Embodiment

[0024] Example: see figure 1 , figure 2 , an electromagnetic extruded magneto-rheological and shape memory alloy friction composite brake, comprising a brake shaft 1, a brake housing and a brake base 2. The brake housing includes a left casing 3 , an outer cylinder 4 and a right casing 5 connected in sequence, and the brake base 2 is fixedly connected to the outer cylinder 4 . The left end of the brake shaft 1 passes through the right housing 5 and then extends into the brake housing, and is rotatably connected with the left housing 3 and the right housing 5 through bearings, wherein the bearings only have oil-sealed bearings, which are sealed The lip is in close contact with the brake disc 6; thereby the automatic casing can be effectively sealed. A brake disc 6 is also provided in the brake housing, and the brake disc 6 is sleeved on the brake shaft 1, and is solidly integrated with the brake shaft 1, and the brake disc 6 is connected with the left housing 3, the outer T...

Abstract

The present invention is an electromagnetic extruded magneto-rheological and shape-memory alloy friction composite brake, which includes a brake shaft, a brake housing and a brake base, and a brake disc is also arranged in the brake housing; the brake disc and the left An armature disc is respectively arranged between the housing and the right housing, and a squeeze disc is arranged between the armature disc and the brake disc, and magnetorheological fluid is filled between the squeeze disc and the brake disc; There are several accommodating grooves, in which a hollow liquid guide rod and a shape memory alloy spring are arranged, and a friction block is arranged at the outer end of the accommodating groove; a liquid guiding rod is arranged between the coil groove and the accommodating groove There are several through holes on the side wall of the hollow liquid guide rod, and the heat conduction liquid is filled in the liquid guide hole, the storage tank and the hollow liquid guide rod. The invention can effectively improve the braking torque of the brake, ensure the braking stability and improve the braking effect.

Description

technical field [0001] The invention relates to the technical field of brakes, in particular to an electromagnetic extrusion magneto-rheological and shape-memory alloy friction composite brake. Background technique [0002] Magnetorheological fluid is a kind of magnetic smart material, which is mainly composed of magnetic particles and base fluid (usually silicone oil), controlled by an external magnetic field, and exhibits the properties of Newtonian fluid when there is no external magnetic field; after adding a magnetic field, the magnetic The viscosity of the rheological fluid changes by several orders of magnitude, showing the properties of Bingham plastic fluid; the whole change process is rapid, reversible, and easy to operate. [0003] Based on the above properties of magnetorheological fluid, it has broad application prospects in the field of clutches and brakes; for example, the "Composite Centrifugal Clutch of Electrothermal Magnetic Shape Memory Alloy and Magnetor...
