Abstract
The utility model provides an engine suspension assembly which comprises an upper shell body, a lower shell body, an elastic body unit and a support arm. The elastic body unit is connected with the lower shell body, the support arm is connected with an engine, and the lower shell body is provided with a vibration isolating lining, wherein the vibration isolating lining sequentially comprises a bushing inner pipe, a framework, a vibration-reducing bushing and an outer pipe from inside to outside. By means of the engine suspension assembly, vibration transmitted to a vehicle body is greatly reduced, and the comfort of a whole vehicle is increased.
Description
Technical field
The utility model relates to a kind of engine mounting, relates in particular to a kind of engine hydraulic mount.
Background technology
The engine mounting type roughly is divided into rubber mounting, hydraulic mount, Semi-active mount and active engine mount.
Half active and active engine mount only are used for B level and above senior vehicle at present due to expensive.
Rubber mounting is because of its low price, and stable performance is widely used on various vehicles.But rubber mounting is because being subjected to structural limitations, and rigidity and damping are regulated and be difficult to satisfy simultaneously low frequency and high-frequency performance.
Hydraulic mount is because having good impact resistance, and rigidity is easily regulated and is widely used.
To improving constantly that vehicle riding comfort requires, the vibratory magnitude that vehicle body allows is more and more less along with the increased power of driving engine and vehicle structure lightweight and people.During engine vibration, the vibration of biography to vehicle body that can decay suspending.As vibration damping not, can cause the car internal vibration, the shake as bearing circle, seat, floor etc. has a strong impact on the driving comfort type.In the situation that the excitation of dynamic assembly soruce of vibration is constant, the car internal vibration is reduced, just require the good isolation characteristics that suspends.
The mounting assembly of prior art comprises as shown in Figure 1: upper shell 11 and lower house 14, upper shell 11 are connected with lower house and are connected by rivet, and support arm 12 is pressed in elastic body mechanism 13, and elastic body mechanism 13 is connected with lower house 14 by bolt.Support arm 12 is connected with driving engine by bolt.Upper shell 11 is connected with vehicle body by bolt.This suspends elastic body mechanism 13 is hydraulic structure.
Said structure is delivered to the vibration of car body by elastic body mechanism 13 decay dynamic assemblies, the anti-vibration performance that the impacts such as hydraulic cavities size, rigidity and the damping of elastic body mechanism 13 suspend, but along with the continuous lifting that people require traveling comfort, existing hydraulic mount anti-vibration performance can not meet design requirement.
The utility model content
In view of above-mentioned technical matters, the purpose of this utility model is to provide a kind of vibration that is delivered to vehicle body that greatly reduces, and has improved the engine mounting of car load traveling comfort.
Engine mounting of the present utility model comprises: upper shell; Lower house; The elastomer unit that is connected with described lower house; The support arm that is connected with driving engine, described lower house has anti-vibration bush, and described anti-vibration bush comprises from the inside to the outside successively: lining inner tube, skeleton, vibration damping bush and outer tube.
According to said structure, because engine mounting comprises: upper shell; Lower house; The elastomer unit that is connected with described lower house; The support arm that is connected with driving engine, described lower house has anti-vibration bush, described anti-vibration bush comprises from the inside to the outside successively: lining inner tube, skeleton, vibration damping bush and outer tube, therefore, improve the anti-vibration performance that suspends, the vibration that makes dynamic assembly be delivered to vehicle body increases the one-level vibration isolation, greatly reduces the vibration that is delivered to vehicle body, has improved the car load traveling comfort.
In addition, described lining inner tube utilizes tie bolt to be connected with described elastomer unit.
In addition, between described lining inner tube and described tie bolt across pad.
In addition, described support arm is connected with driving engine by bolt.
In addition, described upper shell is connected with vehicle body by bolt.
In addition, described elastomer unit is hydraulic structure.
According to said structure, because described lining inner tube is utilized described tie bolt and is connected with described elastomer unit, between described lining inner tube and described tie bolt across described pad, described support arm is connected with driving engine by bolt, described upper shell is connected with vehicle body by bolt, therefore, the dynamic assembly vibration transfer path is changed to: dynamic assembly---elastomer unit 3---anti-vibration bush---base---vehicle body.Can realize the secondary vibration damping thus, greatly improve the vibration isolation rate that suspends.In the situation that the dynamic assembly vibration level is constant, suspending than tradition can larger decay reach the vibration of vehicle body, improves the traveling comfort of car load.

The specific embodiment
Below the specific embodiment of present embodiment is elaborated.Following embodiment is only an example of present embodiment technical scheme, should not be interpreted as the restriction to the present embodiment protection domain.
Fig. 3 is the integrally-built block diagram of the engine mounting of present embodiment.As shown in Figure 3, the engine mounting of present embodiment comprises: upper shell 1; Lower house 4; The elastomer unit 3 that is connected with lower house 4; The support arm 2 that is connected with driving engine.
Fig. 2 is the cutaway view of inner structure of the engine mounting of present embodiment.As shown in Figure 2, lower house 4 has anti-vibration bush, and this anti-vibration bush comprises from the inside to the outside successively: lining inner tube 5, skeleton 6, vibration damping bush 7 and outer tube 8.
In addition, as shown in Figure 2, lining inner tube 5 utilizes tie bolt 10 to be connected with elastomer unit 3.
And, between lining inner tube 5 and tie bolt 10 across pad 9.
In addition, support arm 2 is connected with driving engine by bolt, and upper shell 1 is connected with vehicle body by bolt.
In addition, in present embodiment, elastomer unit 3 is hydraulic structure.
According to said structure, because engine mounting comprises: upper shell 1; Lower house 4; The elastomer unit 3 that is connected with lower house 4; The support arm 2 that is connected with driving engine, lower house 4 has anti-vibration bush, this anti-vibration bush comprises from the inside to the outside successively: lining inner tube 5, skeleton 6, vibration damping bush 7 and outer tube 8, therefore, improve the anti-vibration performance that suspends, the vibration that makes dynamic assembly be delivered to vehicle body increases the one-level vibration isolation, greatly reduces the vibration that is delivered to vehicle body, has improved the car load traveling comfort.
According to said structure, because lining inner tube 5 is utilized tie bolt 10 and is connected with elastomer unit 3, between lining inner tube 5 and tie bolt 10 across pad 9, support arm 2 is connected with driving engine by bolt, upper shell 1 is connected with vehicle body by bolt, therefore, the dynamic assembly vibration transfer path is changed to: dynamic assembly---elastomer unit 3---anti-vibration bush---base 4---vehicle body.Can realize the secondary vibration damping thus, greatly improve the vibration isolation rate that suspends.In the situation that the dynamic assembly vibration level is constant, suspending than tradition can larger decay reach the vibration of vehicle body, improves the traveling comfort of car load.
