Abstract
The invention discloses a spring and air bag type damper of an electric vehicle. The spring and air bag type damper of the electric vehicle comprises a damper body, a piston, an inner rod, an outer spring, an upper fulcrum, a lower fulcrum and a high-pressure air bag. The outer spring is arranged outside the damper body in a sleeving mode. The piston is arranged in an inner cavity of the damper body, so that an upper piston cavity is formed. The piston is connected with one end of the inner rod. The other end of the inner rod stretches out from the tail of the damper body and is provided with the lower fulcrum. The upper fulcrum is arranged at the top of the damper body. The high-pressure air bag communicates with the upper piston cavity. According to the damper, damping in all directions can be provided, operation is stable, and the vibration absorption and reduction effect is good.
Description
Technical field
The invention belongs to damper technique field, particularly relate to a kind of electric motor car spring-damper.
Background technology
Make various frictions and other inhibitions that free vibration decays, be referred to as damping, be placed in the special component on structural system and the resistance of motion, the device of depletion kinergety can be provided, become antivibrator.
Between front wheel of electric motorcar and front fork, trailing wheel and seat cylinder, this antivibrator would generally be installed, play buffer shock-absorbing effect. The antivibrator kind occurred in the market is a lot, has hydraulic damper, air-pressure damping device, spring-damper, electromagnetic damper, pulse damper, rotary damper etc. The resistance that hydraulic damper produces when the choked flow aperture mainly by hydraulic oil flow reaches absorbing purpose, and air damper is a kind of vibration absorber utilizing air viscosity, spring-damper is then a kind of elastic mechanism converting mechanical energy into self interior-heat. But effectiveness in vibration suppression is need to improve by above-mentioned various antivibrator.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the present invention provides a kind of electric motor car spring air bag formula antivibrator, it is provided that the damping of all directions, working stability, absorbing good damping result.
Technical scheme: for achieving the above object, technical scheme is as follows:
A kind of electric motor car spring air bag formula antivibrator, including damper body, piston, interior bar, cycle spring, upper fulcrum, lower fulcrum and high-pressure gasbag, cycle spring it is arranged with outside damper body, described piston is arranged on the inner chamber of damper body and forms piston upper chamber, described piston is connected with interior bar one end, and the other end of described interior thick stick stretches out from the afterbody of damper body, and is provided with lower fulcrum, the top of described damper body is provided with fulcrum, and described high-pressure gasbag connects with piston upper chamber.
Further, the gas being filled with inside described high-pressure gasbag is nitrogen or carbon dioxide.
Beneficial effect: 1, pressure-air is contained in high-pressure gasbag by the present invention, it is provided that the damping of all directions, relatively other media, the viscosity of air varies with temperature not quite, and service behaviour tends towards stability.
2, the present invention possesses relatively other types antivibrator, and absorbing damping property is better.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
As described in Figure 1, a kind of electric motor car spring air bag formula antivibrator, including damper body 1, piston 2, interior bar 3, cycle spring, upper fulcrum 5, lower fulcrum 6 and high-pressure gasbag 7, cycle spring it is arranged with outside damper body, described piston 2 is arranged on the inner chamber of damper body 1 and forms piston upper chamber, described piston 2 is connected with interior bar 3 one end, the other end of described interior thick stick 3 stretches out from the afterbody of damper body 1, and it is provided with lower fulcrum 6, the top of described damper body 1 is provided with fulcrum 5, described high-pressure gasbag 7 connects with piston upper chamber, the internal gas being filled with of described high-pressure gasbag 7 is nitrogen or carbon dioxide.
When electric motor car lower fulcrum 6 is by extraneous arbitrary excitation, cycle spring is compressed, and interior thick stick 3 is descending, and piston upper chamber space diminishes, and high-pressure gasbag 7 volume increases, and pressure increases. When cycle spring is in stretched condition, piston upper chamber space becomes big, and high-pressure gasbag 7 volume reduces, and pressure is down to normal condition, and antivibrator completes an absorbing vibration damping in proper order.
Pressure-air is contained in high-pressure gasbag 7 by the present invention, it is provided that the damping of all directions, relatively other media, and the viscosity of air varies with temperature not quite, and service behaviour tends towards stability relatively other types antivibrator, and absorbing damping property is better.
The above is only the preferred embodiment of the present invention; it is noted that, for those skilled in the art; under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
