<p>A torque transmission coupling provided according to the present invention comprises a first rotary shaft which is rotated by a driver and rotatively connected to a first rotary load means; a second rotary shaft rotatively connected to a second rotary load means; a hydraulic pump means which includes a first rotor having a prescribed form and disposed on the first rotary shaft so as to be rotated together therewith, and a second rotor disposed on the second rotary shaft so as to be rotated together therewith, and acts so that when a revolution speed difference has occurred between the first and second rotary shafts, the first and second rotors being relatively slided on a each sliding surface thereon by relative rotation corresponding to the difference, to heighten the pressure of liquid-tightly interposed oil and then supply the pressure-heightened oil; a multiple-disk clutch means which includes a group of engaging members disposed on the first rotary shaft so as to be rotated together therewith and be movable in the axial direction thereof relative to the first rotary shaft, and another group of engaging members which are disposed on the second rotary shaft so as to be rotated together therewith and are placed between the former engaging members so as to constitute a multiple-disk clutch, thus making is possible to engage both the groups of engaging members with each other to transmit torque; and a pushing means which includes a hydraulic operating chamber, to which the pressure of the oil from the hydraulic pump means is applied through an oil pressure passage means, and a pushing member, which defines the inner surface of the hydraulic operating chamber and is moved depending on said oil pressure so as to move at least one of the groups of engaging members in such a direction as to reduce the distance between the groups of engaging members to engage the members with each other. When said revolution speed difference has occured between the first and second rotors of the hydraulic pump means, said oil pressure is produced by said relative rotation corresponding to said difference and is then applied to the hydraulic operating chamber through the oil pressure passage means to move the pushing member to engage both the groups of engaging members of the multiple-disk clutch means with each other to transmit said torque from the first rotary shaft to the second rotary shaft. </p> |
