Description
Technical field
The present invention relates to Semi-active mount technical field, more particularly to the Semi-active mount that a kind of runner is variable.
Background technology
Nowadays, auto NVH problem is always to annoying the technical barrier of people, and the vibration effect of automobile riding comfort
And the life-span of vehicle.Automobile engine is the main exciting source on automobile, and its vibration can be delivered to driver's cabin by chassis,
Cause steering wheel and seat to be shaken, influence the operation of driver, and deepened the fatigue of driver.It is peace preferably to solve method
Mounted engine suspension is vibrated to isolate, and therefore, research technique is simple, and cheap, the suspension of superior performance is particularly important.Commonly
Although pure glue suspension processing technology it is simple, price is relatively low, and it is limited in that damping is relatively low, easily occurs dynamic during high frequency
Hardening, therefore anti-vibration performance is poor；Common hydraulic mount adds the form of decoupling film using inertia channel, in low frequency large amplitude
Larger damping can be produced, in high frequency, due to decoupling the effect of film, can use and alleviate high frequency dynamic hardening to a certain extent
Phenomenon, but its damping and rigidity are non-adjustable, and dynamic stiffness is still larger during high frequency.
People require there is big rigidity, big damping characteristic when being suspended at low frequency large amplitude, have during the small amplitude of high frequency it is small just
Spend small damping characteristic, it is clear that common hydraulic mount can not meet such requirement.Therefore, people are directed to exploitation half actively
Suspension or active engine mount, make damping and rigidity adjustable extent big.Active engine mount needs to rely on outside energy to offset vibration, power consumption
It is larger, but its key is processing technology complexity, and fault rate is larger, is difficult to current technology level.It presently, there are
Several half active hydraulic mounts, main embodiment have：(1) form of control decoupling film rigidity, by decoupling film in hydraulic cavities
Form an aeroseal chamber, open an aperture on suspension wall and make air chamber and atmosphere, if a magnetic valve by aperture clogs or
Open, the rigidity of film is decoupled with control, in the embodiment, the sealing of air chamber is more difficult, should if there is leakage or into gas
Semi-active mount fails.(2) form of bend flow channel, such as Chinese patent literature disclose a kind of active hydraulic mount of bend flow channel half
[application number：201410228440.2], it is characterized in that, in suspension and runner body sidewall opening, add variable flow valve and driving becomes
The electronic control mechanism that valve rotates is flowed, the Electronic Control precision of embodiment requirement is higher, and seals more difficult, the sealing of addition
Circle and O-ring also increase cost.(3) electric current becomes and magnetic current deformation type, the embodiment are changed by applying electric current or magnetic field
The viscosity of variable damping liquid, but its magnetic-particle easily settles, and causes to suspend degradation.
Therefore, it would be highly desirable to need to provide a kind of simple in construction, good Semi-active mount of isolating affection.
