Abstract
The utility model is a new type of vibration absorber that absorbs vibrating energies. The utility model consists of a bracket, gears, racks, a generator, etc. Linear vibration is converted into rotation through the racks and gears and the generator rotor is driven to rotate and turn vibrating energies into electricity. The generated electricity will be transmitted to other energy-storage or consuming equipment. The utility model is free of oil leakage and has such advantages as durability, simple structure and energy efficiency. The utility model can be used to reduce vibration of automobiles, trains and various types of instruments and equipment.
Description
The utility model relates to a kind of new device that absorbs vibrational energy.
At present, known ride-control mainly is an oil damper, because constantly wearing and tearing between its piston and hydraulic cylinder, so fluid leaks outside easily, and damping hole easily stops up, and is fragile.Also have a kind of magnetic force shock absorber (application number 96204030), the cutting magnetic line movement when magnet that utilization links to each other with the up-down vibration face respectively and coil relative motion is converted into electric energy to vibrational energy.Because the speed (equaling the relative velocity of up-down vibration face) of cutting magnetic line movement is too slow, the absorbing effect of this shock absorber is not obvious, therefore is not applied to vehicle vibration damping.
The purpose of this utility model provides a kind of new type vibration isolator, breaks away from the short-life shortcoming of old-fashioned shock absorber, absorbs vibrational energy efficiently.The vibration damping that can be used for automobile, train, various device, instrument.
The purpose of this utility model is achieved in that by certain driving device, rotate being converted into relative to straight-line oscillation, the rotor that drives electrical generator rotates in stator, utilizes cutting magnetic line movement that kinetic energy is converted into electric energy, again electric energy is exported to energy absorbing device.Described driving device is configured to by a tooth bar, gear, one at least, tooth bar, support connect with relative plane of vibration respectively, gear, electrical generator are rack-mount, tooth bar can slide in the bearing of support, with gear matched, vibration hour rack driven gear rotates, and rotates and passes to generator amature by driving device.
Above-mentioned energy absorbing device can be made up of lead, heating resistor, heat abstractor etc.Electrical generator is converted into electric energy earlier with vibrational energy, and the electric current of output is behind heating resistor, and electric energy is converted into heat energy.Heating resistor can be a resistance unmodified resistance, also can be the resistance of adjustable resistance.Change the damping value that resistance value just is equivalent to change old-fashioned hydraulic damper, this can be according to travel conditions by special control circuit control.Should note adopting certain cooling measure, as heat radiation fuel tank, radiating gill etc.Except vibrational energy being converted into heat energy dissipates, also can be with electric energy input storage battery or other automobile power consumer apparatus of electrical generator output.
For reducing to be subjected to impacting the instantaneous suffered impulsive force of plane of vibration of going up, the damping of shock absorber in compression stroke should be less.This can realize by ratchet device is set in driving device (make the output shaft of tumbler can only folk prescription to rotation), also can the heat sink resistance value difference of compression, extension stroke be realized by adopting diode.In order to prevent contamination by dust, also should dust boot be set at corresponding site.
In order to reduce the volume and weight of electrical generator, can adopt high strength magnet (as Nd-Fe-B series magnet, ferrite etc.) to make the magnetic medium of electrical generator.
In order to reduce noise, the wearing and tearing in gear, the tooth bar motion, can increase wear-resistant material layers such as plastics, nylon at gear, rack surface, or adopt high-abrasive materials such as plastics, nylon to make gear, tooth bar.
Advantage of the present utility model.Straight-line oscillation drives the electrical generator rotation with higher rotation speed after train of gears quickens, so shock attenuation result is better.There is not the leakage of oil problem, prolonged the service life of shock absorber greatly.Simple in structure, requirement on machining accuracy is not high.Also overcome the shortcoming of the easy temperature influence of traditional shock absorber performance in addition.When the power storage that electrical generator is sent is got up or supplied with other vehicle-mounted energy consumption equipment, also play energy-conservation effect.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a forward structure scheme drawing of the present utility model.
Fig. 2 is a schematic top plan view of the present utility model.
Fig. 3 is the circuit diagram of heat abstractor 4 among Fig. 2.
Among Fig. 1: 1, support; 2,3,7, gear; 4, tooth bar; 5,8, antifriction-bearing box; 6, dust boot.
Among Fig. 2: 1, support (being the support 1 among Fig. 1); 2, electrical generator; 3, lead; 4, heat abstractor.
Among Fig. 3: 1,2, utmost point pipe; 3,4, heat sink resistance; 5, electrical generator output electrode.
Be to map conveniently, more than each Tu Zhong general structures such as bearing, radiating gill, dust keeper, lubricating system of having economized picture.Each original paper among Fig. 2 also can be produced in the support 1 in actual manufacturing. Heat sink resistance 3,4 can be placed in the heat radiation fuel tank among Fig. 3, and the heat radiation fuel tank has omitted here.Here so draw just for convenience of description.
In the embodiment shown in fig. 1: gear 3,7 is installed on the same axle.Gear 2,3,7 is installed on the appropriate location of support 1.Support 1 has been a case, and it is enclosed in gear 2,3,7, tooth bar 4 in the shell, also together plays dustproof effect with dust boot 6.Tooth bar 4 by the roller bearing in the support 1 hold 5, restraint of liberty such as roller bearing holds 8, bearing, make it can only slide down.When shaking up and down, tooth bar 4 is slide down in support 1, and band gear 7 and gear 3 one run up, and gear 3 is with gear 2 to change simultaneously.The material of gear light more good more (satisfying under the strong prerequisite) to reduce moment of inertia, can adopt aluminium, plastics etc.Adopting roller bearing to hold 5,8 mainly is the sliding friction that radial thrust causes when reducing gear 7 tooth bars 4.The purpose that adopts a gear is to improve the rotating speed of electrical generator.
Among Fig. 2, the gear 2 in the support 1 links to each other with the axle that drives of electrical generator 2, and the electric current output electrode of electrical generator 2 links to each other with heat abstractor 4 with lead 3.Gear 2 bands
During the driving axle and change of electrical generator, the heat sink resistance of the electric current that sends through heat abstractor 4 in generated heat, and the energy that shakes is converted into heat energy and dissipates.Electrical generator 2 adopts unidirectional DC machine, and when the rotor veer was opposite, the output voltage of electrical generator was also opposite.Therefore, in shock absorber compression stroke and extended travel, the output voltage of electrical generator 2 is opposite.As can be seen from Figure 3, when the voltage direction of electrical generator output electrode 5 is constant, only can flow through among heat sink resistance 3 and the heat sink resistance 4 one of electric current.Voltage direction changes after-current another heat sink resistance of then only can flowing through.Therefore, in shock absorber compression stroke and extended travel, the resistance value of performance thermolysis is different, and this just makes shock absorber compression stroke damping value different with the extended travel damping value.
The resistance value of resistor 3,4 can be adjusted according to travel conditions, and its control system is omitted here and do not drawn.
If wishing the damping value of compression stroke is zero, can on gear 7, escapement be set and realizes.Avoid the friction of brush for alternator contact if desired, can adopt coil to make the electrical generator of stator.Can save the train of gears transmission system, with the output shaft of gear 7 with directly link to each other with motor shaft.
