Abstract
The utility model relates to a tubular noise reduction damper which is a ring body formed by connecting two ends of a hollow tube with a tube plug. Noise reduction agent is arranged inside the hollow tube. The tubular noise reduction damper has the advantages of simple structure, convenient installation and fine noise reduction effect.
Description
Technical field
The utility model relates to a kind of tubular type noise reducing damping device.
Background technology
Fast development along with high speed railway and urban track traffic, noise emission becomes one of emphasis of current national environmental protection improvement, the noise that produces during train operation causes severe noise to pollute for railway environment along the line, but also influence the health of staff and passenger on the car, therefore, the cry that requires the solution railroad noise to pollute becomes increasing.
Though it is a lot of to reduce the measure of railroad noise, as setting up sound-proof wall, because the restriction that circuit is long, wall is high in the railway both sides, sound-proof wall does not have effect substantially for the resident of both sides, road skyscraper, and defectives such as have the construction cost height, the cycle is long, and difficulty of construction is big; If set about from the railway roadbed aspect, adopt solid bed, there is the construction cost height equally, defective such as the cycle is long, and difficulty of construction is big.Therefore, these methods can not be used widely.
Because the noise of unsteadiness of wheels radiation is the train main noise source, the noise reducing damping device is installed on wheel is considered to small investment, effective and easy-to-install a kind of scheme, the noise radiation that therefore reduces wheel are main, the direct methods that solves the train noise.
The method of existing railroad train wheel noise reduction has following shortcoming:
1, existing railroad train wheel noise reduction product majority is to adopt polymer damping material, must be aided with metallic material and install, and causes the noise reduction product weight big.
2, because existing wheel noise reduction product weight is big, and be arranged in the place, outer of wheel, cause launch train moment big, the launch train difficulty causes the train brake difficulty simultaneously.
3, existing wheel noise reduction product can not be adjusted damper according to wheel running velocity and oscillation frequency.
4, existing wheel noise reduction small product size is big, the cost height.
5, existing wheel noise reduction product is installed complexity, can only the wheel of part type be suitable for, and Applicable scope is narrower, and a lot of wheels are not adorned.
6, existing wheel noise reduction product is short service life, has increased maintenance and replacement cost.
7, existing wheel noise reduction product safety performance is not high.
The utility model content
At the problems referred to above, the purpose of this utility model is, a kind of tubular type noise reducing damping device is provided, and this damper structure is simple, and is easy for installation, excellent noise reduction effect.
For achieving the above object, the utility model adopts technical scheme as follows:
A kind of tubular type noise reducing damping device, it is to connect the torus that the two ends of a hollow tubular form by pipe plug, is provided with the noise reduction agent in the described hollow tubular.
The cross section of described hollow tubular is circle, the shape of a hoof etc.
Described tubular type noise reducing damping device vertically places in the groove of wheel rim inner ring setting.
The utility model compared with prior art has the following advantages:
1, the utility model is to connect the torus that the hollow tubular at two ends is processed into by pipe plug, and production technology is simple, and is easy to process.
2, be provided with the noise reduction agent in the utility model and carry out damping noise-reducing, promptly when vibrations took place wheel, vibrations were given the noise reduction agent by tube wall with shock transfer, inhaled the ability of making an uproar because the noise reduction agent has very strong energy-absorbing, thereby reached the effect of damping noise-reducing.
3, owing to the dissipation factor difference of noise reduction agent to various oscillation frequencys, the utility model can adopt different noise reduction agent at the vibration of different frequency.
4, the utility model vertically places in the groove of wheel rim inner ring, do not change the staring torque of train, do not influence the startup and the brake of train, and principle according to friction energy-dissipating between the interface, promptly when vibration takes place in wheel, friction produces the interface damping energy dissipation between damper and the wheel, play suppress wheel radially with the effect of lateral vibration radiation, thereby obtain noise reduction preferably.
5, the utility model is fixedly installed in the groove of rim for automobile wheel, have easy for installation, volume is little, in light weight, applied range, oil resistant dirt, advantage such as ageing-resistant, heat-resisting, once installation, the lifelong use.

The specific embodiment
As shown in Figure 1, 2, a kind of tubular type noise reducing damping device described in the utility model, this tubular type noise reducing damping device are the torus that is processed by the two ends that pipe plug 2 connects a hollow tubular 1, are provided with noise reduction agent 3 in the described hollow tubular 1, and the cross section of described hollow tubular 1 is circular.
Shown in Fig. 3,4,5, during use, described tubular type noise reducing damping device is positioned in the groove 5 of wheel rim 4 inner rings setting.
Embodiment 2
Shown in Fig. 6,7, the difference of present embodiment and embodiment 1 is: the cross section 1 of described hollow tubular is the shape of a hoof.
