如图7所示，是本发明提供的实时恒力拉力器的整体结构示意图，其中：
转轴20可旋转地布置在支架90上；
在转轴20上布置有一个独立恒扭力发生器30、四个辅助恒扭力发生器10(为了看清内部细节，去除了左侧两个辅助恒扭力发生器10)和一个卷线轮40；各辅助恒扭力发生器10的辅助输出轮13与所述转轴20之间布置有离合装置60，使各辅助恒扭力发生器10的辅助输出轮13能够选择动力连接所述转轴20或者断开与所述转轴20的连接；如此提供多组不同大小的拉力。当然，转轴20上的独立恒扭力发生器30以及辅助恒扭力发生器10的数量都不限于上述实施例所展示的那样，实际数目可根据实际需要而自由增减。
如图8所示，所述卷线轮40的内周侧设有所述卡齿35，从而与所述转轴20的卡槽25对应配合，而使卷线轮40能够带动转轴20同步转动。在卷线轮 40的外周侧能够卷绕拉绳(未予图示)，凭借抽动拉绳，能够使卷线轮40旋转，进而带动转轴20同步转动。
如图7、图9、图10、图11所示，所述离合装置60的结构如下：
各辅助恒扭力发生器10的轴向位置固定，并在每个辅助恒扭力发生器10的一侧布置一个能够在所述转轴20上滑移的传动齿盘61，所述传动齿盘61的内周侧设有所述卡齿35(未予图示)而与所述转轴20保持同步转动；
所述传动齿盘61的一端设有单向传动齿，所述单向传动齿与所述辅助恒扭力发生器10的单向啮合齿相对布置而能够啮合；
在传动齿盘61上布置有两个固定部611，可供弹性件(例如拉力弹簧，未予图示)的一端悬挂，弹性件的另一端可固定在转轴20的径向孔22处，使传动齿盘61的单向传动齿在常态下与所述辅助恒扭力发生器10的单向啮合齿相互分离；
在每个传动齿盘61的径向外侧布置有一个插片62，插片62朝向传动齿盘61的一端为具有斜坡的插刃621，另一端设有齿排622并且可滑动地设于卡套63中，卡套63固定，并在卡套63上设有可拨动或可通过旋钮66旋动的齿轮64，所述齿轮64与所述插片62的齿排622啮合，通过手指拨动所述齿轮64旋转，可控制插片62相对传动齿盘61作径向移动，当插片62下移时，通过插刃621的斜坡与传动齿盘61的抵接，可推动传动齿盘61发生轴向移动，使传动齿盘61上的单向传动齿与所述辅助恒扭力发生器10的单向啮合齿形成啮合，而齿盘上移时，推动传动齿盘61在弹性件的作用下发生另一方向的轴向移动，使传动齿盘61上的单向传动齿与所述辅助恒扭力发生器10的单向啮合齿脱离啮合。
如图12所示，是所述离合装置60的另一种可行结构：在传动齿盘61上连接一个拨动机构65(例如拨杆、连杆机构等)，通过外部的拨钮等操作件连动所述拨动机构65，从而控制传动齿盘61在转轴20上的轴向移动，达到离合效果。本实施例中，可设置弹性件，也可不设置弹性件。
如图13所示，是所述离合装置60的又一种可行结构：所述辅助恒扭力发生器10的辅助输出轮13的单向啮合齿为输入锥齿131，所述传动齿盘61的单向传动齿为输出锥齿612，并且所述传动齿盘61与所述辅助输出轮13之间的轴向距离是固定的，此时，在所述输入锥齿131以及输出锥齿612的一侧设有能够径向动作的锥齿盘67，通过外部布置的按钮等操作件连动所述 锥齿盘67，控制锥齿盘67与所述输入锥齿131以及输出锥齿612同时啮合以形成传动，或者同时脱离啮合以断开传动。
如图7所示，可在支架90上固定两个吸盘91，通过吸盘91能够方便地将支架90固定于平滑表面上，此时，通过拉动卷线轮40上的拉绳(配备握把、滑轮)，可利用独立恒扭力发生器30与辅助恒扭力发生器10提供的阻力进行各项健身锻炼动作，具有轻便、省空间、易收纳、成本低、可调节、实时恒力等优点。同时，操作各离合装置60，可使不同数量、不同扭矩的辅助恒扭力发生器10参与工作，提供各级梯度的阻力，适应不同力量基础的训练者的不同要求。
本发明除了应用于健身器，还可应用于机械工业、航天、汽车等技术领域，起到替换重物的技术效果。
以上说明对本发明而言只是说明性的，而非限制性的，本领域普通技术人员理解，在不脱离权利要求所限定的精神和范围的情况下，可作出许多修改、变化或等效，但都将落入本发明的保护范围之内。
