Embodiment
Content of the present invention is described below in conjunction with specific embodiments.
As depicted in figs. 1 and 2, be a kind of hydraulic suspension structure of engine schematic diagram of the present invention.A kind of engine hydraulic mount of the present invention, comprise: rubber spring 2, main spring skeleton 3, inertia channel skeleton 5, runner plate 6, decoupling zero diaphragm 7, counterdie 8, described rubber spring 2 bottom edge connect described main spring skeleton 3, described inertia channel skeleton 5 upper ends connect described main spring skeleton 3, described inertia channel skeleton 5 lower ends connect described counterdie 8, described runner plate 6 is provided with inertia channel, and described runner plate 6 is assemblied in described inertia channel skeleton 5, described decoupling zero diaphragm 7 is assemblied on described runner plate 6; Described main spring skeleton 3, inertia channel skeleton 5 and runner plate 6 are polyamide material and make, and the arranged outside of described main spring skeleton 3 has cellular lateral reinforcement structure 31.Described rubber spring 2 also comprises main spring upper bracket 1, and described main spring upper bracket 1 is metal quality.
Sidewall and the counterdie 8 of the bottom surface of described rubber spring 2 and main spring skeleton 3, inertia channel skeleton 5 have formed the liquid chamber 4 for loading liquid jointly, on described inertia channel skeleton 5, runner plate 6 is set, in the time that engine hydraulic mount is subject to the excitation of low frequency, large amplitude, rubber spring 2 can repeat to occur to stretch and the deformation of compressing, thereby the inertia channel that the liquid in liquid chamber 4 is flowed through on runner plate 6 repeatedly, consume the energy of vibration by overcoming the inertia of liquid, thereby realize the object of vibration damping; In the time that engine hydraulic mount is subject to the excitation of high frequency, little amplitude, carry out vibration at high speed and consume vibrational energy by inertia by the decoupling zero diaphragm 7 being assemblied on runner plate 6, under dither, having the deficiency of dynamic sclerosis to make up inertia channel on runner plate 6.Main spring skeleton 3, inertia channel skeleton 5 and runner plate 6 in said structure are selected polyamide material, can under the prerequisite that ensures mechanical strength, reduce cost of material on the one hand, can reduce on the other hand the overall weight of engine hydraulic mount, in addition, the injection molding of plastic components is than the casting of metalwork with sheetmetal working cost is low, speed is fast.
But, not in engine hydraulic mount, all metal partss can simply replace with polyamide material, the effect of main spring upper bracket 1 and main spring skeleton 3 is to make up the deficiency of rubber spring 2 rigidity, ensure the shape of rubber spring 2, and improve the quiet rigidity of side direction of hydraulic mount, for improving the internal stress distribution of rubber spring 2, avoid stress to concentrate in addition.Therefore, the present invention selects main spring upper bracket 1 to keep original metal quality and Structural Hardware, and main spring skeleton 3 is replaced with to polyamide material, and in order to ensure that the main spring skeleton 3 that polyamide material is made has function and the effect that master metal spring skeleton 3 is identical, in the arranged outside of the main spring skeleton 3 of polyamide cellular lateral reinforcement structure, be applied on automobile thereby make engine hydraulic mount of the present invention can replace well traditional metal hydraulic to suspend.Main spring upper bracket 1 keeps original metal quality and Structural Hardware, to have considered to replace to the required design cost of polyamide material and product testing success rate, because the consumption that simply increases polyamide material no doubt can be realized the rigidity requirement of main spring upper bracket 1, but can cause materials cost to go up not down, and can increase the volume of main spring upper bracket 1, cause assembling difficulty, maybe need to change the design of corresponding automobile assembling parts; In fact, in replacing with polyamide material, also all there is similar above-mentioned problem for main spring skeleton 3, inertia channel skeleton 5 and runner plate 6, grope by test of many times, design modular construction or assembly structure as illustrated in fig. 1 and 2, just finally realize the lightweight of engine hydraulic mount, adopt preferred polyamide material, structure reasonable in design, thereby make part parts plastics replace metal as raw material.

Second step: main spring upper bracket 1, main spring skeleton 3 are placed in to rubber mold, inject rubber sulfidization molding and make rubber spring 2;
The 3rd step: adopt rotary welding machine to be connected and fixed main spring skeleton 3 and inertia channel skeleton 5.
In order to load liquid, need to form the liquid chamber 4 of sealing, it is comparatively novel and advanced that engine hydraulic mount provided by the present invention forms the moulding process of sealing liquid chamber 4: be to be welded and formed the liquid chamber 4 sealing by the high pressure between main spring skeleton 3 and inertia channel skeleton 5, the high rotating speed heat fusing that rub, this moulding process is stable and to almost zero wearing and tearing of frock, single product molding time is short, so just realize production cycle shortening, thereby improved the productivity of product; Particularly, described rotary welding machine can be for must believe SW300 rotary welding machine, and maximum speed can reach 1000 RPM, and pressure maximum can reach 500 KP.
There are a lot of abnormal conditions in the early development of this kind of spin friction welding procedure above, for example, due to the welding amalgamation of working of plastics material itself and the design irrationality of welding equipment parameter, can not meet the demands and occur that welding slag after phenomenon and the welding of product leakage is excessive and cause stopping up the phenomenon of inertia channel mouth; So finally two of this production debugging problems have just been presented, and be conflicting between them; Two problem points are respectively: leakage and welding slag are excessive; Just need to strengthen the depth of weld in order to overcome leakage, but the increase of the depth of weld will cause welding slag excessive; Finally we have passed through test and the detection validation of a lot of wheels, find solution: i.e. the polyhexamethylene adipamide containing 30% glass fibre in the making material preferred polyamide of described main spring skeleton 3 and inertia channel skeleton 5, the process conditions of spin welding are: rotating speed is that 1000 ± 50 RPM, pressure are that 330 ± 20 KPa, the depth of weld are 3.8 ± 0.2 mm.Adopt above-mentioned process conditions, the welding slag of molten state can be evenly distributed in one week of welding main body, and there will not be the problem of leakage.
