  • Publication number: 20050280194
    Abstract: The invention is directed to a rubber mount for supporting a profile rod, and more particularly to a rubber mount for supporting a stabilizer of an automobile. It is the object of the invention to provide a mount of the aforedescribed type that can be installed on the profile rod easily, with only a few operating steps, preferably already at the manufacturer's site, and that has an simple and cost-effective construction. The proposed rubber mount includes an elastomer mounting body with an axially continuous slot which enables the mounting body to be pushed radially onto the profile rod for installation thereon. After installation, the mounting body can be secured with a clamping means (bracket), which according to the invention is formed on the mounting body itself. Stated differently, the bracket and mounting body are formed as a single piece, and the bracket is an integral component of the elastomer mounting body.

  • Patent number: 6951341
    Abstract: 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.
