Fig. 2 is that the utility model is arranged on schematic diagram on variable stiffness coil spring.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Embodiment: see Fig. 1, Fig. 2.
Eliminate the device that variable stiffness coil spring knocks abnormal sound, variable stiffness coil spring circle wraps up spring housing.
Spring housing is that polyurethane material makes.
Its working principle is: utilize high temperature resistant, wear resistance, the noise free of polyurethane, nonpoisonous and tasteless with, draw and do not injure the characteristics such as the life-span is long, be designed to a cover and be arranged on variable rate spring circle and circle contact area, avoid the circle of spring and the contact of circle to produce abnormal sound.
One of preferred embodiment that what embodiment of the present utility model announced is also; but be not limited thereto; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and change, but only otherwise depart from spirit of the present utility model, all in protection domain of the present utility model.
Claims (2)
1. eliminate the device that variable stiffness coil spring knocks abnormal sound, it is characterized in that: on variable stiffness coil spring circle, wrap up spring housing.
2. according to claim 1ly a kind ofly eliminate the device that variable stiffness coil spring knocks abnormal sound, it is characterized in that: spring housing is that polyurethane material makes.
