摘 要：永磁緩速器，由永磁鐵驅動的輔助制動系統，通過永磁鐵將渦電流導入轉子的方式工作，沒有制動蹄或制動盤，非電磁產品，而是永磁鐵產品，不需要外部電源供電。針對目前傳統永磁緩速器普遍存在的一些問題，以及使用過程中出現的漏磁現象等，提出了一種基于液壓原理的永磁緩速器氣隙調節裝置。
關鍵詞：新型永磁緩速器 氣隙調節裝置 結構設計與優化

Abstract：Permanent magnet retarder， an auxiliary braking system driven by a permanent magnet， works by introducing eddy current into the rotor through a permanent magnet. There is no brake shoe or brake disc. It is not an electromagnetic product but a permanent magnet product and does not need external power supply. Aiming at the common problems of the traditional permanent magnet retarder and the magnetic leakage phenomenon in the process of use， a permanent magnet retarder air gap regulating device based on the hydraulic principle was proposed.
Key words：new permanent magnet retarder， air gap adjusting device， structure design and optimization
