Inner mesh gear pump type circulating cooling magnetorheological fluid brake

Abstract

The invention discloses an inner mesh gear pump type circulating cooling magnetorheological fluid brake. The inner mesh gear pump type circulating cooling magnetorheological fluid brake comprises a brake shell, a brake shaft, an excitation coil, a coil mounting ring and magnetorheological fluid; a gear pump assembly is arranged on the outer side of a left end cover, comprises a pump shell, a driving gear, a driven gear ring, a crescent-shaped lever and a cover body, a through hole is formed in the left end cover, and a filter film is arranged in the through hole; an oil outlet hole is formed in the upper part of the cover body; a cooling water tank is further arranged on the upper side of an external round cylinder, and a cooling pipeline is arranged in the cooling water tank; the oil outlet hole in the cover body communicates with one end of the cooling pipeline through a connecting pipeline, and the other end of the cooling pipeline is connected with an inlet of an electromagnetic counterbalance valve; and an oil return hole is formed in the external round cylinder, and an outlet of the electromagnetic counterbalance valve communicates with the oil return hole through a pipeline.According to the inner mesh gear pump type circulating cooling magnetorheological fluid brake, the cooling effect of the magnetorheological fluid can be effectively improved, so that the stability and braking effect of the brake are effectively improved.

Description

technical field [0001] The invention relates to the technical field of brakes, in particular to an internal meshing gear pump type circulating cooling magneto-fluid brake. Background technique [0002] Magneto-rheological fluid is a solid-liquid two-phase functional material whose shape and performance are constrained and controlled by an external magnetic field; it is a magnetic smart material, which is mainly composed of magnetic particles and base fluid, and is controlled by an external magnetic field. When a magnetic field is present, it exhibits the properties of Newtonian fluid; after adding a magnetic field, the viscosity of the magnetorheological fluid will change by several orders of magnitude in a very short time, showing mechanical properties similar to solids; the entire change process is rapid and continuously controllable reversible. [0003] Based on the above-mentioned properties of the magnetorheological fluid, it has broad application prospects in the fiel...
