A spring assembly includes a first coil spring and a second coil spring. The second coil spring includes a first winding portion and a second winding portion. The first winding portion includes a plurality of windings from a first winding to at least a second winding. The second winding portion is a portion except for the first winding portion. An outer diameter of each of the plurality of windings of the first winding portion is smaller than an outer diameter of each of at least one winding of the second winding portion. Each of the plurality of windings of the first winding portion includes the substantially same outer diameter.

A method for manufacturing a friction plate provided with a core plate includes subjecting a spline portion formed at an outer periphery or an inner periphery of the core plate to a hardening process by laser.

The present invention provides a modular transmission mechanism for a hybrid power system, and a hybrid power system; the modular transmission mechanism integrates a motor, a rotor support assembly, a clutch, a concentric slave cylinder, and an engine output shaft. On the one hand, the modular transmission mechanism enables an input/output bracket of the clutch to be in drive coupling with the engine output shaft, and the rotor support assembly to be in drive coupling with an input shaft of a transmission; on the other hand, the modular transmission mechanism enables the input/output bracket of the clutch to be in drive coupling with the input shaft of the transmission, and the rotor support assembly to be in drive coupling with the engine output shaft. In this way, the modular transmission mechanism according to the present invention can realize a conversion of the hybrid power system between a P1 architecture and a P2 architecture only by simple adjustment on the structure, thereby reducing the research and development cost and burden consumed by separately developing the P1 architecture and the P2 architecture.

A pack includes a set of first friction disks interleaved with a set of second friction disks to form a stack. An annular pressure plate has an engagement side disposed against the stack. The engagement side includes an outer circumferential edge, an inner circumferential edge, a flat face extending radially inward from the outer edge, a step axially recessed into the engagement side relative to the face, and a tapered face extending from the step to the inner circumferential edge. The tapered face is disposed against an end one of the first friction disks, and the flat face is radially outboard of the first friction disks.

A friction engagement device includes an elastic member between a piston and a friction plate in an axial direction. Elastic member includes: second engaged portion to be brought into engagement with engagement portion of tubular member so as to be movable in axial direction; and annular plate portion sandwiched between pressing surface of piston and friction plate from both sides in axial direction. Surface of annular plate portion facing first axial side is provided with projection and recess arranged alternately in circumferential direction. Assuming that a phase where radial groove provided in pressing surface and projection provided on annular plate portion are located at corresponding positions in circumferential direction is a particular phase, engagement portion of tubular member, first engaged portion of piston, and second engaged portion of elastic member are formed such that piston and elastic member are unable to come into engagement with tubular member at particular phase.
