Title:
RUNNING TRANSMISSION OF WORK VEHICLE
Document Type and Number:
WIPO Patent Application WO/2015/060287
Kind Code:
A1
Abstract:
While the running transmission of a work vehicle including a crawler vehicle, such as a combine, is provided with a side clutch, there has been the problem that, even though the vehicle can make a gentle turn when running in a dry paddy as the running axle on the inside of the turn is freely rotated, the running axle on the inside of the turn does not easily rotate when running in a wet paddy because of large running resistance between a ground contacting portion of the crawler and the paddy surface, resulting in a decreased radius of turn and making it difficult to achieve a desired gentle turn. Thus, between the left and right running axles (46L, 46R), a variable capacity type auxiliary clutch mechanism (30) is disposed which is capable of transmitting the driving force of one of the running axles (46L, 46R) to the other running axle while decreasing the driving force to an arbitrary transmission torque.
