Disclosed therein are a pulley assembly for a compressor and a manufacturing method of the same, which can prevent possible damages during processing and is fit for high-temperature environment because a pulley is made of magnesium alloy. The pulley assembly includes: a cylindrical hollow pulley made of magnesium alloy; an inner ring formed integrally with the pulley by insert injection molding, the inner ring being fixed to the inner circumferential surface of the pulley and made of a different material from the pulley; and a bearing forcedly pressed and fixed to the inner circumferential surface of the inner ring.

Pulley assembly of compressor and method of manufacturing the same

Disclosed is a field coil assembly of an electromagnetic clutch including a bobbin from which lead wires, which are both ends of a coil made of an aluminum-based material, protrude outward, a core that surrounds the bobbin such that the lead wires are exposed, a bobbin terminal installed at the bobbin while being adjacent to the lead wire of the coil, and a connector coupled to the core and including a lead wire terminal. The lead wires of the coil are connected to the bobbin terminal through heating and pressing.

Field coil assembly of electromagnetic clutch for power transmission apparatus and manufacturing method thereof

The present invention relates to a power transmission device for a water pump, including a pulley, a magnetic flux generator, a disk assembly, and a hub assembly, wherein the disk assembly has a disk, a friction ring for providing a frictional contact with the hub assembly, and a resilient ring adapted to pressurize the friction ring toward the hub assembly, so that when the attracting magnetic flux of the magnetic flux generator is not applied, the friction ring makes a frictional contact with the hub assembly through the resilient pressurization of the resilient ring, whereas, when it is applied, the disk moves toward the pulley to allow the frictional contact between the friction ring and the hub assembly to be released.

Power transmission device for a water pump

The present invention relates to a field coil assembly of an electromagnetic clutch for a compressor. The present invention comprises a core, and a coilinstalled to the coreand formed by winding a unit wire. At this time, the unit wirewound on the coilis made of aluminum, and an area ratio R of an inner sectional area M of the coreto a cross-sectional area of the unit wireis 400 to 640. According to the present invention as above, since the unit wireused for the coilis made of aluminum with a small specific weight and low price rather than copper, the weight of the field coil assemblyis decreased to improve fuel efficiency of a vehicle and decrease a production cost of the field coil assembly

Field coil assembly of electromagnetic clutch for compressor

The present invention relates to a connector of an electromagnetic clutch for a compressor and a manufacturing method thereof. The method includes the steps of arranging a leading end of a lead wireorof at least one discharge deviceor remaining magnetic field removing device, which configures a surge absorbing circuit, to a terminalinstalled in a connectorconfiguring a field coil assembly and having a coupling slotformed in one side thereof; plastically deforming at least one slot bridgeto fix the lead wireorto the coupling slot; and making the connectorin a state where the terminalis fixed to an assembly of at least the discharge deviceor remaining magnetic field removing deviceby injection molding.
