Abstract
The invention discloses a hydraulic power train mount with a throttle disc. The hydraulic power train mount comprises a connecting support, an elastic mainspring, an upper liquid chamber and a lower liquid chamber, wherein the elastic mainspring, the upper liquid chamber and the lower liquid chamber are mounted on the connecting support. An inner core is arranged on the elastic mainspring, and the upper liquid chamber and the lower liquid chamber are partitioned via a passageway assembly. The hydraulic power train mount is characterized in that the throttle disc is arranged in the upper liquid chamber and connected with the inner core via bolt, and a spring is arranged between the throttle disc and the inner core. The hydraulic power train mount with the throttle disc has the advantage that liquid column resonance phenomenon therein can be postponed, and high dynamically hardening frequency can be effectively prolonged, so that vibration isolation performance of the hydraulic power train mount can be improved, and NVH (noise vibration and harshness) and comfort of a whole car are facilitated.
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 the throttling dish.
Background technology
Hydraulic mount is used more and more widely in automobile power assembly suspension system owing to its favorable damping and anti-vibration performance.Conventional power assembly hydraulic suspension has big damping, big stiffness characteristics under the excitation of low frequency large amplitude, help the road vibration of decaying, thereby reduces car internal vibration and noise; And under the little amplitude excitations of high frequency; Occur dynamic hardening phenomenon easily, this moment, dynamic stiffness was higher, was unfavorable for vibration isolation; The vibration that dynamic assembly produces is very easy to be passed in the car through 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 extremely important engineering significance.
Present existing hydraulic mount generally is to reduce the dynamic hardening phenomenon of hydraulic mount through the decoupling zero of portion's installation within it film; Improve the anti-vibration performance of power assembly suspension system; But the mode that the 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 dynamic assembly, the frequency requirement of dynamically hardening is between 200-300Hz, and therefore present existing hydraulic mount can not satisfy the requirement of this type of power assembly suspension system.
Summary of the invention
Technical matters to be solved by this invention provides a kind of high frequency that can effectively prolong hydraulic mount frequency of dynamically hardening, and effectively improves the power assembly hydraulic suspension of band throttling dish of the anti-vibration performance of power assembly suspension system.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
A kind of power assembly hydraulic suspension with the throttling dish; Comprise the connection support, be arranged on the elasticity master's spring, upper liquid chamber and the following liquid chamber that connect on the support; Described elasticity master's spring is provided with interior fuse, and described upper liquid chamber is separated through the runner assembly with following liquid chamber, is provided with the throttling dish in the described upper liquid chamber; Described throttling dish and described interior fuse are provided with spring through bolted connection between described throttling dish and the described interior fuse.
The bottom of described bolt is provided with interior hexagonal screw, and described interior fuse is provided with the tapped bore that matches with said bolt, and described screw bolt passes throttling dish and spring are screwed onto on the described interior fuse.
The fuse upper surface is provided with groove in described, and described bolt is locked in described groove through jam nut.
Be provided with spacing rubber between described bolt head inner end surface and the throttling dish.
Described runner assembly is made up of runner, decoupling zero film and flow passage cover plate, and described upper liquid chamber is separated through flow passage cover plate with following liquid chamber, and described runner and decoupling zero film are arranged under the described flow passage cover plate, and described decoupling zero film is fixed in the runner.
Be provided with leather cup in the liquid chamber under described, described leather cup is riveted with the described support that is connected.
Described connection support and the sulfuration of elasticity master spring integral type.
Described elasticity master's spring and leather cup are processed by the India rubber material.
Described upper liquid chamber and the inner full of liquid of following liquid chamber, described liquid is ethanediol.
Compared with prior art, the invention has the advantages that:
(1) at upper liquid chamber a throttling dish is set, and is provided with spring between throttling dish and the interior fuse, under the little amplitude excitations of extraneous high frequency; The throttling dish is at upper liquid chamber disturbance liquid; Produce turbulent phenomenon, make hydraulic mount inside the liquid column resonance phenomenon occur and delay, the high frequency that has effectively the prolonged hydraulic mount frequency of dynamically hardening; Thereby improve the anti-vibration performance of power assembly suspension system, help the NVH performance and the traveling comfort of car load;
(2) set spring between throttling dish and the interior fuse, its preload can be regulated through bonded assembly bolt between the two, thus envoy's flow table produces turbulent phenomenon in various degree at upper liquid chamber, satisfies the requirement of different dynamic assembly suspension system.
