Control gear is for detecting motor and gearbox-gear excited frequency.The rotational frequency that when motor and gearbox-gear excited frequency are Vehicular vibration, motor and gearbox-gear produce.When motor and gearbox-gear excited frequency are less than or equal to setting threshold value, closed control valve, disconnects air hole 10 and air.When motor and gearbox-gear excited frequency are greater than setting threshold value, open control valve, air hole 10 is communicated with air.In the present embodiment, control valve is solenoid valve 9.And setting threshold value is in the scope of 20Hz-30Hz.
Solenoid valve 9 is arranged on air hole 10 with in the communicating passage of outside atmosphere, for controlling the closedown of described communicating passage and opening.Thus determine whether air chamber 14 communicates with air, control the volume rigidity of air chamber 14, and then affect the rigidity of whole semi-actively controlled hydraulic mount, to adapt to the requirement of corresponding operating mode.
Particularly, when motor excited frequency is between 0Hz to 25Hz, air hole 10 is blocked by solenoid valve 9 (namely making described communicating passage close) and make air chamber 14 become closed chamber.When motor excited frequency is greater than 25Hz, air hole 10 is opened by solenoid valve 9 (namely making described communicating passage open) and air chamber 14 is communicated with air.
Fig. 5 is the electromagnetic valve schematic diagram in semi-actively controlled hydraulic mount shown in Fig. 2.
Processing unit 103 gathers engine rotational speed signal and gearbox-gear signal by engine rotation speed sensor 101 and gearbox-gear sensor 102, and this signal is sent to control gear 104.Control gear 104, according to engine rotational speed signal and gearbox-gear signal, detects the excited frequency of motor and gearbox under this operating mode, and sends open command or out code to the solenoid valve 9 of semi-actively controlled hydraulic mount.After receiving instruction, solenoid valve 9 action, and make air hole 10 or the passage that is communicated with air hole 10 is in the state opened or closed, thus control air chamber 14 and whether communicate with air.
Semi-actively controlled hydraulic mount is when motor and gearbox-gear excited frequency are in different frequency, and semi-actively controlled hydraulic mount reaches the detailed process of damping effect:
When excited frequency lower (0Hz < f < 25Hz), amplitude are larger, solenoid valve 9 controls push rod and makes air hole 10 be in closed condition, air chamber 14 volume rigidity is very large, the decoupling zero of activity simultaneously dish is close to the baffle plate of side, liquid is stoped to pass through, liquid can only be flowed between upper liquid chamber 12, lower liquid chamber 13 by inertia channel 5, and significant damping effect is played in the damping that the liquid in inertia channel 5 is produced by linear loss and restriction loss;
As excited frequency higher (f > 25Hz), when amplitude is less, liquid in inertia channel 5 almost no longer flows, produce dynamic hardening phenomenon, now decoupling zero dish unrestricted motion in the certain limit of upper lower pedal, remarkable reduction upper liquid chamber 12, the fluid pressure fluctuation of lower liquid chamber 13, be conducive to the high frequency dynamic stiffness reducing suspension, the generation of anti-dynamic sclerosis, simultaneously solenoid valve 9 controls push rod and makes air hole 10 be in open mode, air chamber 14 communicates with air, (blow-by) volume rigidity is very little, the fluid pressure fluctuation of upper liquid chamber 12 can be reduced further by the elastic vibration of elasticity decoupling zero film 11, thus can obvious attenuating automobile vibration, reduce internal car noise, improve riding comfort.
At high frequencies (f > 100Hz), solenoid valve 9 controls push rod and makes air hole 10 be in open mode, air chamber 14 communicates with air, volume rigidity is very little, elasticity decoupling zero film 11 can easily fluctuate according to the fluid pressure of upper liquid chamber 12 and vibrate, that is, the fluid pressure fluctuation of upper liquid chamber 12 can be reduced further by the elastic vibration of elasticity decoupling zero film 11, therefore there will not be dynamic hardening phenomenon, or significantly improve the frequency occurring dynamically sclerosis, reduce high frequency dynamic stiffness.
