Now widely usedinautomobilepistonengine,thetorqueandspeedrangeofsmall,andcomplex condition requires use of traction and the car can be a large speed varies within a range, in order to solve this problem, in the transmission system in set the transmission to meet the conditions for the use of complex requirements. With the rapiddevelopmentoftechnology,peoplemoreandmorecarstothehighperformance requirements,life,energyconsumption,vibrationandnoisetoalargeextentdepends onthetransmissionperformance. The design I designed the heavy-duty truck transmission, in the design, I first discussed with the same group of students, on the car made a careful analysis of transmission ratio calculated with reference to the relevant models to finalize the transmissionratioofeachblockforTransmissionofthetransmissionarrangementof the program made a detailed analysis of the final selection among 5 +1 gear shaft transmission, shift in the forms of synchronizer shift, and select the lock pin type synchronizer. Combined with the requirements of the general form of control mechanism used form of direct control mechanism.The design of the transmission thatisnecessarytomeetthedynamicnat
