The invention provides a driving device of a traction-free structure elevator, the driving device drives an elevator car to run along a track, the driving device comprises a driving motor, a center frame, a force application piece, at least one group of supporting arms and at least two driving wheels, the supporting arms are mounted on the center frame, the at least one group of supporting arms can rotate relative to the center frame, and the driving wheels are mounted on the center frame. At least one driving wheel is mounted on each group of supporting arms, one end of the force applying piece is connected with the supporting arms, the other end of the force applying piece is connected with the center frame or the supporting arms on the other side of the center frame, and the middle of the force applying piece is used for connecting and bearing moving loads. Acting force is applied to the symmetrically-arranged rotating arm assemblies through the tensioning assembly, so that the driving tires connected with the rotating arm assemblies press the track, the stress of the tensioning assembly is reduced, and the tire tipping moment arm is reduced.
本发明提供了一种无曳引结构电梯的驱动装置,所述驱动装置驱动电梯轿厢沿着轨道运行,所述驱动装置包括驱动电机、中心架、施力件、至少一组支撑臂和至少两个驱动轮,支撑臂安装在中心架上,至少一组支撑臂相对于中心架可以转动,每组支撑臂上安装有至少一个驱动轮,施力件的一端与支撑臂连接、另一端与中心架或中心架另一侧的支撑臂连接,施力件的中部用于连接和承受移动载荷。本发明通过拉紧组件对对称布置的转动臂组件施加作用力,使与转动臂组件连接的驱动轮胎压紧轨道,减小了拉紧组件的受力,减小了轮胎倾翻力矩力臂。
