The Automotive Transmission has so few function:To
change the transmission ratio, to expand the range of variation of the
driving wheel torque and speed, in order to adapt to the frequent
changes in driving conditions, the engine in favorable (higher power and
low fuel consumption) of the conditions of work at the same time;Engine rotation direction is the same case, the car can travel in reverse;Using
neutral, to interrupt the power transmission, and capable of starting
an engine idle speed, and to facilitate the transmission shift or power
output.The
transmission is by the variable speed drive mechanism and the steering
mechanism, the power output when needed, can also be retrofitted. Classified in two ways: to change the way and the different ways to manipulate the sub transmission ratio.Gear ratio:Variable transmission is one of the most widely used. It uses a gear, having a number of setpoint transmission ratio. According
to different types of used gear train axis a fixed transmission
