A bistable permanent magnet steering gear and its actuation method based on buckling beam

Abstract

Disclosed are a buckling beam-based dual-steady-state permanent magnet steering engine and an actuation method thereof. The dual-steady-state permanent magnet steering engine consists of two symmetrical permanent magnets, a central rotary shaft, a rotor and a coil wound thereon, a dual-steady-state mechanism, an external magnetic yoke, a base and a bearing; the N and S poles of the permanent magnets are arranged oppositely; one end of the central rotary shaft is connected with the rotor and the dual-steady-state buckling beam while the other end is connected with the bearing, and the bearing is mounted in the base; the electrified coil is stressed in a magnetic field and drives the rotor and the central rotary shaft to rotate, and then by virtue of the dual-steady-state characteristic of the buckling beam, dual-steady-state angle output is realized; and the dual-steady-state permanent magnet steering engine is simple in structure, capable of realizing bidirectional load driving only needing electrifying in deflection angle switching, and has the characteristic of low energy consumption.

Description

technical field [0001] The invention relates to a steering gear, in particular to a buckling beam-based bistable permanent magnet steering gear and an actuating method. Background technique [0002] The permanent magnet mechanism has few moving parts, simple structure, and high reliability, which meets people's requirements for gradually improving the performance of the steering gear: compact structure, small size, and light weight, while the traditional steering gear has complex structures, mass and volume. Large, difficult to control and many other shortcomings. In the existing permanent magnet mechanism technology, an electromagnetic coil is used to drive the armature to make a linear motion, and then the linear motion is converted into a rotary motion. Therefore, a permanent magnet steering gear with a simple structure, small size, and electromagnetic direct drive is required. Contents of the invention [0003] In order to solve the problems existing in the above-ment...
