SHAFT ASSEMBLY

摘要

The invention relates to a telescopic shaft assembly comprising at least two shaft elements, which can be slid one inside the other and which, in the form of an inner shaft element (5i) and of an outer shaft element (5a), can be connected to one another in a torque-transmitting manner via at least one sliding splining (6). In order to reduce the load exerted upon vehicle occupants in the event of a head-on collision of an all-wheel drive vehicle fitted with a transversally front-mounted engine, the invention provides that an axial fixation (14, 14', 15) in the form of a predetermined breaking point is placed between the shaft elements (5i, 5a) and is rendered inactive when a predetermined impact force acting in the telescoping direction is reached. After the axial fixation (14, 14', 15) has been rendered inactive, the shaft elements (5i, 5a) can, under the action of impact force, move toward one another with a low level of friction along the sliding splining (6).
