Description
Technical field
The utility model relates to auto parts and components, is specifically related to a kind of automobile power assembly suspending device.
Background technique
In the last few years, along with Automobile Design develops to high pulling torque, lightweight direction, cause the vibration between motor and the vehicle body to transmit aggravation, make the NVH characteristic degradation of car load, traditional dynamic assembly suspension generally adopts rubber mounting or hydraulic mount, it can not satisfy motor well with the vibration isolation requirement between vehicle frame, thereby influences the rideability of vehicle, reduces riding comfort.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of automobile power assembly wideband vibration isolation hydraulic mount device, can isolate the transmission of engine luggine and noise effectively, the vibration when especially isolating engine idle; Compact structure is suitable for installing; Reliable operation, anti-vibration performance is good.
For achieving the above object, automobile power assembly wideband vibration isolation hydraulic mount device of the present utility model comprises housing and base, and described housing is fixed on the described base; Be provided with inertia channel body and the counterdie of metal frame, rubber spring, decoupling zero film, built-in liquid flow path in the cavity of housing and base composition, metal frame is arranged between housing and the rubber spring, and sulfuration is connected metal frame with rubber spring; Decoupling zero film, inertia channel body, counterdie are arranged on the lower end of the cavity of housing and base composition, form upper liquid chamber between decoupling zero film and the inertia channel body, form liquid chamber down between inertia channel body and the counterdie, liquid is by flowing in the liquid flow path in the inertia channel body in the upper and lower liquid chamber; The metal frame inner chamber is provided with support arm, adopts interference fit between the two.
Described inertia channel body is provided with multiple solution lotus root hole.
After having adopted technique scheme, by mobile generation linear loss and the restriction loss of liquid in the inertia channel body, the significantly vibration (vibration damping) of decay power assembly fast, when the motor dither, inertia channel produces dynamically sclerosis, rely on the multiple solution lotus root hole on the inertia channel body to isolate the vibration of power assembly this moment in the wideband section, and namely hydraulic mount plays the purpose of isolating engine luggine.The utility model has taken full advantage of good low frequency vibration damping ability and the multiple solution lotus root hole vibration isolation features under high frequency of hydraulic mount, thereby in wide band more, isolate the transmission in the car of engine luggine, noise, remedied rubber mounting and the conventional hydraulic excessive wretched insufficiency of high frequency dynamic stiffness that suspends, better improve the NVH performance of car load, improved the riding comfort of vehicle.Between housing and base, decoupling zero device complete closed, thereby compact structure are suitable for installing the utility model with the shock-damping structure design; Reliable operation, anti-vibration performance is good.
