Embodiment
Silencer of the present utility model can be widely used in the place that the noise reduction of automobile braking liner, motor car engine, generator etc. produce noise, carries out noise reduction and damping to motor car engine etc.
Below for automobile brake lining plate silencer and reduce automobile brake noise method the utility model is described in further detail:
As shown in Fig. 1 and Fig. 2 and Fig. 7, the automobile brake lining plate silencer of the present embodiment structure, comprises bloop 3, and bloop 3 arranges at least two apertures 7.Aperture 7 can be through hole, also can be blind hole.As shown in Figure 1, preferred aperture 7 is through hole, and a surface of bloop arranges cover plate 2.Aperture 7 on bloop 3 is designed to blind hole, or the surface when aperture is through hole at bloop arranges cover plate 2, can change the damping characteristic of brake lining.
Preferably in aperture 7, fill damping grease 6.
Preferred aperture 7 is at least 4, and the center of circle of each aperture 7 is positioned at same circumference f.As shown in Figure 2, each aperture 7 can be uniformly distributed, and as shown in Figure 6, each aperture also can non-uniform Distribution, when each aperture non-uniform Distribution, the aperture of non-uniform Distribution with the center of circle o of circumference f for symmetric points are symmetrical arranged.
No matter aperture 7 is through hole or blind hole, and upper and lower two surfaces of bloop 3 are all smooth, are beneficial to and fit tightly with the faying surface of brake lining backboard 4 and brake piston 1.
Bloop material and structure can adopt material and the structure of prior art bloop.
As shown in Figure 3, preferred bloop is metallic composite, total thickness is 0.6-1.0mm, it is by having flexible sheet-metal layers 9 and rubber layer 8 is composited, sheet metal preferable alloy cold-reduced sheet substrate, its thickness is 0.4-0.5mm, and rubber layer 8 is high temperature resistant, resistance to braking fluid, impact-resistant nitrile butadiene rubber class preferably.Rubber layer 8 can be arranged on a surface of sheet-metal layers 9, also can be arranged on two surfaces of sheet-metal layers 9.Rubber layer 8 is all set on two surfaces of sheet-metal layers 9 and can plays better erasure effect.
As shown in Figure 4 and Figure 5, when using this silencer, silencer is arranged between brake piston 1 and brake lining backboard 4, when bloop is blind hole, the foraminate surface that arranges of bloop 3 is called surface one and arranges towards brake lining backboard 4.On the surface one of bloop 3, viscose glue 10 is set, the surface one of bloop 3 is fixedly connected on brake lining backboard 4, the position arranging aperture 7 of bloop is positioned at immediately below brake piston 1 effectively contacts with bloop 3, riveted joint can be adopted to be fixedly connected with by bloop brake lining backboard 4 in conjunction with bonding mode, directly bonding mode also can be adopted to be fixedly connected with brake lining backboard 4 by bloop 3.When aperture 7 is through hole, cover plate 2 is set on the surface two of bloop 3.Cover plate 2 is positioned at brake piston side, bloop is positioned at brake liner plate side.The mating shapes of preferred cover plate 2 and bloop 3.Brake lining friction material 5 is positioned at the other end of brake lining backboard 4.
In order to strengthen erasure effect, in aperture, inject damping grease 6.
Aperture 7 is arranged to blind hole or on the bloop 3 being provided with logical aperture 7, arranges cover plate 2 both to have played the effect changing damping, also can prevent the damping grease 6 injected in aperture 7 from overflowing when injecting damping grease 6 in aperture.In addition, cover plate is set on the surface two of the bloop arranging logical aperture 7, cover plate can with aperture 7 in be provided with the bloop acting in conjunction of damping grease, play the effect strengthening viscous damping.
When rubber layer 8 is bondd with brake lining, uniform high pressure need be applied to rubber layer and brake lining, thus silencer is bonded in brake lining.
When carrying out noise reduction to automobile braking liner, adopt following principle: the noise of brake lining is larger, the quantity of aperture is also more, the diameter of aperture is larger, namely passes through the quantity of change bloop, pore size and arrangement mode, changes the damping capacity of vibration damping sheet, thus change the inherent feature frequency of automobile brake lining plate, effectively avoid when skidding, brake lining is overlapping with the natural frequency of brake disc, reduces brake noise.
When carrying out noise reduction to brake lining, the aperture of bloop is positioned at immediately below brake piston, make aperture just to the end face of brake piston, noise reduction can be improved like this, on the circumference e that the center line that preferably center of circle of each aperture is positioned at the annular radii of brake piston is formed, such erasure effect is best.For the brake lining of different size, adopt following principle to realize noise reduction: when the decibel value of brake noise is higher, the quantity of aperture 7 is more, and little pore size distribution is more intensive; The frequency of brake noise is larger, and small aperture is larger, the abundance in hole is more.
The processing of aperture is very simple, disposable by hole and the direct impact briquetting of external form when vibration damping sheet impact briquetting.
The shape of aperture can be the arbitrary shapes such as circular, square, rhombus.The circumference of each little pore size distribution and adjusting depending on the size of brake noise and frequency at distributing position circumferentially, but follow a unified principle, be exactly, each aperture is preferably uniformly distributed, if some aperture right and wrong is equally distributed, then this aperture must be arranged in pairs, and with the center of circle of brake piston for symmetric points are symmetrical, as shown in Figure 6.The circle of the center of circle formation of each aperture, its diameter equals 1/2nd of external diameter and internal diameter sum.
Preferably, cover plate is stainless steel, and thickness between 0.3-0.5mm, and through Overheating Treatment, makes its surface have enough hardness and enough elasticity, and preferred cover plate and automobile brake lining plate backboard are fixed by snap fit and be connected.The hardness of cover plate is preferably greater than and equals HV220, and preferred tensile strength sigma b is for being more than or equal to 750MPa.
Table 1 is the hole diameter of different size brake lining bloop used, quantity and the brake piston size table of comparisons
Table 2 is the application example of the bloop of the different hole count of hippocampus M3 automobile front brake liner, according to the result that SAEJ2521 standard is tested at noise test platform.As can be seen from the table, use with a bloop, increase hole count and effectively can improve brake noise, evaluate when 8 holes are uniform and add up to 9.1 points, reach the usage requirement that main frame is supporting.
