Abstract:
1. An active electrically controlled non-step speed change mechanism for a vehicle, comprising: a dynamo rotating in forward direction to serve as a motor to provide an power allotment unit with an operation power, and rotating in reversed direction to serve as a generator to charge a storage battery to store electricity therein; an internal combustion engine to provide said power allotment unit with operating power; the power allotment unit receiving the output from said dynamo or said internal combustion engine, and transmitting a combined power to an active electrically controlled non-step speed changer; and the active electrically controlled non-step speed changer receiving the power transmitted from said power allotment unit to control vehicle speed according to different roadway condition and vehicle load and finally transmit the power to wheels; wherein said motor and said internal combustion engine are able to work at the most preferable condition in all low, medium and high speed operation modes, wherein said active electrically non-step speed control is performed by a planetary gear set connection, and wherein said planetary gear set non-step speed change employs two sources of power input, the first one is use of the output power of said power allotment unit as an power input, the second one uses the power produced by forward and reverse rotation of said dynamo (motor-generator) as an input such that the power output from the output shaft of said planetary gear set will be able to maintain said internal combustion engine working at the most preferable region at any different roadway condition and vehicle speed.
