Description
Technical Field
The invention relates to the field of hydraulic suspension, in particular to a hydraulic suspension of an automobile engine.
Background
The hydraulic suspension is used for engine vibration reduction, it generally includes shell, rubber main spring, inertia channel body, die block etc. rubber main spring is fixed in shell upper portion, and rubber main spring is connected with the engine, the shell is inside to be filled to have hydraulic medium, the inertia channel body is fixed in the shell inside, divide into upper and lower two parts with the shell inside by the inertia channel body, the inertia channel body intermediate position is equipped with the decoupling zero passageway, upper and lower part of decoupling zero passageway respectively through the intercommunication mouth correspondence with the upper and lower part in the shell respectively, be equipped with the decoupling zero in the decoupling zero passageway, the decoupling zero is the level and cuts apart the decoupling zero passageway from top to bottom, there is the space between decoupling zero border and the decoupling zero passageway inner wall, still be equipped with the inertia channel in the inertia channel body, the inertia channel communicates with the upper and lower two parts in the shell respectively.
The working process of the hydraulic suspension in the prior art is as follows: when the engine generates low-amplitude or high-amplitude vibration, the volume of the upper part of the space in the housing between the rubber main spring and the inertia passage body is compressed or stretched, and thus the hydraulic pressure of the upper part of the housing increases or decreases along with the change of the volume. When in low-amplitude vibration, the inertia channel is self-locking (the blocking effect of the inertia channel is larger than the hydraulic pressure entering the inertia channel under the low-amplitude vibration and is equivalent to the self-locking of the inertia channel), and the hydraulic medium mainly flows from the gap between the inner wall of the decoupling channel and the edge of the decoupling disc; when the space of the upper part in the shell is compressed and the hydraulic pressure is increased, the hydraulic medium corresponding to the compressed volume of the upper part in the shell enters the decoupling channel and enters the lower part in the shell through the decoupling channel, and simultaneously the decoupling disc moves downwards. When the space of the upper part in the shell is stretched and the hydraulic pressure is reduced, the hydraulic medium of the lower part in the shell enters the decoupling channel and enters the upper part in the shell through the decoupling channel to fill the stretched volume of the upper part in the shell, and simultaneously, the decoupling disc moves upwards. The up-and-down motion of the decoupling disc is utilized to lead the liquid pressure of the upper part and the lower part in the shell to quickly tend to balance, thereby realizing the damping and vibration reduction function.
When the high-amplitude vibration is carried out, the up-and-down motion of the decoupling disc can reach the limit position, namely, the upper communication port of the decoupling channel is blocked when the decoupling disc moves upwards to the upper limit position, the lower communication port of the decoupling channel is blocked when the decoupling disc moves downwards to the lower limit position, when the communication port is blocked, the decoupling channel is closed, the hydraulic medium can only flow in the upper part and the lower part in the shell through the inertia channel under the hydraulic action, and the damping and vibration reduction function is realized through the blocking effect of the inertia channel on the flowing medium.
It can be seen from the prior art hydraulic suspension working process that during high amplitude vibration, although the decoupling disc can move to the limit position to close the decoupling channel, so that the flowing medium passes through the inertia channel, the decoupling disc cannot be kept fixed at the limit position, and therefore the inertia channel is not completely matched with the flowing medium to play a damping and vibration reducing role during high amplitude vibration. And, when vibrating by a low margin, the up-and-down motion of decoupling disc is suitable for the upper and lower partial hydraulic pressure variation in the shell, can't initiatively adjust the up-and-down motion of decoupling disc.

