伝動装置、特に自動車のクランクCVTのための切換可能なフリーホイール装置
Document Type and Number:
Japanese Patent JP2012503152
Kind Code:
A
Abstract:
A switchable free-wheel device for a transmission for a crank-driven CVT of a motor vehicle. The device includes at least one free-wheel unit with a drivable outer ring, an inner ring in the form of an output shaft, and clamping bodies disposed between the rings and rotatable about their longitudinal axes. In the axial direction, each of the clamping bodies includes first and second grooves that are axially spaced from each other and offset relative to each other in the peripheral direction of the clamping body. Annular worm springs surrounding the clamping bodies are displaceable in the axial direction of the body by a switching mechanism, such that the springs engage either in the first groove or in the second groove. The clamping body rotates about its longitudinal axis such that the force applied by the worm spring runs on a side of the longitudinal axis.
