The hydraulic pressure Anti-torque pull rod of the present embodiment, in existing Anti-torque pull rod an one rubber bushing hydraulic bushing (i.e. the first lining 1) is replaced, except working in the displacement of control motor car engine, also have the little amplitude of high frequency that motor of isolating and decay transmits concurrently, the effect of low frequency large-amplitude vibration.The working principle of the hydraulic pressure Anti-torque pull rod of the present embodiment is below described.
Bear the high frequency that motor transmits, little amplitude vibration time, because the inertia of runner internal damping liquid is very large, almost have little time flowing, at this time decoupling zero dish 12 just can to-and-fro motion in the second runner 112.When decoupling zero dish 12 moves toward the first sap cavity 101, now the first sap cavity 101 volume reduces, and the second sap cavity 102 volume increases, and damping fluid flows to the second sap cavity 102 by the second runner 112 from the first sap cavity 101 and realizes compensating.Otherwise when decoupling zero dish 12 moves toward the second sap cavity 102, now the second sap cavity 102 volume reduces, and the first sap cavity 101 volume increases, and damping fluid flows to the first sap cavity 101 by the second runner 112 from the second sap cavity 102.The process Absorbable rod vibrational energy that damping fluid flows back and forth between runner and sap cavity.External effects embody and are, the dither rigidity of the first lining 1 effectively reduces, and eliminate the dynamic hardening effect of high frequency of full rubber bushing, have effectively isolated the vibration of the high frequency that motor car engine transmits, little amplitude.
Bear low frequency that motor transmits, large amplitude vibration time, when the first body of rubber 11 is moved to the second sap cavity 102, damping fluid flow to the first sap cavity 101 from the second sap cavity 102 by first flow 111, due to the second sap cavity 102 pressurized, decoupling zero dish 12 is subject to differential pressure action and moves toward the first sap cavity 101, until the seal disc 121 of decoupling zero dish 12 and the first body of rubber 11 fit tightly, seal up the opening of the second runner 112 at the second sap cavity 102, now damping fluid can not be flowed by the second runner 112 again, is only flowed by first flow 111.Otherwise, when the first body of rubber 11 is moved to the first sap cavity 101, damping fluid flow to the second sap cavity 102 from the first sap cavity 101 by first flow 111, due to the first sap cavity 101 pressurized, decoupling zero dish 12 is subject to differential pressure action and moves toward the second sap cavity 102, until the seal disc 121 of decoupling zero dish 12 and the first body of rubber 11 fit tightly, seals up the opening of the second runner 112 at the first sap cavity 101, now damping fluid can not be flowed by the second runner 112 again, is only flowed by first flow 111.Damping fluid produces large damping by first flow 111, absorbing vibrational energy, with large-amplitude vibration of decaying.
As from the foregoing, the high frequency that motor car engine of effectively isolating the hydraulic pressure Anti-torque pull rod of the present embodiment transmits, the vibration of little amplitude, can produce again large damping, large rigidity decay motor transmit low frequency, large amplitude vibration, ensure that the noise of vehicle, vibration and sound vibration roughness (Noise, Vibration, Harshness, NVH) performance better.First flow 111 and the second runner 112 can according to different vibration characteristics adjustment length and width.
It should be noted that, be illustrated so that the rubber bushing hydraulic bushing of in existing Anti-torque pull rod (i.e. the first lining 1) is substituted by example above, in fact, the equal available hydraulic lining of two rubber bushings in existing Anti-torque pull rod replaces, namely the second lining 2 also can be similarly hydraulic bushing, has the structure identical with the first lining 1.As shown in Figure 7, second lining 2 comprises the second fuse 20, second body of rubber 21 of coated second fuse 20, and the second decoupling zero dish 22, second body of rubber 21 is positioned at the second accommodation section 32 and the second accommodation section 32 is separated into the 3rd sap cavity 201 and the 4th sap cavity 202, second body of rubber 21 is being provided with the 3rd runner 211 away from the second fuse 20 place, second body of rubber 21 is being provided with the 4th runner 212 near the second fuse 20 place, second decoupling zero dish 22 is arranged at the 4th runner 212 and can along the 4th runner 212 to-and-fro motion, 3rd runner 211 and the 4th runner 212 are all communicated with the 3rd sap cavity 201 and the 4th sap cavity 202.When the first lining 1 and the second lining 2 are hydraulic bushing, its principle in the isolation little amplitude of high frequency that transmits of motor car engine and low frequency large-amplitude vibration is identical, repeats no more herein.
Corresponding to the hydraulic pressure Anti-torque pull rod of the embodiment of the present invention one, the embodiment of the present invention two provides a kind of automobile, there is the hydraulic pressure Anti-torque pull rod described in the embodiment of the present invention one, wherein, the external diameter of the first lining 1 is greater than the external diameter of the second lining 2, first lining 1 is connected with motor car engine end, and the second lining 2 is connected with automotive body end or Automobile frame end.The structure and working principle of this hydraulic pressure Anti-torque pull rod refers to the explanation of the embodiment of the present invention one, also repeats no more herein.
Hydraulic pressure Anti-torque pull rod of the present invention is using the lining of hydraulic bushing as pull bar skeleton one end or two ends, except controlling motor car engine displacement, the Anti-torque pull rod comparing existing full rubber bushing in the isolation of the little amplitude of high frequency, low frequency large-amplitude vibration is more effective, ensure that vehicle NVH performance better.In addition, pull bar skeleton adopts nylon material, and weight is little, and cost is low.
