By this spring pad, spring is supported by damping.That is, spring by noise reduction, and can not produce sharp sound or creak sound relative to car body in the process of moving because spring moves.In addition, spring prevents from being corroded by sacrificing positive pole.Embedded piece supporting sacrificing positive pole, make compared with known prior art, sacrificing positive pole can be designed to be very thick, and ensures that spring is not corroded within the long period.Thus by the simple structure of this spring pad, spring is not only supported well, is also subject to reliable protection for weather conditions and external action.
Matrix preferably by have better shock absorbing characteristics, be easy to process elastomer form, make spring by noise reduction and undesirable noise can not be produced.Be applicable to adopting such as thermoplastic elastomer (TPE) or rubber for this reason.By this material, do not eliminate noise by means of only to helical spring supporting, and the manufacture of matrix is also simple especially and cheapness.
Design matrix like this, makes it hold spring and prevents from skidding.For this reason, be such as provided with the fixing protuberance on edge or be provided with central concave.In addition, matrix also can be designed with retaining piece, and spring screws or is inserted in described retaining piece.This retaining piece not only reliably fixing spring, also simplify the assembling of spring pad on spring.
In order to hold sacrificing positive pole, described matrix decision design has one or more groove.In this way, the spring side side of spring (that is towards) of sacrificing positive pole and matrix flushes in one plane.That is, an even curface is formed by the spring side of sacrificing positive pole and matrix the side of spring (that is towards).Dirt and stone is avoided to assemble on the surface of spring side and damage spring in this way.In addition, sacrificing positive pole can not cover the dirt that may weaken the protected effect of sacrificing positive pole.
Embedded piece embeds in the groove of matrix equally.It is contemplated that embedded piece is only placed on matrix, or also by substrate ring around.Correspondingly, embedded piece is bonding with matrix, or is encapsulated by the material injection of matrix.But the spring side that it should be noted that embedded piece when embedded piece is surrounded by matrix completely only cover by the elastic material of the layer of matrix.The supporting role of embedded piece for sacrificing positive pole must not be damaged.By embedding in matrix by embedded piece, also creating the aiding support to matrix, preventing matrix from occurring undesirable distortion or caving in thus.
Specify in a preferred embodiment, embedded piece directly abuts on sacrificing positive pole.Thus, embedded piece can play its supporting role for sacrificing positive pole well.When sacrificing positive pole is placed on embedded piece with whole circumference, this also optimizes supporting functions further.That is, the whole bottom side of sacrificing positive pole is embedded into part supporting.In order to sacrificing positive pole is fixed on embedded piece, such as, can adopt bonding.Embedded piece also together can be surrounded by matrix with sacrificing positive pole, makes to realize fixing by matrix self.For this reason, embedded piece and sacrificing positive pole can by after be injected with elastomer, or form the recessed groove in side in the base.Embedded piece and sacrificing positive pole preferable shape are placed in matrix with engaging.Embedded piece and sacrificing positive pole to be not only bearing in well thus on matrix and to be prevented from skidding, but also dirt and stone can be avoided to enter in the compound body of embedded piece and sacrificing positive pole and damage spring and matrix.
Sacrificing positive pole is made up of non-precious metal.Such as be suitable for zinc, magnesium or aluminium as the material for sacrificing positive pole.It is 1.5mm that the thickness of sacrificing positive pole is preferably at least 1mm, particularly preferably thickness.Guarantee that sacrificing positive pole plays its function in sufficiently long time range thus, and reliably prevent spring to be corroded.In addition, sacrificing positive pole is preferably designed to the ring closed, and makes spring pass through area large as far as possible and is formed with anode material and contact.This structure also highly stable and be easy to manufacture.
Embedded piece is by firm material, as metal or polymer are formed, wherein preferably adopt the structure be made of plastics.By this way, embedded piece is not only enough firm, but also gently, can be produced cheaply in addition.The thickness of embedded piece is preferably at least 2mm, is particularly preferably at least 3mm.Be proved to be advantageously, the ratio of the thickness of sacrificing positive pole and the thickness of embedded piece is 1 to 2, sacrificing positive pole is supported best and does not damage the damping effect of matrix.The structural design of the closed ring of embedded piece also can realize the particularly preferred supporting to sacrificing positive pole, and reliably avoids distortion or the fracture of sacrificing positive pole.
Accompanying drawing explanation
The present invention is set forth further below in conjunction with preferred embodiment.In the accompanying drawings:
Fig. 1 illustrates according to the sectional drawing being supported with the spring pad of spring of the present invention,
Fig. 2 illustrates the detail sectional view of the spring pad of Fig. 1,
Fig. 3 illustrates the details three-dimensional view of the spring pad of Fig. 1.
