Apparatus for measuring a resistance against slippage on road surface |
摘要 |
According to the present invention, an apparatus for measuring a resistance against slippage on the road surface is so constructed that two measuring wheels adapted to be rotated by imparting a tractive force to the apparatus are connected to one another via a torsion bar extending therebetween, a difference in rotation is forcibly produced by changing a rotational speed of one of the measuring wheels and a slippage resistance on the road surface is measured by detecting a torque generated on the torsion bar due to the slippage resistance on the road surface.
