Abstract

The invention discloses an intelligent magnetorheological fluid dual-mass flywheel. The intelligent magnetorheological fluid dual-mass flywheel aims to overcome the problem that the damping of a dual mass flywheel is incontrollable in the prior art. The intelligent magnetorheological fluid dual-mass flywheel comprises an outer rotor assembly, magnetorheological fluid (5), an inner rotor (7), an excitation device and a dual-mass flywheel assembly. The external rotor assembly is mounted on the left side of the dual-mass flywheel assembly, a sealing cavity rear cover (9) in the outer rotor assembly is fixedly connected with a first flywheel (18) in the dual-mass flywheel assembly through bolts, the inner rotor (7) is mounted on a second flywheel stepped shaft of a second flywheel (19) in the dual-mass flywheel assembly in a sleeved mode and is connected through a spline pair, the inner rotor (7) is mounted inside the outer rotor assembly, and the clearance among the outer circle surface of the inner rotor (7), the inner circle surface of a sealing cavity front cover (4) in the outer rotor assembly and the inner circle surface of the sealing cavity rear cover (9) in the outer rotor assembly forms a working clearance, namely, a sealing cavity. The sealing cavity is filled with the magnetorheological fluid (5), and the excitation device is fixedly mounted on the periphery of the outer rotor assembly.

Description

technical field [0001] The invention relates to a transmission vibration reduction and damping part of an automobile, more precisely, the invention relates to an intelligent magneto-rheological fluid double-mass flywheel. Background technique [0002] 1. Magneto-rheological fluid effect [0003] The magnetorheological effect means that the magnetorheological fluid can flow freely without the action of a magnetic field, showing the behavior of a Newtonian fluid; after an external magnetic field is applied, it can change from a liquid state to a solid state in an instant (milliseconds). The viscosity suddenly increases by several orders of magnitude so that it loses fluidity, exhibits the behavior of Bingham viscoplastic body, has a certain shear resistance yield stress, and the yield stress of the magnetorheological fluid increases with the increase of the applied magnetic field intensity; and This change of the magnetorheological fluid is continuous and reversible, that is,...
