工作原理：working principle:
假设平衡支架7、第二行星齿轮机构行星齿轮支架3与调节行星齿轮机构太阳轮18不转。当输入轴2带动第一行星齿轮机构太阳轮4正方向转动时，第一行星齿轮机构太阳轮4带动第一行星齿轮机构行星齿轮21自转同时反方向公转，并会在第一行星齿轮机构行星齿轮与调节行星齿轮机构行星齿轮共用轴6上产生一个正方向公转的力，这个力通过调节行星齿轮机构行星齿轮19与调节行星齿轮机构太阳轮18的作用会在调节行星齿轮机构太阳轮18上产生一个更大扭矩正方向转动的力，第一行星齿轮机构行星齿轮21反方向公转会加快第一行星齿轮机构齿圈20反转的速度，第一行星齿轮机构齿圈20反转通过第一轴套24带动第二行星齿轮机构太阳轮26反方向转动，第二行星齿轮机构太阳轮26通过第二行星齿轮机构行星齿轮23带动第二行星齿轮机构齿圈22正方向转动并减速，第二行星齿轮机构齿圈22带动第二轴套25正方向转动，此时第二轴套25作为输出端输出为减速后的大扭矩，同时第二行星齿轮机构太阳轮26通过第二行星齿轮机构行星齿轮23给了第二行星齿轮机构行星齿轮支架3一个反方向转动的力，这个反方向转动的力通过第二行星齿轮机构行星齿轮支架3与平衡端支架7与调节行星齿轮机构太阳轮18上面正方向转动的力大小相等方向相反形成平衡，所以平衡支架7、第二行星齿轮机构行星齿轮支架3与调节行星齿轮机构太阳轮18不转，这时只要很小的力就能打破平衡使其转动，通过改变这个力的大小就能控制第二行星齿轮机构行星齿轮支架3与平衡端支架7与调节行星齿轮机构太阳轮18的方向与转速，从而控制作为输出端的第二轴套25转动的方向与速度，当平衡支架7与第二行星齿轮机构行星齿轮支架3静止时第二轴套25转速较低，当平衡支架7与第二行星齿轮机构行星齿轮支架3正方向转动并越转越快时第二轴套25就越转越快，直到输入轴2与平衡支架7与第二轴套25达到相同速度。当平衡支架7与第二行星齿轮机构行星齿轮支架3反方向转动的速度与输入轴2正方向转动的速度匹配时，作为输出端的第二轴套25不转就形成离合器的功能。Assume that the balance bracket 7, the second planetary gear mechanism planetary gear carrier 3 and the adjustment planetary gear mechanism sun gear 18 do not rotate. When the input shaft 2 drives the sun gear 4 of the first planetary gear mechanism to rotate in the positive direction, the sun gear 4 of the first planetary gear mechanism drives the planetary gear 21 of the first planetary gear mechanism to rotate and revolve in the opposite direction at the same time. The gear and the planetary gear of the adjusting planetary gear mechanism share a shaft 6 to generate a positive revolution force, which will act on the sun gear 18 of the adjusting planetary gear mechanism through the action of the planetary gear 19 of the planetary gear mechanism and the sun gear 18 of the planetary gear mechanism A greater torque is generated to rotate the force in the positive direction, and the planetary gear 21 of the first planetary gear mechanism revolves in the opposite direction, which will speed up the speed at which the ring gear 20 of the first planetary gear mechanism reverses, and the ring gear 20 of the first planetary gear mechanism reverses through the first The shaft sleeve 24 drives the sun gear 26 of the second planetary gear mechanism to rotate in the reverse direction, and the sun gear 26 of the second planetary gear mechanism drives the ring gear 22 of the second planetary gear mechanism to rotate in the forward direction and decelerates through the planetary gear 23 of the second planetary gear mechanism. The ring gear 22 of the planetary gear mechanism drives the second bushing 25 to rotate in the positive direction. At this time, the second bushing 25 is used as the output end to output a large torque after deceleration. At the same time, the sun gear 26 of the second planetary gear mechanism passes through the planet The gear 23 gives the planetary gear support 3 of the second planetary gear mechanism a force to rotate in the opposite direction. The force that rotates in the positive direction is equal in size and opposite in direction to form a balance, so