Background technique
Leaf springs of car is elastic element the most traditional in automobile suspension system, and due to its good reliability, structure is simple, manufacturing process flow is short, cost is low and structure such as to simplify greatly at the advantage, thus is widely used.Leaf springs of car is generally combine one group by the alloy spring steel of some Length discrepancy to be similar to equal strength spring beam.In suspension systems except playing buffer function and outer, when it is settled at automobile longitudinal, and one end and vehicle frame fix during chain connection, can shoulder transmission all each to force and moment, can damping effect be played.
Leaf springs of car is when exceeding rated load, and what damping the non-constant of damping effect, almost do not have, and vehicle traveling process is not steady yet, easily rocks, makes the object on car rock swing, easily damage.The load that leaf spring on the market can bear is little, cannot support the weight of heavy load, and leaf spring is when bearing larger weight, easily causes very harsh noise.Therefore are objects of the utility model research for the problems referred to above.
Model utility content
The purpose of this utility model is to provide a kind of leaf springs of car; this leaf springs of car is made up of main spring and auxiliary spring; when automobile load is less time; main spring plays a major role; when automobile load is larger, main spring and auxiliary spring play a role simultaneously, and automobile shock is effective; and main spring can be protected, the Rigidity and strength of this leaf spring can be improved.
The technical solution of the utility model is: a kind of leaf springs of car, comprise main spring and auxiliary spring, a middle spacer is lined with between described main spring and auxiliary spring, main spring, auxiliary spring and middle spacer run through has centre bolt to make it press together, described main spring is by the first main reed, second main reed and the 3rd main reed composition, the two ends of described main spring are respectively overlapped and are had a U bolt, between main between two reed in U bolt, pad is provided with mobile block, described mobile block comprises rectangular block, three roll shafts are had side by side in described rectangular block, the diameter of described roll shaft is greater than the height of rectangular block, described U bolt both sides are provided with chute, described rectangular block both sides are provided with the slide guide post matched with chute, mobile block is slided up and down in U bolt, described auxiliary spring is made up of the first auxiliary spring sheet and the second auxiliary spring sheet.
In order to make middle spacer not easily rotate, make it stablize, described middle spacer comprises a horizontal support block, and described horizontal support block both sides are respectively equipped with block and form " work " font block.
In order to improve the Rigidity and strength of this leaf spring, making automobile shock better effects if, making the first main reed, the second main reed, the 3rd main reed radius of curvature reduces successively, the radius of curvature of the first auxiliary spring sheet is greater than the second auxiliary spring sheet.
The utility model has the advantage of: one is that this leaf springs of car is made up of main spring and auxiliary spring, when automobile load is less time, main spring plays a major role, when automobile load is larger, auxiliary spring can withstand on automobile chassis, and main spring and auxiliary spring play a role simultaneously, and it is larger that leaf spring bears weight, automobile shock is effective, has double-layer shock-absorbing protection; Two is when vehicle load is larger, and weight is born in the auxiliary spring support that can help, and can protect main spring, can improve again the Rigidity and strength of this leaf spring; Three is that between the main between two reed in U bolt, pad is provided with mobile block, can reduce the friction between reed, reed can be separated by mobile block, and micro-the moving that can be able to deform between reed, cause between reed and not easily produce harsh noise, not easily living environment around image; Four is be located between main spring and auxiliary spring to be provided with middle spacer, auxiliary spring main spring bear weight larger time, exceed the strength of main spring, auxiliary spring is enabled automatically, helps main spring to play support effect, good damping effect.
