在使用过程中，当输出轴旋转时，由于第一涡卷触发弹簧和第二涡卷触发弹簧与输出轴之间只会接触不会传动力，所以输出轴将不会带动驱动圈、连接盘、连接环、触发筒、支撑环、驱动套运动，从而到达输出轴不会带动驱动套运动的目的；当驱动套旋转时，且当旋转的驱动力较小时，旋转的驱动套将会依次带动支撑环、触发筒、连接环、连接盘、驱动圈、驱动块、第一耳朵形形弹性片与第二耳朵形形弹性片、第一涡卷触发弹簧和第二涡卷触发弹簧、输出轴运动；从而到达驱动套带动输出轴旋转的目的；由于此时的驱动套受到的驱动力较小，所以此时的触发筒将不会沿连接环上所开的内螺纹运动，从而使得双向超越离合器的的转动灵敏度大大提升；当驱动套旋转时，从而驱动套方向看逆时针旋转，且当旋转的驱动力较大时，旋转的驱动套将会依次带动支撑环、触发筒、第二齿条向靠近驱动套方向运动、第二齿轮、支撑轴、第一齿轮、第一齿条将会向远离驱动套方向运动、第三隔板、第二隔板、第一隔板、第二涡卷触发弹簧和第一涡卷触发弹簧将会向远离驱动套方向运动，从而使得第二涡卷触发弹簧位于涂有碳化钨的L2位置处，同时此时的触发筒上的外螺纹也将旋转完，此时的触发筒将会依次带动连接环、连接盘、驱动圈、驱动块、第一耳朵形形弹性片与第二耳朵形形弹性片、第一涡卷触发弹簧和第二涡卷触发弹簧、此时的第二涡卷触发弹簧与输出轴之间存在有压力作用，所以第二涡卷触发弹簧将会带动输出轴逆时针旋转；从而到达驱动套带动输出轴旋转的目的；由于此时的驱动套受到的驱动力较大，双向超越离合器的的转动灵敏度大大减低，但是第二涡卷触发弹簧位于L2位置处，从而使得双向超越离合器的输出轴使用寿命提升；当驱动套旋转时，从而驱动套方向看顺时针旋转，且当旋转的驱动力较大时，旋转的驱动套将会依次带动支撑环、触发筒、第二齿条向靠近驱动套方向运动、第二齿轮、支撑轴、第一齿轮、第一齿条将会向靠近驱动套方向运动、第三隔板、第二隔板、第一隔板、第二涡卷触发弹簧和第一涡卷触发弹簧将会向靠近驱动套方向运动，从而使得第一涡卷触发弹簧位于涂有碳化钨的L2位置处，同时此时的触发筒上的外螺纹也将旋转完，此时的触发筒将会依次带动连接环、连接盘、驱动圈、驱动块、第一耳朵形形弹性片与第二耳朵形形弹性片、第一涡卷触发弹簧和第二涡卷触发弹簧、此时的第一涡卷触发弹簧与输出轴之间存在有压力作用，所以第一涡卷触发弹簧将会带动输出轴顺时针旋转；从而到达驱动套带动输出轴旋转的目的；由于此时的驱动套受到的驱动力较大，双向超越离合器的的转动灵敏度大大减低，但是第一涡卷触发弹簧位于L2位置处，从而使得双向超越离合器的输出轴使用寿命提升。During use, when the output shaft rotates, the output shaft will not drive the driving ring and the connecting plate because the first scroll trigger spring and the second scroll trigger spring will only contact and not transmit force to the output shaft. , connecting ring, trigger cylinder, support ring, and drive sleeve to move, so as to achieve the purpose that the output shaft will not drive the drive sleeve to move; when the drive sleeve rotates, and when the driving force of the rotation is small, the rotating drive sleeve will sequentially drive Support ring, trigger cylinder, connecting ring, connecting plate, driving ring, driving block, first ear-shaped elastic piece and second ear-shaped elastic piece, first scroll trigger spring and second scroll trigger spring, output shaft to achieve the purpose of driving the output shaft to rotate by the drive sleeve; since the driving force received by the drive sleeve at this time is relatively small, the trigger cylinder at this time will not move along the internal thread on the connecting ring, so that the two-way overrunning The rotation sensitivity of the clutch is greatly improved; when the drive sleeve rotates, the direction of the drive sleeve rotates counterclockwise, and when the driving force of the rotation is large, the rotating drive sleeve will sequentially drive the support ring, the trigger cylinder, the second gear The bar moves towards the direction of the drive sleeve, the second gear, the support shaft, the first gear, the first rack will move away from the drive sleeve, the third partition, the second partition, the first partition, the second scroll The scroll trigger spring and the first scroll trigger spring will move away from the drive sleeve, so that the second scroll trigger spring is located at the L2 position coated with tungsten carbide, and at this time the external thread on the trigger cylinder will also move After the rotation is completed, the trigger cylinder at this time will drive the connecting ring, the connecting plate, the driving ring, the driving block, the first ear-shaped elastic piece and the second ear-shaped elastic piece, the first volute trigger spring and the second volute At this time, there is a pressure effect between the second scroll trigger spring and the output shaft, so the second scroll trigger spring will drive the output shaft to rotate counterclockwise; thus achieving the purpose of the drive sleeve to drive the output shaft to rotate; Due to the large driving force received by the drive sleeve at this time, the rotational sensitivity of the two-way overrunning clutch is greatly reduced, but the second scroll trigger spring is located at the L2 position, thereby increasing the service life of the output shaft of the two-way overrunning clutch; when driving When the sleeve rotates, the direction of the drive sleeve rotates clockwise, and when the driving force of the rotation is large, the rotating drive sleeve will sequentially drive the support ring, the trigger cylinder, and the second rack to move towards the direction of the drive sleeve. The gear, the support shaft, the first gear, the first rack will move towards the drive sleeve, the third spacer, the second spacer, the first spacer, the second scroll trigger spring and the first scroll trigger spring It will move closer to the drive sleeve, so that the first scroll trigger spring is located at the L2 position coated with tungsten carbide. At the same time, the external thread on the trigger cylinder will also rotate completely, and the trigger cylinder at this time will be Drive the connecting ring, the connecting plate, the driving ring, the driving block, the first ear-shaped elastic sheet and the second ear-shaped elastic sheet, the first scroll trigger spring and the second scroll trigger spring, and the first scroll trigger spring at this time There is a pressure effect between the volume trigger spring and the output shaft, so the first scroll trigger spring will drive the output shaft to rotate clockwise; thus reaching the drive The purpose of the sleeve to drive the output shaft to rotate; due to the large driving force received by the drive sleeve at this time, the rotation sensitivity of the two-way overrunning clutch is greatly reduced, but the first scroll trigger spring is located at the L 2 position, so that the two-way overrunning clutch The service life of the output shaft is improved.
