In the drawings: the device comprises a cylinder 1, a top cover 1-1, a connecting rod 2, a spring 3, a guide plate 4, a first metal rubber 5, a second metal rubber 6, a fastening rod 7, a vent valve 8, a first connecting flange 9, a second connecting flange 10, a sealing ring 11, a first electromagnet 12 and a second electromagnet 13.
Detailed Description
Referring to the attached drawings, the invention provides a composite damping device for a new energy automobile, which comprises a cylinder body 1, a connecting rod 2 and a spring 3, wherein one end of the connecting rod 2 is limited in the cylinder body 1, and the spring 3 is sleeved outside the cylinder body 1 and is limited between the cylinder body 1 and the connecting rod 2.
A guide plate 4 is fixed at the bottom of the connecting rod 2, and a first metal rubber 5 and a second metal rubber 6 for clamping the guide plate 4 are arranged in the cylinder 1. The guide plate 4 is used for matching with the inner wall of the barrel body 1 to realize guiding, and is used for limiting the connecting rod 2 by the two metal rubber clamps to realize vibration transmission.
The first metal rubber 5 is located above the second metal rubber 6 and is provided with a through hole through which the connecting rod 2 passes. The aperture of the through hole is larger than the outer diameter of the connecting rod 2. When the shock is absorbed, the first metal rubber 5 is compressed to a certain degree to reduce the aperture of the through hole and slowly press the connecting rod 2 tightly, so that the effect of increasing the shock can be achieved.
A first electromagnet 12 is arranged on the connecting rod 2 positioned in the cylinder body 1, and a second electromagnet 13 is arranged in the cylinder body 1. Specifically, the first electromagnet 12 is fixed on the guide plate 4, and the second electromagnet 13 is fixed on the top inner side or the bottom of the cylinder 1. The magnetic strength and the magnetic pole direction of the two electromagnets can be controlled through a matched controller, and then the electromagnets and the metal rubber are matched to adjust the damping effect.
Two metal rubbers that set up in the barrel 1 can solve the sealed high problem of requirement of current hydraulic damper, have simplified the structure simultaneously, reduce cost and be convenient for maintain. After the installation, when first metal rubber 5 and second metal rubber 6 are in stable state, the external diameter of two metal rubbers is all less than the internal diameter of barrel 1 to the change of metal rubber volume when doing benefit to the shock attenuation of later stage.
After the first metal rubber 5 and the second metal rubber 6 are installed in the cylinder body 1, the first metal rubber and the second metal rubber are in a pressed state under the action of the pressure spring 3, so that the guide plate 3 at the bottom of the connecting rod 2 is stably clamped by the two metal rubbers. Meanwhile, in the initial state, the compression degree of the first metal rubber 5 is larger than that of the second metal rubber 6 due to the acting force of the compression spring 3 on the connecting rod 2. In this state, in order to ensure the damping effect, the length of the second metal rubber 6 is greater than that of the first metal rubber 5, preferably 2 to 3: 1, more preferably 2.5: 1.
a limiting hole matched with the bottom of the connecting rod 2 is arranged in the second metal rubber 6. The diameter of the limiting hole is larger than the outer diameter of the connecting rod 2. First metal rubber 5 is pressed under the effect of spring 3 during initial condition, and second metal rubber 6 also gives connecting rod 2 ascending power through deflector 4 to thereby it is steady when guaranteeing through two metal rubber shock absorptions that deflector 4 is in the state of being centre gripping all the time.
The guide plate 4 is fixed on the connecting rod 2 by means of a fastening rod 7 in threaded connection with the connecting rod 2, and a limiting hole matched with the bottom of the fastening rod 7 is formed in the second metal rubber 6. The guide plate 4 may be fixed directly to the connecting rod 2 or may be fixed by a fastening rod 7. Further, when the second metal rubber 6 is pressed to reduce the aperture of the limiting hole and slowly and tightly press the fastening rod 7 or the bottom of the connecting rod 2, the damping effect can be increased.
Air needs to be compensated into the cylinder 1 or the air in the cylinder 1 needs to be exhausted in the process of shock absorption, and a vent valve 8 is arranged on a top cover 1-1 of the cylinder 1. Further, the vent valve 8 is provided with two check valves which respectively control air to enter the cylinder 1 and control air to be discharged from the cylinder 1.
A sealing ring 11 is arranged between the top cover 1-1 of the cylinder body 1 and the connecting rod 2, so that relative cleanness in the cylinder body 1 is guaranteed, and the effect of vibration reduction caused by dust in the cylinder body 1 is prevented.
The bottom of the cylinder body 1 is provided with a first connecting flange 9, and the top of the connecting rod 2 is provided with a second connecting flange 10. The two connecting flanges are respectively used for limiting two ends of the spring 3. The first connecting flange 9 is in threaded connection with the cylinder body 1 so as to be beneficial to installation and maintenance of metal rubber.
Taking the example that the second electromagnet 13 is fixed on the inner side of the top of the cylinder 1, the working process of the composite damping device is as follows:
micro bumpy road surface: when the road surface is unstable, the tire produces small jolting, just can alleviate the vibration by two metal rubber this moment, and when the tire produced ascending deformation, second metal rubber 6 was compressed, and first metal rubber 5 inflation to the vibration that the absorption tire produced, when the road surface is steady back, second metal rubber 6 resumes, and first metal rubber 5 shrink reaches balanced state simultaneously.
Large bumpy road surface: when large vibration is encountered, in order to buffer vibration at a higher speed, in the process, when the second metal rubber 6 is compressed, the two electromagnets are electrified and kept in a mutually attracted state, the first metal rubber 5 is compressed, and the second metal rubber 6 is released at the same time, so that the second metal rubber 6 is beneficial to further absorbing impact or vibration. When the impact or vibration disappears, the two electromagnets are electrified and kept in a repulsive state, and force opposite to the force just before is formed to assist the metal rubber to return, so that the overall comfort is improved.
The scheme of the invention makes real-time response to road conditions and driving environment by taking the input information of the self-monitoring vehicle body and wheel motion sensors as the basis, provides quick, smooth and continuously variable damping force by using an economic and reliable component structure, reduces vehicle body vibration and increases the adhesive force between tires and various road surfaces. Different from the traditional vibration damping system, the damping system has no small valve structure, and the medium for generating damping achieves the active vibration damping effect without using liquid flow resistance or air compression.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
