A torque variation absorbing device comprises a drive body for connecting to a drive member, a driven body for connecting to a clutch mechanism, a damping mechanism disposed between the drive body and the driven body, a hysteresis mechanism disposed between the drive body and the driven body and including an elastic member, and a bearing disposed between the drive body and the driven body and including an inner race and an outer race, wherein any one of the inner race and the outer race is pressed by an elastic force of the elastic member in the direction of the drive member from the side of the clutch mechanism.

Torque variation absorbing device

A torque variation absorbing device comprises a drive body for connecting to a drive member, a driven body for connecting to a clutch mechanism, a damping mechanism disposed between the drive body and the driven body, and a hysteresis mechanism disposed between the drive body and the driven body, wherein the hysteresis mechanism includes a low friction member which is pressed by a first elastic member, a high friction member which is pressed to one of the drive body and the driven body by a second elastic member and an engaging member so as to engage the high friction member, the engaging member disposed at the other one of the drive body and the driven body.

Torque variation absorbing device having friction members imparting

A torque variation absorbing device includes a first flywheel and a second flywheel which are rotatable relative to each other via a ball bearing. A hysteresis mechanism is disposed between the first flywheel and the second flywheel so that the first flywheel and the second flywheel are biased in directions away from each other. The ball bearing includes an outer race, an inner race, and a plurality of balls disposed in a space defined between the outer race and the inner race. A ball inlet groove is formed in each of the outer race and the inner race so that the each ball inlet groove opens toward the hysteresis mechanism. The hysteresis mechanism pushes the outer race and the outer race pushes the balls so that the pushed balls push the inner race in a direction away from the hysteresis mechanism. The portion of a ball guide groove formed in the inner race pushed by the balls is continuous in a circumferential direction of the torque variation absorbing device so that an abrasion of the balls due to a discontinuous portion of the inner race does not occur.

An apparatus for absorbing torque vibration comprises inertial bodies comprising first and second flywheels, and a damper mechanism, torque limiting mechanism and hysteresis mechanism interposed between the first and second flywheels. The rotation is transmitted between both flywheels via damper mechanism, torque limiting mechanism and hysteresis mechanism. Resilient members are secured to spring seats, which are engaged with both ends of a spring of the damper mechanism, at an inner-half portion of the spring seat closer to the axis of said flywheels than an axial line of the spring. Excess compression of the resilient members is prevented.

Apparatus for absorbing torque variation

The torque variation absorbing device comprises a driving plate, a flywheel, and a spring mechanism, a damping and torque limiting mechanism and a hysteresis mechanism, installed between the driving plate and the flywheel. The damping and torque limiting mechanism is located radially inwardly of the spring mechanism. The damping and torque limiting mechanism includes a driven disk and a cone spring housing the flywheel. The driven disk is set to cross a center of an end face of the spring mechanism.

A torque variation absorbing device includes a flywheel, a spring mechanism, a torque limiting mechanism and a hysteresis mechanism. The flywheel is divided into two parts to form an inertia body. One side of the inertia body is a drive side flywheel and the other is a driven side flywheel. The hysteresis mechanism includes a friction plate, a thrust plate and a cone spring. The thrust plate has a partially bent portion and the bent portion is received in a bolt hole of an inner body of the driven side flywheel.

Hysteresis mechanism for a torque variation absorbing device

A rotary drive transmitting mechanism comprises a drive plate, a driven plate operably connected to a flywheel, and coil damping springs operably interposed between the drive and driven plates. Each end of the coil spring carries a seat which engages the drive plate or driven plate. Each seat has a surface which impacts against the respective plate. The surface includes concave and convex portions which mate with respective convex and concave portions of the drive plate or driven plate. The concave and convex portions include elastic layers for suppressing noise. Elastic layers are also provided on other surfaces of the seats which face each other through the spring.

Rotary drive transmitting mechanism with damping springs

The torque variation absorbing device comprises a first flywheel, a second flywheel, a spring mechanism, a damping and torque limiting mechanism and a hysteresis mechanism. The hysteresis mechanism comprises a friction plate and a cone spring interposed between the first and second flywheels. The friction plate comprises a friction lining and a ring plate fastened to the friction lining. The ring plate has a connecting element to be connected with the first or second flywheel. A space is formed between the friction lining and the connecting element, and therefore, when the friction lining material is fastened, such as by hot-pressing or adhesive, to the ring plate, the space prevents friction lining material from flowing out before hardening and adhesive agent from spreading. In this arrangement of the device, when the friction force of the friction plate has worn the hysteresis mechanism is able to obtain a stable hysteresis.

A torque variation absorbing device for e.g. an automobile engine includes a hysteretic mechanism, a damper mechanism and a torque limiting mechanism which are disposed between two separate, concentric and rotatable inertial bodies. The damper mechanism comprises a plurality of elastic bodies disposed in series between the inertial bodies. A plurality of friction members and a plurality of floating disks are provided between the inertial bodies so that the floating disks may create a very small magnitude of hysteresis through the friction members and act upon at least one of the elastic bodies upon contraction of the latter to absorb any fine variation in torque.

Device for absorbing variation in torque

The apparatus relates to a device for absorbing torque and includes a first flywheel connected to the output shaft of an engine. A second flywheel, concentric with the first flywheel, is supported by a bearing on the first flywheel. A spring mechanism, a hysteretic mechanism and a slip mechanism are provided between the first and second flywheels. A centrifugal clutch is provided between the first and second flywheels for engaging the first flywheel with the second flywheel when the rotating speed of the engine has increased to a predetermined level.
