[0042] 当可变链轮板560在主动传动装置500和从动传动装置700上形成的圆的直径相同时,包裹在主动传动装置500和从动传动装置700上的可变链轮板560的长度也相等;当包裹在主动传动装置500上的钢带直径最大时、包裹在从动传动装置700上的钢带直径最小,反过来也一样。 [0042] When the diameter of the variable sprocket circle plate 560 formed on the active gear 500 and the driven gear 700 are the same, the variable sprocket wrap 560 on the plate 500 and the active gear 700 of the driven gear also equal length; when the maximum diameter of the strip when wrapped in the active gear 500, the minimum diameter of the steel strip wrapped on the driven gear 700, and vice versa.

[0043]可变链轮板560的外侧固定连接有可变链轮齿410,并且把主动传动装置500和从动传动装置7〇〇分别每隔3〇°角安装有一个卡爪f510,共计I2个卡爪510,其中一个卡爪510焊接至可变链轮板560,相邻的两个卡爪510间的距离就会随着主动传动装置500和从动传动装置700的改变而改变。 Outer [0043] The variable plate 560 is fixed to a sprocket connected to the variable sprocket 410, and the active gear 500 and the driven gear is mounted 7〇〇 3〇 ° angle intervals and a pawl f510, total I2 a pawl 510, wherein a distance between a pawl 510 welded to the plate 560 of the variable sprocket, the adjacent two jaws 510 will change as the transmission apparatus 500 and the driven gear 700 is changed actively. 可变链轮齿410作为“齿”可以在可变链轮板560的直径变化(随意变大或变小)时保证可变链轮齿410和链条430的啮合。 Variable sprocket 410 as the "teeth" to ensure the engagement of the chain 410 and the sprocket tooth variable 430 changes the variable diameter sprocket plate 560 (larger or smaller random).

[0045]主动传动装置500和从动传动装置7〇〇调节可变链轮板560直径的运动独立于机械式可变链轮无级变速器900输入输出的动力传递,其原理相同。 [0045] The active gear 500 and the driven gear 7〇〇 adjusting variable diameter sprocket wheel movement independent of plate 560 to the power sprocket variable mechanical CVT 900 input and output transfer, the same principle.

[0046]具体地,通过主动传动装置500、从动传动装置700以及链条430传输动力的输入和输出,通过可变链轮齿410和链条430之间的齿面啮合方式进行速度和动力的传递,从而传输发动机输入的动力。 [0046] In particular, by active transmission 500, the driven gear 700 and a chain 430 for transmitting power input and output devices, for speed and power transmission by way of the engagement between the tooth surfaces 430 of the variable chain and the sprocket 410 , so that the transmission of the engine power input. 输入主轴230通过花键与卡盘540连接,输入主轴230与卡盘540同步转动。 Input shaft 230 is splined to the chuck 540 is connected to the input shaft 230 and the chuck 540 synchronous rotation.

[0047] 可变链轮板560的直径调节独立于卡盘540的转动。 [0047] The variable diameter sprocket adjustment plate 560 is rotatable independently of the chuck 540.

[0048] 通过机械式可变链轮无级变速器900箱体100内的两个伺服器800控制主动传动装置和从动传动装置700之间的无级变速。 [0048] The continuously variable transmission of the variable sprocket housing 900 through two mechanical control server 800 in the CVT 100 between the active device 700 and a driven gear. 应理解,伺服器800可以是伺服电机、步进电机或其它类型的电机。 It should be understood, the server 800 may be a servo motor, stepper motor or other type of motor. 在本实施例中,由于主动传动装置500安装于隔板130,从动传动装置700安装于箱体100的侧壁110,主动传动装置500和从动传动装置700相对设置,主动传动装置5〇〇和从动传动装置700的是通过链条430来传递转速和转向。 In the present embodiment, since the active gear 500 is attached to the partition plate 130, the driven gear 700 is attached to the housing sidewall 110 100, the active gear 500 and the driven gear 700 is disposed opposite to the active transmission 5〇 square and the driven gear 700 is transmitted to the speed and direction by a chain 430.

