Embodiment
Below in conjunction with accompanying drawing invention is described further:
Referring to Fig. 2, the utility model is made up of small end rubber shock-absorbing assembly 4, main spring bracket assembly 5, orifice union 6 and leather cup assembly 7.The utility model is a monolithic construction, and small end rubber shock-absorbing assembly 4 is connected with power assembly, and main spring bracket assembly 5 is connected with vehicle body.
Referring to Fig. 5, small end rubber shock-absorbing assembly 4 is formed by outer tube 8, vibration isolation rubber 9 and the 10 whole sulfurations of interior pipe.
Participate in Fig. 3, main spring bracket assembly 5 by stake body 11, U type runner plate 12, core pipe 13 and rubber spring 14 be sulfided into one.Stake body 11 is the little hollow elongate member of the big end of an end, and its small end has the mounting hole of small end rubber shock-absorbing assembly 4, and big end sulfuration is provided with U type runner plate 12 and rubber spring 14.Core pipe 13 is positioned at rubber spring 14 centers, is sulfided into one; Described U type runner plate 12 semi-surroundings are sulfided into one outside rubber spring 14.11 of U type runner plate 12 and stake bodies are provided with the U type runner 15 of sealing up and down.Lean on stake body 11 big end one sides and the stake bodies 11 of rubber spring 14 are surrounded by liquid chamber 16 jointly, and be pressed into stake body 11 with liquid chamber 16 sealings from the lateral openings of stake body 11 big ends by orifice union 6 and leather cup assembly 7, referring to Fig. 4, described orifice union 6 is liquid chamber 17 and back liquid chamber 18 before the centre is separated into liquid chamber 16, two ends by U type runner 15 between the liquid chamber of front and back are communicated with, and in the described liquid chamber 16 damp liquid are housed.
Referring to Fig. 6 and Fig. 7, orifice union 6 is made up of throttling sheet 19 therebetween rubber decoupling zero sheets 20, leaves throttle clearance between throttling sheet 19 and the decoupling zero sheet 20, and throttling sheet 19 and decoupling zero sheet (20) are provided with the throttle orifice 21 that staggers mutually.
Referring to Fig. 8 and Fig. 9, U type runner plate 12 whole U-shapeds, the cross section is the plate structure that the punching press convex tendon is arranged.
The action principle of this device is as follows:
When power assembly produced vibrational excitation, vibration at first passed to small end rubber damping assembly 4, and is subjected to the one-level vibration damping at this.Vibrate then from small end rubber damping assembly 4 and pass to main spring bracket assembly 5, and be subjected to the secondary vibration damping herein.Because of the core pipe 5 in the main spring bracket assembly 5 is connected motionlessly with body side, when stake body 11 is vibrated, the rubber spring 14 that sulfides with it will deform, thereby liquid chamber 17 volumes change before causing, cause damp liquid play between the liquid chamber of front and back.For low frequency large amplitude twisting excitation, the pressure difference between the liquid chamber of front and back is bigger, causes 20 distortion of rubber decoupling zero sheet bigger, has closed the throttle orifice 21 on the orifice union 6, and damp liquid can only pass through U type passage 15 play between the liquid chamber of front and back.Owing to damp liquid through thin long U type runner 15, so the utility model can provide big rigidity and the damping low frequency large-amplitude vibration of decaying greatly.For the little amplitude torsional excitation of high frequency,, cause 20 distortion of rubber decoupling zero sheet very little because the pressure reduction of front and back liquid chamber is less.So the throttle orifice 21 on the orifice union 6 is an opening state.Damp liquid is directly by throttle orifice 21 play back and forth between the liquid chamber of front and back.The throttle orifice 21 of flowing through and lacking greatly owing to damp liquid is so the utility model can provide little rigidity and little damping to come the attenuate high frequency small amplitude motion.
Protection domain of the present utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not break away from scope and spirit of the present utility model the utility model.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, intention then of the present utility model also comprises these changes and is out of shape interior.
