Abstract

The utility model discloses a vehicle damping spring, as one vehicle damping combined spring, characterized in that at least one torsion spring is serially connected integrally, and the outer arm of each torsion spring is extended to the spring core of another torsion spring to be connected. When the outer torsion spring bears force, first the torsion spring reduces and deforms, to transmit force to next connected torsion spring, the combined spring releases accumulated elastic force gradually, therefore, the utility model has damping property. And the utility model uses the torsion spring with low cost, to reduce the whole cost.

Description

Automobile-used damping cluster spring

The utility model discloses a kind of automobile damping spring.

At present, existing automobile mainly is spiral stage clip with damping spring, along with ground-surface changes, spiral stage clip is subjected to force compresses, resist the vibrations that car body produces with road bump by the elastic force of accumulating after its compression, above-mentioned vibrations are big more, and the elastic force of accumulating is also just big more, thereby it is strong to make the driver and crew of vehicle feel more vibrations; For avoiding automobile above-mentioned serious seismism to occur, the complex structure of the shock absorption device setting of some automobile and involving great expense is selected hydraulic pressure and pneumatic type shock absorption device for use as some high-grade car, though it has good shock-absorbing function, its price is high.

The purpose of this utility model provides the automobile-used damping cluster spring that a kind of cost is low, elasticity is soft and bounce is little.

For achieving the above object, the technical solution adopted in the utility model is: automobile-used damping cluster spring is characterized in that: more than one torque spring is one another in series and is one.

As shown from the above technical solution, the outer arm of each torsion spring extends the spring core place of another torsion spring and is connected to each other, like this when exterior torsion spring is stressed, it at first is this torsion spring shrinkage distortion, then power is passed to coupled next torsion spring, carry out the transmission of power thus, in the process of power transmission, little by little vibration is cut at last minimum, the elastic force that cluster spring discharges savings in it also progressively discharges, thereby the utlity model has the advantage of damping, because the utility model adopts the comparatively cheap torsion spring of cost, its cost advantage is also fairly obvious in addition.

Description of drawings

Fig. 1 is a perspective view of the present utility model;

Fig. 2 is that member of the present utility model is installed decomposing schematic representation.

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment

As shown in Figure 1, more than one

torque spring

10,20,30,40 etc. is one another in series and is one, and link into an integrated entity its shape of back such as V-shape launch relatively.

Be provided with the rod member 50 of a shape in the spring health of above-mentioned torque spring 10, its end is connected with the end 24 that the outer arm 22 of adjacent torsion spring 20 curves ring-type,

torque spring

10,20,30,40 constitutes the series connection of radial type each other, so that

torque spring

10,20,30,40 is connected between the

rod member

50,60 and can rotates mutually with it, help the stress deformation of torque spring like this.As shown in Figure 2, the outer arm 22 of the spring health of torque spring 10 and adjacent torque spring 10 curves end 24 consistencies from top to bottom of ring-type during assembling, and rod member 50 therefrom inserts, and its two ends can add black nut and pad; All the other adjacent torque springs 20,30,40 are connected with reference to above-mentioned mode and rod member 60 etc., constitute cluster spring thus.

The utility model is not limited to the described content of the foregoing description, be that the combinations thereof spring at first is to turn to several independently torque springs with some short spring wires, again they are chained together each other, the utility model can also be with being shaped with long spring wire coiling, and can omit the above-mentioned rod member that is used for bonded assembly axle shape this moment.

Claims

1. automobile-used damping cluster spring, it is characterized in that: more than one torque spring is one another in series and is one.

2. automobile-used damping cluster spring according to claim 1, it is characterized in that: the rod member that is provided with a shape in the spring health of above-mentioned torque spring, its end is connected with the end that the outer arm of adjacent torsion spring curves ring-type, and torque spring constitutes the series connection of radial type each other.
