背景技术 Background technique
脉动式无级变速器是由传动机构、 输出机构和调速机构三个基本部分组成 的变速装置。 传动机构将输入轴的匀速转动变为摇杆的往复摆动； 调速机构通 过改变可调曲柄的长度来改变摇杆往复摆动的幅度； 作为输出机构的超越离合 器最后将可调幅的摇杆摆动变为脉动的单向转动输出。  The pulsating continuously variable transmission is a shifting device composed of three basic parts: a transmission mechanism, an output mechanism and a speed governing mechanism. The transmission mechanism changes the constant rotation of the input shaft into the reciprocating swing of the rocker; the speed governing mechanism changes the amplitude of the reciprocating swing of the rocker by changing the length of the adjustable crank; the overrunning clutch as the output mechanism finally swings the adjustable rocker For pulsating one-way rotation output.
脉动式无级变速器传动机构采用几何封闭的低副机构， 因此具有工作可靠、 承载能力高、 变速性能稳定的特点， 其传动机构的设计灵活性大， 可实现大范 围变速的要求， 且最低输出转速可以为零， 可以采用的调速方式较多， 在静止 或运行中均可调速。 此外， 脉动式无级变速器还具有结构简单， 体积较小， 制 造方便和成本较低等优点， 但是其连杆运动时的惯性力难以得到平衡， 不平衡 的惯性力及惯性力矩所引起的振动在高速时会显著增大， 其产生的动载荷还是 造成机械效率较低的重要原因， 此外其输出的脉动性也比较大。  The pulsating continuously variable transmission transmission mechanism adopts the geometrically closed low auxiliary mechanism, so it has the characteristics of reliable operation, high carrying capacity and stable shifting performance. The transmission mechanism has great design flexibility, can realize large-range shifting requirements, and has the lowest output. The speed can be zero, there are many speed control modes that can be used, and the speed can be adjusted during stationary or running. In addition, the pulsating continuously variable transmission has the advantages of simple structure, small volume, convenient manufacture and low cost, but the inertial force during the movement of the connecting rod is difficult to balance, the vibration caused by the unbalanced inertial force and the moment of inertia. It increases significantly at high speeds, and the dynamic load generated by it is also an important cause of low mechanical efficiency, and its output pulsation is also relatively large.
发明内容 Summary of the invention
为了克服现有脉动式无级变速器的惯性力及动载荷大的缺陷， 本发明提供 一种绳索式脉动无级变速器， 该脉动式无级变速器不仅具有现有脉动式无级变 速器的优越性， 而且相对现有脉动式无级变速器具有输入转速高、 惯性力及动 载荷小的特性， 是一种速度高、 运转平稳、 效率高的新机型。  In order to overcome the drawbacks of the inertial force and the dynamic load of the prior art pulsating continuously variable transmission, the present invention provides a rope type pulsating continuously variable transmission which not only has the advantages of the existing pulsating continuously variable transmission, Moreover, the existing pulsating continuously variable transmission has the characteristics of high input speed, inertia force and small dynamic load, and is a new type of high speed, stable operation and high efficiency.
为了达到输入转速高、 惯性力及动载荷小的特性， 本发明提供了一种绳索 式脉动无级变速器， 其所采用的技术方案是： 调速机构上的可调曲柄与输出机. 构的主动环间链接有绳索； 在绳索拉动输出机构主动环作功的相反方向， 输出 机构的主动环与机架间直接或间接链接着弹簧。 上述的绳索可用除绳索外的其 它挠性件来代替， 如钢片、 链条。  In order to achieve the characteristics of high input speed, inertia force and small dynamic load, the present invention provides a rope type pulsating continuously variable transmission, and the technical solution adopted by the invention is: an adjustable crank and an output machine on the speed governing mechanism. The active ring links have a rope; in the opposite direction of the rope pulling the output mechanism active ring, the spring of the output mechanism between the active ring and the frame is directly or indirectly linked. The ropes described above can be replaced by other flexures other than ropes, such as steel sheets and chains.
