Abstract
Synchronizer design optimization is being prime need for smooth gear shifting and shifting noise. Especially in tractors, synchronizers are subjected to different kinds of loads under various field applications such as Puddling, Cultivation, Haulage, Construction equipment, etc. Also, transmission housings act as a part of chassis of the tractor and hence subjected to sever bending loads. Thus, design & evaluation of tractor transmission, meeting the customer requirement is quite complex. Current trends in product development are driven by shortening development time, reduced cost and first-time-right principle. These above requirements drive tractor manufacturers to put more efforts on delivering quality, robust and reliable transmission assembly in time.
Generally the synchronizer packs were validated at sub system level in test rig and further assembled on to the tractor to validate the same in tractor level it requires more time & high cost. Taking the cue of Field to Lab, it is required to validate the synchronizer packs at skid level in lab. This deals with an attempt made to develop test setup with back to back transmission concept in rig to validate the transmission synchronizer. To simulate actual loads to the synchronizer, main clutch was attached to drive shaft to simulate the actual working condition of tractor. Replicating a Field validation to Lab validation test accurately of Synchronizer Validation & there by validating its life prediction.
