Engine Mounting Structure of Activ Self-Control Type
[13] BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine mounting structure for supporting an engine of a vehicle, and more particularly to an active self-regulating engine mounting structure configured to effectively isolate vibrations and noise at high and low rotational speeds of an engine.
[14] The engine support device, which is generally an engine mounting, has a structure that can withstand the weight of the engine while alleviating and absorbing noise and vibration generated from a running engine, and the type, chassis, etc. of the support position, number, and structure. Various types are adopted in consideration of the structure of the body, among which, the Hydraulic Engine Mounting structure supports the engine of the vehicle and insulates the noise and vibration transmitted and introduced from the engine to the interior of the vehicle. For this purpose, the upper body 103 is fixed to the engine as shown in FIG. 3, and is a portion directly receiving vibration, noise, and torque generated from the engine. The torque transmitted to the upper body 103 applies a load to the fluid in the first liquid chamber 102 inside the mounting, and the second liquid chamber 104 in the lower body 105 is the first liquid chamber 102. It is delivered through the orifice 109 between the and the second liquid chamber 104. The fluid passed by attenuating the orifice 109 due to the pressure difference between the two liquid chambers passes through the upper and lower liquid chambers 102 and 104. Vibration is reduced while flowing.
[15] However, the engine mounting structure of the related art has a structure in which noise and vibration insulation rapidly decrease when a large torque is applied as the engine speed of the vehicle increases. That is, in the high frequency region, the vibration coefficient decreases due to the increase of the dynamic spring constant. There was a problem.
[16] Accordingly, the present invention has been invented to solve the above conventional problems, active self-control type having an excellent dustproof effect by having a magnetic generating device that effectively isolates noise and vibration in a wide range of high and low speed of the engine The purpose is to provide an engine mounting structure.

[17] In order to achieve the above object, the present invention provides an engine mounting structure including an upper body having an insulator, a first liquid chamber, and a lower body having a second liquid chamber, wherein a hole is formed in the center between the first liquid chamber and the second liquid chamber. And an upper plate having circular protrusions formed on an inner circumferential surface thereof, and a lower plate having a plurality of orifices inward and outwardly spaced downward from the upper plate, and a movable plate having upper and lower orifices below the second liquid chamber. The movable plate is partitioned so that the third liquid chamber communicates with the second liquid chamber via the upper and lower orifices.
[18] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
[19] 1 is a cross-sectional view showing an active self-regulating engine mounting structure according to the present invention, Figure 2 is a block diagram of a magnetic field supply generating unit for selectively opening and closing the orifices of the lower plate provided between the first liquid chamber and the second liquid chamber.
[20] The present invention consists of an upper body 3 having an insulator 1 and a first liquid chamber 2 and a lower body 5 having a second liquid chamber 4 as shown in the drawings. (4) In the engine mounting structure in which fluid is filled, the upper plate (8) having a central hole (6) between the first liquid chamber (2) and the second liquid chamber (4) and circular protrusions (7) formed on an inner circumferential surface thereof; The upper plate 8 is mounted with a lower plate 10 having a plurality of orifices 9a and 9b spaced inwardly and outwardly spaced downwardly, and upper and lower orifices 11a and 11b below the second liquid chamber 4. The movable plate 12 provided with this is mounted, The 3rd liquid chamber 13 is formed spaced apart from the 2nd liquid chamber 4 by making this movable plate 12 into a partition.
[21] The third liquid chamber 13 and the second liquid chamber 4 communicate with each other through the upper and lower orifices 11a and 11b of the movable plate 12, and the first liquid chamber 2 and the second liquid chamber 4 are The inner and outer orifices 9a and 9b of the lower plate 10 communicate with each other through the central hole 6 of the upper plate 8.
[22] Meanwhile, as shown in FIG. 2, the wires 15 of the magnetic field generating device 14 are respectively disposed on the upper plate 8 and the lower plate 10 installed between the first liquid chamber 2 and the second liquid chamber 4. It is connected so that the magnetic force of these upper and lower plates 8 and 10 may be generated.
[23] Next, the operation of the present invention, first, at the low speed of the engine, the working torque of the engine is applied to the fluid of the first liquid chamber 2 and the second liquid chamber 4 through the rubber insulator (1), At this time, since the circular projection 7 of the upper plate 8 is grounded with the outer orifice 116 of the lower plate 10, no magnetic force is generated by the magnetic field generating device 14.
[24] Subsequently, the fluid in the first liquid chamber 2 and the second liquid chamber 4 is transferred to the third liquid chamber 13 through the upper and lower orifices 11a and 11b of the movable plate 12 under load. When the fluid is transferred to the third liquid chamber 13 through the upper and lower orifices 11a and 11b of the plate 12, the damping effect is exerted by the pressure difference of the fluid.
[25] On the other hand, the torque transmitted from the engine is increased at the high speed of the engine, as the engine mounting acts as in the low speed region described above, causing a change in the operation of the fluid. That is, as the "+" magnetic field is supplied to the upper plate 8 and the lower plate 10 connected to the magnetic field supply device 14, the upper and lower plates 8 and 10 which are grounded to each other are pushed together by the same magnetic field. .
[26] The circular projection 7 of the upper plate 8 is then spaced apart from the outer orifice 116 of the lower plate 10 to open the outer orifice 116.
[27] Therefore, the fluid in the first liquid chamber 2 supplies more fluid to the second liquid chamber 4 through the enlarged conduit, and the fluid in the second liquid chamber 4 is relatively large to the third liquid chamber 13. By supplying a positive fluid, a high damping function is obtained.
[28] The active self-regulating engine mounting structure according to the present invention as described above is effective to attenuate vibration and noise at both high and low rotational speeds of the engine, thereby obtaining a good dustproof effect.
