Summary of the invention
The purpose of this utility model is to provide a kind of series connection vibration damper, to solve the poor problem of effectiveness in vibration suppression of existing torque absorber.The utility model also provides the vehicle that uses above-mentioned series connection vibration damper.
In order to realize the problems referred to above, series connection vibration damper of the present utility model adopts following technological scheme: series connection vibration damper, comprise damper unit more than two-stage, every grade of damper unit comprises the shock-absorbing spring of driving disc, driven disc and connection driving disc and driven disc, and a driven disc and another the driving disc of adjacent two-stage damper unit are fixed together.
Between adjacent damper unit, by plural bearing pin, be fixedly connected with.
Between adjacent damper unit, be provided with transfer panel.
Transfer panel is provided with for installing the mounting hole of bearing pin.
Bearing pin is rivet.
On the driven disc of described final stage damper unit, be connected with splined hub.
In order to realize the problems referred to above, vehicle of the present utility model adopts following technological scheme: vehicle, comprise series connection vibration damper, described series connection vibration damper comprises damper unit more than two-stage, every grade of damper unit comprises the shock-absorbing spring of driving disc, driven disc and connection driving disc and driven disc, and a driven disc and another the driving disc of adjacent two-stage damper unit are fixed together.
Between adjacent damper unit, by plural bearing pin, be fixedly connected with.
Between adjacent damper unit, be provided with transfer panel.
On the driven disc of described final stage damper unit, be connected with splined hub.
The beneficial effects of the utility model: series connection vibration damper of the present utility model comprises damper unit more than two-stage, only comprise that with of the prior art the vibration damper of one-level damper unit compares, by the vibration damping of damper unit more than two-stage, can greatly eliminate and impact or vibration, thereby this series connection vibration damper has good effectiveness in vibration suppression.
Further, transfer panel can make to have certain gap between adjacent damper unit, can avoid both to coincide together.
Further, bearing pin is plugged in transfer panel, and during use, transfer panel has and avoids bearing pin because of the excessive shortcoming being twisted off of moment of torsion, can improve the intensity of bearing pin.
Accompanying drawing explanation
Fig. 1 is the embodiment's 1 of series connection vibration damper of the present utility model plan view;
Fig. 2 is the half sectional view of Fig. 1.
Embodiment
The embodiment 1 of series connection vibration damper of the present utility model, as shown in Figure 1-2: this series connection vibration damper comprises two-stage damper unit, every grade of damper unit comprises the shock-absorbing spring of driving disc, driven disc and connection driving disc and driven disc.
Two-stage damper unit is respectively first order damper unit 1 and second level damper unit 2, the driving disc of first order damper unit 1, driven disc and shock-absorbing spring are respectively the first driving disc 11, the first driven disc 12 and the first shock-absorbing spring 13, and the driving disc of second level damper unit 2, driven disc and shock-absorbing spring are respectively the second driving disc 21, the second driven disc 22 and the second shock-absorbing spring 23.On the second driven disc 22, be connected with splined hub 24, splined hub 24 is located at the inner side that the footpath of the second driven disc 22 makes progress.The axis of splined hub 24 is parallel with the axis of the second driven disc 22.
Between the first driven disc 12 and the second driving disc 21, by bearing pin 3, be fixedly connected with, the first driven disc 12 and the second driving disc 21 are also provided with transfer panel 4, on transfer panel 4, offer mounting hole, bearing pin 3 is threaded onto in mounting hole, in the present embodiment, bearing pin is rivet, and in other embodiments, bearing pin also can be screw rod.Transfer panel has two effects, and the one, make to keep certain spacing between adjacent shock-absorbing spring, avoid the shock-absorbing spring in adjacent two-stage damper unit to bump; Another is avoid bearing pin to occur bending and deformation and twisted off, and improves the intensity of bearing pin.
The mounting type of shock-absorbing spring: take the first shock-absorbing spring as example, this first shock-absorbing spring is wrapped up by the circular arc type spatial transition of the first driven disc, and the end face of the first shock-absorbing spring is compressed by the cross section of the first driving disc.When work, the first driving disc is delivered to moment and very large impact on the first shock-absorbing spring, drives the first shock-absorbing spring compression, by buffering and the vibration damping of the first shock-absorbing spring, moment and less vibration is delivered on the first driven disc.
Shock-absorbing spring can be selected the spring that rigidity is little or degree of turning angle is large.The first driven disc can be disc-shaped structure, can be also bearing pin shape structure, as long as offer patchhole in centre.
The embodiment's 1 of series connection vibration damper of the present utility model use principle: motor is by the first driving disc 11 of transmission of power to the first damper unit 1, then the first driving disc 11 compresses the first shock-absorbing springs 13, the first shock-absorbing spring 13 after compression transfers a torque on the first driven disc 12, the first driven disc 12 transfers a torque on the second driving disc 21 of the second damper unit 2 by land 4 and bearing pin 3 subsequently, then the second driving disc 21 compresses the second shock-absorbing springs 23, the second shock-absorbing spring 23 is by the splined hub on transmission of power to the second driven disc 22 24, finally by splined hub 24 by transmission of power to follow-up transmission devices such as motors.
The embodiment's 1 of series connection vibration damper of the present utility model beneficial effect: this series connection vibration damper carries out the transmission of moment of torsion and vibration in transmission by two shock-absorbing springs, how compared a shock-absorbing spring with existing vibration damper, the vibration damping that impacts like this or vibrate through two shock-absorbing springs can more be eliminated.
In other embodiments, series connection vibration damper can also comprise three grades of above damper units, and a driven disc and another the driving disc of adjacent two-stage damper unit are fixed together, and on the driven disc of final stage damper unit, are connected with splined hub.
In other embodiments, between driven disc of adjacent damper unit and another driving disc, can also only by plural bearing pin, be connected, can save transfer panel, now bearing pin is rod shaped structure, bearing pin has high rigidity and high strength, only by bearing pin, can make to keep certain spacing between a driven disc of adjacent damper unit and another driving disc, the two ends of bearing pin can be welded on corresponding driving disc and driven disc.
In other embodiments, bearing pin can also not be threaded onto in the mounting hole of transfer panel, and bearing pin and transfer panel interval arrange, and can save the mounting hole on transfer panel.
The embodiment of vehicle of the present utility model, this vehicle comprises series connection vibration damper, and the structure of this series connection vibration damper is identical with the embodiment's of above-mentioned series connection vibration damper of the present utility model structure, and at this, it is no longer repeated.
