Title:
TORQUE ROD VIBRATION REDUCER
Document Type and Number:
Japanese Patent JP2015121254
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To further enhance torque rod noise/vibration reduction performance for reducing transmission of the torque fluctuation of an engine to a vehicle body.SOLUTION: To a torque rod coupled between an engine and a cabin-side frame of a vehicle body, a cylindrical magnetorheological body surrounding the torque rod is fixedly attached, a coil and a mass member covering the coil being fixedly attached to an outer circumferential surface of the magnetorheological body. The elastic modulus of the magnetorheological body increases by applying a magnetic field generated by a current carried across the coil to the magnetorheological body. A controller supplying the current to the coil controls the current to be carried across the coil on the basis of an input of an engine rotational speed. The magnetic field applied to the magnetorheological body is controlled to regulate the elastic modulus of the magnetorheological body, whereby the mass member is allowed to make a reciprocating motion in a phase cancelling vibration input to the torque rod. It is, therefore, possible to suppress the transmission of the vibration input to the torque rod to a support body.
