Abstract: A vibration damping shim structure is provided, which not only can sufficiently exert vibration damping effect in a wide range of temperatures, but also can prevent a squeal phenomenon particularly in low temperatures. A rubber coating layer a1 is formed on one side of a first constraint plate a2 of a metallic plate and a second constraint plate a4 is stuck to the other side of the first constraint plate a2 with a adhesive layer a3 placed in-between. The ratio of the thickness of the first constraint plate a2 to a sum total of the thickness of the back plate b1 forming a disc brake B and the second constraint plate a4 is taken as within 0.1 to 0.2, and the second constraint plate a4 is used so as to be brought into contact with the back plate b1.

Abstract: A squeak preventing shim for a disk brake for an automobile has a squeak preventing effect, even if no lubricant is used, and also prevents decreased durability due to buckling, flow, etc. A shim construction is formed with a plurality of grooves or recesses in rubber layers 2 disposed on two surfaces of a metal plate in a rubber coated member. Owing to these grooves or recesses, apparent transversal elastic modulus of the rubber layers is lowered and a squeak preventing effect due to vibration in a parallel direction to the shim can be obtained, even if no lubricant is used. Further, since longitudinal elastic modulus does not vary much, the shim construction is durable.

Abstract: A constraint type vibration damping material, which exhibits a high vibration damping performance and can realize easiness of processing and a low cost at the same time, is provided, in which a polymer viscoelastic layer made of rubber, etc. is formed on at least one surface of a rigid body such as a metal plate, etc. and a hard cover layer having a rigidity modulus greater than that of the viscoelastic layer and smaller than that of the rigid body. Since the hard cover layer having a great rigidity modulus acts as a constraining material, which forms as the result a pair with the rigid body. Further, since the polymer viscoelastic layer and the hard cover layer can be formed by continuous fabrication steps, it can be advantageous from the point of view of the cost.

Abstract: In order to provide a shim for preventing brake squeal in a disk brake, which can decrease high frequency noise (squealing phenomena) produced at braking, a rubber coated metal, in which a rubber layer is disposed on one surface of a metal plate is used and a pressure sensitive adhesive layer is disposed directly on the other surface of the metal plate, the pressure sensitive adhesive layer may include a primer layer on the other surface of the metal plate. The pressure sensitive adhesive layer of this shim structure serves as an adhesive portion to be stuck to a backplate of a disk brake pad. Since the pressure sensitive adhesive layer is disposed on the metal plate, the pressure sensitive adhesive layer is never peeled off from the rubber coated metal and its damping action (brake squeal preventing action) is maintained.
