Patent number: 6951341Abstract: The invention relates to a stabilizer for a motor vehicle. Known one-piece stabilizers are designed either solely for operation in road traffic or solely for off-road operation. Two-piece stabilizers that comprise an engaging and disengaging clutch have disadvantages regarding quality and safety. The invention provides a clutch, drivers (14, 17) of which form at least two adjustable gaps in the peripheral direction. The gaps can be filled by at least two locking elements (25) that can be displaced to a certain extent. The locking elements (25) and said drivers (14, 17) are constantly in positive engagement with one another in the peripheral direction and are adjusted to one another in such a manner that the locking elements (25) and the drivers (14, 17) are interlocked without play in the locked final position and that they can be rotated towards one another across a limited angle in the unlocked final position.Type: GrantFiled: May 18, 2000Date of Patent: October 4, 2005Assignee: ZF Lemforder Metallwaren AG.Inventors: Stefan Beetz, Klaus Reichel
