Abstract
The utility model discloses a damping spring. The damping spring comprises a cylinder, soft spring steel columns, hard spring steel columns, soft springs, and hard springs, wherein the soft spring steel columns are arranged on two sides of the cylinder; the hard spring steel columns are fixedly connected with pistons at two ends of the cylinder respectively; the soft spring steel columns and the hard spring steel columns drive the two pistons in the cylinder when moving; the soft springs and the hard springs are sleeved on the soft spring steel columns and the hard spring steel columns respectively; one end of each soft spring is foxed with the cylinder, and the other end of each soft spring is fixed outside each soft spring steel column; and one end of each hard spring is fixed with the cylinder, and the other end of the hard spring is fixed outside each hard spring steel column. The damping spring can realize damping during mild bumping by using the soft springs, can provide effective support for strong bumping by using the elasticity of the hard springs, and has more obvious damping effect than single damping springs. The damping spring can meet the requirements on comfortableness and moveability when used for vehicles such as automobiles and the like, has low cost and long service life and can be popularized and applied to various vehicles.
Description
Technical field
The utility model relates to a kind of damping device, is specifically related to a kind of damping spring that is applied in the traffic tool such as automobile.
Background technique
In the prior art, used damping spring to reduce automobile jolting in the process of moving on the automobile in a large number, but generally all use a spring in the automobile to reach the purpose of damping, general spring often can not bear comparatively strong jolting, damping effect is not obvious, and single spring causes reducing elasticity at the long-time back degree of wear height that uses, damage or the fracture back if can not on-call maintenance, change and be easy to bury potential safety hazard.
A kind of prior art is used for the helical spring of damping, under free state, a spring wherein plane, inactive coil place and plane, the other end spring coil place is an angle, angular range is 15 °-25 °, and subpoint (O ↓ [1] in the plane, arbitrary therein inactive coil place, the center of two inactive coils, O ↓ [2]) have skew, offset ranges is 20-50mm.The helical spring of this kind damping adopts single spring, and shock resistance is poor, and higher to the making required precision of spring, and cost is also higher relatively.
In view of the above problems, the utility model discloses a kind of damping spring.It has technical characteristics as mentioned below, to solve existing problem.
Summary of the invention
The purpose of this utility model provides a kind of damping spring, and it is applicable in the automobile shock-absorber, can play the effect of damping when automobile is subjected to jolting, and can resist stronger vibrations, increases the comfort level of automobile when not influencing motor racing.
The purpose of the utility model damping spring is achieved through the following technical solutions: a kind of damping spring, it is characterized in that: comprise cylinder and be arranged on soft spring steel column, the hard spring steel column of described cylinder both sides, described soft spring steel column and hard spring steel column are fixedlyed connected with the piston at described cylinder two ends respectively, and described soft spring steel column and hard spring steel column drive two-piston in the described cylinder when moving.
Also comprise the soft spring and the hard spring that are nested with respectively on described soft spring steel column and hard spring steel column, one end of described soft spring is fixed on the described cylinder, the other end is fixed on the outer end of described soft spring steel column, one end of described hard spring is fixed on the described cylinder, and the other end is fixed on the outer end of described hard spring steel column.
Above-mentioned damping spring, wherein, the elasticity coefficient of described hard spring is greater than the elasticity coefficient of described soft spring.
The utility model damping spring makes it compared with prior art owing to adopted such scheme, has following advantage and good effect:
Damping when 1, the utility model damping spring is realized slightly jolting by soft spring, utilize the elastic force of hard spring to provide effective support simultaneously to jolting more by force, more single relatively damping spring damping effect is obvious, be applied on the traffic tool such as automobile and can satisfy travelling comfort, can satisfy motility again.
2, the utility model damping spring is owing to adopted simple cluster spring to reach damping effect preferably, with low cost, the friction between soft spring and the hard spring has been avoided in the use of cylinder, makes this device that be arranged long working life, can apply in the various traffic tool.
Below; to be described further by specific embodiment; yet embodiment only is giving an example of the optional mode of execution of the utility model, and its disclosed feature only is used for explanation and sets forth the technical solution of the utility model, and is not used in qualification protection domain of the present utility model.
Description of drawings
Fig. 1 is the structural representation of the utility model damping spring.
Embodiment
It below is the concrete technological scheme of the utility model damping spring.
See also shown in the accompanying drawing 1, the utility model damping spring comprises cylinder 01 and is arranged on the soft spring steel column 02 of cylinder 01 both sides, hard spring steel column 03, soft spring steel column 02, hard spring steel column 03 are fixedlyed connected with the piston at cylinder 01 two ends respectively, soft spring steel column 02, drive cylinder 01 interior two-piston when hard spring steel column 03 moves; Also comprise the soft spring 04 and the hard spring 05 that are nested with respectively on soft spring steel column 02, hard spring steel column 03, one end of soft spring 04 is fixed on the cylinder 01, the other end is fixed on the outer end of soft spring steel column 02, one end of hard spring 05 is fixed on the cylinder 01, and the other end is fixed on the outer end of hard spring steel column 03.And the elasticity coefficient of hard spring 05 is greater than the elasticity coefficient of soft spring 04.
The using method of the utility model damping spring is, the amalgamation of soft spring 04 and hard spring 05 realizes the routine soft spring effect of jolting, and strenuous exercise and big bump be by the intervention of hard spring 05, thereby reaches damping effect preferably.For avoiding soft spring 04 and hard spring 05 collision, the centre utilizes hydraulic pressure to realize the conversion of critical value, i.e. compression by gas in the cylinder 01 promotes soft spring steel column 02, hard spring steel column 03 to two side shiftings.Damping when soft spring 02 is used for slightly jolting, soft spring steel column 02 is by gas in the Piston Compression cylinder 01, but after arriving to a certain degree when jolting, gas is compressed to a certain degree in the cylinder 01, soft spring 04 is compressed to the limit simultaneously, and pressure pushes away to hard spring 05 direction, continues compression hard spring 05, the elastic force of hard spring 05 plays effective support, reaches the purpose of damping once more.
In sum, damping when the utility model damping spring is realized slightly jolting by soft spring, utilize the elastic force of hard spring to provide effective support simultaneously to jolting more by force, more single relatively damping spring damping effect is obvious, be applied on the traffic tool such as automobile and can satisfy travelling comfort, can satisfy motility again.The utility model damping spring is owing to adopted simple cluster spring to reach damping effect preferably, with low cost, the friction between soft spring and the hard spring has been avoided in the use of cylinder, makes this device that be arranged long working life, can apply in the various traffic tool.
Foregoing is the exemplifying of specific embodiment of the utility model damping spring, for the wherein not equipment of detailed description and structure, should be understood to take existing standard equipment in related domain and universal method to be implemented.
