Description
Technical field
This utility model is related to a kind of automobile leaf spring, and specifically a kind of few piece variable cross-section automotive plate spring is total
Become.
Background technology
Leaf spring is widely used in the automotive fields such as Medium or severe type cargo vehicle, mine car and passenger vehicle, in automotive suspension
The effect connecting vehicle bridge and damping is played in system.In vehicle traveling process, wheel and axletree up-down vibration, suspension system rises
To the effect relaxing the impact producing during vehicle travels uneven road surface, wherein automobile leaf spring is main power-absorbing, its matter
Amount quality plays vital effect to vehicle stability, safety.Traditional leaf spring is produced as preventing the disconnected of reed
Split and lead to body sway, its design all takes the scheme of multi-disc number although ensure that the safety of leaf spring product, and it is right but to ignore
The making full use of, thus causing the waste to iron and steel resource and manufactured energy of material.Whole suspension system weight accounts for car load certainly
Nearly the 7% about of weight, thus the lightweight realizing leaf spring has important effect to mitigating car load deadweight.Traditional multiple-leaf spring
Structure due to piece between there is larger frictional force, and increase with vibration velocity and become big, not only produce noise, and frictional force
Hinder leaf spring deformation, impact leaf spring absorbs impulsive force.
Content of the invention
The purpose of this utility model is to provide for a kind of friction that can reduce between plate spring sheet, and the few piece reducing noise becomes
Section automobile leaf spring assembly.
The technical scheme of technology of the present utility model is：
Few piece variable cross-section automotive plate spring assembly includes the thickening plate spring sheet with flat segments in the middle of two panels, and plate spring sheet is thick
Degree gradually thinning to two ends from flat segments, at steel plate spring assembly flat segments, above the first plate spring sheet and two panels plate spring sheet it
Between be provided with intermediate washer, and fixed with the screw through centre bore, in cancave cambered surface, the first plate spring sheet two ends are provided with grasswort to nut,
Second plate spring sheet one end is provided with bag ear, is provided with bushing in described grasswort, and bushing is threaded, and passes through outer at the second plate spring sheet two ends
Anti-attrition pad installed by hex(agonal)screw, and nut down, is in addition provided with groove in the first plate spring sheet two ends convex arc surface side, in the second leaf spring
Anti-attrition pad in piece two ends is provided with tongue, and described tongue and groove is mutually identical, and two panels plate spring sheet is in neutral straight section and two ends anti-attrition
It is affixed at pad, remainder gap uniformly becomes big by middle to both sides.
The beneficial effects of the utility model are：
1st, few flat spring quality is little
Compared with multi-disc spring-mass, quality can reduce 30% ~ 50% to few flat spring, when the load of spring, rigidity are identical
When, spring is changed system into after 3 by 14, and spring-mass is reduced to 56.84kg by 121.52kg, decreases 53%, and spring life
Improve 30% ~ 40% about.
2nd, improve automobile ride
During camber of spring, due to piece between relative displacement produce friction, the more frictional resistance is also bigger for number of spring leaf.Spring exists
During micro breadth oscillation, due to frictional resistance effect, spring rate is made to increase, it sometimes appear that spring ' locked ' phenomenon, thus ground
Face impact is delivered on vehicle body rigidly, so that automobile ride is degenerated.Some data show, when spring amplitude is reduced to by 50mm
During 1mm, many flat springs（6）Rigidity increase nearly 6 times, and few flat spring（2）Rigidity increases nearly 2 times.Therefore reduce spring
Between piece, frictional resistance contributes to improving automobile ride.Due to above reason, few flat spring more and more obtains on automobile
Application and development.
3rd, this plate spring structure mainly makes leaf spring reach the effect of approximate iso-stress beam, thus reach raising life of plate spring,
Reduce the effect of weight.This structure is mainly used in long Few Leaf Spring, and this heavily stressed, light-weighted leaf spring is also not
Carry out the development trend of leaf spring.
4th, the first plate spring sheet bushing adopts screw-thread bush, and between bushing and bearing pin, screw thread cooperation is even closer, reduces friction,
Reduce noise.
5. between the plate spring sheet of steel plate spring assembly end one or two, adopt anti-attrition pad 1）, increase leaf spring between gap, reduce
Frictional force during camber of spring.2）, anti-attrition pad by part be rubber, car making an uproar in running can be greatly reduced
Sound.
6th, one, two plate spring sheet product center hole Jun Shipian hole, the different length of two ends stretched length.Camber curvature is different, excellent
Point preferably coordinates stationarity before and after vehicle bridge.
