APPARATUS FOR TESTING DRIVING AND BRAKING OF TIRE FOR VALUATION GROUND PROPERTY OF SAID TIRE

摘要

The invention of the tire and the ground contact pressure of the dynamic characteristics of the shape of the measurement and evaluation of my driving test apparatus of tires relates to, and more specifically, to evaluate the characteristics of the tire ground contact pressure can be obtained is of the dynamic properties of the tire, the ground shape, while simplifying the structure of an evaluation device for measuring the friction energy, and an accurate control of the test conditions and results relates to a driving test device. ; in the evaluation device for measuring the ground characteristic of the tire (2) to be allocated by the rotational torque from the earth bed (1) The invention To this end, the spindle shaft (3 ) on one side of the mounted tire (1) for attaching the adapter (4) attached doedoe torque drum (5) that generates a drive torque and braking torque, the torque of the drum (5), the outer diameter of the weight weight weight 6 is is connected to a wire 7 is wound around multiple pulleys 8 via.
