Abstract
A vibration adjustment of a drive assembly is achieved by way of a pivoted mount about a longitudinal vehicle axis of an articulated column. An exhaust system with exhaust mufflers and catalytic converters is used to shift a total powertrain vibration to a lower engine speed, and a significantly improved vibrational behavior can be achieved at idle speed.
Claims20
A device for coupled attachment of an exhaust system to an internal combustion engine or a drive assembly for improving the vibrational behavior at idle speed, the exhaust system having an exhaust pipe system connected with each cylinder side of the motor with a catalytic converter and an upstream exhaust muffler, comprising an articulated column held in a transverse plane of the vehicle coupled with a front side of the internal combustion engine about a horizontally arranged swiveling axis aligned in a longitudinal vehicle direction, the articulated column including, at opposite diverging brackets, mutually spaced holding devices for exhaust pipes of the exhaust system, wherein each of the holding devices is arranged in an exhaust pipe system between the exhaust muffler and the catalytic converter, and wherein the exhaust muffler is connected with the internal combustion engine by way of at least one holding device.
