Abstract

DC60 (13/01/47) to reduce the size/weight and power consumption of the fan connector and to It provides an externally regulated fan connector that is intended to adjust Improved fan control ability. Fan connector which the inside of the sealed housing which has been bearing Resistors on a rotary shaft mounted on a drive plate are separated by a barrier. out into the oil sump and torque transmission chamber that covers the drive plate so that the driving torque can be Get the transmission to the driven side with the oil being fed into the transmission chamber. Torque power is there and so that the oil contact passage may be opened/closed and controlled by the valve assembly to obtain electromagnetic actuation within the device. Connect this fan. Magnetic components of an integrated structure or a modular structure which It consists of a number of parts and is assembled in the same way, arranged. between the electromagnet and the valve assembly (or armature) and the magnetic assembly is assembled inside a sealed housing where the magnetic flux of the electromagnet may has been passed through the magnetic assembly to the armature.

Claims (16)

1. Externally controlled fan coupling device consisting of a housing with a box made of a non-magnetic material and a cover mounted on the box. The housing is supported via bearings on a rotary shaft. A baffle within the housing separates it into an oil sump and a torque transmission chamber. A hole for adjusting the oil feed is formed through the baffle to provide contact between the oil sump and the torque transmission chamber. An oil recovery recirculation passage extends from a position along the outer circumference of the torque transmission chamber to the oil sump. A baffle in the torque transmission chamber is mounted near the oil recovery recirculation passage. A drive disc is fixed to the end of the rotary shaft and is positioned in the torque transmission chamber. A magnetic valve assembly is positioned to selectively open and close the oil feed adjustment hole in the baffle. An electromagnet, supported on the rotary shaft via bearings and critically opposite the oil sump, drives the valve assembly for selective opening and closing and controls the oil feed adjustment hole for flow control. The oil enters the torque transmission chamber to control the torque transmission from the drive disc to the housing and the magnetic assembly. The magnetic assembly is fitted to the housing between the electromagnet and the valve assembly to transmit the magnetic flux of the electromagnet to the valve assembly. This magnetic assembly is an integrated structure with several arrow-shaped holes in the plate assembly, which are sealed by filling these arrow-shaped holes with sealing material. 2. Externally controlled fan connection devices compliant with claim 1, where the sealing material is a rubber sealing material. 3. Externally controlled fan connection device conforming to Requisition 1, in which the steel assembly includes the inner and outer rings and the ring-shaped gap between the rings, and the sealing material that fills the ring-shaped gap and protrudes from the inner and outer rings in at least one place. 4. Externally controlled fan coupling device compliant with claim 1, where the said valve assembly is made with a steel plate spring and armature. 5. Externally controlled fan coupling device conforming to claim 1, where the armature of such valve assembly is positioned between the rotary shaft and the bore for oil feed adjustment. 6. Externally controlled fan coupling device, consisting of a housing with a box made of a non-magnetic material and a cover mounted on the box. The housing is supported via bearings on a rotary shaft. A baffle is housed within the housing and separates it into an oil sump and a torque transmission chamber. A hole for adjusting the oil feed is formed through the baffle to provide contact between the oil sump and the torque transmission chamber. An oil recovery recirculation passage extends from a position along the outer circumference of the torque transmission chamber to the oil sump. A baffle is located in the torque transmission chamber near the oil recovery recirculation passage. A drive disc is fixed to the end of the rotary shaft and is positioned in the torque transmission chamber. A magnetic valve assembly is positioned to selectively open and close the oil feed adjustment hole in the baffle. An electromagnet is supported on the rotary shaft via bearings and is critically opposite the oil sump; this electromagnet drives the valve assembly for selective opening and closing and controls the oil feed adjustment hole for flow control. The oil enters the torque transmission chamber to control the torque transmission from the drive disc to the housing, and the magnetic assembly is fitted into the housing between the electromagnet and the valve assembly to transmit the magnetic flux of the electromagnet to the valve assembly. This magnetic assembly is a modular structure formed into a ring shape, arranged in such a way that the rotary shaft is critically centered on the ring shape. The ring-shaped magnetic assembly includes inner and outer rings arranged to define the ring-shaped gap between the rings. 7. Externally controlled fan coupling device compliant with claim 6, where the inner and outer rings are connected by a non-magnetic material that is fitted and fixed between the inner and outer rings. 8. Externally controlled fan coupling devices conforming to claim 6, where the inner and outer rings are fitted and secured by rings made of non-magnetic material, and where such non-magnetic ring and the outer ring are connected by brass brazing. 9. Externally controlled fan coupling devices conforming to claim 6, where the inner and outer rings are fitted and secured by rings made of a non-magnetic material, and where the ring-shaped gap is sealed by filling it with a sealing material. 10. Externally controlled fan connection devices compliant with claim number 9, where the sealing material is a rubber sealing material. 11. Externally controlled fan connection devices conforming to claim 9, where such sealing material fills at least one of the ring-shaped gaps protruding from the inner and outer rings. 12. Externally controlled fan coupling devices conforming to claim number 6, where the said inner ring and the said outer ring are connected by a non-magnetic material placed in a certain section within the said ring cavity, and where the ring cavity in other sections besides the parts connected by the non-magnetic material is sealed by filling the sections with a sealing material. 13. Externally controlled fan connection devices compliant with claim number 12, where the sealing material is a rubber sealing material. 14. An externally controlled fan connection device conforming to claim number 12, where such sealing material fills at least one of the ring-shaped gaps protruding from the inner and outer rings. 15. Externally controlled fan connection device conforming to claim 13, where the aforementioned ring-shaped rubber sealing material is dried and molded onto the said inner and outer rings. 16. Externally controlled fan connection device conforming to claim 15, where such sealing material fills at least one of the ring-shaped gaps protruding from the inner and outer rings to the valve assembly.