工作时， 传动机构通过主动轮转动， 由安装在主动轮上的可调曲柄经绳索 拉动输出机构主动环进行前半圈作功， 当主动轮转动到后半圈时， 弹簧拉动输 出机构主动环及绳索往回缩； 调速机构通过改变可调曲柄的位置来改变绳索拉 动输出机构主动环的转动行程； 输出机构通过将可调行程的往复转动变为脉动 的单向转动输出。 该结构改变了传统的连杆式传动， 采用绳索直接带动输出机 构主动环， 其多余约束力少， 往复运动件重量轻、 惯性力小； 而且运动时绳索 及输出机构主动环始终受弹簧牵引着， '减少了因惯性引起的冲击。 During operation, the transmission mechanism is rotated by the driving wheel, and the adjustable crank mounted on the driving wheel pulls the active ring of the output mechanism through the rope to perform the work in the first half circle. When the driving wheel rotates to the second half circle, the spring pulls and loses. The mechanism active ring and the rope are retracted; the speed governing mechanism changes the rotation stroke of the active ring of the rope pulling output mechanism by changing the position of the adjustable crank; the output mechanism changes the reciprocating rotation of the adjustable stroke into a pulsating one-way rotational output . The structure changes the traditional link type transmission, and the rope directly drives the active ring of the output mechanism, and the excess binding force is small, the reciprocating member is light in weight and the inertial force is small; and the active ring of the rope and the output mechanism is always pulled by the spring during the movement. , 'Reduced the impact caused by inertia.
上述的绳索式脉动无级变速器为了平衡惯性力减小输出脉动性， 缩短弹簧 伸缩距离， 采用偶数个输出机构， 且每两个为一组； 每组中的两输出机构相对 传动机构主动轮轴心呈基本对称分布， 各输出机构相对传动机构主动轮的距离 优选为相等； 每组输出机构的两主动环分别在其绳索拉动该主动环作功的相反 方向直接或间接用弹簧相互链接起来。 上述结构每组输出机构两主动环呈相反 方向运动， 并且移动速度相近、 运动体大小及重量相近， 从而使工作时惯性相 互平衡， 减小振动。  The above-mentioned rope type pulsating continuously variable transmission reduces the output pulsation for balancing the inertial force, shortens the spring expansion and contraction distance, uses an even number of output mechanisms, and each of the two is a group; the two output mechanisms in each group are opposite to the transmission mechanism In a substantially symmetrical distribution, the distances of the output mechanisms relative to the drive wheel of the transmission mechanism are preferably equal; the two active rings of each set of output mechanisms are directly or indirectly linked to each other by springs in opposite directions of the rope pulling the active ring. In the above structure, the two active rings of each group of output mechanisms move in opposite directions, and the moving speed is similar, the moving body size and weight are similar, so that the inertia of the working phase is balanced and the vibration is reduced.
上述每组输出机构的两主动环分别在其绳索拉动该主动环作功的相反方向 直接用弹簧相互链接起来的方法， 可采用直接用有弹性的绳索分别将两输出机 构主动环在可调曲柄经绳索拉动输出机构主动环作功的相反方向的一端相互联 接 S来。 每组输出机构的两主动环分别在其绳索拉动该主动环作功的相反方向 间接用弹簧相互链接起来的方法， 可采用直接用绳索经活动滚轮将两输出机构 主动环在可调曲柄经绳索拉动输出机构主动环作功的相反方向的一端相连， 该 活动滚轮用弹簧牵引着， 从而使该活动滚轮始终拉着连接两输出机构主动环的 绳索。 上述两种连结方式利用两输出机构主动环相互牵引其在主动轮转到后半 圈时的回程， 弹簧补偿了两输出机构主动环线速度不同而引起的不同转角牵引 时的长度差， 该结构减少了因牵引弹簧引起的功率损耗， 提高了效率。  The two active rings of each of the above-mentioned output mechanisms are respectively directly linked by springs in the opposite direction of the pulling of the active ring by the ropes, and the two output mechanisms can be directly engaged with the adjustable cranks by directly using elastic ropes. One end of the opposite direction of the work of the active ring of the output mechanism through the rope is coupled to each other. The two active rings of each group of output mechanisms are respectively indirectly linked by springs in the opposite direction of the pulling of the active ring by the ropes, and the two output mechanisms can be directly connected to the adjustable cranks through the ropes through the movable rollers. Pulling one end of the output mechanism active ring in the opposite direction of the work, the movable roller is pulled by the spring, so that the movable roller always pulls the rope connecting the active ring of the two output mechanisms. The above two connection modes utilize the two output mechanism active rings to pull each other back to the rear half of the driving wheel, and the spring compensates for the difference in length of the different angular traction caused by the difference of the active ring speeds of the two output mechanisms, and the structure is reduced. Increased efficiency due to power loss caused by the traction spring.
