Embodiment Construction

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] Such as figure 1 A preferred embodiment of the present invention is shown, a magneto-rheological fluid fan clutch, including a power shaft 1, a fixed sleeve 2 and an output disk 3, and a magneto-rheological fluid is filled between the fixed sleeve 2 and the output disk 3. The cavity 4 is filled with a driving disc 5 and a driven disc 6, the power shaft 1 drives the driving disc 5, the driven disc 6 drives the output disc 3, and the fixed sleeve 2 is provided with a positive coil with opposite magnetic polarity 7 and the negative coil 8, between the positive coil 7 and the negative coil 8 is provided with a spacer 21. The cavity 4 includes a transmission chamber 41 and a pressurized chamber 42. The transmission chamber 41 and the pressurized chamber 42 communicate through a channel 43. The driving disc 5 and the driven disc 6 are located in the transmission chambe...

Abstract

The invention discloses a clutch of a magneto rheological fluid (MRF) fan. The clutch disclosed by the invention comprises a power shaft, a fixed sleeve and an output disk, wherein a cavity filled with an MRF is arranged between the fixed sleeve and the output disk and is filled with a driving disk and a driven disk; the power shaft drives the driving disk and the driven disk drives the output disk; the fixed sleeve is internally provided with a positive coil and a negative coil which have different magnetic pole polarities, and a magnetism-isolation disk is arranged between the positive coil and the negative coil. The clutch disclosed by the invention has the advantages that the positive coil and the negative coil are arranged in the fixed sleeve, so that the output magnetic field is more stable, correspondingly the viscosity change of the MRF is also more stable, and the transmission is smoother; and the positive coil and the negative coil are separated by the magnetism-isolation disk, so that closed magnetic lines are formed, magnetic leakage is less, and the magnetic field distribution is more uniform.

Description

technical field [0001] The invention relates to a fan clutch, in particular to a magneto-rheological fluid fan clutch. Background technique [0002] At present, liquid viscous transmission, as an emerging technology, has attracted more and more attention. Liquid viscous transmission Since there is viscous liquid between the active and passive parts, the active and passive parts are non-rigid and flexible transmission, which can realize stepless speed regulation, and the speed regulation process is soft and stable, with short time, high sensitivity and high precision; The speed is stable, and it is easy to realize remote control and automatic control; the prime mover can be started under light load; liquid viscous transmission has also been widely used in machinery, metallurgy, power generation, chemical industry, mining, vehicles, ships and other industries. [0003] The main structure of the existing magneto-rheological fluid clutch is as follows: between the active part a...
