Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention is further described:

[0017] Such as figure 1 As shown, the present invention is an electromagnetic damper that provides initial damping and online adjustable human feeling damping. It is mainly composed of main shaft 1, stator 2, coil winding 3, main friction disc 4, auxiliary friction disc 5, rotor 7, ball bearing 9, gear shaft 10, disc spring 11 and thrust bearing 13, etc. In order to increase the friction arm, the main friction disc 4 and the secondary friction disc 5 are designed at the outermost end of the electromagnetic damper axis. The main friction disc 4 and the main shaft 1 are respectively fixedly connected with the stator 2 through screws. The secondary friction disc 4 and the rotor 2 are fastened with screws. The rotor 7 can rotate on the main shaft 1 via ball bearings 9 . By adjusting the degree of tightening of the nut 12, the deformation amount of the disc spring 11 can be adju...

Abstract

The invention belongs to the field of application and development of aircraft fly-by-wire throttle tables, and relates to an electromagnetic damper capable of providing initial damping and adjusting human-induced damping online. The electromagnetic damper comprises a main shaft (1), a stator (2), a coil winding (3), a main friction disc (4), an auxiliary friction disc (5), a rotor (7), a ball bearing (9), a gear shaft (10), a belleville spring (11) and a thrust bearing (13). The initial damping torque of the electromagnetic damper is adjusted by adjusting the deformation of the belleville spring, so that the initial human-induced damping of the throttle lever in the throttle table is convenient to adjust. According to the electromagnetic damper, the friction pair is designed at the outermost end of the axis of the product, the friction pair with the convex point surface texture is adopted, space and electromagnetic energy are fully utilized, and on the basis that the reliability and the service life of the product are guaranteed, the online adjustable human-induced damping range of the electromagnetic damper is widened. The electromagnetic damper is simple in structure, compact inlayout, small in size and high in reliability and energy efficiency ratio, and is an electromagnetic device with high magnetic density.

Description

technical field [0001] The invention belongs to the application and development field of aircraft fly-by-wire throttle console, and relates to an electromagnetic damper providing initial damping and online adjustable human-inductive damping; an electromagnetic damper with initial damping and online adjustable human-inductive damping (hereinafter referred to as electromagnetic damper), it is used for the pilot to adjust the human-feeling damping of the throttle stick online. Background technique [0002] The throttle console is the interface for the pilot to control the aircraft engine, and the thrust of the engine can be adjusted by pushing the throttle lever on the throttle console. There is a damping device in the transmission link of the throttle lever, which can prevent the throttle lever from loosening and ensure that the throttle lever stays at any position in the stroke. [0003] At present, there are various forms of domestic and foreign damping devices, but the dam...