the balance bracket 7, the second planetary gear mechanism planetary gear bracket 3 and the adjustment planetary gear mechanism sun gear 18 do not rotate, and at this time as long as a small force can break the balance and make it Rotate, just can control the second planetary gear mechanism planetary gear bracket 3 and the balance end bracket 7 and adjust the direction and the rotating speed of the planetary gear mechanism sun gear 18 by changing the size of this force, thereby controlling the rotation of the second shaft sleeve 25 as the output end Direction and speed, when the balance bracket 7 and the planetary gear bracket 3 of the second planetary gear mechanism are stationary, the second shaft sleeve 25 rotates at a lower speed, and when the balance bracket 7 and the second planetary gear mechanism planetary gear bracket 3 rotate in the positive direction When fast, the second shaft sleeve 25 turns faster and faster until the input shaft 2 and the balance bracket 7 reach the same speed with the second shaft sleeve 25 . When the speed at which the balance bracket 7 and the second planetary gear mechanism planetary gear carrier 3 rotate in the opposite direction matches the speed at which the input shaft 2 rotates in the forward direction, the second shaft sleeve 25 as the output end will form a clutch function without turning.
变速器工作时由于齿轮啮合传动中的损耗，作用在第二行星齿轮机构行星齿轮支架3上面反方向转动的力会小于调节行星齿轮机构太阳轮18上面正方向转动的力，这样调节行星齿轮机构太阳轮18与平衡支架7与第二行星齿轮机构行星齿轮支架3就会自行正转，这时只用由刹车片13和刹车盘16组成的阻尼器就能控制变速。也可在设计时使调节行星齿轮机构太阳轮18上正方向的力略大于第二行星齿轮机构行星齿轮支架3上反方向的力，这样就能保证输入轴2与第二轴套25与平衡支架7与第二行星齿轮机构行星齿轮支架3达到一比一的最高变速比，也能保证平衡支架7、第二行星齿轮机构行星齿轮支架3与调节行星齿轮机构太阳轮18不会自行反转。Due to the loss in the gear meshing transmission when the transmission works, the force acting on the planetary gear carrier 3 of the second planetary gear mechanism to rotate in the opposite direction will be less than the force to adjust the positive direction of the sun gear 18 of the planetary gear mechanism, so that the sun gear of the planetary gear mechanism can be adjusted Wheel 18 and balance support 7 and the second planetary gear mechanism planetary gear support 3 will rotate forward voluntarily, at this moment only just can control speed change with the damper that is made up of brake pad 13 and brake disc 16. It is also possible to adjust the force in the positive direction on the sun gear 18 of the planetary gear mechanism slightly greater than the force in the opposite direction on the second planetary gear mechanism planetary gear support 3 during design, so that the input shaft 2 and the second shaft sleeve 25 are in balance with each other. The bracket 7 and the planetary gear bracket 3 of the second planetary gear mechanism reach the highest gear ratio of one to one, which can also ensure that the balance bracket 7, the planetary gear bracket 3 of the second planetary gear mechanism and the sun gear 18 of the adjusting planetary gear mechanism will not reverse by themselves .
