Abstract
The utility model relates to a leaf spring with less blade springs for a light duty van rigid axle suspension, and solves the problem in the laminated leaf spring for vehicles that increase in dynamic rigidity leads to a rise in the inherent frequency of the suspension, thereby affecting the riding comfort of the whole vehicle and causing high noise. The utility model provides a leaf spring, wherein, a center bolt is connected to the middle part thereof, and lathedogs are arranged on two sides thereof. The utility model is characterized in that the spring leaves constituting the leaf spring are numbered less than four, a middle gasket is arranged between two neighboring spring leaves at the joint of the center bolt, and noise elimination gaskets are arranged between lower spring leaves in the positions of the lathedogs on the two sides and neighboring spring leaves. Due to the structural improvement, friction produced by the leaf spring with less blade springs is very small if not eliminated, and the dynamic rigidity approximates to the static rigidity, thereby not only improving the riding comfort of vehicles, but also reducing the running noise.
Description
Technical field
The utility model relates to light truck dependent suspension steel spring.
Background technology
In vehicle traveling process, wheel and axletree up-down vibration, suspension system play and relax the impact that produces when automobile crosses uneven road surface, and wherein automobile leaf spring is main power-absorbing.Traditional automobile leaf spring adopts multiple-leaf spring structure (being generally 5～12), owing to there is big friction force between sheet, and along with vibration velocity increases and becomes big, not only produces noise, and friction force hinders the leaf spring distortion, influence steel spring absorption impulsive force.Main performance is exactly that the steel spring dynamic rate becomes greatly, and the suspension natural frequency raises, and has influenced the car load ride comfort.But because steel spring is when static state, friction force does not exist again, and the initial stiffness that reduces steel spring solves the load that the ride comfort problem will influence leaf spring.Guarantee load so can only sacrifice the smooth-going performance of car load now.
Summary of the invention
Big in order to solve existing automobile with the dynamic rate change that the multiple-leaf spring steel spring exists, the suspension natural frequency raises, influenced the car load ride comfort, problem such as running noises is big, the utility model provides a kind of light truck dependent suspension with few sheet spring steel spring.
Concrete structural development technical scheme is as follows:
The light truck dependent suspension comprises that with few sheet spring steel spring the middle part is provided with the steel spring of clip by center bolt connection, both sides;
The reed quantity of described steel spring is below 4, is provided with intermediate washer between the adjacent reed of center bolt junction; Between the following reed at both sides clip place and adjacent reed, be provided with anti-squeal shim.
The reed quantity of described steel spring is three, and three reeds are respectively upper reed plate, middle reed and following reed, is respectively equipped with intermediate washer between the upper reed plate of center bolt junction and middle reed, middle reed and following reed; Between the middle reed at both sides clip place and following reed, be provided with anti-squeal shim.
The material of described intermediate washer is structural carbon steel (Q235A), and its length, width and thickness are respectively 100 millimeters, 68 millimeters and 1 millimeter.
The material of described anti-squeal shim is a rubber, and its length, width and thickness are respectively 60 millimeters, 68 millimeters and 6 millimeters.
Useful technique effect of the present utility model is referring to Fig. 4, be quiet rigidity and dynamic stiffness relation curve scheme drawing, transverse axis is represented the deflection of automobile leaf spring, the longitudinal axis is represented the load that automobile leaf spring bears, Ks represents the quiet rigidity of steel spring, Kd represents the dynamic stiffness of steel spring, and δ represents the steel spring Oscillation Amplitude, and 2F represents the friction force of steel spring.Because friction force 2F, the rigidity that makes the steel spring motoring condition is greater than quiet rigidity, represents the actual rigidity of motoring condition with dynamic stiffness, and 2F is big more, and it is many more that dynamic stiffness exceeds quiet rigidity.Through the structural development to steel spring, the little or elimination of few sheet spring structure steel spring friction force makes dynamic stiffness near quiet rigidity, improves automobile pattern ride comfort, simultaneously, has reduced running noises.
