Problems solved by technology

[0018] In this way, when the protruding portion 33 of the toothed concave portion 30 of the drive plate 36' is stretched and cannot move, it cannot be completely connected or released, and there may be gaps between the drive plate 36' and the driven plate 37. Sintering etc. may occur due to useless sliding state

Embodiment Construction

[0095] Next, embodiments of the present invention will be described.

[0096] figure 1 It is a cross-sectional view showing a main part of the friction coupling device according to the embodiment. The frictional coupling device 1 of the embodiment is provided with frictional coupling parts inside and outside the drum, similarly to the conventional example.

[0097] The drum 20 of the press-formed product is respectively equipped with axially outer splines 24 and inner splines 25 on the outer cylinder 22, and the peaks of the outer splines 24 of the outer cylinder 22 become valleys of the inner splines 25 (see figure 2 ).

[0098] A plurality of drive plates 46 are meshed with the inner surface spline 25 as the friction plates on the drive side, and the driven plates 47 as the friction plates on the driven side arranged alternately with the drive plates 46 in the axial direction are formed on the planetary gear mechanism 10 . Splines 14 on the outer periphery of the planet...

Abstract

Provided is a friction coupling device, a friction plate assembling method and a clamp, allowing a friction plate to engage with a drum external spline stamped with a recess on a specified tooth, wherein the projection generated on the recess does not hamper the movement of the friction plate. A driving plate (a friction plate 36) engaged with an external spline (24) forming a recess (30) on teeth (26a) circumferentially arranged at intervals possesses hypodontia parts (40) corresponding with the teeth (26a) and with teeth cut. The hypodontia part further extends outwards to form an inserting part (42). The disc part (21) of a drum corresponds with each hypodontia part (inserting part) to form a reference boss (44). When the notch (82) of a ring plate (81) is embedded with the reference boss through a clamp (80) and is located in the disc part, a guiding sheet (87) combining with the ring plate faces the teeth (26a). The cutting part and the guiding sheet correspond to drive the driving plate to embed into the drum, and the hypodontia parts (inserting parts) face the position of the teeth (26a). The teeth interfering with the projection part of the recess is provided with a notch, and thereby the driving plate moves smoothly.

Description

technical field [0001] The present invention relates to a friction coupling device that is incorporated into a power transmission system such as a vehicle for power transmission and disconnection, and more particularly relates to a friction coupling device that includes a friction coupling portion that presses a friction plate with a hydraulic piston on the outside of a drum of a rotating member and its friction coupling device. Board assembly methods and fixtures. Background technique [0002] As an existing friction coupling device of this kind, the friction coupling part inside and outside the drum is used as a general-purpose rotating part and has a structure in the transmission. Figure 7 structure shown. [0003] The drum 20' is a press-formed product having an inner cylinder 23 and an outer cylinder 22' extending in the same axial direction from a disc portion 21, and the outer cylinder 22' has axial splines on both the inner and outer circumferences. The mountain po...
