Abstract:
An angular transmission, comprising:a housing having magnetorheological fluid (MR fluid) in the interior thereof;a first shaft having a hollow head positioned in said interior of said housing;a second shaft having a hollow head positioned in said interior of said housing, said first shaft being at an angle to said second shaft; andat least one (1) electric coil positioned in the interior of at least one of said hollow head of said first shaft and said hollow head of said second shaft, said at least one (1) electric coil being capable of generating a magnetic field such that said magnetorheological fluid (MR fluid), when exposed to said magnetic field, changes its viscosity to provide for increased shear stress resistance in said magnetorheological fluid (MR fluid) and this change in viscosity of said magnetorheological fluid (MR fluid) provides motion transmission between said hollow head of said first shaft and said hollow head of said second shaft in a rate, or ratio, proportional to said magnetic field generated by said at least one (1) electric coil.