当变速器工作时输入轴2同时带动第三行星齿轮机构太阳轮11正方向转动时，此时刹车盘16被刹车片13锁死，副轴14与第三行星齿轮机构行星齿轮支架10不转动，第三行星齿轮机构太阳轮11通过第三行星齿轮机构行星齿轮9带动第三行星齿轮机构齿圈8反方向转动，第三行星齿轮机构齿圈8带动平衡支架7、调节行星齿轮机构太阳轮18、第二行星齿轮机构行星齿轮支架3反方向转动，此时第三行星齿轮机构齿圈8与平衡支架7、调节行星齿轮机构太阳轮18、第二行星齿轮机构行星齿轮支架3反方向的转速与变速器在离合器分离工作状态时平衡支架7、调节行星齿轮机构太阳轮18、第二行星齿轮机构行星齿轮支架3反方向的转速相同，这样就实现了离合器的功能。When the transmission is working, the input shaft 2 simultaneously drives the sun gear 11 of the third planetary gear mechanism to rotate in the positive direction. At this time, the brake disc 16 is locked by the brake pads 13, and the auxiliary shaft 14 and the planetary gear carrier 10 of the third planetary gear mechanism do not rotate. The sun gear 11 of the third planetary gear mechanism drives the ring gear 8 of the third planetary gear mechanism to rotate in the opposite direction through the planetary gear 9 of the third planetary gear mechanism, and the ring gear 8 of the third planetary gear mechanism drives the balance bracket 7 and adjusts the sun gear 18 of the planetary gear mechanism 1. The second planetary gear mechanism planetary gear support 3 rotates in the opposite direction. At this time, the third planetary gear mechanism ring gear 8 and the balance support 7 adjust the rotation speed of the planetary gear mechanism sun gear 18 and the second planetary gear mechanism planetary gear support 3 in the opposite direction. When the speed changer is in the clutch separation working state, the rotating speed of the balance bracket 7, the planetary gear mechanism sun gear 18, and the second planetary gear mechanism planetary gear carrier 3 opposite directions is the same, so the function of the clutch has been realized.
变速器工作时在平衡支架7、调节行星齿轮机构太阳轮18、第二行星齿轮机构行星齿轮支架3上会有一个正方向转动的力，这个力会作用在第三行星齿轮机构齿圈8上，所以当刹车盘16阻力变小时，在第三行星齿轮机构太阳轮11与第三行星齿轮机构齿圈8共同力的作用下第三行星齿轮机构行星齿轮支架10会正方向转动，此时第三行星齿轮机构齿圈8、平衡支架7、第二行星齿轮机构行星齿轮支架3反方向的转速减小，第二轴套25开始正方向转动并输出大扭矩低转速的力。当刹车盘16阻力不断变小时第三行星齿轮机构行星齿轮支架10会正方向越转越快，第三行星齿轮机构齿圈8会从反方向转动到静止再到正方向转动，并且正方向转动的速度越来越快，此时变速器第二轴套25其正方向的转速就会越转越快直到与输入轴2速度相同。这样通过增加第三行星齿轮机构30的方式，只用由刹车片13和刹车盘16组成的阻尼器就能同时控制实现离合器的功能与控制变速的功能。通过输出轴套25的方式实现了输入轴与输出端在同一端的功能。When the transmission is in operation, there will be a force rotating in the positive direction on the balance bracket 7, adjusting the sun gear 18 of the planetary gear mechanism, and the planetary gear carrier 3 of the second planetary gear mechanism, and this force will act on the ring gear 8 of the third planetary gear mechanism. Therefore, when the resistance of the brake disc 16 becomes smaller, the planetary gear support 10 of the third planetary gear mechanism will rotate in the positive direction under the joint force of the sun gear 11 of the third planetary gear mechanism and the ring gear 8 of the third planetary gear mechanism. The rotation speeds of the ring gear 8 of the planetary gear mechanism, the balance bracket 7, and the planetary gear bracket 3 of the second planetary gear mechanism decrease in the opposite direction, and the second shaft sleeve 25 starts to rotate in the positive direction and outputs the power of high torque and low speed. When the resistance of the brake disc 16 keeps decreasing, the planetary gear carrier 10 of the third planetary gear mechanism will rotate faster and faster in the positive direction, and the ring gear 8 of the third planetary gear mechanism will rotate from the reverse direction to stationary and then rotate in the positive direction, and rotate in the positive direction. The speed is getting faster and faster, and now the speed changer second shaft sleeve 25 in its positive direction will turn faster and faster until it is the same as the input shaft 2 speed. In this way, by adding the third planetary gear mechanism 30, only the damper composed of the brake pad 13 and the brake disc 16 can be controlled to realize the function of the clutch and the function of controlling the speed change simultaneously. The function that the input shaft and the output end are at the same end is realized by means of the output shaft sleeve 25 .
