It is considered that this is due to the following mechanism. That is, as shown in FIG. 5, since the tire 1 is generally (the radius of the Cr portion R 1 )> (the radius of the Sh portion R 2 ), the tire 1 in the actual vehicle running is different due to the difference in circumferential length.
The slippage (deformation) in the contact surface between the road surface and the road surface shows the loci of the Cr part and the Sh part during tire rolling. As shown in Fig. 6, the Cr part slips backward (to the left in the figure) like F 1 . , Sh is F 2
It is expected to slip forward (to the right in the figure) as shown.

The slip caused by the platform drive and the tire drive can be considered as shown in FIG. That is, according to the platform drive, when the ground contact portion of the tire 1 is viewed as a block, as shown in (a) of FIG. direction)
This is because slippage to (ie, slippage F 2 of the Sh portion in FIG. 6) is promoted and Sh wear is emphasized.

Further, according to the tire driving, as shown in FIG.
As shown in FIG. 6, due to the inertia of the tire grounding base 3, the tire block 1a slips backward (to the right in the figure) (that is, C in FIG. 6).
This is because the slip F 1 ) of the r part is promoted and Cr wear is emphasized.

The braking force (specifically, 10 kgf) is applied to the tire shaft 2. When the braking force cannot be applied to the tire shaft 2 by the braking means 25 (when the braking force is 1 kg), (a) in FIG.
As shown in Fig. 4, the frictional energy of the Sh part is not so different from the frictional energy of the Cr part.
As shown in, when the braking force is applied to the tire shaft 2 by the braking means 25, the friction energy in the Sh portion increases.
That is, by applying the braking force, it was possible to more accurately reproduce the difference in the friction form of the actual vehicle.
