Fig. 2 is the cutaway view of Fig. 1
Below in conjunction with accompanying drawing the utility model is described in further detail: present embodiment is under hinge wheel, flywheel, the former driving device situation of chain, on hinge wheel 12, fasten with screws wheel plate 11, refill five cushion blocks that certainly vary in size 27 and be loaded into a circle framework with connecting panel 8, and on connecting panel 8, set up low speed starting, speed increasing force saving systems such as quadrant gear lever 4, roller 6, Connection Block 5, tooth bar 9, spring, three parts of variable-speed gear system and control system are formed.
Its structural relation is to be connected with clutch spindle 2 with axis 1, and clutch spindle 2 usefulness screws and pin are fastened on the axis 1, and concentric with axis 1.Gear 13 is fixed on clutch spindle 2 cylindricals, and fastening with pedal crank 36.Driving gear 3 and axis 1 be bearing fit and with the clutch spindle 2 concentric actions that cooperatively interact, on driving gear 3 end faces denture clutch is arranged, one side of driving gear 3 and 4 engagements of quadrant gear lever, quadrant gear 4 is fixed on the connecting panel 8, contact mutual skid with roller 6 on the Connection Block 5 that is fixed on ratchet outer ring 33 moving, transfers trap 26 to help to regulate the tolerance clearance of wheel plates 11 and ratchet outer ring.The opposite side of driving gear 3 and tooth bar 9 engagements.One end of compression spring 10 is connected with tooth bar 9, and the other end is installed on the axle bed on the connecting panel 8, and ratchet inner ring 34 is fixed on the vehicle body by pawl seat 19.Bearing 30 cooperates fastening with pawl seat by screw thread, packing ring 31 is to regulate axial distance, more than constitutes low speed starting speed increasing force saving system.
Variable-speed gear system is that gear 13 is fastened on the clutch spindle 2 with pedal crank 36, by intermediate gear 14 and gear 15 engagements, gear 15 is fixed on an end of little axle 16, little axle 16 is contained on connecting panel, bearing carrier ring 16a and the bearing carrier ring 16b, bearing carrier ring 16a is fixed on the wheel plate 8, cylindrical roller bearing is housed, and bearing carrier ring 16b is fixed on the wheel plate 11, and a single-row radial ball bearing is housed.Gear 17 is contained in the other end of little axle 16 and meshes with gear ring 18, and gear ring 18 is installed on the pawl seat 19 and constitutes variable-speed gear system.
Control system is to be installed on the slide block 22 by shift fork 20, slide block 22 is installed on the tie bolt 25 that is fixed in vehicle body, pressing plate 24a and pressing plate 24b are fastened on the vehicle body by tie bolt 25, promptly under the triangle crotch of vehicle frame, and reserve the position accurately by centering plate 29.Eccentric shaft 21 is installed on the slide block 22, and pusher dog 28 is installed on the pawl seat 19, draws the end 23 to be connected with eccentric shaft 21, and the other end is connected with control line one end on being fixed on the vehicle frame handgrip.
Principle of work: drive quadrant gear levers 4 and prize hinge wheel 12 and slowly run because of denture clutch axle 2 and transmission gear 3 is housed on the axis of car, meanwhile, driving gear 3 drives tooth bar 9 motions, when tooth bar 9 compression springs 10 arrive to a certain degree, promotes the hinge wheel high speed rotating.With Connection Block that quadrant gear lever 4 is connected on pull back spring 7 is housed, when pedal crank 36 during at the dead point, under the effect of two pull back springs 7, compression spring 10 and extension spring, make driving gear 3, tooth bar 9 and quadrant gear lever 4 homings, when pedal crank is exerted all one's strength once more, what the above-mentioned part on the hinge wheel 12 repeated again moves, and promotes the rotation of hinge wheel, reciprocal always work.In pawl seat and variable speed control mechanism, shift fork 20 and pusher dog 28 and eccentric shaft 21 are housed, to reach the effect that speed change and bicycle fall back flexibly.When people's bicycle or manual tricycle crank throw drive to travel, starting the speed increasing force saving system at a slow speed starts working, reach the purpose of speed increasing force saving, when you drive bicycle or manual tricycle climb very steep slopes when reversing (or want bicycle rear), as long as stir the controller on the handgrip, just become low speed driving, make you cross the abrupt slope easily.