[0049] 这两个伺服器800是用作独立控制主动传动装置500和从动传动装置700中的可变链轮板560,分别调节主动传动装置500的可变链轮板560的直径以及从动传动装置700的可变链轮板560的直径。 [0049] The server 800 is used as two independent control variable active drive sprocket 500 and the driven gear 700 in the plate 560, respectively, adjusting the diameter of the variable sprocket active plate actuator 560 and 500 from moving the variable diameter drive sprocket 560 of the plate 700. 应理解为,在主动传动装置500和从动传动装置700的转向相同的实施例中,这两个伺服器800的转向是一正一反同步运行的,g卩主动传动装置500的可变链轮板560的直径变大时从动传动装置700的可变链轮板560的直径同步变小,主动传动装置500的可变链轮板560的直径变小时从动传动装置700的可变链轮板560的直径同步变大。 To be understood as the active gear 500 and the driven gear 700 of the steering apparatus in the same embodiment, both the server 800 is a positive and negative steering synchronous operation, variable chain transmission 500 g of active Jie diameter driven gear wheel plate of the variable plate 700 of the sprocket 560 in synchronization becomes smaller diameter 560 becomes large, variable chain 560 becomes small diameter gear driven sprocket active variable transmission device 700 of the plate 500 diameter of the wheel plate 560 becomes large in synchronization.

[0052] 基本原理为:电子调速系统通过伺服器800上的小齿轮啮合备件电盘垫齿盖板1, 因为备件电盘垫齿盖板1与备件电盘垫齿板2为螺栓固定,动力啮合传递到备件行星轮3,再到备件太阳轮4,而备件太阳轮4的内齿又与伺服轴5的外齿相啮合,而伺服轴5的内腔通过保持架10的轴承与输入主轴230滑动相连,又支持它单独运作,而伺服轴5的另一端的外齿与太阳轮6相啮合,而太阳轮6又与行星轮7相啮合,因行星轮7的齿轮厚度跨电盘垫齿板8与盘丝牙盘550两齿的厚度,并与两齿同时啮合,而电盘垫齿板8与卡盘540为螺栓固定,盘丝牙盘550与卡盘540为可自由转动,电盘垫齿板8与盘丝牙盘550两齿有齿数差,故当行星轮7 旋转一周时,盘丝牙盘550就会比电盘垫齿板8及卡盘540多或少转一齿的距离,所以电子调速系统可以通过伺服器S00上的正转反转,及转速的快慢来调节盘丝 [0052] The basic principle is: the electronic speed control system by a cover mat tooth pinion power spare disk on the server 800, because the spare boards and spare pad electrically tooth plate 1 plate 2 plate spacer bolts teeth, engaging the power transmitted to the planetary gear 3 spare parts, spare parts and then to the sun gear 4, the sun gear and the internal teeth 4 spare turn mesh with external teeth of the servo shaft 5, the servo axis of the input cavity 5 via a bearing retainer 10 the spindle 230 is slideably coupled to, and to support it operates alone, and the other end of the servo shaft 5 of the outer teeth of the sun gear 6 is engaged, the sun gear 6 and engaged with the planet gear 7, because the gear thickness of the planet wheels 7 across the boards mat tooth plate 8 and the plate wire teeth disc thickness 550 two teeth, and engages simultaneously with two teeth, while the boards pads tooth plate 8 and the chuck 540 is bolted plate wire crankset 550 and the chuck 540 is free to rotate , boards pads tooth plate 8 and the plate wire 550 tooth plate has two teeth difference between the number of teeth, so that when the revolution of the planetary gear 7, the disc tray 550 will pad wire teeth of the tooth plate 8 and the chuck disk 540 more or less than the electric switch distance of a tooth, it may forward the electronic speed control system on the reverse by the server S00, and the rotational speed of the disc speed is adjusted wire 牙盘550上的阿基米德螺线渐开线盘丝平面螺纹,而卡爪510的平面螺牙又与之啮合,使卡爪510在卡盘540的半径方向运动,从而改变可变链轮板560的直径。 On Archimedes spiral involute tooth plate 550 flat plate wire thread and the thread 510 of the plane of the pawl and engaged therewith, so that the jaws 540 move in a radial direction of the chuck 510, thereby changing the variable chains the diameter of the wheel plate 560.

[0053]在伺服器800端传感器测得卡盘540的转速后,再加上当主动传动装置500和从动传动装置7〇〇中的可变链轮板560为直径相同时,其转速也相同。 [0053] After the server 800 ends the chuck rotation speed measured by the sensor 540, taken together with the active gear 500 and the driven gear sprocket 7〇〇 the variable plate 560 is the same diameter, which is the same rotational speed .

