POWER TRANSMISSION SYSTEM AND ATTENUATION MECHANISM
FIG1 is a block diagram of a power transmission system
As shown in FIG1, a power transmission system 100 is applied to a hybrid car. The power transmission system 100 includes an engine 1, a clutch 2, an electric motor 3, a transmission 4 (exemplary gearbox), a drive wheel 5, a transmission shaft 6 and an attenuation mechanism 7. It should be noted that the power transmission system 100 does not include any clutch between the electric motor 3 and the drive wheel 5.
