The operation of the drive unit of automatically applying variable torque of the present invention on the output shaft that rotates with constant speed will be described as follows

When the power of this power supply unit 10 outputs 804 horsepowers (HP), as, this power be transmitted respectively 375HP to this input shaft 35 and 429HP to this flywheel 24; Because power is the product of torque and rotating speed, so the rotational speed that this input shaft 35 can 1760rpm and be applied in the torque of a 1119ft-1b.For example, this flywheel 24 can 1760rpm rotational speed and the torque that produces a 1280ft-1b, simultaneously, the power of this input shaft 35 is sent to this output shaft 51 via this belt member 58, just can on this output shaft 51, apply the torque of a 1119ft-1b, and make the rotational speed of this output shaft 51 with 1760rpm.Therefore, the torque of a 1119ft-1b is rotated and be applied in to the speed that the armature shaft 611 of this generator 60 can 1760rpm.When this generator 60 needs big power, as: during 750HP, the torque that the rotating speed of this input shaft 35 will reduce to 880rpm and apply a 2238ft-1b is on this output shaft 51; At this moment, the rotating speed of flywheel 24 reduces to 880rpm and is dragged the torque that adds 1119ft-1b, so that the power that disengages 375HP via this input shaft 35 is to this output shaft 51, and can not increase the power output of this power supply unit 10; At the same time, because of the rotating speed of the second half ones 42 reduces, the centrifugal force thereby the minimizing of the ball 46 in these guide grooves 45, these balls 46 will be pushed to input shaft 35 by described helical spring 47, shown in Figure 12,13.Therefore, this second half one 42 will be pushed to the first half ones 401 by the angular force of this first spring component 48, increase the effective diameter of the first variable-diameter pulley 40 by this.For keeping belt tension, first and second half one 52 and 53 can overcome this second spring component 56 and 57 angular force and mutually away from, promptly reduce the effective diameter of this second variable-diameter pulley 50, as shown in figure 12.The result, the rotating speed of this output shaft 51 can not reduce because of the increase of the torque that is applied thereto, and can maintain 1760rpm, so, this output shaft can be exported the power of 750HP, when the torque that applies a 2238ft-1b still can keep the fixed rotating speed of its 1760rpm thereon the time.

When the power of generator 60 reduces, unnecessary power will be sent to this flywheel 24, and the rotating speed of flywheel 24 and input shaft 35 will increase simultaneously.Therefore, the effective diameter of this input shaft 35 will reduce; Because of this first and second half one 401,42 moves apart the centrifugal force of the described ball 46 of mat mutually, the effective radius of this output shaft 51 then reduces; Mode according to this, the rotating speed of this output shaft 51 can be maintained fixed.In addition, when unnecessary power is sent to this flywheel 24 by this output shaft 51, the torque that is applied on this input and the output shaft 35,51 will reduce.

It should be noted when the power of this generator changes that at this this flywheel 24 will transmit power to this output shaft 51 by this input shaft 35, and receive the power variation that remedies output shaft 51 from the power of output shaft 51.Therefore, the power of this power supply unit 10 does not need to increase or reduce and can keep a fixed rotating speed of the output shaft 51 of this torque converter 20, therefore can reach purpose of the present invention.

Please consult Fig. 1 again, this generator 60 is arranged near these torque converter 20 places, and this generator 60 has an armature 61 to be provided with wherein.This armature is positioned at a magnetic field, and an armature shaft 611 is arranged, and this armature shaft connects this output shaft 51 and this armature 61.Therefore, this armature 61 can be output axle 51 and rotate continuously with a fixing speed, and therefore, an electric current can be exported via this armature 61 continuously from this generator 60; One power regulator 64 is electrically connected with the armature 61 of this generator 60, and this power regulator 64 is provided with a transformer 66, so that export stable predetermined voltage in known manner.Voltage stabilizing transducer 65 has a control circuit 67, and it is connected with this power regulator 64, therefore, and can be by this voltage stabilizing transducer 65 outputs one fixed current.