[0054]假设主动传动装置5〇〇中的盘丝牙盘550比卡盘540多或少转一齿牙的距离,也就是在伺服器800的转速比卡盘540的转速每多转一圈为(0.25mm/圈),那么假设当主动传动装置5〇〇中的卡盘540转速为1000转时,伺服电机转速为11〇〇转,则可变链轮板560的半径就变大了25臟,从动传动装置700则相反,伺服电机转速为900转,则可变链轮板560的半径就变小了25mm。 [0054] Suppose the disc plate wire 550 tooth gear 5〇〇 active in a transfer distance of the teeth more or less than the chuck 540, the server 800 is the rotational speed ratio of the rotational speed of the chuck 540 revolutions per revolution of the multi- is (0.25mm / circle), then it is assumed when the active transmission 5〇〇 a chuck 540 rotation speed is 1000 rpm, the servo motor speed is 11〇〇 turn radius of the variable plate 560 of the sprocket becomes bigger 25 dirty, opposite the driven gear 700, the servo motor speed is 900 rpm, the variable radius of the sprocket plate 560 becomes small 25mm. 而作为中间传输带的链条430的周长始终不变,从而改变机械式可变链轮无级变速器900的传动比。 As the circumference of the intermediate transfer belt 430 is always the same chain, thereby changing the mechanical continuously variable drive ratio variable sprocket 900.

[0055]伺服器S00通过驱动电盘垫齿板来驱动盘丝牙盘550。 [0055] The server S00 mat tooth plate drive disc 550 by the disc drive tooth wire boards. 具体地,调速是由伺服电机来控制高速转动中的主动传动装置500和从动传动装置700的卡盘540体内的盘丝牙盘550, 盘丝牙盘550做自定心及变距大小半径动作,通过固定装载在卡爪510上的可变链轮560做大小直径的无级变化,从而使可变链轮板560与滚子链之间产生啮合传输运动。 In particular, speed is controlled by the servo motor rotates at high speed in the active gear 500 and the driven gear 700 of the chuck body plate wire 540 tooth plate 550, the disc tray 550 wire teeth made self-centering and pitch size the radius of action, mounted on the fixed jaw 510 of the variable sprocket 560 made infinitely variable size diameter, so that the variable plate 560 and the sprocket roller chain meshing engagement between the motion transfer.

[0056] 应理解,在其它实施例中,伺服器800可以直接驱动盘丝牙盘550,盘丝牙盘550驱动卡爪510,卡爪510带动可变链轮板560以改变可变链轮板560的直径;伺服器800还可以通过其它传动系统直接地或间接地驱动盘丝牙盘500。 [0056] It should be understood that in other embodiments, the server 800 may directly drive plate wire teeth plate 550, the disc 550 disc drive wire teeth pawl 510, the pawl 510 driven by a variable plate 560 to change the variable sprocket sprocket diameter of the plate 560; server 800 can also drive disk or indirectly through other wire teeth disc drive system 500 directly.

[0057]在一个示例中,输入装置200转动1000转,则伺服器800端传感器测得转速约为51 转左右与之同步,只要伺服器800转动的转速大于51转或小于51转都会使主动传动装置500 或从动传动装置700上的可变链轮板560的直径变大或变小,假设主动传动装置500的可变链轮板560的最小直径变为100mm,而此时的从动传动装置700上的可变链轮板560的最大直径变为200mm。 [0057] In one example, the input device 200 rotates 1000 revolutions, the server end of the sensor 800 to obtain the measured speed is about 51 rpm or so synchronized, the server 800 as long as the rotation speed is greater than or less than 51 rpm will cause the switch 51 active or a variable diameter drive sprocket 500 on the plate 560 driven transmission device 700 becomes larger or smaller, assuming a minimum diameter sprocket active variable transmission device 560 of plate 500 becomes 100mm, at which point the follower the maximum diameter of the variable plate 560 on the sprocket gear 700 becomes 200mm. (电调控制系统是预设定程序控制的)以最小直径到最大直径为l〇〇mm的变动,假设主动传动装置500中的盘丝牙盘550在伺服电机比主动传动装置500转速每多转一圈为(0.25mm/圈),那么当主动传动装置500转速为1000转时,而伺服电机转速为1151转时(极限),主动传动装置500上的可变链轮板560的直径就为最大,直径变为200mm,而同时由于伺服电机对从动传动装置700上的可变链轮板560是反转的,则从动传动装置700上的可变链轮板560的直径就为最小,直径变为100mm,而主动传动装置500上的转速则可降下来了。 (ESC control system is programmed to pre-set) minimum diameter to a maximum diameter variation l〇〇mm, assuming that the active transmission wire 500 tooth plate 550 in each of the servo motor 500 speed than active transmission of revolution (0.25mm / circle), then the diameter of the device 500 when the active transmission speed is 1000 rpm, while the servo motor speed is 1151 rpm (limit), the variable plate 500, a sprocket gear 560 on the active the maximum diameter becomes 200mm, while the servo motor due to a variable plate on the driven sprocket gear 700 is inverted 560, the variable diameter of the driven sprocket 560 on the plate 700 on the transmission of the minimum diameter becomes 100mm, and the active gear 500 on the rotation speed may drop down.
