PCT No. PCT/EP90/01908 Sec. 371 Date Nov. 6, 1991 Sec. 102(e) Date Nov. 6, 1991 PCT Filed Oct. 26, 1990 PCT Pub. No. WO91/07574 PCT Pub. Date May 30, 1991.A drive arrangement for a camshaft (3) of an internal combustion engine is fitted with a facility for rotating the camshaft (3) relatively to a coaxial drive wheel (5) having a switching component (6), which interacts via a spur toothing (7) with the drive wheel (5) and via a helical gearing (8) with the camshaft (3) and can be axially shifted by a servo motor (13). The servo motor (13) is disposed at the end of the camshaft averted from the drive wheel (5). This prevents the axial length of the internal combustion engine from being extended beyond the drive wheel (5) by the servo motor.
