Abstract

PURPOSE: To obtain a highly reliable auxiliary travelling device for human power tractor, by providing two pneumatic cylinders of big diameter for a use of wheel driving and small diameter for a use of tension, and preferentially actuating the cylinder of big diameter on the basis of diameter difference between the both cylinders.
CONSTITUTION: At the time of light load for the tractor when travelling on a level road, with a pneumatic switch mechanism 6 not operated, a drive belt 10 is made decoupling from a pulley 9. However, at the time of load becoming heavier for the tractor likely when climbing a sloping rode, with a big amount of traction force applied to a traction bar 3, and detected, the pneumatic switch mechanism 6 is automatically operated, and a change-over valve 20 is switched operation. And then, with a tension given to the drive belt 10 by the operation of a pneumatic cylinder 12, the belt comes into a state of close attachment to the pulley 9. Subsequently with the drive belt 10 alternately turning the pulley 9 in the direction of an arrow mark B.C, as shown in the drawing, by the preferential operation of a pneumatic cylinder 14 for the cylinder 12 of small diameter, a wheel 2 can be propelled and driven in a direction A' through a one-way clutch 8. This force can be added to the traction force by human power.
