Patent ID: 6837101

Claim:
An apparatus for measuring the properties of rubber elastic tires, in particular motor vehicle tires, in dependence on simulated driving loads and/or running states with means ( 1 ) for rotating a tire ( 8 ) to be measured at a tire contact patch and means ( 5 ) for simulating driving loads and/or running states, in particular with respect to the rotational speed, to the weight load and to the slip angle of the tire ( 8 ), characterized in that a device ( 9 ) for measuring the visco-elastic properties of the tire ( 8 ) is provided at the apparatus and is designed for direct use on the tire ( 8 ) disposed in the apparatus and further characterized in that the device ( 9 ) includes a measuring body ( 12 ) which has a measuring head ( 13 ), which can be placed onto a tire ( 8 ) and which is displaceably mounted relative to a holder ( 11 ) fastened to the apparatus, means ( 16 ) for moving the measuring body ( 12 ) to and fro and means ( 17 , 24 ) for measuring the displacement path of the measuring head ( 13 ) and/or the force acting on the measuring head ( 13 ) during the moving to and fro of the measuring body ( 12 ).
