Desigh of the Vehicle Equipped with a Winch and its Travelling Performance on Slope (I)

Design of the Vehicle and Fundamental Performances

Abstract

A vehicle equipped with a winch, in which the winding speed of a wire rope was synchronized automatically with the peripheral speed of driving wheels, was developed and its fundamental performances were investigated.
Results obtained were as follows
1) When the vehicle was used jointly with a winch, the winch and wheels were operated normally. It was possible to move smoothly uphill and downhill.
2) The tractive force of the vehicle used jointly with a winch was larger than the wheel drive only, and increased with increasing the revolution-speed ratio between the winch and wheels.
3) When the vehicle was used jointly with a winch, the variation of travelling speed was little in the range of lower slippage. The higher the revolution-speed ratio, the more outstanding was this tendency.
4) The climbing ability of the vehicle used jointly with a winch was fairly higher than the wheel drive only. It is necessary in the determination of revolution-speed ratio to consider the wheel slippage and the load of winch.
