Abstract
Disclosed is a test rig (1) for testing vehicle tires. In one embodiment, the test rig includes a rotating drum (2) on a drum axle (3) and force pick-ups (4, 5, 6) for the determination of a radial force acting on the drum axle (3) and a lateral force acting on the drum axle (3). In one embodiment, the test rig (1) has three uniaxial force pick-ups (4, 5, 6), such that a first and a second force pick-up (4, 5) are arranged so as to determine a radial force, where a third force pick-up (6) is arranged so as to determine a lateral force, and where the first force pick-up (4) and the third force pick-up (6) are coupled. Also disclosed is a method for testing vehicle tires.
Claims19
A test rig for testing vehicle tires, comprising:
- a rotating drum on a drum axle;
- a first force pick-up and a second force pick-up configured and arranged to determine a radial force acting on the drum axle;
- a third force pick-up is arranged to determine a lateral force acting on the drum axle;
- and
- wherein the first, second, and third force pick-ups are uniaxial and wherein the first force pick-up is connected to the third force pick-up by way of a connecting rod.
A test rig for testing vehicle tires, comprising:
- a rotating drum on a drum axle;
- a first force pick-up and a second force pick-up configured and arranged to determine a radial force acting on the drum axle;
- a third force pick-up is arranged to determine a lateral force acting on the drum axle;
- and
- wherein the first, second, and third force pick-ups are uniaxial, wherein the first force pick-up is coupled to a first coupling link, wherein the third force pick-up is in contact with the first coupling link by way of a connecting rod, and wherein the third force pick-up is in contact with the first axial end of the drum axle by way of the connecting rod.
A method for testing vehicle tires, the method comprising:
- providing a test rig comprising a rotating drum on a drum axle and force pick-ups for the determination of a radial force acting on the drum axle and a lateral force acting on the drum axle;
- determining a radial force acting on the drum axle of the rotating drum by means of first and second uniaxial force pick-ups;
- determining a lateral force acting on a drum axle of a rotating drum by means of a third uniaxial force pick-up;
- and
- communicating the lateral force and the radial force between the first uniaxial force pick-up and the third uniaxial force pick-up by way of a connecting rod directly connected to a first coupling link, wherein the first uniaxial force pick-up is directly connected to the first coupling link and the third uniaxial force pick-up is directly connected to the connecting rod.
