Description of the Related Art Conventionally, a wheel speed sensor for detecting a wheel speed, switch means for sending a brake signal to a computer, and control of a hydraulic pressure supplied to a brake cylinder or the like based on a control signal from a selected computer have been known. And a control signal for obtaining an appropriate braking force according to a vehicle speed and a road surface condition based on a wheel speed signal from a sensor for each roller on the computer side. While adjusting the mode of the actuator based on the control signal, the wheel speed RS
If the vehicle speed drops significantly to the vehicle speed CS (wheels are approaching the locked state), the hydraulic pressure supplied to the brake cylinder etc. is reduced to reduce the braking force, and the wheel speed RS is reduced to the vehicle speed CS. An ABS system that obtains an optimal braking operation while repeating operations such as increasing a hydraulic pressure supplied to a brake cylinder or the like to increase a braking force when approaching is known. Vehicles incorporating such an ABS system are expected to rapidly spread particularly in the field of large-sized vehicles and luxury vehicles. Therefore, an ABS for determining whether or not the ABS system is operating smoothly is considered. There has been a strong demand for the development of a performance inspection device.

The torque fluctuation is not between the tire, a rotatable sensing roller and hula to accurately detect the rotation of the tire
Placed on the detection roller shaft torque between Lee wheel
It is characterized in that it is performed by the fluctuation detecting means . That is, when the tire is braked by the brake, the rotation speed of the detection roller is reduced in accordance with the braking, but the flywheel tries to continue the predetermined rotation by its inertia force.

作状態を精度よく検査する事が出来る。Therefore, a twisting phenomenon of the shaft occurs between the two members connected via the shaft, and the torque fluctuation value consequently corresponds to the load fluctuation of the tire. Therefore, the ABS operation state can be accurately inspected by taking in the torque value and the rotational speed of the tire via the detection roller.

したトルク値を精度よく得る事が出来る。The detection of the torque value is not directly detected from the pair of rotating rollers supporting the tire whose weight varies, but the weight load is supported by the pair of rotating rollers.
Only the rotation of the ear is once converted into the inertia force of the flywheel, and the fluctuation of the inertia force is detected between the flywheel and the detection roller. That is, since the tire weight fluctuates for each vehicle to be inspected, it is impossible to accurately detect a torque value between the tire and the driving rotary roller. The torque value can be detected simply by obtaining the torque value between the flywheel and the detection roller, which is a constant weight load, so that a torque value proportional to the tire rotation speed can be accurately obtained.

ために、前記効果が一層向上する。Since the tire is supported between the rotating rollers, even if the weight of the tire changes, it has no effect on the detecting roller side. Since the detection roller has a smaller diameter and a smaller weight than the pair of rotating rollers serving as support rollers, the above-described effect is further improved.
