Abstract

Provided is a drive train of a wind turbine. The drive train includes a torque limiter assembly including a torque limiter. The torque limiter includes: a first clamping disk, a friction disk, a second clamping disk, and a preloading means. The clamping disks and the friction disk are configured such that the clamping disks frictionally transmit a torque to the friction disk. The torque limiter assembly further includes a torque shaft and a hub shaft. The torque shaft is connected to a rotor of the wind turbine, and the hub shaft is connected to a generator rotor of a generator. The friction disk is bolted to the hub shaft via interface bolts from a downwind side, such that the torque limiter is detachable from the hub shaft as a whole. Further provided is a wind turbine.
