Abstract
The utility model relates to a flywheel driving mechanism for bicycles. The utility model improves a driving mechanism that a flywheel drives a wheel hub. The utility model can relieve persons' fatigue and the weak feeling of two legs when persons ride bicycles, especially persons riding bicycles in long distance, or riding the bicycles to climb hills. The utility model is characterized in that a spring seat and a disc type spring are arranged between the flywheel and the wheel hub; the inner end of a disk type spring is fixedly connected with the spring seat by a force transmission disc; the outer end of the disc type spring is fixedly connected with the force transmission disc; the spring seat is connected with the flywheel; the force transmission disc is connected with the wheel hub. The utility model has the advantages that the disk type spring is rotated and is screwed tightly when the rotation of the flywheel is driven by a foot pedal, and simultaneously, the disc type spring stores energy; the disc type spring releases the energy which is stored momentarily in order to provide boosting force for the foot pedal when the utility model is used for riding in long distance or is used for and riding the bicycles to climb hills. Hence, the fatigue can be reduced under the condition of riding the bicycles, and a person has an easy feeling in two legs. The utility model is used as a flywheel driving mechanism for bicycles.
Description
Technical field: the invention is the improvement that bicycle freewheel is driven the transmission device of wheel hub.
Background technology: present employed bicycle is that flywheel is installed on wheel hub, the foot-operated flywheel that drives rotates, flywheel drives the wheel hub rotation, bicycle when long distance is ridden or climbing when riding, wants to keep original speed to overtake, have only by firmly foot-operated, maintain speed to consume one's strength, people can be tired as a result for it, and the unable sensation of both legs is arranged.
Summary of the invention: the invention is exactly by bike a human-body fatigue problem in the time of will solving long distance or climbing, alleviate the unable sensation of both legs, be achieved through the following technical solutions: bicycle freewheel transmission device: comprise flywheel, wheel hub, the axle bowl, steel ball, the axle shelves, nut, it is characterized in that the chain wheel on the flywheel makes in the outer end of Case of fly-wheel, the cover inner termination is made bulge loop in the flywheel, its outer round surface is made screw thread, and be connected with spring abutment, be enclosed within its endoporus in the flywheel and make bulge loop, the bulge loop both sides lay steel ball respectively with wheel hub, axle bowl bearing fit, axle bowl endoporus is made screw thread and is connected with wheel hub, spring abutment is captiveed joint with disc spring is inner, captive joint with force transmiting disk in the disc spring outer end, force transmiting disk is connected with wheel hub.
Principle of work: flywheel is driven when rotating, and is that Case of fly-wheel drives cover rotation in the flywheel, and cover is connected with spring abutment in the flywheel, therefore drive spring abutment and rotate, disc spring is inner to be fixed with spring abutment, so disc spring rotates around spring abutment, disc spring is screwed, because disc spring outer end and force transmiting disk are fixed, so driving force transmiting disk, disc spring rotates, force transmiting disk is connected with wheel hub, therefore driving wheel hub rotates, the axle bowl is connected with wheel hub, so the commentaries on classics of wheel hub rotating band moving axis bowl, and wheel hub rotates bicycle and moves ahead.
The advantage of the invention is: because spring abutment, disc spring and force transmiting disk have been installed between flywheel and wheel hub, the inside and outside end of disc spring is captiveed joint with spring abutment, force transmiting disk respectively, and spring abutment is connected with flywheel, and force transmiting disk is connected with wheel hub.Disc spring stored energy in screwing process when riding, when Pedal flywheel rotates, the disc spring energy stored discharges at any time, give foot-operated power-assisted, especially when long distance or climbing are ridden, the energy stored that discharges disc spring reduces foot-operated power, and the sense that can lessen fatigue makes both legs that a kind of comparatively easily sensation be arranged.
Description of drawings:
Fig. 1 is a bicycle freewheel transmission device structural representation.
The specific embodiment: bicycle freewheel transmission device, chain wheel 20 is made in outer end at the Case of fly-wheel 6 of flywheel 19, bulge loop 21 is made in the inner of cover 11 in flywheel, the cylindrical of bulge loop 21 is made screw thread, the inner hole wall of cover 11 is made bulge loop 22 in flywheel, Case of fly-wheel 6 is sleeved in the flywheel on the cover 11, lay steel ball 9 and very heavy 10 earlier between the cover 11 in Case of fly-wheel 6 and the flywheel, on Case of fly-wheel 6, lay steel ball 7 again, flywheel in overlap 11 on by being threaded in cover plate 8, formed flywheel 19, spring abutment 5 the inner with disc spring 2 is fixed together, on spring abutment 5, pass through screw thread mounting plate 4, in case disc spring is inner loosening, spring abutment 5 is connected with cover 11 in the flywheel by screw thread, disc spring 2 outer ends and force transmiting disk 3 are fixing, and at this bearing's installation pressing plate 1, loosening to prevent disc spring 2 external end heads, with the flywheel of combining 19, spring abutment 5, disc spring 2 and force transmiting disk 3 are sleeved on the wheel hub, by screw thread force transmiting disk 3 is connected with wheel hub, in flywheel, laying steel ball 18 between cover 11 bulge loop 22 and the wheel hub before the suit, steel ball 17 is placed on the bulge loop 22 of cover 11 in the flywheel, axle bowl 13 is installed on the wheel hub by screw thread, lay steel ball 15 at axle bowl 13 inner chambers, axletree is inserted in wheelboss inner hole, axle shelves 14 are screwed on the axletree tighten fixing with nut 12.
Claims (2)
