Abstract

Provided is a torque converter wherein contact protrusions provided integrally to one of a pair of holding plates which constitute portions of a dynamic damper mechanism are inserted through the cutouts of a spring holding member affixed to a clutch piston. The cutouts (70) are formed such that the inner ends (70a) of the cutouts (70) extending in the radial direction of an output shaft (27) are located on the outside, in the radial direction, of the inner ends (49a) of damper springs (49). The contact protrusions (54b) are each formed such that a part of the contact protrusion (54b) overlaps an inertia plate (58) in a view projected on a plane passing through the contact protrusion (54b) and the axis of the output shaft (27). As a result, the axial distance between the clutch piston and the dynamic damper mechanism can be reduced while the damper spring holding function of the spring holding member is maintained.

Abstract

In a manufacturing method of an impeller for a fluid transmitting device, multiple guide grooves aligned in a peripheral direction to allow communication between adjacent ones of multiple positioning holes are provided in a concave inner surface of a core in advance; and in a step of melting a brazing material and causing the molten brazing material to penetrate into gaps between coupling pieces and positioning holes that are fitted to each other and further into gaps between the core and the blades, the molten brazing material is guided to the positioning holes through the multiple guide grooves. Accordingly, the step allows the molten brazing material to be efficiently guided to the gaps between the coupling pieces and positioning holes, thereby improving the yield of the brazing material and preventing an influence of a residual brazing material over the rotational balance of the impeller.

Abstract

In a fluid transmitting device with a lock-up clutch, each second transmitting claw is formed of: a base portion having a long side arranged in a peripheral direction of a turbine impeller and a short side arranged axially of the turbine impeller; and a claw portion protruding from an intermediate portion of one of long-side portions of the base portion and being inserted between adjacent damper springs, and each short-side portion of the base portion is fixed to the turbine impeller through a weld. A long-side portion of the base portion not welded to the turbine impeller includes a cutout, facilitating bend of the long-side portion when transmitting torque through the second transmitting claw, at opposite sides of the claw portion. This improves engine output performance by relaxing stress concentration at spots where the second claws are welded to a turbine impeller without increasing the thicknesses of the claws.

Abstract

Provided is a process for producing a brake disk having an outer peripheral shape with radial projections and recesses formed repeatedly in the peripheral direction, the process having excellent productivity in that a curved face section can be formed uniformly along the entire perimeter of each outer peripheral edge of the disk body and in that no chamfering step is required for deburring. In the process, a disk body (1) having an outer peripheral shape with repeatedly formed projections and recesses is half-blanked from one surface of a sheet material (W) in the thickness direction thereof, and then, the disk body (1) is blanked from the other surface of the sheet material (W) in the thickness direction thereof. Thus, curved face sections (1b, 1d) created by rollover and contiguous to the respective sheared face sections (1a, 1c) on the outer peripheral surface of the disk body (1) are formed on the respective outer peripheral edges of both said one surface and said other surface, in the thickness direction, of the disk body (1) produced according to the aforementioned process. The inner diameter (R11) of the die (11) that is used in the half-blanking step is smaller than the outer diameter (R12) of the punch (12).
