Aisin Seiki, Aisin Aw Industries Co. and Exedy Corportion | Date: 2012-11-01

A starting device configured with a multi-plate clutch and a damper device. The damper device may include an input element to which power from a motor is transmitted via the multi-plate clutch, an outer peripheral-side elastic body to which the power is transmitted from the input element, an inner peripheral-side elastic body that is placed on an inner peripheral side of the outer peripheral-side elastic body, an intermediate element that transmits the power from the outer peripheral-side elastic body to the inner peripheral-side elastic body, and an output element to which the power is transmitted from the inner peripheral-side elastic body. The input element may be coupled to a clutch drum of the multi-plate clutch so that the input element and the clutch drum interpose the intermediate element therebetween.

A damper includes an outer cover having a front cover and a rear cover. The covers are joined to form a lubricant oil accommodation chamber for accommodating liquid. A damper device, a limiter mechanism, a first plate including a first collar portion located toward the front of the limiter mechanism, and a second plate including a second collar portion located toward the rear of the limiter mechanism are arranged in the outer cover. The limiter mechanism includes a first limiter plate, which is an input side on the torque transmission path, a second limiter plate, which is an output side on the torque transmission path, and a limiter disc spring, which presses the limiter plates.

A spring retaining space that retains therein an arc spring has a predetermined curvature radius and attachment angle. The arc spring is flexed and retained in the spring retaining space, and thus the curvature radius of the arc spring becomes small, while the attachment angle of the arc spring becomes larger than a free angle. Accordingly, torsion stress with a negative sign is applied to a coil member forming the inner circumferential portion of the arc spring.

A damper device 10 includes a dynamic damper 30 that has third springs SP3 coupled to an intermediate member 12 and that also has, as a mass body coupled to the third springs SP3, a turbine runner 5, a coupling member 31, etc. The third springs SP3 of the dynamic damper 30 are disposed so as to overlap both in the axial and radial directions of the damper device 10 second springs SP2 that are disposed inward of the first springs SP1 to transfer torque between a drive member 11 and a driven member 15. A plane PL including the axes of the third springs SP3 and perpendicular to the axis of the damper device 10 is included in the range of the thickness of spring contact portions 31c of the coupling member 31 in the axial direction of the damper device 10.

A centrifugal-pendulum vibration absorbing device disposed within a liquid chamber that stores a liquid, the centrifugal-pendulum vibration absorbing device having a support member coupled to a rotary element that is rotated by power from a drive device; and a mass body supported by the support member so as to be swingable. An order of vibration of the mass body is determined on the basis of an order of vibration to be damped generated by the drive device in consideration of at least a force caused by a centrifugal liquid pressure generated within the liquid chamber along with rotation of the drive device to act on the mass body.

Respective outer peripheral surfaces (33, 35) of opening-side end portions (30, 31) of a front cover (12) and a pump shell (7), which have been shaped by pressing, are formed by slimming such that the outside diameters of the slimmed outer peripheral surfaces are equal to each other. With the opening-side end portions abutting against each other, a high-energy beam such as a laser beam (R) is radiated toward the abutment surfaces (30, 31) from the radially outer side to weld the abutment surfaces to each other. Consequently, it is possible to perform welding accurately through easy processing in order to easily manufacture a fluid coupling with high precision that facilitates post-processing.

A centrifugal-pendulum vibration absorbing device comprising having a support member coupled to a rotary element that is rotated by power from a drive device, and a mass body coupled to the support member so as to swing about a pendulum fulcrum and rotate about a center of gravity. An order of vibration of the mass body is determined on the basis of an order of vibration to be damped generated by the drive device in consideration of at least a rotational angle of the mass body about the pendulum fulcrum and a rotational angle of the mass body about the center of gravity.
