Depending on the examination and maintenance to chassis suspending cushion.Suspending cushion on automobile chassis is mainly distributed on the fixed bracket of engine and vehicle
Between frame, on transmission shaft intermediate support and on Front Leaf Spring cover board etc..
Because reciprocating motion of the pistons, cylinder combustion and its moving component can generate vibration when automobile engine works.Such as
Fruit is directly connected to engine on chassis, and chassis can be made also and then to vibrate.It will affect the handling and comfort of automobile.So
One cushion blocking to be installed between automobile engine and chassis, is transmitted on chassis so that the vibration of engine is few as far as possible,
Working principle absorbs the vibration of engine generation using the flexible deformation of cushion blocking.
On current field, the displacement position-limiting of suspending cushion used in automobile mainly passes through increase rubber bumps structure
It realizes, but pure rubber bulge-structure rigidity is lower, limit effect is undesirable, and rubber bumps failure easy to wear, to aggravate
The premature failure of suspending cushion influences the reliability and comfort of product.Therefore, present invention mainly solves engine vibration-damping devices
The problem of middle rubber layer is easy aging, reduced performance.

In view of the deficiencies of the prior art, the present invention provides a kind of engine vibration-damping device with Novel jacket pipe structure,
So that product is significantly promoted product fatigue behaviour simultaneously with good performance, improves product reliability.
The present invention is realized by following technological means solves above-mentioned technical problem:
A kind of engine vibration-damping device with Novel jacket pipe structure, ecto-entad successively include outer tube, reed layer,
The cylindrical body of rubber layer and inner sleeve；The outer tube sleeve is socketed on reed layer, is evenly arranged with four on the inner wall of the outer tube sleeve
A fin, the fin is parallel with the axis of cylindrical body, and bolt limit is provided in the upper and lower symmetrically arranged fin axial direction
Position hole, is provided with lightening hole in the left and right symmetrically arranged fin axial direction, the reed layer inner surface is fixed in outside rubber layer
Surface, the position of corresponding four fin of the reed layer form rib slot to cylinder axis to recess, and the rib slot is corresponding internal
The position of rubber layer is provided with cushion hole, and the cushion hole is located in rubber layer, the inner wall of the rubber layer and inner tube set
Outer tube wall is affixed, and the inner wall of said inner tube set is provided with latch.
Preferably, the outer tube sleeve and inner tube set are mainly made of antifriction metal (AFM) material, and the reed layer is mainly by elasticity
Metal material is made.
Preferably, the inner surface of the fin and the outer surface of rib slot recline, and the inwardly protruded side of rib slot is located at
In cushion hole.
Preferably, buffer layer is provided between the adjacent fin.
The present invention has the advantages that setting fin structure on the inside of outer tube, cushion hole is set on the outside of rubber layer, works as inner tube set
When stress moves, fin cooperates cushion hole to provide hard limit for inner tube set, while also setting between rubber layer and appearance set
It is equipped with reed layer, the rib slot to fasten with fin structure is provided on reed layer, is had between the inside and rubber layer of rib slot slow
Punching, when vibrating generation, reed layer Spontaneous Contraction and stretching, extension can absorb a large amount of vibrational energy, reduce vibration to rubber layer
Influence, improve the service life of rubber layer.
Detailed description of the invention
