Abstract

A connection device for the torque transmitting connection of a connection component (2) to a hollow shaft (1). The connection component (2) comprises a penetrating recess (8) corresponding in shape to the outside cross section of the hollow shaft (1) for receiving one end of the hollow shaft (1), and the hollow shaft comprises a press-fit plug (9) in the area of the connection to the connection component (2) that forms an interference fit with the inner cross section of the hollow shaft (1). Preferably, the connection device is a press-fit plug (9) additionally designed as a bearing seat (10, 11) for at least one bearing (13, 14) assigned to the hollow shaft. The connection device allows durable and reliable transmission of high torques and it is possible to connect further components to the connection between the hollow shaft and the connection component. The connection device allows a reduction in construction space, mass and costs.
