Background technique
Leaf spring is most widely used a kind of elastic element in automotive suspension, it is wide by some but the elastic beam of an approximately equi-strength that combines of the alloy spring sheet of Length discrepancy, both can use as elastic element, the effect of leading and transmitting side direction, longitudinal force and moment can be played again.
At present, the leaf spring that market has, directly contacts between steel plate with steel plate during work and carries out sliding friction, produce slip resistance, when sliding friction is serious, when surface friction drag is larger, leaf spring rigidity increases, the corresponding increase of contact fatigue, thus reduce the fatigue life of leaf spring, also can be delivered on vehicle body rigid for road shocks, the smoothness of automobile is deteriorated, meanwhile, the sliding friction between steel plate also can produce corresponding noise.
In addition, when needing flexible in the leaf spring working procedure of prior art, the mounting type be mainly arranged on suspension bracket with mortise pin by its one end has come, and leaf spring itself can not regulate longitudinal size automatically.
Model utility content
For the deficiency that prior art exists, it is little that the purpose of this utility model is to provide a kind of surface friction drag, and fatigue strength is low, and fatigue life is long, and noise is little and automatically can regulate the new steel plate spring of longitudinal size.
For achieving the above object, the utility model provides following technological scheme:. a kind of new steel plate spring, comprise main spring and auxiliary spring, it is characterized in that: described auxiliary spring is being provided with roller unit towards the one side in main spring direction, described roller unit comprises ball base and ball, described ball base is circular arc, and ball base is provided with spherical pore, and described ball is embedded in spherical through hole.
By adopting technique scheme, auxiliary spring arranging roller unit, roller unit comprises ball, during leaf spring work, produce rolling friction by ball contact between each steel plate, the resistance that rolling friction produces is less than the resistance that sliding friction produces, thus reduces leaf spring
Rigidity, increases the fatigue life of leaf spring, and contribute to the smoothness improving automobile, and noise is little; Ball base designs is arc, makes the contact of ball base and steel plate tightr, coordinates more stable.
The utility model is set to further: described main spring comprises the first spring body and second spring body two-part, described first spring body is divided into horizontal component and curved portion, the horizontal component of described first spring body is provided with rectangular recess and the manhole identical with rectangular recess, the opening of described rectangular recess is towards the first spring body section direction, described manhole is vertical with rectangular recess direction, described second spring body is provided with joint, described joint size and rectangular recess size suitable, described joint is provided with waist through hole.
By adopting technique scheme, the joint of the first spring body is directly nested in the rectangular recess of the first spring body and is fixed connection by bolt, second spring body being used for the hole of logical bolt is arranged to waist typed through hole, bolt can move in waist typed through hole again, such design, can regulate the longitudinal size of leaf spring automatically when leaf spring works.
The utility model is set to further: described roller unit to be arranged on auxiliary spring and roller unit along the distribution of auxiliary spring surface uniform, described ball base is fixedly connected with auxiliary spring.
By adopting technique scheme, roller unit is arranged on auxiliary spring curved portion and roller unit is uniformly distributed, the horizontal component avoiding leaf spring connects because having roller unit thus making to stablize contact between steel plate, and there will not be the problem that the stress of larger problem is not concentrated.
The utility model is set to further: the opening diameter at described spherical pore two ends is less than the diameter of ball.
By adopting technique scheme, the opening diameter at spherical pore two ends is less than the diameter of ball, ensure that ball can not fall down from the spherical pore of ball base, improves the security and stability of new steel plate spring.
The utility model is set to further: described auxiliary spring is provided with size and the suitable ball recess of ball.
By adopting technique scheme, auxiliary spring is provided with ball recess, described ball recess size and ball size suitable, the ball exposing ball base spherical pore part can be embedded in the ball recess on auxiliary spring, make the connection between ball base and auxiliary spring convenient, simultaneously
The thickness of ball base can also be reduced, thus make the distance between a steel plate too far, the elasticity of leaf spring can not be improved.
