Considering that when the vehicle body has a high reduction ratio, the speed of the vehicle body is low, at this time the vehicle body transmission shaft can obtain a large torsional moment. According to the vehicle body parameters, it can be known that the engine can obtain a large reduction ratio when in the fourth gear. The transmission efficiency of the engine is now selected to be 0.96.
According to the result of the above calculation, a smaller torque value is selected as the small torque of the drive shaft. The reason why a large value is not selected here is to take into account the design principles of lightweight transmission shafts. In addition, for the vehicle body, it is necessary to protect the engine from damage and other safety parts from being damaged during a large impact load, so the transmission shaft needs to choose a smaller value.
