Embodiment Construction

[0028] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0029] A disc magneto-rheological fluid brake device with high magnetic field utilization, such as figure 1 As shown in , it includes a central shaft 1, a moving disk assembly and a static disk assembly. The moving disk assembly includes a left end cover 3, a right end cover 11, a moving disk 8, a magnetic isolation cylinder 9 and end cover bearings 2 on both sides. The left end cover and the right end cover are installed through the rotation support of the end cover bearings on both sides. The left and right end covers are coaxially fixed through the magnetic isolation cylinder, and the moving disk is fixed in the magnetic isolation cylinder. The left and right two sets of static disc assemblies located inside the left and right end covers ...

Abstract

The invention relates to a disk type magnetorheological fluid brake device having a high magnetic field utilization rate. The disk type magnetorheological fluid brake device having the high magnetic field utilization rate comprises a center shaft, a movable disk assembly and static disk assemblies. A left end cover and the right end cover of the movable disk assembly are rotationally supported and installed on the center shaft through end cover bearings on the two sides. The left end cover and the right end cover are coaxially and fixedly installed through a magnetism-insulating cylinder. A movable disk is fixedly installed in the magnetism-insulating cylinder. The left static disk assembly and the right static disk assembly are installed on the center shaft and located inside the left end cover and the right end cover. Each static disk assembly comprises a magnetizer, a magnetism-insulating ring, a magnetism-conducting ring and a connection web plate. The magnetizers are fixedly installed on the center shaft through the connection web plates. Coils are wound around the magnetizers. The radial outer edge of each magnetizer is fixedly provided with the corresponding magnetism-conducting ring. The space between the outer portion of the static disk assembly and the inner portion of the movable disk assembly is filled with magnetorheological fluid. The disk type magnetorheological fluid brake device is high in magnetic field utilization rate, reliable in use, wide in adjustment range, good in expansibility and capable of simplifying the control process of an existing brake system, reducing the weight of the braking system and reducing the use cost at the same time.

Description

technical field [0001] The invention belongs to the field of braking devices for small motor vehicles, small aircrafts and light unmanned aerial vehicles, in particular to a disc-type magneto-rheological fluid braking device with high magnetic field utilization rate. Background technique [0002] Braking devices can be seen everywhere in daily life, and there are many forms. The basic working principle is to convert the mechanical energy of the rotating machinery into other energy and dissipate it to the outside to achieve deceleration. At present, the most important way is to rely on the relationship between moving parts and stationary parts friction between them. The brake device used on the aircraft is mainly the executive device with the hydraulic system as the power source. In order to ensure the effective operation of the brake system, a large number of hydraulic pipelines, hydraulic accessories, and solenoid valves are connected to each other and blended with the elec...
