dcterms.abstractThe invention relates to a non-motor wheel which can be driven by shape memory alloy, wherein the invention comprises: a main frame forming one containing space; a rotation part at one side of main frame to rotate relative to the main frame; ratchet (3); and moving part inside the containing space which comprises pushing rod (13) and two SAM actuators (11, 12); the pushing rod (13) has one main body, and upper and lower arms (13A, 13B) longitudinally extending along front and back directions; the free ends of upper and lower arms are arranged with claw and stop claw matched with ratchet (3); two SAM actuators are independently arranged inside two spaces formed by main frame and the main body of pushing rod (13), to move the pushing rod (13) via alternatively powered. The invention has small volume and simple structure.-
dcterms.abstract一种通过形状记忆合金进行驱动的无马达轮子机构,包括:主体框架,其形成一个容置空间;转动部,设置于主体框架的一侧,可相对于主体框架转动,并包括有棘轮(3);以及移动部,设置于主体框架的容置空间内,包括推拉杆(13)和两个SMA致动器(11,12),其中,推拉杆(13)具有一个主体及沿前后方向纵向延伸的上臂(13A)和下臂(13B),在上臂(13A)和下臂(13B)的自由端分别设置有与棘轮(3)配合传动的棘爪和止回棘爪,两个SMA致动器分别设置在主体框架和推拉杆(13)的主体之间形成的两个空间内,并可通过交替通电往复移动推拉杆(13)。该机构结构简单、体积小,并可产生流畅连续的运动。-
