Abstract
The invention discloses an active control type engine hydraulic suspension, and belongs to the field of parts for automobile shock absorption. The hydraulic suspension comprises a main spring framework, a rubber main spring and an actuator, wherein the main spring framework and the rubber main spring are combined together through sulfuration, and the actuator is fixedly arranged on the bottom inside the base. The active control type engine hydraulic suspension further comprises a decoupling film and a top film. The decoupling film and the rubber main spring form a lower hydraulic chamber, the top film and the rubber main spring form an upper hydraulic chamber in a sulfuration mode, the upper hydraulic chamber and the lower hydraulic chamber are communicated through an inertia channel defined by the decoupling film and the rubber main spring, and the output end of the actuator is connected with the decoupling film in a sulfuration mode. The active control type engine hydraulic suspension has the advantages that the bottom film in the prior art is changed into the top film, a series of problems caused by the sulfuration connection of the bottom film and the actuator in the prior art are solved, and the active control type engine hydraulic suspension is simple in structure and technology.
Description
Technical field
The present invention 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, raising along with 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, the restriction to liquid fluidity due to 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 patent of invention < < 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, counterdie and actuator are realized to sulfuration and is connected and is extremely difficult, well vulcanize to be connected to and technically substantially cannot realize.
Summary of the invention
Goal of the invention of the present invention is: for the problem of above-mentioned existence, provide a kind of active controlled engine hydraulic pendant.
The technical solution used in the present invention is such: a kind of active controlled engine hydraulic pendant, comprise the main spring skeleton and the rubber spring that sulfide, and the actuator that is fixedly installed on base inner bottom part; Also comprise decoupling zero film and teleblem; By decoupling zero film and rubber spring, form lower liquid chamber, by teleblem and rubber spring sulfuration, arrange and form upper liquid chamber; Between upper liquid chamber and lower liquid chamber, by the inertia channel being surrounded by decoupling zero film and rubber spring, be communicated with; The output terminal of actuator is connected with the sulfuration of decoupling zero film.
Further, at the top of described main spring skeleton, be connected with 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 invention has the beneficial effects as follows: 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 active controlled engine hydraulic pendant embodiment's of the present invention longitudinal sectional view.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
In order to make object of the present invention, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, be a kind of active controlled engine hydraulic pendant embodiment's of the present invention longitudinal construction cross section view.Suspending of this embodiment comprises main spring skeleton 1 and the rubber spring 2 sulfiding, and the actuator 6 that is fixedly installed on base 3 inner bottom parts, also comprises decoupling zero film 5 and teleblem 8; By decoupling zero film 5 and rubber spring 2, form down liquid chamber, by teleblem 8, arrange and form upper liquid chamber with rubber spring 2 sulfurations; Between upper liquid chamber and lower liquid chamber, by the inertia channel 7 being surrounded by decoupling zero film 5 and rubber spring 2, be communicated with; The output terminal of actuator 6 is connected with 5 sulfurations of decoupling zero film.Described teleblem 8 is made by 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.When 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 the series of problems that in prior art, counterdie and actuator sulfuration bring.
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 invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
