Description
Technical field
The utility model is related to a kind of limiting devices, specifically, the utility model is related to a kind of suspensions of Vehicle De L'Avant Blinde By Creussot
Reduce the limited block of twisted seat degree of freedom on helical spring in system.
Background technology
Automotive suspension is the total of all force transmission connections between vehicle frame (or monocoque body) and vehicle bridge (or wheel)
Claim.The main function of suspension is road surface to be acted on vertical reaction (supporting force) on wheel, longitudinal counter-force (driving force and braking
Power) and lateral reaction and these counter-forces be formed by torque and be transmitted on vehicle frame (or monocoque body), to ensure automobile
Normally travel.
Suspension is mainly by elastic element, guider and damping element（Damper）Etc. three parts composition.
Elastic element makes to contact as elasticity between vehicle frame and vehicle bridge, bears and transmit vertical load, mitigates and inhibits uneven
Impact caused by road surface；Guider is and to ensure wheel relative to vehicle frame for transmitting longitudinal force, lateral force and its torque
Or vehicle body has certain characteristics of motion；Damper limits the vibration of vehicle body and wheel to accelerate the decaying of vibration.Thus may be used
See, above three component part plays buffering, guiding and damping effect respectively, and triple combination plays the role of common power transmission.It is anti-
Only when uneven road surface travels or turns to excessive lateral inclination occurs for vehicle body, and partial automobile is also equipped with auxiliary elastic element-cross
To stabilizer and balancing pole.
The elastic element used in common automobile suspension system mainly has leaf spring, helical spring, torsion-bar spring, sky
Several structure types such as gas spring and rubber spring.
Helical spring is widely used in independent suspension, especially front wheel independent suspension.However, in the trailing wheel of some cars
In rigid axle suspension, elastic element also uses helical spring.Helical spring compares with leaf spring and has the following advantages：Nothing
It needs to lubricate, it is little not to avoid longitudinally mounted space of the dirt needed for it；The quality of spring itself is small.Helical spring itself is without damping
Effect, therefore damper must be separately filled in spiral spring suspension.In addition, helical spring can only bear vertical load, thus it is necessary
Guiding mechanism is installed to transmit various power and the torque other than vertical force.Helical spring is formed by spring steel bar material volume system, can be done
At uniform pitch or varying pitch.The former rigidity is constant, and the latter's rigidity is variable.
Gas spring is to be filled with compressed gas in the container sealed at one, its spring is realized using the compressibility of gas
Effect.The rigidity of this spring is variable because when acting on the load increase on spring, quantitative gas in container by
Compression, air pressure increase, then the rigidity of spring increases；Conversely, when load decreases, the air pressure in spring declines, and rigidity reduces, therefore
It has more satisfactory variation rigidity characteristic.Gas spring has two kinds of air spring and hydro-pneumatic spring.Air spring has bellows again
With point of membrane type, hydro-pneumatic spring includes single chamber hydragas spring, double chamber hydragas spring, two-stage pressure type hydro-pneumatic spring.
To improve the flexibility of Vehicle De L'Avant Blinde By Creussot suspension, need to realize hydro-pneumatic spring and two kinds of damping systems of helical spring
The flexible exchange of system.Therefore the erection support that hydro-pneumatic spring upper pin is set on the car body is needed.However this can increase spiral bullet
The degree of freedom of spring shock mitigation system leads to the movement of helical spring and deformation is uncontrolled or even helical spring can be sent out with damper
Raw abrasion.
For deficiencies of the prior art, the utility model is proposed.

The utility model can solve the above problems, after twisted seat 5 and damper upper limb 7 are installed on helical spring, by the utility model
Twisted seat limited block 3 is mounted on helical spring on twisted seat 5, to facilitate installation, the thickness c of limited block is slightly less than on helical spring
The primary clearance of upper twisted seat 5 upper surface and vehicle attached seat 1, limited block inner width d are slightly larger than two 2 both sides outer end faces of adjustment block
Distance, fall off protrusion inner width e and length f slightly larger than upper twisted seat 5 accordingly installation fit dimension, anti-dropout protrusion
External width g is slightly less than the inner width of vehicle attached seat 1.Then twisted seat 5 passes through two adjustment blocks 2 and axis pin again on helical spring
8 assemble with vehicle attached seat 1.The utility model can be limited on helical spring by twisted seat limited block 3 on design helical spring and be twisted
The relative rotation of seat 5 and vehicle attached seat 1, while the structure of vehicle attached seat and helical spring shock mitigation system is not changed, to meet
Interchangeability requirement of such panzer to helical spring shock mitigation system and hydro-pneumatic spring shock mitigation system.
It finds, using above-mentioned mounting structure, can be fully solved on helical spring 6 and damper through a large number of experiments
Dry and astringent problem occurs for limb 7, and further increases the performance and used life of product, is found through experiments that, the average of product is got over
Wild speed improves 30%.
Although the utility model has been disclosed in the preferred embodiments as above, the utility model is not limited to this.Any
