Abstract

A damper device includes a damper portion and a limiter portion, and the limiter portion has a first constitutive member formed to cover the damper portion or the limiter portion, a first and second friction materials fixed to a second constitutive member of the damper portion, a cover plate provided so as to be slidable to the first friction material, a support plate arranged so as to be distant from the cover plate at a radially inner portion of the support plate and so as to contact the cover plate at a radially outer portion of the support plate, a pressure plate provided so as to be slidable to the second friction material and a coned disc spring provided between the support plate and the pressure plate, wherein the first constitutive member is at least one of the cover plate and the support plate.

Dependent claims

A damper device comprising:

a damper portion for absorbing a torsion by use of an elastic force;
and
a limiter portion generating a slide when the torsion is not absorbed by the damper portion, and
the limiter portion including:
a first constitutive member formed so as to cover at least one of the damper portion and the limiter portion;
a first friction material fixed to one surface of a second constitutive member of the damper portion;
a second friction material fixed to the other surface of the second constitutive member of the damper portion;
a cover plate provided so as to be slidable to the first friction material;
a support plate arranged so as to be distant from the cover plate at a radially inner portion of the support plate and so as to contact the cover plate at a radially outer portion of the support plate;
a pressure plate provided so as to be slidable to the second friction material;
and
a coned disc spring provided between the support plate and the pressure plate in order to bias the pressure plate toward the second friction material, wherein the first constitutive member is at least one of the cover plate and the support plate.

1 more element

A damper device comprising:

a damper portion for absorbing a torsion by use of an elastic force;
a limiter portion generating a slide when the torsion is not absorbed by the damper portion;
and
one of an intermediate member and an elastic body for covering a clearance formed so as to connect a sliding surface of the limiter portion to the outside of the damper device.