The control system comprises a controller, a controllable power supply and a controllable switch, wherein the controllable power supply is in power supply connection with the annular electromagnet through the controllable switch, the amplitude detection unit is in signal transmission connection with the controller, and the controller is respectively in control connection with the controllable power supply and the controllable switch;
The controller is internally provided with a first amplitude threshold value and a second amplitude threshold value, wherein the second amplitude threshold value is smaller than the first amplitude threshold value; the controller compares the data acquired by the amplitude detection unit with a first amplitude threshold value and a second amplitude threshold value respectively, wherein:
if the acquired data is smaller than or equal to the second amplitude threshold value, the controller controls the controllable switch to be switched off, so that the annular electromagnet does not generate magnetic attraction;
if the acquired data is smaller than the first amplitude threshold value and larger than the second amplitude threshold value, the controller controls the controllable switch to be turned on, and simultaneously controls the controllable power supply to output variable voltage or current, so that the annular electromagnet generates variable magnetic attraction force to be applied to the decoupling disc;
If the acquired data is greater than or equal to the first amplitude threshold value, the controller controls the controllable switch to be turned on, and simultaneously controls the controllable power supply to output constant voltage or current, so that the annular electromagnet generates constant magnetic attraction to adsorb and fix the decoupling disc.

In the decoupling channel, the electromagnet is fixedly arranged at the outer ring of the communication position of the communication port and the decoupling channel, the decoupling disc is fixedly provided with the magnetic attraction body, the electromagnet generates magnetic attraction force capable of acting on the decoupling disc in the electrified state, and the motion state of the decoupling disc can be interfered by the magnetic attraction force.
Under high-amplitude vibration, the electromagnet can generate enough invariable magnetic attraction to adsorb and fix the decoupling disc, so that the decoupling disc blocks the corresponding communication port and the decoupling channel is closed, and therefore, under high-amplitude vibration, a hydraulic medium cannot pass through the decoupling channel and can only flow through the upper part and the lower part in the shell through the inertia channel. By the mode, the damping vibration reduction effect during high-amplitude vibration can be improved.

Compared with the prior art, the invention has the advantages that: the invention can interfere the motion state of the decoupling disc by applying the electromagnetic force to the decoupling disc, thereby improving the damping vibration reduction effect of the hydraulic suspension when vibrating in high amplitude and low amplitude.

Description of the embodiments
The invention will be further described with reference to the drawings and examples.
As shown in fig. 1, a hydraulic suspension of an automobile engine comprises a shell 1, wherein a rubber main spring 2 is connected to the upper part of the shell 1. The inner wall of the shell 1 is provided with a platform 3 corresponding to the bottom of the rubber main spring 2, the top surface of the platform 3 is embedded and provided with a piezoelectric ceramic piece 4, and the corresponding position of the bottom of the rubber main spring 2 is fixed at the position of the piezoelectric ceramic piece 4 of the platform 3. When vibration occurs, the rubber main spring 2 is also pressed or stretched along the table 3 of the shell 1, so that the piezoelectric ceramic plate 4 generates a corresponding electric signal, the electric signal is related to the amplitude, and the amplitude can be known through the electric signal generated by the piezoelectric ceramic plate 4. Thus, the piezoelectric ceramic sheet 4 functions as an amplitude detection means.
The shell 1 is filled with hydraulic oil, an inertia passage body 5 is fixed in the shell 1, the interior of the shell 1 is divided into an upper part and a lower part by the inertia passage body 5, and a bottom film 6 for sealing the inner bottom of the shell 1 is fixed in the shell 1 at a position below the inertia passage body 5. An inertia passage 14 is arranged in the inertia passage body 5, and the inertia passage 14 is communicated with the upper part and the lower part in the shell 1.

