Applied Research of Lock Pin Synchronizer in Tractor Transmission

Abstract

According to the low speed and high torque characteristics of tractor, the paper discussed the application feasibility of the lock pin synchronizer in tractor, and analyzed its running principle and working process. The 3D model of synchronizer is established based on Pro/e software. The dynamic simulation of the synchronizer’s working process is made by the multi-body dynamics analysis software ADAMS. The dynamic simulation curves reflected synchronizer properties such as angular velocity, friction torque and the synchronization time. After being compared with the theoretical calculation value, the results show that there are only some smaller errors exist between theoretical value and simulation value, which verified the accuracy of simulation model.
