耗する傾向がある。2. Description of the Related Art Generally, there are two main forms of wear of a tire contact surface when a vehicle is actually running. One is wear called shoulder wear (hereinafter abbreviated as Sh wear) in which the wear of the shoulder part (hereinafter abbreviated as Sh part) is greater than the wear of the crown part (hereinafter abbreviated as Cr part) of the tire. Is wear called crown wear (hereinafter abbreviated as Cr wear) in which the wear of the Cr part is larger than that of the sh part, and the free rolling wheels tend to wear to Sh and the drive wheels to wear to Cr.

できなかった。However, in the actual vehicle running, even if the tires are the same, it is expected that the wear mode will change depending on the usage environment. Therefore, the influence of the driving method of the front and rear wheels, the camber toe-in, etc. Will receive. Therefore, it is necessary to reflect these effects in the bench wear energy measurement tester. However,
The wear energy of each part of the tire ground contact surface measured by a conventional bench wear energy measuring and testing machine tends to be higher in the Sh part than in the Cr part (Sh wear often seen in free rolling wheels).
The wear often seen on the drive wheels (Cr wear) could not be reproduced.

As shown in, the amount of wear was different. (Note that (a) in Fig. 10 shows the 2000cc class and (b) in Fig. 10 shows the 3000cc class.) Therefore, in the conventional bench wear energy measurement tester, the weight difference is taken into consideration. Could not be reproduced. In this case, the tire size is 205 / 65R15.

, And drive the first motor 14 to drive the transmission mechanism 13
The tire ground base 3 is driven (for example, in the direction of arrow A in FIG. 1) by screwing the screw shafts 9 and 9 back and forth via the gear 12 and the like.

However, by rolling the tire 1 so as to contact the first sensor 19 and the second sensor 20 (for example, the ground contact S 1 shown in FIG.
Ground out to S 2) tire wear energy from to measure. This is performed for each measurement point.

× Δ slip amount]. Ground pressure is the first sensor 19
The amount of Δ slip is measured by the second sensor 20.

It can be seen that the wear energy of the part becomes high.

The wear pattern of the free rolling wheels and the drive wheels in the actual vehicle running is reproduced on the bench, in agreement with the tendency of Cr wear occurring in the drive wheels in the actual vehicle running.

予想される。It is considered that this is due to the following mechanism. That is, as shown in FIG. 6, the tire 1 generally has a radius (Cr radius R 1 )> (Sh radius R 2 ). The locus is indicated by the one-dot chain line, and the Sh part is indicated by the dotted line. Considering this in the ground plane, the slip of the Cr part slips backward (to the left in the figure) as shown by F 1 , and S
It is expected that the r part will slip forward (to the right in the figure) like F 2 .

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. 8, the slip of the tire block 1a is due to the inertia of the tire 1 to the front (right in the figure). direction)
This is because the slip to (that is, the slip F 2 of the Sh portion in FIG. 7) is promoted and the Sh wear is emphasized.

As described above, 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. 7).
This is because the slip F 1 ) of the r part is promoted and Cr wear is emphasized.

精度よく再現できた。In the present invention, however, in the case of the base drive, the braking force (for example, 10 kgf) is applied to the tire shaft 2 by the tire braking means 25, and as shown in FIG.
The friction energy of the h portion is increasing. However, when the braking force cannot be applied to the tire shaft 2 by the braking means 25 (when the braking force is 1 kgf), as shown in (a) of FIG. 5, the friction energy of the Sh portion is equal to that of the Cr portion. While there is not much difference, as shown in FIG. 5B, when the braking force is applied to the tire shaft 2 by the braking means 25, the wear energy of 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.

15である。Further, in the case of tire driving, the grounding platform braking means 30 applies a braking force to the grounding platform 3 (that is, a force that restricts the horizontal movement of the grounding platform 3) and the grounding platform 3 is moved. By making the tire 1 hard to move and giving a torque that overcomes it to the tire 1, the driving force of the tire 1 is increased, thereby increasing the friction energy of the Cr portion, and the measured wear energy is as shown in FIG. , So that it matches the form of actual vehicle wear. In FIG. 4, the white bar represents the case where the ground base brake means 30 applies the braking force to the ground base 3, and the black bar corresponds to the 3000cc class, and the black bar represents the case where the ground base 3 does not apply the brake force. , 2000cc
It matches the class. The tire size is 205 / 65R
It is 15.
