Embodiment
Below in conjunction with accompanying drawing, provide preferred embodiment of the present invention, to describe technological scheme of the present invention in detail.
The invention provides a kind of barrel type vibration insulation device, it comprises the interior assembly department of a hollow, one is coaxially nested in the outer assembly department of the hollow outside described interior assembly department, and is embedded the some elastic fillers between interior assembly department and outer assembly department, such as being the rubber body of tool stretchability.Barrel type vibration insulation device also includes one group of elastic shock attenuation assembly being placed in elastic filler, and it is whole that elastic shock attenuation assembly and the sulfuration of described elastic filler form a flexible encapsulation.With entering, along the axial direction perpendicular to interior assembly department, in flexible encapsulation integral body, interval is formed with the active chamber of two annulars that communicate, by the two annular runners that are coated on respectively on two annular working chambers, the closed cavity that two active chambers is divided into two annulars, is provided with an inertia channel at water passage surface.Inertia channel connects described two ring-like closed cavities, is perfused with damp liquid in closed cavity, and by annular runner, the damp liquid that is placed in upper and lower closed cavity forms a loop.
Preferably, the interior assembly department of hollow can be a columned inner frame, has mounting hole on inner frame, and outer assembly department can be the metal shell wrapping in outside inner frame, and shell is embedded in the mounting hole of interior assembly department.
Preferably, the runner of two equal-sized semicircular nylon materials of the above-mentioned preferred tool stretchability of annular runner, such as semiorbicular nylon runner.Runner adopts nylon composite to make, and described nylon material not only has certain stretch-proof and fatigue resistance, also has the mechanical property that metallic material possesses.The present invention adopts nylon runner not only can replace existing metallic material, can also reduce the cost of manufacture.
As shown in Figures 1 to 7, elastic shock attenuation assembly skeleton 41 and two outer skeletons that lay respectively at middle skeleton both sides in a ring that is welded on the rigidity on inner frame 2 form.Middle skeleton is coaxially nested with inner frame respectively with two outer skeletons, is provided with groove 21 on inner frame 2, and the middle skeleton 41 of the ring of rigidity is welded on groove 21 places of inner frame 2.On the cirque body of middle skeleton 41, have four round tube holes that are just being listed as, rubber body 3 is by skeleton 41 in these round tube hole parcels.The cavity of two annular closed is separated by the middle skeleton 41 of described rubber body 3 parcels.
The outer skeleton 42 of two covers jointly sulfides and becomes a flexible encapsulation whole 4 with inner frame 2, middle skeleton 41 and rubber body 3.Rubber body 3 is connected with outer wall, middle skeleton 41, the nylon runner 5 of inner frame 2 after sulfuration, direction in the medial axis perpendicular to inner frame 2, nylon runner 5 contacts with rubber body 3, metal shell 1 and has formed two ring-like airtight cavitys that communicate, wherein the periphery of a set of nylon runner also has an inertia channel 6, the passage circulating back and forth for damp liquid 7.This inertia channel 6 connects upper and lower two ring-like closed cavities 8, makes the damp liquid 7 in two closed cavities 8 form a flow cycle by nylon runner 5.
Two cover nylon runners 5 are comprised of equal-sized two semiround body.Two cover nylon runners 5 are formed on the rubber body part of the outer surface of flexible encapsulation whole 4.
Preferably, inertia channel 6 is for being located at a spiral groove on nylon runner 5 surfaces.At the two ends of inertia channel 6, respectively have the guide groove 61 that a water conservancy diversion is used.Two guide grooves 61 on nylon runner 5 are communicated with two ring-like closed cavities.In airtight metal shell 1, under the parcel of the rubber body 3 of vulcanizing, by inertia channel 6, form the flow cycle communicating up and down.
Barrel type vibration insulation device of the present invention can be also a kind of hydraulic bushing for automobile suspension system.
Automobile suspension system take below as example, illustrate that the working principle of barrel type vibration insulation device of the present invention is as follows:
As shown in Figures 1 to 7, two outer skeletons 42, middle skeleton 41, an inner frame 2 and a rubber body 3 are sulfided into a flexible encapsulation whole 4, and forming a hydraulic bushing (being barrel type vibration insulation device of the present invention) with shell 1 encapsulation, the inside of hydraulic bushing pours into damp liquid 7.The vibration passing over from Automobile Shock Absorber, after rubber body 3 vibration isolation of (hereinafter referred to as hydraulic bushing), then is passed to damp liquid 7 dampings.Vibrate in addition after whole hydraulic bushing damping and arrive vehicle body.Hydraulic bushing is realized the isolation to the vibration from road surface by twin-stage vibration isolation.Particularly, that is: when load is by inner frame 2 and middle skeleton 41, the encapsulation integral body 4 of process rubber is delivered on shell 1, because shell 1 is to contact with automobile chassis front arm, so power passes on the mating face of vehicle body.Complete the transmission to the supporting of car load and dynamic load.When road vibration passes to inner frame 2 by cylinder type hydraulic lining, cause the vibration of inner frame 2, after the vibration isolation of the vibration of inner frame 2 by hydraulic bushing and decay, pass to shell 1, after decay, pass to vehicle body.Vibration is after twin-stage vibration isolation like this, and vibration is significantly decayed.
When hydraulic bushing is being subject to low frequency large-amplitude vibration, for roll response, when a roll response power is input to inner frame 2, the volume of two airtight active chambers up and down of hydraulic bushing changes.The pressure that simultaneously produces upper and lower two airtight active chambers changes, impel the damp liquid 7 in upper and lower active chamber just to pass through the inertia channel 6 on nylon runner 5, and follow outside vibration at the interior double vibrations of nylon runner 5, thus absorb outside vibrational energy, play the effect of vibration damping.
Under the inclination excitation of low frequency large amplitude, hydraulic bushing shows large damping, large rigidity, makes car load have better control stability peace and performance like this.And when resonance appears in the vibration of liquid, show large damping and large dynamic stiffness.The inhibition of realization vehicle roll during to high speed steering, thus improve handling.
The power that the intrinsic characteristic of nylon material of nylon runner of the present invention itself can absorb liquid vibration force and produce from the stretching of rubber body or compression, than adopting, hydraulic bushing more reasonable structure, the technique of metal flow passage are also more ripe, effectively reduce product cost.Except providing the function of conventional anti-vibration bush, and can further provide vibration isolating effect, can greatly improve handling simultaneously.
Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, do not deviating under the prerequisite of principle of the present invention and essence, can make various changes or modifications to these mode of executions.Therefore, protection scope of the present invention is limited by appended claims.
