Abstract: Home-made micro automobile is equipped with the transmission including three forward gears and1 reverse gear. A“power-reserved transmission”,which had two forward gears and one direct gear,was added to the differential drive axle. Therefore,the micro automobile can have six forward gears to enlarge output torque of driving wheels and widen the range of speed,thus the vehicle performance and fuel economy could be improved.

Key words: gear ratio, power, acceleration, specific power, full floating drive axle, tons·100 km fuel economy
