In certain agriculture applications like front loader, puddling the tractor require repeated forward and backward travel and frequent three point turns on field headlands during loading work. A tractor with limited speed range selection will affect the productivity of operation in reverse motion, as the operator will be stuck with limited speed selection. The forward-reverse capability and
... [Show full abstract] increased speed range can be optioned by a forward reverse module in transmission, which can provide on the go to and from motion by speed reversal. This forward reverse capability can be obtained by using a synchronizer system. Following paper highlights the development of synchronizer module, by studying different synchronizer placements in tractor model, so as to introduce forward-reverse shift capability. Also the factors like inertia, cone torque, coefficient of friction which affect synchronizer performance are studied in detail. Development of a synchronizer module will provide a large speed range selection such as same number of speeds in both forward and reverse, and improve work productivity.
