The damper includes a hollow cylindrical member having a groove extending in an axial direction along its inner peripheral surface. A movable member is disposed in the cylindrical member and is movable axially but non-rotationally. A spring is interposed between the movable member and the bottom of the cylindrical member. A rotating member is rotatable within the cylindrical member. A frictionally resisting force generator resists rotation of the rotating member with respect to the cylindrical member and causes the movable member to move away from the rotating member to increase the frictional resisting force.

Friction damper and pedal device for vehicle having the friction damper

The friction damper includes a hollow cylindrical member having an axially movable non-rotational member within the cylindrical member. A spring is disposed between the movable and cylindrical members. A rotating member lies within the cylindrical member in opposition to the movable member. A frictional resisting element resists relative rotation of the rotating member and the cylindrical member and causes the movable member to move axially away from the rotating member against the bias of the spring to increase the spring force of the spring and the frictional resisting force.

A friction damper includes: a hollow cylindrical member with a bottom; a movable member disposed in said hollow cylindrical member in such a manner as to be movable in an axial direction of hollow cylindrical member but immovable about an axis of hollow cylindrical member; a coil spring disposed between movable member and the bottom of hollow cylindrical member, one end of said coil spring abutting against the bottom of hollow cylindrical member and another end thereof abutting against movable member; a rotating member disposed in hollow cylindrical member in such a manner as to oppose movable member and to be relatively rotatable about the axis of hollow cylindrical member; and a frictionally-resisting-force generating mechanism for generating a frictionally resisting force to the relative rotation of rotating member with respect to hollow cylindrical member, and for causing movable member to move away from rotating member in the axial direction against the resiliency of coil spring and to approach the bottom of hollow cylindrical member so as to increase the spring force of coil spring, thereby increasing the frictionally resisting force.

A one-way damper comprising, one forming member for forming an accommodating chamber, other forming member disposed opposite to the one forming member such that the one and other forming members form the accommodating chamber therebetween and the other forming member is rotatable relative to the one forming member, a coil spring wound around the other forming member, and a viscous fluid accommodated in the chamber.

A vibration damper for damping roll vibration of a power unit mounted on a vehicle body. The vibration damper is composed of a disc plate fixedly connected to the power unit in a manner that the axis of the disc plate is generally parallel with a roll axis of the power unit. The disc plate is sealingly disposed in a chamber formed in a generally circular casing which is coaxial with the disc plate. A viscous fluid is filled in a space defined between the disc plate and inner surface of the casing. The casing is formed of a plastic which has a higher linear expansion coefficient than a metal forming the disc plate, thereby allowing the space filled with the viscous fluid to expand along with thermal expansion of the viscous fluid.

Vibration damper for power unit

A damper used to damp roll vibration of an automotive power unit includes housing in which a disc is immersed in a highly viscous liquid, and a linkage which has universal joints formed at each end thereof. The linkage induces relative rotation between the housing and the disc. A resilient vibration attenuating arrangement is included in one or both of the universal joints for insulating the vehicle chassis from vibration which tends to be freely transmitted through the damper per se and cause cabin reverberation noise.

Damper unit for automotive power unit or the like

A damper comprises housing in which a disc is immersed in a highly viscous liquid, and a linkage which has universal joints formed at each end thereof. The linkage arrangement ensures the maximum amount of relative rotation between the housing and the disc.

A thrust ball bearing unit has a pair of ringed cylindrical upper and lower casings, each casing being made of synthetic resin, a pair of upper and lower races, and a buffer interposed between the upper casing and the upper race or between the lower race and the lower casing. Alternatively, two buffers are interposed between the upper casing and the upper race and between the lower race and the lower casing respectively. The upper and lower casings have peripheral sealing portions which are in a labyrinth or contact seal relationship with each other.
