Roller free-wheel for vehicle, has pinch rollers made of elastic material that are arranged between inner and outer rings to lock rings against each other, such that self-adjusting clamping gap is provided between inner and outer rings

摘要

The roller free-wheel (1) has an outer ring (2) provided with a cylindrical bearing surface (11), and an inner ring (9) provided with circumferentially distributed clamping ramps (5) and a tread (4). A pinch roller cage has several pinch rollers (6) made of elastic material that are arranged between inner ring and outer ring so as to lock the rings against each other, such that self-adjusting clamping gap (y) is provided between inner ring and outer ring. The diameter of the pinch rollers is extensible based on the deformation of inner and outer rings.
