Abstract
The invention discloses a kind of power assembly hydraulic suspension with throttling plate, comprise connection bracket, be arranged on the main spring of elasticity, upper liquid chamber and lower liquid chamber in connection bracket; On the main spring of elasticity, be provided with interior fuse; Upper liquid chamber and lower liquid chamber are separated by runner assembly, and feature is to be provided with throttling plate in this upper liquid chamber, and throttling plate and interior fuse are bolted, and between this throttling plate and interior fuse, are provided with spring. Its advantage is that this hydraulic mount can make its inside occur that liquid column resonance phenomenon delays, and has effectively extended its high frequency frequency of dynamically hardening, and then improves the anti-vibration performance of power assembly suspension system, is conducive to NVH performance and the comfortableness of car load.
Description
Technical field
The present invention relates to a kind of power assembly hydraulic suspension, relate in particular to a kind of power assembly hydraulic suspension with throttling plate.
Background technology
Hydraulic mount is due to its good vibration damping and anti-vibration performance, and in automobile power assembly suspension system, application is more and more extensive. Conventional power assembly hydraulic suspension has large damping, large stiffness characteristics under the excitation of low frequency large amplitude, is conducive to the road vibration of decaying, thereby reduces car internal vibration and noise; And under the little amplitude excitations of high frequency, easily there is dynamic hardening phenomenon, now dynamic stiffness is higher, be unfavorable for vibration isolation, the vibration that power assembly produces is very easy to be passed in car by hydraulic mount, be unfavorable for that car load NVH performance improves, therefore how eliminate or reduce the dynamic hardening phenomenon of power assembly hydraulic suspension, the anti-vibration performance that improves power assembly suspension system is had to extremely important engineering significance.
Current existing hydraulic mount is generally to reduce hydraulic mount dynamic hardening phenomenon by decoupling zero film is installed therein, improve the anti-vibration performance of power assembly suspension system, but the mode that decoupling zero film is installed is very limited for the dynamic sclerosis frequency that improves hydraulic mount, generally between 100-150Hz, and for high-power, high-revolving power assembly, dynamically sclerosis frequency requirement is between 200-300Hz, and therefore current existing hydraulic mount can not meet the requirement of this type of power assembly suspension system.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high frequency that can effectively extend hydraulic mount frequency of dynamically hardening, and effectively improves the power assembly hydraulic suspension with throttling plate of the anti-vibration performance of power assembly suspension system.
The present invention solves the problems of the technologies described above adopted technical scheme:
A kind of power assembly hydraulic suspension with throttling plate, comprise connection bracket, be arranged on the main spring of elasticity, upper liquid chamber and lower liquid chamber in connection bracket, on the main spring of described elasticity, be provided with interior fuse, described upper liquid chamber and lower liquid chamber are separated by runner assembly, in described upper liquid chamber, be provided with throttling plate, described throttling plate and described interior fuse are bolted, and between described throttling plate and described interior fuse, are provided with spring.
The bottom of described bolt is provided with interior hexagonal screw, on described interior fuse, is provided with the screwed hole matching with described bolt, and described screw bolt passes throttling plate and spring are screwed onto on described interior fuse.
Described interior fuse upper surface is provided with groove, described bolt by locking nut at described groove internal locking.
Between described bolt head inner face and throttling plate, be provided with spacing rubber.
Described runner assembly is made up of runner, decoupling zero film and flow passage cover plate, and described upper liquid chamber and lower liquid chamber are separated by flow passage cover plate, and described runner and decoupling zero film are arranged under described flow passage cover plate, and described decoupling zero film is fixed in runner.
In described lower liquid chamber, be provided with leather cup, described leather cup and the riveted joint of described connection bracket.
The main spring integral type sulfuration of described connection bracket and elasticity.
The main spring of described elasticity and leather cup are made up of natural rubber material.
Described upper liquid chamber and lower liquid chamber inside are full of liquid, and described liquid is ethylene glycol.
Compared with prior art, the invention has the advantages that:
(1) at upper liquid chamber, a throttling plate is set, and be provided with spring between throttling plate and interior fuse, under the little amplitude excitations of extraneous high frequency, throttling plate is at upper liquid chamber disturbance liquid, produce turbulent phenomenon, make hydraulic mount inside occur that liquid column resonance phenomenon delays, the high frequency that has effectively the extended hydraulic mount frequency of dynamically hardening, thereby improve the anti-vibration performance of power assembly suspension system, be conducive to NVH performance and the comfortableness of car load;
(2) set spring between throttling plate and interior fuse, it preloads and can regulate by the bolt connecting between the two, thereby makes throttling plate produce turbulent phenomenon in various degree at upper liquid chamber, meets the requirement of different dynamic assembly suspension system.