The decoupling disc 9 is arranged in the decoupling channel 7, the decoupling disc 9 is horizontal, and a gap is reserved between the edge of the decoupling disc 9 and the inner wall of the decoupling channel 7. Thereby, the hydraulic oil can flow between the upper and lower parts in the housing 1 through the upper and lower communication ports 8.1, 8.2 and the space between the decoupling disc 9 and the decoupling passage 7.
In the decoupling channel 7, an annular electromagnet 10 is fixedly arranged on the outer ring of the communication position of the integral communication port and the decoupling channel, the inner ring of the annular electromagnet 10 surrounds the outer ring of the communication position of the corresponding communication port, and one magnetic pole surface of the annular electromagnet 10 faces the decoupling disc 9. A plurality of through holes are arranged on the circumference of the decoupling disc 9 corresponding to the annular electromagnet 10, and a magnetic attraction body 11 is respectively embedded and fixed in each through hole. When the annular electromagnet 10 is electrified to generate magnetic attraction force, each magnetic attraction body 11 can be magnetically attracted, so that the whole decoupling disc 9 is magnetically attracted.
In the invention, the annular electromagnet 10 can be only fixed outside the communication position of the upper communication port 8.1 and the decoupling passage in a surrounding manner, and can also be only fixed outside the communication position of the lower communication port 8.2 and the decoupling passage in a surrounding manner. The invention can also be two annular electromagnets which are respectively fixed outside the communication position of the upper communication port 8.1 and the decoupling channel and outside the communication position of the lower communication port 8.2 and the decoupling channel in a surrounding way. No matter where the ring electromagnet 10 is located, it is only necessary to ensure that each magnetic attraction body 11 of the decoupling disc 9 can be magnetically attracted.
In the invention, in order to ensure stable up-and-down movement of the decoupling disc 9, a guide post 12 is fixed between the middle positions of the top and the bottom in the decoupling channel 7, and the decoupling disc 9 is slidably mounted on the guide post 12 through a central guide through hole. In order to ensure that the decoupling disc 9 cannot rotate, the section of the guide post 12 can be designed to be non-circular, and the central guide through hole of the decoupling disc 9 can be designed to be in a matched shape.
The invention also includes a control system 13, shown in fig. 2, comprising a controller, a controllable power supply, a controllable switch. Wherein:
The controller can adopt the self controller ECU of the automobile, and the annular electromagnet 10 adopts a direct current electromagnet, so that a controllable power supply adopts a controllable direct current power supply, and a controllable switch adopts a high-frequency switch.

When the controller receives the electrical signal generated by the piezoelectric ceramic plate 4, it converts it into an amplitude value, and compares the amplitude value with a first amplitude threshold value and a second amplitude threshold value, respectively.
If the acquired amplitude value is smaller than or equal to the second amplitude threshold value, the hydraulic suspension is in a low-amplitude vibration state, the amplitude is smaller, and the hydraulic suspension can completely realize damping vibration reduction by means of the adaptive up-and-down movement of the decoupling disc 9. At this time, the controller controls the controllable switch to be turned off, so that the annular electromagnet 10 does not generate magnetic attraction, and therefore, damping vibration attenuation is realized only by means of the adaptive up-and-down movement of the decoupling disc 9 according to the working principle of the traditional hydraulic suspension.
If the acquired amplitude value is smaller than the first amplitude threshold value and larger than the second amplitude threshold value, the amplitude value is increased, and the hydraulic suspension is in a low-amplitude vibration state at the moment. At this time, the controller controls the controllable switch to be turned on, and simultaneously controls the controllable power supply to output variable voltage or current, so that the annular electromagnet 10 generates variable magnetic attraction force to be applied to the decoupling disc 9, and further the up-and-down motion of the decoupling disc 9 is interfered, and active adjustment of the up-and-down motion of the decoupling disc 9 is realized, so that the damping and vibration reduction capability is improved.
And if the acquired amplitude value is greater than or equal to the first amplitude threshold value, indicating that the hydraulic mount is in a high-amplitude vibration state at the moment. At this time, the controller controls the controllable switch to be turned on, and simultaneously controls the controllable power supply to output a fixed and invariable larger voltage or current, so that the annular electromagnet 10 generates a invariable larger magnetic attraction force which is larger than the maximum value of the difference between the upper part hydraulic pressure and the lower part hydraulic pressure in the shell 1 when the annular electromagnet 10 vibrates in a theoretical high amplitude, and when the decoupling disc 9 moves to the position of the annular electromagnet 10, the decoupling disc 9 is fixedly adsorbed by the annular electromagnet 10, so that the decoupling channel 7 is closed, hydraulic oil can only flow through the inertia channel 14, and therefore the damping and vibration reducing capacity is improved.
