Description
Technical field
It the utility model is related to a kind of dampening apparatus, more particularly to a kind of vehicle dynamic vibration absorber.
Background technology
In the process of moving, different degrees of vibration can occur vehicle for the different parts of car body, car body be taken effectively
Vibration and noise reducing measure, it is significant to the safety and stability of raising car body.
At present, more to reduce structural vibration using dynamic vibration absorber, dynamic vibration absorber is also known as tuned mass damper, its base
Present principles are：By adding a minor structure (i.e. bump leveller), appropriate selection knot in intended vibratory system (i.e. main system)
Structure type, kinetic parameter and the coupled relation with main system of structure, change the vibrational state of main system, so as to expected
The forced vibration response of main system is reduced in frequency range.The design method of dynamic vibration absorber is comparative maturity, but typically conventional
Dynamic vibration absorber only has a resonance point, only plays absorbing in a certain intrinsic frequency, in the situation that Vibration Condition is complicated and changeable
Under, its adaptability is not strong.
In view of it is above-mentioned the defects of, the design people, be actively subject to research and innovation, to found a kind of dynamic vibration absorber, make
It is with more the value in industry.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of dynamic vibration absorber, and it is simple in construction, use
It is convenient, it can continuously adjust the frequency of bump leveller.
The utility model proposes a kind of dynamic vibration absorber, including support, be arranged on the support first vibration pass
Block rubber that sensor, one end are connected with the support, the mass being connected with the other end of the block rubber, set on the support
There is the adaptor being threadedly coupled with it, one end of the block rubber is fixed on the adaptor, and the mass includes some
Individual sub- mass, it is threadedly coupled between the protonatomic mass block, the mass is connected with rope, the rope and the block rubber
Coaxial line is set, and the other end of the rope is connected with disk roller, and the motor for driving the disk roller rotation is fixed with the support.
Further, the adaptor is provided with screw, and the support is provided with the screw coordinated with the screw thread.
Further, the quantity of the block rubber is 2.
Further, the mass is provided with the second vibrating sensor.
Further, the output axis connection that the central shaft of the disk roller passes through belt and the motor.
By such scheme, the utility model at least has advantages below：The utility model can pass through tune mass
Quantity, to adjust the weight of mass, reach regulation bump leveller frequency purpose；Can also be by installing the sons of different densities
Mass, to adjust the weight of mass, reach the purpose of regulation bump leveller frequency；It can also be tightened up by the rotation of disk roller
And payout, block rubber is produced axial stretching, produce deformation, change its rigidity, reach the purpose of regulation bump leveller frequency；
The utility model is simple in construction, easy to use, and the regulative mode of frequency has multiple combinations, and utilization rate is high, versatile.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of specification, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below
Describe in detail bright as after.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to the scope of the utility model.
Referring to Fig. 1, a kind of dynamic vibration absorber described in the preferred embodiment of the utility model one, including support 1, it is arranged on machine
The block rubber 3 of the first vibrating sensor 2, one end and the connection of support 1 on seat 1, the mass being connected with the other end of block rubber 3
4, mass 4 is provided with the second vibrating sensor 5, and the quantity of block rubber 3 is 2.
Support 1 is provided with the adaptor 6 being threadedly coupled with it, and adaptor 6 is provided with screw, and support 1 is provided with and screw
The screw that screw thread coordinates, one end of block rubber 3 is fixed on adaptor 6.Mass 4 includes several protonatomic mass blocks 41, sub- matter
It is threadedly coupled between gauge block 41 also by screw and screw.Mass 4 is connected with rope 7, and rope 7 is set with the coaxial line of block rubber 3
Put, the other end of rope 7 is connected with disk roller 8, and the motor 9 of the rotation of drive roller wheel 8 is fixed with support 1.The central shaft of disk roller 8 leads to
Cross the output axis connection of belt 10 and motor 9.
As needed, under Rotatable unloading or any number of protonatomic mass block 41 of installation, the number of regulator mass 41 is passed through
Amount, to adjust the weight of mass 4, reach the purpose of regulation bump leveller frequency；Can also be by installing the sub- matter of different densities
Gauge block 41, to adjust the weight of mass 4, reach the purpose of regulation bump leveller frequency；It can also be received by the rotation of disk roller 8
Tight and payout 7, block rubber 3 is produced axial stretching, produce deformation, change its rigidity, reach regulation bump leveller frequency
Purpose；Because adaptor 6 is threadedly coupled with support 1, therefore easily block rubber 3 and mass 4 are disassembled, convenient maintenance
And replacing；The utility model is simple in construction, easy to use, and the regulative mode of frequency has multiple combinations, and utilization rate is high, versatility
By force, vibrating sensor is respectively equipped with support 1 and mass 4, is easy to monitor the frequency change of main system and bump leveller, improves and inhale
Shake the practicality of device.
Described above is only preferred embodiment of the present utility model, is not limited to the utility model, it is noted that
For those skilled in the art, on the premise of the utility model technical principle is not departed from, can also do
Go out some improvement and modification, these improvement and modification also should be regarded as the scope of protection of the utility model.
