Embodiment 1
[0032] The present application provides an active control hydraulic mount structure, such as Figure 1 to Figure 6 As shown, it includes an upper mounting bolt 1, a metal frame 2, a rubber main spring 3, a suspension housing 4, a suspension bottom case 8, a lower mounting bolt 9, a rubber bottom film 7, an upper baffle 5 and a lower baffle 6, In each embodiment of the present application, the above components of the hydraulic mounting structure are all in the prior art, and the applicant will not describe them in detail here.
[0033] The upper mounting bolt is fixed on the metal skeleton, and the metal skeleton, the rubber main spring and the suspension shell are vulcanized into an integrated structure, which is also the prior art.
[0034] An upper partition plate and a lower partition plate are arranged in the suspension shell, and a rubber bottom film is arranged at the lower end of the suspension shell; However, the upper baffle plate and the lower baffle plate cannot be...
Embodiment 2
[0046] In this embodiment, other structures of the hydraulic mount are the same, and the only difference is the structure of the ring electrode.
[0047] In this embodiment, the ring electrode includes a first ring electrode and a second ring electrode, the first ring electrode is arranged in the upper inertia channel, and the second ring electrode is arranged in the lower inertia channel.
[0048] In this way, after the pressure signal transmitted by the sensor is transmitted to the control board, the magnitude and direction of the current of the corresponding annular electrode can be respectively controlled, which makes the control of the hydraulic mount more flexible.

Abstract
The invention relates to an active control hydraulic suspending structure, comprising an upper installing bolt, a metal framework, a main rubber spring, a suspending shell, a suspending bottom shell, a lower installing bolt, a rubber base film, an upper clapboard, a lower clapboard, a sensor, an annular electrode and a control plate. Through adding the annular electrode on the basis of the traditional suspension, outside pressure is transmitted to the control plate through an electric signal after the sensor judges the outside pressure, and the control plate controls power output according to the pressure change and changes the electro-hydraulic or voltage intensity output to the annular electrode or changes the current direction, thus corresponding annular electrode material is contracted or expanded, so as to change the size of the inside diameter of a corresponding inertia channel, and reach the purpose of changing the suspending rigidity.
Description
technical field [0001] The invention belongs to the technical field of engine mounts, in particular to an active control hydraulic mount structure. Background technique [0002] The car engine is arranged on the chassis, and the frame and the engine are connected through the engine suspension cushion; the engine cushion must have the function of attenuating engine vibration and ensuring that the engine displacement does not exceed the design allowable range while supporting the engine. [0003] The traditional suspension cushion is composed of rubber main spring, inertia channel, decoupling diaphragm, throttle disc, connecting bolt and rubber bottom diaphragm. When the suspension is excited by low frequency and large amount, the displacement amplitude of the decoupling diaphragm is larger, reaching its upper limit and lower limit position, the liquid mainly flows between the upper liquid chamber and the lower liquid chamber through the inertial channel, resulting in a large ...
