Abstract: There is provided a drive power transmitting mechanism that can transmit drive power losslessly and can be used in environments where silence is required. The drive power transmitting mechanism includes a rotor having a first outer circumferential surface and rotatable about a first rotational axis, a rotor having a second outer circumferential surface pressed against the first outer circumferential surface and rotatable about a second rotational axis due to a frictional force produced between the second outer circumferential surface and the first outer circumferential surface, a gear rotatable in unison with the rotor about the first rotational axis, and a gear rotatable in unison with the rotor about the second rotational axis, in which the gear and the gear are brought into mesh with each other when the second outer circumferential surface slips against the first outer circumferential surface.

Abstract: A powertrain system for a commercial electric vehicle includes an electric motor, a multi-speed transmission, and a drive line. A reducer assembly is added prior to connection to the drive line to decease the rotational speed generated by the electric motor prior to being transmitted to the drive line. The reducer assembly can be placed before the multi-speed transmission input, after the multi-speed transmission output, or somewhere in between those two locations. The reducer assembly includes a reducer gearset for decreasing shaft rotational speed. The reducer assembly may include adjacent idler gears to reduce the pressure load on the gear teeth of the reducer assembly.
