摘要： A friction generating mechanism of a damper apparatus includes a bushing in contact with an annular friction surface of a spline hub, and a cone spring arranged in a compressed state between a retaining plate and the bushing. A first load support surface of the bushing and a second load support surface of the retaining plate have step portions recessed so as to respectively receive an outer peripheral edge and an inner peripheral edge of the cone spring, when the taper of the cone spring is reversed. The radial positions of boundaries of the step portions are in a relationship of D1>D2, which inhibits the cone spring from being reversed even when an excessive load in the axial direction is input.

摘要： Disclosed is a control method for an internal combustion engine (3) including a power generation motor (4) driven by a power of the internal combustion engine (3) and a damper (30) provided between the internal combustion engine (3) and the power generation motor (4) in a power transmission path, wherein a maximum value of a torque fluctuation generated in an event of a misfire occurring in a cylinder of the internal combustion engine (3) is larger than a value at which a displacement of a main damper (30a) of the damper (30) is allowed to be suppressed to be smaller than a displacement at which abutting occurs on a first stopper (31a) by a counter torque of the power generation motor (4), and the control method includes limiting a torque (Te) of the internal combustion engine (3) within a range in which a displacement of the main damper (30a) is allowed to be controlled to be smaller than a displacement at which abutting occurs on the first stopper (31a) by a counter torque of the power generation motor (4).

摘要： A damper device is provided with a first rotating body, a second rotating body, a coil spring and a spring seat. The coil spring is interposed in a circumferential direction between the first and second rotating bodies. The resin spring seat includes a metallic core member inside. The resin spring seat has a seat portion and an overhang portion. The metallic core member has an overhang metallic core part that has a low-rigidity portion and a high-rigidity portion. The low-rigidity portion is provided on a side close to the seat portion with a relatively lower rigidity. The high-rigidity portion is provided on a side far from the seat portion with a relatively higher rigidity.

摘要： A engine starting method is carried out to start an engine of a vehicle. The vehicle includes a first hub, a second hub, and a damper. The damper connects the first hub and the second hub in a power transmission path between the engine and a generator capable of power generation and powered travel. The engine starting method determines whether or not the engine needs to be started, begins to crank the engine via the generator when the engine needs to be started, performs a first ignition when torque fluctuation caused by torsion in the first hub and the second hub is in a range of being absorbable by the damper during the cranking, and suppresses engine torque generated by the first ignition below engine torque generated by second and subsequent ignitions.

The resin spring seat has a seat portion and an overhang portion. The metallic core member has includes a metallic core seat part with a metallic core exposed portion.The metallic core seat part is provided along the spring seating surface in the seat portion of the spring seats. The metallic core exposed portion is exposed so as to be capable of abutting the coil springs. The metallic core exposed portion is provided on a portion of the spring seating surface which slides against the coil springs.
