The lower surface of ontology is arranged in clamping plate, and the convex ribs for cooperating leaf end groove are provided in the middle part of upper clamp plate, can prevent
Reed misplaces when running car.
As further embodiment of the embodiment of the present invention: upper clamp plate and lower clamp plate are all made of the low Q235 material system of hardness
Make, raw material is easy to get, easy to process.
As further embodiment of the embodiment of the present invention: ontology is by the way that epoxy glue is Nian Jie with upper clamp plate and lower clamp plate respectively
One, bonding fastness are good.
As further embodiment of the embodiment of the present invention: being provided with positioning pin, positioning pin and leaf spring end in the middle part of lower clamp plate
The pad hole of head matches, and can prevent this product from falling off in leaf spring lifting and leaf spring motion process.
As further embodiment of the embodiment of the present invention: positioning pin is fixed on the middle part of lower clamp plate by the way of welding,
Connectivity robustness is good, is further ensured that this product is not easy to reverse and fall off.
As further embodiment of the embodiment of the present invention: this product is made of multiple material, and existing gasket is single
Polyurethane materials gasket, polyurethane materials hardness is low, easy to aging, and abrasion is easy to when by external force and is fallen off, each spring is caused
Piece directly contacts and increases contact fatigue, reduces the service life of leaf spring.The upper clamp plate, lower clamp plate of this product are Q235S materials
Material, highly polished, wearability is strong, shock resistance, can reduce the dry friction and contact fatigue between reed, extends the use of leaf spring
Service life reduces noise.The intermediate body member of end gasket is nylon material, flexible good, can improve vehicle running smoothness.
As further embodiment of the embodiment of the present invention: the quantity of positioning pin is two, facilitates end gasket accurate, firm
Positioning.
Compared with prior art, the beneficial effect of the embodiment of the present invention is:
This product is arranged convex ribs in the middle part of upper clamp plate, and the groove of convex ribs and leaf end cooperates, hair when can prevent running car
The phenomenon that raw reed dislocation；
This product structure is simple, manufacture it is easy to assembly, will using nylon production ontology and Q235 material made of upper clamp plate, under
This product of the cementing production of clamping plate is mounted between leaf spring blade, is reduced dry friction and contact fatigue between reed, is extended
The service life of leaf spring, reduces noise, improves the ride comfort of running car；
Positioning pin in the middle part of this product lower clamp plate is mounted in the pad hole of leaf spring end, prevents this product in leaf spring lifting and plate
It falls off in spring motion process, prospect of the application is wide.
