Seal structure in a torque converter using a magnetorheological fluid

摘要

The pump impeller 11 and the rotary shaft of the turbine runner 15 (the input shaft 3, the main shaft 4) is rotatably supported by the unit housing 6, the power transmission from the pump impeller 11 to the turbine runner 15, filled in the unit housing 6 in the torque converter is performed via the magnetic fluid, which is, the support portion 61 of the input shaft 3 in the unit housing 6, the one-way clutch support 7 as a supporting portion of the main shaft 4, is pressed against the outer circumference of the rotary shaft lip provided with a seal 50, 50, on the inside of the unit housing 6 than the contact point P between the lip seal 50 and the rotary shaft, a first magnet, a second magnet pole opposite from that of the first magnet It is spaced in the radial direction of the rotating shaft and the seal structure in the torque converter using the structure of the magneto-rheological fluid disposed.
