Abstract

PURPOSE: A reducing apparatus for vibration of an engine and an automatic transmission is provided to reduce vibration effectively by a spring with tuning vibration. CONSTITUTION: A reducing apparatus for vibration of an engine(1) and an automatic transmission comprises mounts; a sensing device; a TCU(Transmission Control Unit,55) and first and second solenoid valves(56,57). Each mount comprises a hydraulic room; a piston; first and second springs and first and second hydraulic ports. Mounts control vibration of the engine and the automatic transmission by a position of a change lever; the number of engine revolution; vehicle speed and an opening of a throttle valve. The sensing device comprises an RPM(Revolution Per Minute) sensor(51) and a gear level sensor(52); a vehicle speed sensor(53) and a throttle position sensor(54). The TCU calculates the number of tuning vibration with results of the sensing devices by using a set map. First and second solenoid valves open and close hydraulic pressure of first and second hydraulic ports by a signal of the TCU. Therefore, vibration is reduced effectively because the spring of the hydraulic room has tuning vibration by hydraulic pressure.
