Embodiment
The invention will be further described below in conjunction with drawings and Examples.
In conjunction with Fig. 1 and Fig. 2, the present embodiment Vibration of Vehicle Suspensions energy conversion device, its motion changing mechanism 5 is installed in the position (vehicle will no longer need vibration damper after apparatus of the present invention are installed) that has passive spring suspension vehicle vibration damper now by housing 21 outside up and down two mounting holes.The bottom of motion changing mechanism 5 joins with nonspring carried mass 3 by push rod 23 and damping spring 32, sidepiece joins by output shaft 22 and planet gear speed increaser 7, planet gear speed increaser 7 joins with alternator 8, and alternator 8 joins by rectifier 9 and storage battery 10.
In conjunction with Fig. 2, Fig. 3 and Fig. 4, two groups of rack and pinion drive mechanisms are installed in the housing 21 of described motion changing mechanism 5, the tooth bar A24 that wherein is arranged in the one group of rack and pinion drive mechanism in Fig. 2 the right drives the small gear A25 with its engagement, the tooth bar B26 of the one group of rack and pinion drive mechanism in the left side by with the idle pulley 28 driving pinion B27 of its engagement; Tooth bar A24 is identical with tooth bar B26 parameter, and dredges in the middle of taking, and the close change tooth pitch design in two (gear and tooth bar adopt helical tooth) realizes variable ratio; The number of teeth of small gear A25 is greater than the number of teeth of small gear B27; Small gear A25 and small gear B27 are respectively by the identical roller-type one way clutch A31 of structure and overrunning clutch B30 driver output axle 22(as shown in Figure 4); Output shaft 22 front ends and described planet gear speed increaser 7 join, and the rear end is equipped with flywheel energy storage device 29; The lower end of tooth bar A24 and tooth bar B26 and push rod 23 are rigidly connected; Push rod 23 joins by damping spring 32 and nonspring carried mass 3.
The working principle of the present embodiment energy conversion device is:
In the Vehicle Driving Cycle process, the impact that uneven road surface 1 produces wheel 2 is delivered to bearing spring 4 and motion changing mechanism 5 through nonspring carried mass 3, then is delivered to vehicle body 6.Tooth bar A24 in the motion changing mechanism 5 and tooth bar B26 pump under the push rod 23 that pumps drives.
When suspension is compressed, at first compress damping spring 32, then promote connected push rod 23, push rod 23 promotes tooth bar A24 and tooth bar B26 moves upward.Upwards the tooth bar A24 of operation drive small gear A25 clockwise rotates, also clockwise rotate with the outer race 41 of the rigidly connected overrunning clutch A31 of small gear A25, under the effect of spring 43, roller 42 is pushed to the narrow limit of the wedge slot of outer race 41 and hydraulic steering gear adopting cross piece 44 compositions, drives hydraulic steering gear adopting cross piece 44 and clockwise rotates.Hydraulic steering gear adopting cross piece 44 is passed to output shaft 22 with power and is clockwise rotated.
When suspension is stretched, push rod 23 drags tooth bar and moves downward, the small gear of the tooth bar A24 of operation drive downwards A25 rotates counterclockwise, also rotate counterclockwise with the outer race 41 of the rigidly connected overrunning clutch A31 of small gear A25, under the effect of outer race 41, roller 42 is pushed to the broadside of the wedge slot of outer race 41 and hydraulic steering gear adopting cross piece 44 compositions, thereby overrunning clutch is separated, not transferring power.
In like manner, when suspension was compressed, upwards the tooth bar B26 of operation rotated counterclockwise by idle pulley 28 driving pinion B27, and at this moment overrunning clutch B30 separates; When suspension was stretched, the tooth bar B26 of operation clockwise rotated by idle pulley 28 driving pinion B27 downwards, and at this moment overrunning clutch B30 engagement drives output shaft 22 and clockwise rotates.
Like this, no matter suspension is in compression or stretching travel, and output shaft 22 clockwise rotates all the time.The rotation of output shaft 22 improves rotating speed through planet gear speed increaser 7, and 8 generatings of band motor alternator are through backward storage battery 10 chargings of rectifier 9 rectifications.
The change tooth pitch design of dredge in the middle of tooth bar A24 and tooth bar B26 adopt, two is close can improve the travelling comfort of taking.
The number of teeth of small gear A25 can make the damping constant of stretching travel greater than the damping constant of compression stroke greater than the number of teeth of small gear B27, riding comfort to be provided preferably and to control stability.
The below of motion changing mechanism 5 joins by damping spring 32 and nonspring carried mass 3, be based on traditional vibration damper and compare, the rotary inertia of transmission system will be so that the damping hardening of suspension in this energy conversion equipment, reduced the riding comfort of vehicle, can reduce this adverse effect as far as possible by damping spring 32 is installed below motion changing mechanism.
At output shaft 22 rear end Flywheel accumulators 29, can play the effect that in suspension traffic direction change process, reduces the generator speed fluctuation.
Overrunning clutch A31 and overrunning clutch B30 adopt the roller-type one way clutch of small volume can dwindle the volume of motion changing mechanism 5.
