Described sub-spring is provided with 1～5, and each sub-spring is through slide block and spring compressor series connection.
Described shock absorber is between drive motor and retarder or motor reducer assembly and diff.
Torsion oscillations in the power drive system causes having relative reciprocal change between A end and the secondary part of torsional vibration damper; Can rely on damping fin and friction between the two to consume the energy of torsion oscillations; Play and suppress the torsional resonance response amplitude, and decay is because of impacting the effect of the transient state torsional oscillation that produces.Since the effect of torsional vibration damper, the big lossy of composition of fluctuating in the torque of retarder input, and because the change of transmission system natural frequency, the resonance effect of system obtains obvious suppression.The torsional vibration damper of electronlmobil of the present invention has the effect that reduces bound fraction torsional stiffness, harmony torsional oscillation natural frequency and increase torsional oscillation damping, inhibition torsional resonance response amplitude; Utilize its one of characteristic original battery-driven car power drive system is optimized the problem that low-speed buffeting causes when having improved vehicle launch effectively travelling comfort descends.
Compared with prior art, the present invention has the following advantages:
1. vehicle body low-speed buffeting phenomenon in the time of can significantly reducing to start improves travelling comfort;
2. can tuning power drive system torsional oscillation natural frequency, improve the service life of related elements;
3. repacking on original power drive system, installation cost is low.
4. can adjust the stiffness and damping characteristic of torsional vibration damper according to the system of actual installation flexibly, have wide range of applications.
Description of drawings
Fig. 1 is used for the structural representation of the torsional vibration damper of electronlmobil for the present invention;
Fig. 2 be used for for the present invention electronlmobil torsional vibration damper partly cut open figure;
Fig. 3 is arranged on the scheme drawing on the electronlmobil for torsional oscillation dynamic vibration absorber of the present invention.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in the restriction scope of the present invention.Should be understood that in addition those skilled in the art can do various changes or modification to the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.Below in conjunction with the accompanying drawing illustrated embodiment the present invention is further described.
Shown in Fig. 1～2; A kind of torsional vibration damper that is used for electronlmobil; This shock absorber comprises spring 1, damping fin 2, shock absorber A end 3, shock absorber secondary part 4 and spring fixed seat 5; Described shock absorber A end 3 is through the motor output shaft of spline connection electronlmobil, and described shock absorber secondary part 4 is through the motor input shaft of spline connection electronlmobil, and shock absorber secondary part 4 passes through radial and axial sliding supported condition on shock absorber A end 3; And can relatively rotate with shock absorber A end 3, described damping fin 2 is clipped between shock absorber A end 3 and the shock absorber secondary part 4.Described shock absorber A end 3 is equipped with circumferential rectangle fenestra with shock absorber secondary part 4; Be provided with spring fixed seat 5 in this fenestra; Described spring 1 is placed in the spring fixed seat 5, make shock absorber A end 3 and shock absorber secondary part 4 in a circumferential direction elasticity be connected, and the rectangular window place is provided with the flange that increases with the spring fixed seat area of thrust surface; Prevent that spring 1 from coming off
Described spring 1 is in series by means of slide block and spring compressor by three different sub-springs of load-deflection curve, and the construction parameter of corresponding part is identical with arrangement parameter in each cluster spring.Realize that thus torsional damping arrangement becomes stiffness characteristics.Described sub-spring can be provided with 1～5 as required.
As shown in Figure 3, described shock absorber plays the effect that replaces original coupler between drive motor and retarder, adopts spline to be connected with the front and back element.The path of transmission of power be " drive motor---torsional vibration damper---retarder---diff---semiaxis---wheel ".
