国产载货汽车的起动机都有一个通病,那就是接通起动机时,小齿轮和飞轮齿环撞齿嚓嚓响(与单向离合器打滑响声不同),而起动不了发动机.次数一多,轻则撞坏飞轮齿环和小齿轮,重则起动机驱动端盖破裂,转子断轴. 相似文献

传动系的弯曲振动及其对汽车飞轮壳强度影响的研究 总被引:2,自引:0,他引:2
本文针对CA141汽车飞轮亮出现早期裂纹这一实际问题,将飞轮壳的强度与汽车传动系的弯曲振动结合起来研究。建立了传动系的弯曲振动模型,计算了系统的固有特性和响应,计算了飞轮壳和离合器壳所受最大弯曲角的响应。建立了飞轮壳及离合器壳的有限元模型,计算了飞轮壳及离合器壳的等效螺旋弹簧刚度,从而将飞轮壳的设计与修改同传动系的弯曲振动及飞轮亮的强度直接联系起来,本文的计算结果与试验取得较好的一致。 相似文献

In the present work, different ventilated disc brake rotor configurations were analysed to enhance the heat transfer rate and obtain the uniform temperature distribution in the rotor. CFD code used in this work was validated at using experimental results obtained by conducting experiments on a test rig. The experimental analysis was performed to calculate the mass flow rate and heat dissipation through the rotor. Further, different types of rotor configurations viz. straight radial vane (SRV), tapered radial vane (TRV), alternate long and short vane (ALSV), variable diameter circular pillars (VDCP) were considered for the analysis. A rotor segment of 20° was considered for the numerical analysis due to its rotational symmetry. CFD results were in good agreement with the experiments. The maximum deviation of the numerical results were about 12 % from the experimental results. It is found from the analysis that among the different types of rotor configurations; variable diameter circular pillars (VDCP) rotor gives better rate of heat dissipation with more uniform temperature distribution in the flow passages. Hence for modern high speed vehicles VDCP rotor may be more appropriate. 相似文献

Range extender modules are one option to compensate for short drive ranges of electric vehicles. The close interaction of combustion engine and generator poses new challenges in development. A key requirement for range extender systems is to be light and virtually imperceptible in operation. High-speed electrical machines aim at increasing power density. However, their introduction in a range extender requires a gearbox. The combustion engine torque fluctuations can lead to rattle in the gearbox. The rattle can be overcome by a dual mass flywheel. An interdisciplinary model is developed and used to analyse three different range extender systems: one with a low speed generator without gearbox, one with a high-speed generator, and one with a high-speed generator and a dual mass flywheel. The efficiency was found to be higher for the system with a low speed generator, whereas the power density and the costs are beneficial for the high-speed concept. A dual mass flywheel eliminates the changes of torque direction in the gearbox. It reduces the speed fluctuations of the gearbox and generator by over 90 % compared to the low speed setup. But it increases rolling moment and subsequently chassis excitation compared to a setup with only a gearbox. 相似文献
