Disc type magnetorheological dual clutch

Abstract

The invention discloses a disc type magnetorheological dual clutch. The disc type magnetorheological dual clutch comprises a first shell, a second shell, a first outer partition plate, a second outerpartition plate, a first excitation coil partition plate, a second excitation coil partition plate, a first excitation coil, a second excitation coil, a first output disc, a first magnetic input disc,a second output disc, a second magnetic input disc and a plurality of connection rods, wherein the first shell and the second shell are fixedly connected with each other in a circumferential adhesionmanner and are enclosed to form a sealed hollow cylindrical structure; the first outer partition plate and the second outer partition plate are arranged between the first shell and the second shell at intervals and are circumferentially fixedly connected with the first shell and the second shell; the first excitation coil partition plate and the second excitation coil partition plate are ring-shaped and are respectively coaxially arranged in a first cavity and a second cavity and are respectively enclosed to form a first ring cavity and a second ring cavity which are sealed; the first excitation coil and the second excitation coil are respectively coaxially arranged in the first ring cavity and the second ring cavity; the connection rods respectively rotatably pass through the first outerpartition plate and the second outer partition plate; and two axial ends of each connection rod are circumferentially fixedly connected with the first magnetic input disc and the second magnetic input disc respectively.

Description

technical field

[0001] The invention relates to the technical field of automobile transmissions, and more specifically, the invention relates to a disc-type magneto-rheological double clutch. Background technique

[0002] Magneto-rheological fluid is a stable suspension liquid formed by uniformly dispersing micron-sized magnetically polarized particles in a non-magnetic liquid and adding a surfactant. As a typical smart material, the yield stress and viscosity of magnetorheological fluid change with the intensity of the applied magnetic field, and the change is continuous and reversible. Specifically, it is a Newtonian liquid with good fluidity and low viscosity under the action of a zero magnetic field, and a Bingham plasticity that can increase the viscosity by more than two orders of magnitude in milliseconds under the action of a strong magnetic field. body. Utilizing the special mechanical properties of magnetorheological fluid, the clutch can be controlled by an exte...
