Abstract
The utility model discloses an active control type engine hydraulic mount, and belongs to the field of parts for shock absorption of automobiles. The hydraulic mount comprises a main spring framework, a rubber main spring and a vibration exciter, wherein the main spring framework and the rubber main spring are integrally vulcanized and the vibration exciter is fixedly arranged at the bottom of the inside of a base. The hydraulic mount further comprises a decoupling membrane and a top membrane. The decoupling membrane and the rubber main spring form a lower liquid chamber, the top membrane and the rubber main spring form an upper liquid chamber in a vulcanized mode, the upper liquid chamber is communicated with the lower liquid chamber through an inertia channel defined by the decoupling membrane and the rubber main spring, and the output end of the vibration exciter is connected with the decoupling membrane in a vulcanized mode. The hydraulic mount has the advantages that a bottom membrane in the prior art is changed into the top membrane, a series of problems brought by vulcanized connection between the bottom membrane and the vibration exciter are avoided, and the structure and the process are simple.
Description
Technical field
The utility model relates to the vibration damper that automobile technical field is used, the active controlled engine hydraulic pendant that particularly a kind of damping is used.
Background technique
In the last few years, along with the raising of people's living standard, people's door is more and more higher to the requirement of vehicle riding comfort, and along with Automobile Design is to high pulling torque, lightweight future development, cause the vibrations transmission aggravation between motor and vehicle body, make the english abbreviation of NVH(noise, vibration and the sound vibration roughness (Noise, Vibration, Harshness) of car load) characteristic degradation, traditional passive suspending can not meet motor with the vibration isolation requirement between vehicle frame.Thisly passively can also play good vibration isolating effect when being suspended at low-frequency vibration, but when motor just starts, vibration frequency is just higher, due to the restriction to liquid fluidity of inertia channel, causes the vibration that can not isolate upper frequency.
In the last few years, the research suspending of using for automobile is more and more, the Jilin University many at this area research applied for a utility model patent " active controlled engine hydraulic pendant " on September 8th, 2005, its open day is on December 20th, 2006, and publication number is CN2849316Y.This active suspending can well be carried out vibration isolation to high-frequency vibration, but its actuator is connected with counterdie sulfuration, can increase the action rigidity of active engine mount, is unfavorable for vibration isolation; The sulfuration of counterdie and actuator is connected, is the action that will stand upper frequency, therefore vulcanizes joint and is easy to occur sulfuration disengaging and causes leakage, and the vibration of upper frequency also can increase the aging of counterdie; From technology angle, it is extremely difficult that counterdie and actuator are realized to sulfuration is connected, well vulcanizes to be connected to and technically substantially cannot realize.
Model utility content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of active controlled engine hydraulic pendant.
The technical solution adopted in the utility model is such: a kind of active controlled engine hydraulic pendant, comprises the main spring skeleton and the rubber spring that sulfide, and be fixedly installed on the actuator of base inner bottom part; Also comprise decoupling zero film and teleblem; Form lower liquid chamber by decoupling zero film and rubber spring, arrange and form upper liquid chamber by teleblem and rubber spring sulfuration; Between upper liquid chamber and lower liquid chamber, be communicated with by the inertia channel being surrounded by decoupling zero film and rubber spring; The output terminal of actuator is connected with the sulfuration of decoupling zero film.
Further, be connected with at the top of described main spring skeleton the link being connected with motor; On base, be fixedly installed the connecting bolt being connected with vehicle frame.
Further, described actuator is any in electromagnetic actuator, piezoelectric actuator, electro-hydraulic servo actuator and magnetostrictive actuator.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are: the counterdie of prior art is changed into teleblem, has avoided counterdie and actuator sulfuration in prior art to be connected the series of problems bringing, and structure and technique simple.
Accompanying drawing explanation
Fig. 1 is the utility model active controlled engine hydraulic pendant embodiment's longitudinal sectional view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, be a kind of active controlled engine hydraulic pendant embodiment's of the utility model longitudinal construction cross section view.Suspending of this embodiment comprises the main spring skeleton 1 and the rubber spring 2 that sulfide, and is fixedly installed on the actuator 6 of base 3 inner bottom parts, also comprises decoupling zero film 5 and teleblem 8; Form lower liquid chamber by decoupling zero film 5 and rubber spring 2, arrange and form upper liquid chamber with rubber spring 2 sulfurations by teleblem 8; Between upper liquid chamber and lower liquid chamber, be communicated with by the inertia channel 7 being surrounded by decoupling zero film 5 and rubber spring 2; The output terminal of actuator 6 is connected with 5 sulfurations of decoupling zero film.Described teleblem 8 is made up of elastic material, for example, can make for rubber material.
Upper liquid chamber and lower liquid chamber are communicated with by inertia channel, and liquid flows between two liquid chambers, realizes the effect of vibration isolation.In the time that vibration frequency is larger, actuator forms identical with vibration frequency, and Oscillation Amplitude is offset in the action that waveform is contrary, realizes the object of isolation high frequency vibration.Change counterdie into teleblem, avoided counterdie and actuator in prior art to vulcanize the series of problems bringing.
In the present embodiment, as optimal way: be connected with the link 4 being connected with motor at the top of described main spring skeleton 1, be fixedly installed the connecting bolt 9 being connected with vehicle frame on base 3.
In the present embodiment, as optimal way: described actuator 6 is any in electromagnetic actuator, piezoelectric actuator, electro-hydraulic servo actuator and magnetostrictive actuator, preferably adopts electromagnetic actuator.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