Embodiment
Spring pad 1 shown in Fig. 1 is arranged in Motor Vehicle, and at a side bearing helical spring 2, at opposite side, spring pad 1 is placed on unshowned spring-leaf retainer, and is positioned at helical spring (also claiming spring below) thus between 2 and spring-leaf retainer.
Spring pad 1 comprises the matrix 10 be made up of elastomer.This matrix 10 for support spring 2, and makes spring relative to car body by noise reduction.For this reason, matrix 10 is by the vibration-absorptive material of softness, make as rubber.Spring pad 1 also comprises sacrificing positive pole 20.This sacrificing positive pole 20 is placed in spring side, thus described sacrificing positive pole is directly contacted with spring 2.Because sacrificing positive pole 20 is made, so this sacrificing positive pole 20 has the corrosion-resisting function to spring 2 by non-precious metal, as zinc.The embedded piece 30 be made up of sturdy material is also embedded with between sacrificing positive pole 20 and matrix 10.Sacrificing positive pole 20 is supported by embedded piece 30.
According to the design proposal according to spring pad 1 of the present invention, spring 2 is not only supported by damping, but also is securely placed and is corroded.By settling the embedded piece 30 supported sacrificing positive pole 20, this sacrificing positive pole 20 can be designed to be very thick.Thus, the protective action of sacrificing positive pole 20 can maintain the long period.If lack embedded piece 30, then this sacrificing positive pole 20 may the rapid embrittlement or less desirable bending deflection occurs self due to the soft material of matrix 10, thus cause reliably protecting spring 2 not to be corroded again.
Matrix 10 has columniform retaining piece 11, this retaining piece 11 fixing spring 2 and prevent it from moving.For this reason, fixed block 11 is designed with depression 111, and helical spring 2 can embed in this depression 111.As shown in Figure 2, described depression 111 almost extends along the whole circumference of retaining piece 11, to hold the as far as possible large portion's section of spring 2.By this retaining piece 11, make the assembling of spring 2 very easy, as long as because sleeve is just enough on matrix 10 simply by spring 2.In addition, matrix 10 arranges fixed block 12, this fixed block 12 is for being fixed on spring-leaf retainer by spring pad 1.
In addition, matrix 10 is designed with groove 13, and this groove 13 is for holding sacrificing positive pole 20 embedded piece 30.Groove 13 so designs, and the compound body shape be made up of with embedded piece 30 sacrificing positive pole 20 is placed in matrix 10 with engaging.Thus, prevent sacrificing positive pole 20 and embedded piece 30 to skid, and prevent dirt or stone from entering, the damage of described dirt or stone possibility spring 2 or matrix 10.In addition, sacrificing positive pole 20 and embedded piece 30 at least local by after be injected with the material of matrix 10, thus formed compound body fixed reliably.In addition by this way, embedded piece 30 also plays the effect of stabilized matrix 10.Also know in fig. 2 and illustrate, matrix 10 and sacrificing positive pole 20 all flush in spring side in plane E.Prevent dirt to be attached on sacrificing positive pole 20 thus and damage the function of sacrificing positive pole.Thus, the stone that may damage spring 2 also can not be assembled on sacrificing positive pole 20.
Sacrificing positive pole 20 is bonding with embedded piece 30, and is directly placed on the upside 31 of embedded piece 30 with whole bottom surface 21.Thus, embedded piece 30 can play its protective function for sacrificing positive pole 20 best.In addition, the bonding compound body preparing this sacrificing positive pole 20 and embedded piece 30 is also be dirt cheap and be easy to.See Fig. 3, no matter sacrificing positive pole 20 or embedded piece 30 all has loop configuration.In this case, sacrificing positive pole 20 is king-sized with the surface of contact of spring 2, and is very reliable to the protective action of spring 2.Sacrificing positive pole 20 and embedded piece 30 also form firm compound body relative to softer matrix 10, and keep stable thus in longer life time.
Sacrificing positive pole 20 has the thickness of 1.5mm, and obviously thus designs thicker than sacrificing positive pole well known in the prior art.Thus, within the very long time, spring 2 is prevented to be corroded, because material can not be used up or consume in advance.In order to support the sacrificing positive pole 20 be made up of softer non-precious metal, it is thick that embedded piece 30 is designed to 3mm.By this way, sacrificing positive pole 20 and embedded piece 30 form stable compound body, and the cushioning effect of maintenance and matrix 10.Embedded piece 30 is made up of firmer polymer, and this material is not only comparatively light, and can by especially simply and manufacture at an easy rate.
