摘要： This assembly comprises a drive shaft, which is rotatable about a drive axis, and a sliding connection module, the drive shaft comprising: - a driving end portion; - a connecting end portion drivingly connected to the connection module; and - a breakable portion which joins the driving and connecting end portions, and is adapted to break beyond a predetermined torque, the connection module comprising a connection casing which receives the connecting end portion so that it slidable along the drive axis and is coupled to the connection module in rotation, and a guide sleeve comprising a guide ring which guides the driving end portion in rotation and in translation. The guide sleeve further comprises at least a rolling bearing which is adapted to guide the driving end portion of the drive shaft in rotation and in translation. The guide ring is expandable between an initial retracted state of small internal diameter and a dilated state of larger internal diameter, the internal diameter of the rolling bearings being greater than the internal diameter of the guide ring in its retracted state and smaller than the internal diameter of the guide ring in its dilated state.
