Abstract
The utility model discloses a double-chain high-speed bicycle. The utility model is characterized in that the circular motion of pedals is changed into the motion of treading up and down tread; the pedals drive multiple stage connecting rods; a final stage connecting rod is connected with a chain I to rotate a small chain wheel, and a large chain wheel which is coaxial with the small chain wheel drives wheels to rotate through a chain II so that the bicycle can run. The utility model has the advantages that the inertia of the bicycle is fully utilized; the speed is enhanced, and therefore, the utility model is more easiness and labour saving when ridden.
Description
The utility model is the improvement technology to bicycle, is specifically related to a kind of double-stranded high-speed bicycle.
Ordinary bicycle all is single chain gear, and stretcher moves in a circle, and the force of inertia of car itself is failed to make full use of, and the mode of motion of stretcher is the physiological characteristic of suitable human body.
The purpose of this utility model provides a kind of double-stranded high-speed bicycle, and it can make full use of the motional inertia of car body itself, can improve the speed of bicycle, and it is lighter, more laborsaving that the people is pedaled.
The technical solution adopted in the utility model is: double-stranded high-speed bicycle comprises vehicle frame, front axle, rear axle, stretcher, support, crossbeam, flywheel, rim, tire, spoke, saddle and handlebar, stretcher of the present utility model is a pressure lever type, the centre of bar is hinged on the vehicle frame by drift bolt, rear end articulated linkage I, the other end of connecting rod I is hinged on the centre of connecting rod II, the connecting rod II is a curved bar, its lower end is hinged on the vehicle frame rear portion by drift bolt, the upper end is hinged with the connecting rod IV, the other end of connecting rod IV and connecting rod III lower hinge, the connecting rod III also is a curved bar, middle bending place is hinged on the journal stirrup at saddle pole middle part, and the two ends of connecting rod III are connected with the chain II is closed, and the chain II is on minor sprocket, minor sprocket is coaxial with hinge wheel, on the hinge wheel around the chain I also on the flywheel of trailing wheel; On the vehicle frame below the stretcher stop pin is arranged.When riding, both feet are alternately stepped on left and right sides pedal, when pedal is depressed, drivening rod I, II, III, IV, and by the middle spot wobble of connecting rod III around its bending, make the chain II drive minor sprocket and rotate, thereby make coaxial hinge wheel drive wheel, forward walking by the chain I.Minor sprocket is a flywheel structure, and forward and reverse motion of chain II all makes minor sprocket and hinge wheel single direction rotate.
The utility model makes stretcher to being the secondary transmission between the wheel owing to increased a chain, has both cushioned the dead point of resistance arm, and the inertia of car itself is fully used, and energy raising speed is ridden more easily laborsaving.Simultaneously, the circular movement that becomes stretcher more meets people's physilogical characteristics into stepping up and down, makes the people feel comfortable.
Further specify structure of the present utility model below in conjunction with drawings and embodiments.
Accompanying drawing is a structural representation of the present utility model.
Double-stranded bar high-speed bicycle comprises vehicle frame 2, pedal 3, support 4, front axle 1, rear axle 11, crossbeam 9, flywheel 10, rim 12, tire 13, spoke 14, saddle 19 and handlebar 25, its power pack section is to drive the level Four connecting rod by stretcher 3, and the swing by the final stage connecting rod drives chain, rotates through secondary chain belt motor-car wheel.Stretcher is the depression bar form, be hinged on the vehicle frame 2 by drift bolt in the middle of it, the lower end of depression bar and connecting rod I 6 are hinged, connecting rod I 6, II 7, IV 23, III 21 is hinged successively, the connecting rod I, IV is a straight-bar, II, III is a curved bar, respectively with vehicle frame 2 and saddle vertical rod on journal stirrup 22 hinged, on the stretcher, under step, by the transmission of level Four connecting rod, finally change the swing of connecting rod III hinge-point in the middle of it into, connecting rod III two ends closed bonded assembly chain II 20 drives minor sprocket 17 and rotates, and minor sprocket 17 is a flywheel structure, and its unidirectional rotation makes the hinge wheel coaxial with it 16 rotate again, and, garage is walked through chain I 15 drive flywheels 10 and trailing wheel rotation.Strut bar I 8 and strut bar II 18 are arranged between vehicle seat and the vehicle frame, and large and small sprocket wheel promptly is fixed between two strut bars.Be connected with spring 5 between stretcher depression bar and the connecting rod II, the effect of spring 5 is that each connecting rod is resetted.Stop pin 24 is arranged on the vehicle frame below the stretcher depression bar, be used to limit the motion amplitude of stretcher.
