The defects of the hydraulic suspension are not improved in the aspect of damping performance, and the problem that the hydraulic suspension is easy to leak liquid is not mentioned.
Disclosure of Invention
The invention overcomes the defects of poor vibration damping effect, low vibration damping response speed, poor sealing effect and easy liquid leakage of the existing hydraulic suspension, and provides the hydraulic suspension structure with stronger vibration damping and energy absorbing effects and better sealing performance.
In order to solve the technical problems, the invention is realized by the following technical scheme:
the utility model provides a hydraulic suspension structure, including bottom plate support, main spring rubber, go up sap cavity and lower sap cavity from last to arranging in proper order down, main spring rubber is inside include with the opening of last sap cavity intercommunication, be equipped with the sand grip in the opening, sand grip circumference sets up on main spring rubber's inside wall, main spring rubber bottom is equipped with first annular groove, first annular groove arranges on main spring rubber's lateral wall, the reason is equipped with the annular buckle with first annular groove adaptation on the bottom plate support, the annular buckle with first annular groove is interference fit.
The convex strip is additionally arranged on the inner side wall of the main spring rubber, the liquid flowing rule in the upper liquid cavity can be changed, the turbulent flow of fluid in the upper liquid cavity is increased under the turbulent flow effect, and energy loss (the energy comes from the vibration of an engine) is caused, so that the vibration reduction and energy absorption effects are better, and more energy can be absorbed than the existing hydraulic suspension.
On the other hand, the hydraulic suspension needs to ensure that the liquid in the hydraulic suspension flows only among the main spring rubber, the upper liquid cavity and the lower liquid cavity, so that the hydraulic suspension has higher requirements on the tightness. Liquid leaks out from the gap between upper fluid chamber and the lower fluid chamber easily among the current hydraulic suspension, and the liquid that plays the damping action among the hydraulic suspension will run off then, leads to the hydraulic suspension effect to worsen. According to the invention, the annular buckle structure is arranged on the bottom plate bracket, so that the bottom plate bracket and the main spring rubber are hooped together, and the buckle is annular, which means that the circle of the outer side wall of the main spring rubber is wrapped and locked by the bottom plate bracket. And annular buckle and the first annular groove interference fit of main spring rubber can effectively strengthen the main spring rubber of top and the laminating of bottom plate support of below.
Preferably, a decoupling disc is arranged between the upper liquid cavity and the lower liquid cavity, a decoupling film is arranged in the decoupling disc, and a plurality of convex columns fixed on the inner wall of the decoupling disc are arranged between the decoupling disc and the decoupling film. The hydraulic pressure suspension is at the working process, and decoupling zero membrane meeting up-and-down motion and decoupling zero dish bump, bring the big problem of noise, sets up a plurality of projections at decoupling zero dish inner wall, and the suggestion adopts the rubber material, can alleviate the noise that decoupling zero membrane and decoupling zero dish bump brought.
Preferably, the lower diaphragm is bowl-shaped, the lower diaphragm and the decoupling disc form a lower liquid cavity, a vertically arranged rotating spring is arranged between the lower diaphragm and the decoupling disc, a transverse partition plate is arranged in the middle of the rotating spring, and when the rotating spring is compressed, the partition plate rotates by taking the spring as an axis. The existing decoupling disc is generally provided with a through hole, and the aforementioned rotating spring is arranged between the lower diaphragm and the decoupling film, namely, one end of the rotating spring passes through the through hole of the decoupling disc (generally, a plurality of decoupling holes are formed in the decoupling disc, namely, the through hole mentioned here) to be connected with the decoupling film, and the other end of the rotating spring is connected with the lower diaphragm. When the hydraulic suspension works, the decoupling film moves up and down. The decoupling film moves downwards, so that when the rotating spring is compressed, the rotating spring can rotate, and the partition plate is driven to rotate in the horizontal direction by taking the spring as an axis; then the decoupling film moves upwards, so that the rotating spring returns to the original state and drives the partition plate to rotate in the opposite direction. In the rotating process of the partition plate, the function of stirring liquid in the lower liquid cavity can be achieved, the liquid is accelerated to flow between the lower liquid cavity and the upper liquid cavity through the inertia channel (the inertia channel belongs to the prior art, and details are not repeated here), and the response speed of the hydraulic suspension during vibration reduction is increased.

When the hydraulic suspension works, the decoupling film moves downwards to compress the space of the lower liquid cavity, the rotating spring contracts simultaneously, the first partition plate and the second partition plate stir the liquid in the lower liquid cavity to urge the liquid in the lower liquid cavity to flow into the upper liquid cavity, and vibration reduction and energy absorption are realized more quickly; then, the decoupling film moves upwards, the volume of the upper liquid cavity is reduced, liquid in the upper liquid cavity flows back to the lower liquid cavity, the first partition plate and the second partition plate rotate in the opposite directions after the rotating spring contracts, then the first partition plate and the second partition plate are attached to each other to form a plate with a larger cross section, and the plate can play a role in preventing liquid in the lower liquid cavity from generating turbulence. Because the decoupling film can reciprocate up and down and stops when not completing one up-and-down movement, in order to enable the decoupling film to move up again, the liquid in the lower liquid cavity can also flow into the upper liquid cavity quickly, and the first partition plate and the second partition plate are combined to reduce the turbulent flow of the lower liquid cavity.
Preferably, the cross sections of the first partition plate and the second partition plate are respectively in the shape of a yin-yang fish. When the rotating spring is relaxed, the first partition plate and the second partition plate can be combined into a Taiji shape like a male fish and a female fish, so that the whole cross section is circular, and the cross section of the lower liquid cavity is also circular, so that the design of the first partition plate and the second partition plate is effective for balancing the flow velocity of liquid in the lower liquid cavity, and the turbulent flow is reduced.
Preferably, the first partition and the second partition are made of magnet materials, and when the rotating spring is relaxed, the first partition and the second partition are magnetically connected. The magnetic connection can ensure that the first partition plate and the second partition plate can be mutually attracted and connected when being close to each other, and the aim of reducing the turbulent flow of the lower liquid cavity is quickly fulfilled.
Preferably, the liquid flowing in the upper liquid cavity and the lower liquid cavity adopts magnetorheological fluid, and an electromagnet for applying a magnetic field to the magnetorheological fluid is arranged on the outer side of the bottom plate support. As the hydraulic suspension is generally filled with liquid with certain damping, if magnetorheological fluid is adopted to replace conventional liquid, the flow rate of the liquid in the upper liquid cavity and the lower liquid cavity can be changed under the action of an electromagnet capable of providing a variable magnetic field, and different vibration damping effects are provided. With this design, the sensitivity of the hydraulic mount can be further adjusted.
Compared with the prior art, the invention has the beneficial effects that:
because the raised line structure is added to the main spring inner skeleton, the raised lines play a role of turbulence and can increase the liquid flow velocity of the upper liquid chamber, the vibration reduction effect is improved, and more energy transmitted by the engine is absorbed;
an annular buckle interference riveting process is adopted between the bottom plate bracket and the main spring rubber, so that the liquid seal qualification rate of the upper liquid cavity and the lower liquid cavity is improved, and the possibility of liquid leakage is low;
through the synergism of rotating spring and baffle, the liquid flow velocity in the lower liquid chamber can become fast for the liquid flow velocity in upper and lower liquid chamber, response speed can be faster when the damping effect is exerted, in time give the absorption with the energy that engine vibration produced.
