The invention discloses a lead screw driving reciprocating magnetic type stepping operation system and a method. The system comprises a wheel track and a plurality of lead screw driving reciprocatingmagnetic type stepping operation modules which are repeatedly arranged in the extending direction of the wheel track. Wherein the wheel track is provided with two parallel groove-shaped rails, and thegroove-shaped rails are steel rails. In the system, switchable permanent magnet mechanisms and lead screw reciprocating motion mechanisms of two adjacent stepping operation modules are in different states: a switchable permanent magnet mechanism of one stepping operation module is in an open state, and a lead screw of the lead screw reciprocating motion mechanism rotates forwards; and the switchable permanent magnet mechanism of the other stepping operation module is in a closed state, and the lead screw of the lead screw reciprocating motion mechanism rotates reversely, so that the movementof the stepping operation module on the wheel track is realized. The system provided by the invention can stably operate during ascending and descending of a slope, provides higher traction power andbraking capacity for a rail-mounted system, and eliminates the climbing capacity limitation of the existing rail transit.
本发明公开了一种丝杠驱动往复磁吸式步进运行系统及方法,该系统包括:车轮轨道,和沿车轮轨道的延伸方向重复设置的若干丝杠驱动往复磁吸式步进运行模块;其中,所述车轮轨道具有两个平行的槽形轨道,该槽形轨道为钢制轨道。该系统中相邻两个步进运行模块的可开关永磁磁体机构和丝杠往复运动机构处于不同的状态:一个步进运行模块的可开关永磁磁体机构处于开启状态,丝杠往复运动机构的丝杠正转;另一个步进运行模块的可开关永磁磁体机构处于关闭状态,丝杠往复运动机构的丝杠反转,实现步进运行模块在所述车轮轨道上的移动。本发明的系统能够在上下坡时稳定运行,为轨行系统提供较高的牵引动力和制动能力,消除现有轨道交通的爬坡能力限制。
