In an aspect, an isolator is provided for isolating torsional vibration between a crankshaft of an engine and an endless drive member. The isolator includes a driver drivable by the crankshaft, a pulley that is engageable with an endless drive member, at least one isolation spring that is positioned to transfer forces between the driver and the pulley and to isolate torsional vibrations in the driver and the pulley from one another, and a damping structure configured to frictionally resist relative movement between the driver and the pulley beyond a selected relative threshold angle, and to permit relative movement between the driver and the pulley within the selected relative threshold angle without frictional resistance from the damping structure.

An improved torque converter damper disc and/or clutch (100) that includes the use of a parametric spring system. The parametric spring (500) is configured to address critical inflection and pinch points along the spring longitudinal length (l). These critical points are areas of higher applied stress due to torsional stress and bending stress, the latter of which mainly attributed to centrifugal loading.

In an aspect, a spring assembly is provided for an isolator, and includes first and second helical compression springs, a retainer and a spring housing. The first helical compression spring has a central aperture and has a first end and a second end. The second helical compression spring having a central aperture and having a first end and a second end, wherein the second spring is coaxial with and nested within the first spring. The retainer has a base and a post that extends from the base into the central aperture at the first end of the second helical spring. The spring housing that has an interior space in which the first and second springs are positioned, and further includes a base-engaging aperture that holds the base of the retainer. The spring housing includes a drive wall that is engaged with the first ends of the first and second springs.

In an aspect, an isolator is provided, comprising a hub, a pulley, an isolation spring and a transition spring. The hub defines an axis and is connectable to a rotatable shaft of a rotary device. The pulley is rotatably mounted to the hub. The isolation spring and transition spring act in series in a torque path between the pulley and the hub. The isolation spring has a first spring rate. The transition spring has a second spring rate that is lower than the first spring rate.

摘要:
A torque fluctuation absorbing apparatus is provided which is capable of securely sealing a space housing an elastic member in it even on application of a centrifugal force or at the time of cooling. The torque fluctuation absorbing apparatus includes a center plate, a side plate(s) (side plate assembly) disposed coaxially with the center plate and slidably relative to the center plate, and an elastic member housed within a space delimited by the side plate assembly so as to absorb torque fluctuations produced between the side plate assembly and the center plate. The torque fluctuation absorbing apparatus also includes a cover member secured to the center plate and slidably pressure contacted with the side plate assembly to cover from outside a space housing the elastic member in it, and a suppressing section capable of suppressing the cover member from becoming deformed under a pressure acting on the cover member (25) when an atmospheric pressure within the space housing the elastic member(s) therein has become lower than an outside atmospheric pressure.