上述的绳索式脉动无级变速器为了平衡惯性力减小输出脉动性， 缩短弹簧 伸縮距离， 还可采用将两组相同的脉动式无级变速器呈同轴轴向镜像安置， 并 且两个调速机构的位移路径相反、 移动速度同步， 两主动轮转向相同并且同步 转动。  In the above-mentioned rope type pulsating continuously variable transmission, in order to balance the inertial force, the output pulsation is reduced, and the spring expansion and contraction distance is shortened, and two sets of the same pulsating continuously variable transmission can be disposed in a coaxial axial mirror image, and two speed regulating mechanisms are provided. The displacement paths are reversed, the moving speed is synchronized, and the two driving wheels turn the same and rotate synchronously.
为了防止绳索在可调曲柄处弯折， 而引起寿命缩短及功率消耗， 本发明在 可调曲柄上安装有一个带动环。 该带动环的结构是： 其内圆周安装有滚针轴承， 外圆周上开有一个环槽， 在环槽处安装有若干个滚柱， 滚柱可自由回转运动； 该滚柱数量由可调曲柄拉动的绳索而定， 它一般为一个滚柱与一根绳索相连结； 每个相邻滚柱间相对环心的夹角优选为相等， 每个滚柱到环心的距离也优选为 相等。 In order to prevent the rope from being bent at the adjustable crank, resulting in shortened life and power consumption, the present invention has a driving ring mounted on the adjustable crank. The structure of the driving ring is: a needle bearing is mounted on the inner circumference thereof. There is a ring groove on the outer circumference, and a plurality of rollers are installed at the ring groove, and the roller can rotate freely; the number of rollers is determined by the adjustable crank pulling rope, which is generally a roller and a roller The ropes are joined; the angle between each adjacent roller relative to the center of the ring is preferably equal, and the distance from each roller to the center of the ring is also preferably equal.
上述绳索式脉动无级变速器调速机构的可调曲柄的位移可通过伺服电机带 动螺杆， 螺杆推动可调曲柄来改变其相对主动轮轴心的距离。 可调曲柄的位移 也可通过液压或气压直接用油缸或气缸推动， 还可用液压马达或气动马达带动 螺杆推动可调曲柄来实现。 调速机构应用伺服电机作为调速动力源， 其方便远 程及微机控制， 便于实现自动化。  The displacement of the adjustable crank of the above-mentioned rope type pulsating continuously variable transmission governing mechanism can be driven by a servo motor, and the screw pushes the adjustable crank to change the distance from the center of the driving wheel. The adjustable crank displacement can also be directly driven by a cylinder or cylinder by hydraulic or pneumatic pressure, or by a hydraulic motor or a pneumatic motor to drive the screw to push the adjustable crank. The speed governing mechanism uses the servo motor as the speed regulating power source, which is convenient for remote control and microcomputer control, and is convenient for automation.

The adjustable crank moves in the direction of the arrow in the direction of the arrow. When the adjustable crank moves in the upper half (ie, from point a to point b), the overrunning clutch on the right works, and the overrunning clutch on the left is in a disengaged state (in idling).

At the same time, the small steel rope will be pulled around the outer circumference of the overrunning clutch. When the adjustable crank moves to the lower half, the left overrunning clutch is in the working state and the right overrunning clutch is in the disengaged state. The spring can compensate the length difference of the small steel rope when the adjustable crank rotates in the real time, so that the main steel rope and the small steel rope are always under tension.
