Principle of work:
Before Brake energy recovery utilizes device work, namely flywheel 1 is in normal rolled state, and now rolling disc drives cylinder 30 to be in contraction state, the not engagement of idle pulley 11 and input gear 12, due to the effect of unilateral bearing 29, the second output gear 28 is also in idling conditions.
When needs braking, deceleration, step on brake pedal, the rolling disc linked with brake actuator drives the electromagnetic valve of cylinder 30 to connect, cylinder rod stretches out, and drives rolling disc 10 to rotate, idle pulley 11 is engaged with input gear 12 and outer end gear 14, the moment of torsion of input and output shaft 6 through gear transmission to whirlpool spring axle, whirlpool spring axle drives the inner of plane scroll spring 22 curling, and the outer end of plane scroll spring 22 is fixed on spring box 21, and spring box 21 is fixed on the top board of device case 7 by locating piece and does not rotate.Through continuing or being interrupted input torque, larger elastic potential energy is stored in spring energy agency.When brake operating cancelled by vehicle, the rolling disc linked with brake actuator drives the closed electromagnetic valve of cylinder 30, and cylinder rod shrinks, and rolling disc 10 is pulled up under the effect of retracing spring 9, now idle pulley 11 and input gear 12 do not engage, and whirlpool spring stored energy mechanism stops energy storage.Ratchet 19, under the effect of ratchet spring, rides on ratchet 17, and owing to storing energy inside plane scroll spring 22, have the trend of reversion, ratchet 19 is stuck on ratchet 17, and prevent whirlpool spring axle reversion, now ratchet drives cylinder 31 to be still in contraction state.In the process of stored energy, if the number of turns that whirlpool spring axle turns over exceedes 95% of the maximum recovery number of turns of plane scroll spring 22, when brake operating still carries out, feed screw nut 23 will contact with energy storage limit switch 24, switch makes rolling disc drive the closed electromagnetic valve of cylinder 30, cylinder rod shrinks, and rolling disc 10 is reset spring 9 pull-up, and stored energy mechanism also stops energy storage.
When needs starting, acceleration, step on the accelerator, the control unit of cylinder 31 is driven to start working with the ratchet driving operating mechanism to realize linking, ratchet drives the electromagnetic valve of cylinder 31 to connect, cylinder rod stretches out, ratchet 19 is forced to depart from ratchet 17, start back to rotate under the torsional interaction that now spring axle in whirlpool stores at plane scroll spring 22, mechanism releases energy, moment of torsion is delivered on input and output shaft 6 by the second output shaft gear 28 and the first output shaft 5, be delivered on flywheel 2 by coupler again, realize the assist function of recuperated energy.The minimum number of turns is less than when plane scroll spring 22 turns to, feed screw nut 23 will contact with releasing energy limit switch 20, switch makes ratchet drive the closed electromagnetic valve of cylinder 31, cylinder rod shrinks, ratchet 19 is stuck on ratchet 17 under the effect of ratchet spring, whirlpool spring axle stops the rotation, and dispose procedure terminates, and the whole feedback of the energy namely exported gives flywheel 2.
