Abstract
A clutch assembly for automotive vehicles as one application of the rotational torque transmission mechanism comprises an inertia member divided to a driving plate connected to an engine crank shaft and a flywheel connected to a clutch cover. Between the driving plate and the flywheel is provided dampers and a torque limiting clutch which will permit the slidable rotation of the driving plate relative to the flywheel. Thus, any vigorous torque variation on the crank shaft particularly at the low speed of the engine may be absorbed or diminished to thereby avoid the objectionable torque transmission to a clutch output member.
Claims5
A rotational torque transmission mechanism interposed between an input member and an output member, comprising inertia members including a first member fixed to said input member and a second member cooperating with said output member, and means interposed between said first and second members for transmitting a rotational torque of said input member to said output member therethrough, said means including dampers and a torque limiting clutch for limiting the rotational torque transmission, said dampers comprising two parallel discs mounted on said first member, two parallel driven plates fixed to said second member, and resilient elements carried on said discs and driven plates to transmit the torque from said discs to said driven plates, and said torque limiting clutch comprising a spring interposed between said two discs for urging said two discs in an axially opposite direction.
