In this example, the stored energy torsion spring 12 is released at an angle of 43 ° for a release time of about 2s.
The invention is divided into two working modes: and the high-speed direct drive and low-speed energy storage are intensively output.
The principle of high-speed direct drive is as follows:
when the rotation speed of the input shaft 17 is higher, the sliding sleeve 15 moves towards the direction of the output shaft clutch wheel 14 through the mode switching mechanism, so that the second end tooth 1401 is meshed with the first sliding sleeve end tooth 1501, the output shaft 1 and the input shaft 17 rotate together at the moment, the direct driving aim is achieved, and the output large gear 13 is sleeved on the output shaft 1 in an empty mode, and the input small gear 16 is sleeved on the input shaft 17 in an empty mode, so that rotation cannot occur, and the intermediate shaft 9 is kept motionless; when the output shaft 1 rotates the inner race 302 of the overrunning clutch 3 in the forward direction, the ratchet 11 does not start to rotate because the inner race 302 rotates at a higher speed than the outer race 301 due to the characteristics of the overrunning clutch 3.
The principle of low-speed energy storage centralized output is as follows: when the rotation speed of the input shaft 17 is lower, the sliding sleeve 15 moves towards the direction of the input pinion 16 through the mode switching mechanism, so that the first end tooth 1601 is meshed with the second sliding sleeve end tooth 1502, at the moment, the input shaft 17 drives the input pinion 16 to rotate, and the output pinion 13 is driven to rotate through the intermediate pinion 8 and the intermediate large gear 10 on the intermediate shafts 9 and 9, the output large gear 13 is sleeved on the output shaft 1, so that the output shaft 1 cannot rotate, in the rotation process of the output large gear 13, the pawl 5 is limited to rotate under the action of the compression torsion spring 4 under the action of the compression torsion spring 11, therefore, the energy storage torsion spring 12 arranged between the output large gear 13 and the ratchet 11 stores energy, when the deflector rod 7 on the output large gear 13 rotates to be in contact with the pawl arm 501, the pawl 5 rotates around the support frame 6, the limit of the ratchet 11 is eliminated, in this state, the energy is released by the energy storage torsion spring 12, at the moment, the outer ring 301 of the overrunning clutch 3 rotates, due to the characteristic of the overrunning clutch 3, the overrunning clutch 3 is positively and the rotation speed of the output large gear 13 is positively and is greatly increased to the limit the overrunning torsion spring 302, and the overrunning clutch 11 rotates to the overrunning clutch 11, and is completely released from the overrunning clutch 11 to the position of the overrunning clutch 11, and the overrunning clutch 11 rotates to the overrunning clutch 11, thereby the overrunning clutch 11 is completely and completely rotates in the mode of the speed 11, and is completely and has the speed-limited by the speed of the ratchet rod 11 when the overrunning rod 11 is released from the overrunning clutch 11.
The principle of the mode switching mechanism is as follows:
the photoelectric sensor 23 is used for sensing photoelectric signals reflected on the reflecting column 24, the angular speed of the input shaft 17 can be calculated by means of a single chip microcomputer through sensing the interval time t of the photoelectric signals reflected on the reflecting column 24 twice, the angular speed value is calculated, the input speed is judged (a preset judging value is high speed when the input speed is higher than the judging value and low speed when the input speed is lower than the judging value) through the calculated angular speed value, and the single chip microcomputer controls the expansion and contraction of the electric push rod 19 through the high and low speed judgment, so that the sliding sleeve 15 is driven to horizontally move on the input shaft 17;
in addition, a limiting plate 21 is arranged at the lower end of a shifting fork 20 at the end part of the electric push rod 19, and distance sensors 22 are arranged at two sides of the limiting plate 21 along the axial direction of the input shaft 17 and used for limiting the maximum stroke of the sliding sleeve 15, and the starting and stopping of the electric push rod 19 are controlled by signals sent by the distance sensors 22 so as to achieve the protection purpose of the sliding sleeve 15 and the electric push rod 19.
