  • Patent number: 5703284
    Abstract: A device for simulating non-uniform wear on a tread strip of a pneumatic vehicle tire has a support structure and a friction body with radially symmetry connected to the support structure so as to be rotatable about a first axis of rotation. The friction body has a rigid circumferential mantle surface with a continuous, permanent friction coating. A receptacle is rotatably connected to the support structure for receiving a vehicle wheel with pneumatic vehicle tire. The vehicle wheel is rotated about a second axis of rotation with the receptacle. A load applying member is connected to the receptacle and extends radially relative to the friction body. It acts radially onto the receptacle for pressing the pneumatic vehicle tire onto the friction coating for generating wear at the pneumatic vehicle tire. A first control device for pivoting the second axis of rotation of the vehicle wheel about a first pivot axis is provided. The first pivot axis extends perpendicular to the first axis of rotation.
