TRANSMISSION SYSTEM OF QINGQI



TRANSMISSION SYSTEM OF QINGQI



Qingqi is a common public ride being used in some area of Lahore as an economic way of traveling. On one hand it provides relief for people with low income but on other hand its a serious cause of Environmental Pollution !!! Reason for its being environment health hazard is another talk; but today i am going to share about the transmission system of a Qingqi rickshaw.



Qingqi is a three wheeler ride. A motor bike without rear wheel is attached with a rear body having seats for passengers and two wheels. There are three basic ways to transmit engine power to the rear wheel of a motorcycle:
    1. Chain
    2. Belt
    3. or Shaft

Chain final-drive systems are by far the most common. in transmission system of Qingqi, a sprocket mounted to the output shaft (i.e., the shaft in the transmission) is connected to a sprocket attached to the torsion bar of rickshaw by a metal chain. When the transmission turns the smaller front sprocket attached to the torsion bar of rickshaw by a meal chain. When the transmission turns the smaller front sprocket, power is transmitter along the chain to rickshaw, which then turns the rear wheel. this type of system must be lubricated and adjust, and the chain stretches and the sprocket wear, requiring periodic replacement.
