20080217824 | Device for Suspending a Unit Such that Vibrations are Damped - The invention relates to a device for suspending a unit, especially a hydraulic unit of an electronically traction-controlled brake system of a motor vehicle. The unit is suspended in a receptacle provided on the vehicle such that vibrations are damped. Hydraulic units of vehicle brake systems are usually equipped with an electric motor for driving pumps located in the hydraulic unit. The brake pressure in the wheel brakes can be modulated via the pumps. The pump drive can cause mechanical and hydraulic vibrations in the unit which can result in unwanted operational noise in case said vibrations are transmitted to the vehicle body without being damped. The improved device is manually preloaded due to limited space for using tools. A clamping mechanism is guided in an axially movable manner on an armature which is fixed to the hydraulic unit and which can be moved from a basic position into a clamping position. The clamping mechanism is interlocked with the armature in both positions. | 09-11-2008 |
