The said damping body of the present invention comprises any material that has the higher material damping ratio, enough dampings can be provided, and divides solid damping material and liquid damping material two big classes.The solid damping material comprises the viscoelasticity and the viscoplastic macromolecular material of high damping, as high-damping rubber, high-damping polyurethane, superplasticity silicone rubber, asphalt rubber, and operating temperature under be solid-state high damping modified pitch sill etc., the material damping of these damping materials is higher than very, reach more than the 30-50%, be different from the general elastic material or the viscoelasticity elastic material of damping slightly, as the rubber material damping ratio have only about 2-5%; The liquid damping material is stable performance, volatile, not ageing-resistant high viscosity liquid, for example is the modified pitch of viscous state etc. under silicone oil and the operating temperature.Solid damping material of the present invention and liquid damping material also comprise with above-mentioned damping material and are matrix, are added with the material of other packing, as add short fibre, mica flour can increase the damping material internal damping, adding rubber powder can increase the elasticity of material, adds the heat-conducting property that steel fiber can increase material.
The said restraining plate of the present invention can be the similar reed of shape, rigidity less than reed, any metal or plastic plate or section bar that the ratio of rigidity damping material is big, as steel plate, Steel Spring Plate, nylon sheet etc.
For the solid high damping material, can adopt modes such as pressure sensitive adhesive is sticking, chemical bonding, hot melt, sulfuration, cast, coating, clamping, parcel to connect with reed or restraining plate.
For the liquid high damping material, the liquid damping material partly or entirely is full of the space around the leaf spring, and the present invention specifically can take following several scheme:
Be filled with between the adjacent reed of liquid damping material or between reed and the restraining plate around be provided with seal or sealing configuration, constitute one or more damping chambers, the liquid damping material seal is in this chamber.
Reed periphery after superimposed is provided with seal, and the liquid damping material is set in the seal, and it is full of the space around the reed at least in part.
Because liquid can flow, in order to keep the spacing between damping chamber thickness and the reed, be provided with the spacing part being filled with between the adjacent reed of liquid damping material when being squeezed.
Seal and spacing part have certain elasticity, guarantee that adjacent reed does not contact and weares and teares, and does not hinder relatively moving of reed yet;
Be subjected to the infringement of external environment condition for fear of damping material, single reed group or whole leaf spring can be provided with protective layer.Protective layer should have following function: 1) leaf spring and damping body are had protective action, as prevent that ultraviolet irradiation, one-level from avoiding contacting etc. with water, oil, harmful gas; 2) the extra effect of tightening is played in damping to solid.3) the liquid damping material is played seal action, can be in the functional unification of seal.
The present invention is owing to be provided with damping body on the reed surface, and when leaf spring occured bending and deformation or vibrate, damping body will produce being cut into main imposed deformation, thereby the vibrational energy that absorbs, consumes makes the vibration of leaf spring weaken rapidly.Because avoided and the contacting of water, oil and air, leaf spring is difficult for getting rusty, the damping characteristic of leaf spring is stable, does not have directly contact and wearing and tearing between the reed, does not have noise, thus the vibration damping of leaf spring is stable, reliably.
