Method and device for transmission noise suppression
摘要:
The invention relates to a method and a device for suppressing transmission noise from automatic transmissions, in particular for motor vehicles, the transmission having at least two alternating multi-disk clutches that control a power flow via a gearing mechanism through which oil flows to cool the clutches and to reduce wear and tear on them. To create a method and a device that are of simple design and that can operate without wear and tear, it is proposed that under defined operating conditions of the transmission, the throughput amount of oil is increased in such a way that a defined drag torque occurs at the multi-disk clutch that is opened.
