Improve.
Brief description of the drawings
Fig. 1 is a kind of structural representation of high-performing car resonance block proposed by the present invention.
Embodiment
Below, technical scheme is described in detail by specific embodiment.
As shown in figure 1, Fig. 1 is a kind of structural representation of high-performing car resonance block proposed by the present invention.
Reference picture 1, a kind of high-performing car resonance block that the embodiment of the present invention proposes, including：Rubber bodies 1, the rubber
Colloid 1 is cylindrical body, and one end of rubber bodies 1 is provided with the mica spacer 2 being secured to, and mica spacer 2 is close to the side of rubber bodies 1
Provided with the metallic gasket 3 to be reclined with it；Rubber bodies 1 are provided with annular groove 101 close to the periphery of the one end of mica spacer 2；Rubber bodies 1 are provided with
The centre bore 102 of mica spacer 2 and metallic gasket 3 is penetrated, the inside of rubber bodies 1 is provided with what is be circular layout around the centre bore 102
Mass 4, mass 4 are located at side of the annular groove 101 away from metallic gasket 3.
The present invention in one end of rubber bodies 1 by setting mica spacer 2, to utilize heat-insulated, the heat-resisting quantity of mica spacer 2
The heat on blast pipe can be made can not to be transferred directly to rubber bodies 1, to extend the service life of rubber bodies 1；By in mica mat
Piece 2 sets metallic gasket 3 close to the side of rubber bodies 1, strengthens the rubber bodies 1 with the high-yield strength using metallic gasket 3 and pacifies
The intensity in dress face；By setting mass 4 in rubber bodies 1, ring is set close to the periphery of the one end of mica spacer 2 in rubber bodies 1
