The bump leveller majority of the prior art is to reach energy-obsorbing and damping purpose by the self-excited oscillation of resonance block, but structure is simple
Single energy-obsorbing and damping inefficiency, is unable to reach ideal energy-obsorbing and damping effect.Although complicated good damping result, system
Make it is of high cost, installation do not put just, be not easy to promote.
Invention content
In view of the above problems, the technical problem to be solved by the present invention is to:A kind of vehicle frame shock-absorbing means is provided, can effectively be inhaled
Return the vehicle to the garage and knock off the vibration of frame, and with simple in structure, manufacturing cost is low, and shock attenuation result is good, installation and it is easy to maintain the advantages that.
In order to solve the above technical problems, the technical scheme is that：
A kind of vehicle frame shock-absorbing means, including mounting base, rotary disk and the shaft being arranged in the mounting base, the shaft
Sliding bearing is equipped between mounting base；The shaft is fixedly connected between rotary disk by multiple connecting rods；The shaft and return
Absorbing component is additionally provided between turntable；The absorbing component includes energy-absorbing spring, and the middle part of the energy-absorbing spring is equipped with clump weight, and two
End is equipped with fixed block, and external screw thread is machined on the fixed block；Be machined in the shaft and rotary disk with it is described outer
The compatible screw hole of screw thread, the fixed block are mounted in the screw hole；The energy-absorbing spring includes spring body and is sleeved on bullet
The protective jacket of spring outer body.
As an improvement scheme, multiple absorbing components are evenly equipped between the shaft and rotary disk.
As an improvement scheme, in the multiple absorbing component the clump weight of at least one absorbing component and other
The quality of clump weight differs.
As an improvement scheme, between the fixed block and the rotary disk be equipped with cushion.
As an improvement scheme, between the fixed block and the shaft be equipped with the cushion.
As an improvement scheme, the protective jacket be spring protective set.
Above-mentioned technical proposal is used, the beneficial effects of the invention are as follows：
1, when the unexpected forced vibration of vehicle frame, energy is the dynamic of rotary disk and absorbing component by vehicle frame shock-absorbing means sorption enhanced
The potential energy of energy and spring；Then slow release can effectively reduce the vibration and noise of vehicle frame, improve the NVH quality of vehicle.
2, the quality of clump weight differs, and rotary disk can be by eccentric force when rotating so that rotary disk when frame weaving
Rotation is more lasting；Energy-absorbing spring can also store energy and slow release；Therefore the structure can hold the vibrational energy of vehicle frame
The elastic potential energy of the continuous rotational energy and energy-absorbing spring for being converted to rotary disk and absorbing component, then slow release, improves vehicle
The stability of frame, driver and passenger are more comfortable, safe.
3, absorbing component designs for integral type, simple in structure, and dismounting is convenient, and it is convenient to safeguard and replace after damage.

Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, not
For limiting the present invention.
Embodiment
Jointly shown, a kind of vehicle frame shock-absorbing means by Fig. 1 and Fig. 2, including mounting base 1, rotary disk and setting are in mounting base 1
On shaft 2, between shaft 2 and mounting base 1 be equipped with sliding bearing 21.It is fixed by multiple connecting rods 31 between shaft 2 and rotary disk 3
Connection.There are four preferred connecting rod 31 is evenly distributed in the present embodiment.3 are additionally provided with absorbing component 4 between shaft 2 and rotary disk.Absorbing
Component 4 includes energy-absorbing spring 41.The middle part of energy-absorbing spring 41 is equipped with clump weight 42, and both ends are equipped with fixed block 43.Fixed block
On be machined with external screw thread 431.Screw hole 5 compatible with external screw thread 431 is machined in shaft 2 and rotary disk 3, fixed block 43 is pacified
In screw hole 5.Energy-absorbing spring 41 includes spring body 411 and the protective jacket 412 for being sleeved on 411 outside of spring body, protective jacket
412 be spring protective set.Protective jacket 412 can effectively reduce the vibration that spring ring collision generates in telescopic process of energy-absorbing spring 41
