Abstract
The utility model relates to rear shaft flywheel parts for a motor and pedal bicycle, which comprises a rear shaft roller, a rear shaft tube, a left disk chuck, a right disk chuck, a rear shaft bumper, fastening pieces, a left small flywheel, a right small flywheel and a big chainwheel. The left small flywheel and the left disk chuck are installed on the utility model by M35*1 left screw threads. The big chainwheel is tightly fixed on the left small flywheel and the left disk chuck. A machine drives the big chainwheel, the left small flywheel and the left disk chuck by a chain. Manpower drives the right small flywheel and right disk chuck compared with the prior art. The motor and pedal clutch of the utility model has the advantages of simple, convenient and energy-saving switch, small resistance, high drive efficiency. The utility model can be used on the motor and pedal bicycle.
Description
The utility model relates to bicycle, the rear flywheel parts of more clearly saying so and being used for motor-driven bicycle.
The type of drive of traditional motor-driven bicycle is the tire of machine by friction wheel friction front-wheel or trailing wheel, makes it to drive to advance.This type of drive driving efficiency is low, and wear on tyres needs often to change soon.Another kind of existing type of drive is the sprocket wheel of machine by installing additional on another chain direct drive rear axle part.When the machine stall was advanced to ride, the sprocket wheel on the rear axle part still drove this chain and corresponding component is rotated further, and resistance increases greatly, and driving efficiency reduces greatly.If ride or coasting speed when surpassing the speed of machine turns, the speed of bicycle will reduce at once.Like this, wasted fuel, again the purpose of really motor-driven, the pedal double-purpose of out of reach.
The purpose of this utility model is to overcome above-mentioned shortcoming with not enough, and a kind of driving efficiency height is provided, not only can motor-driven, pedal double-purpose, and can change clutch, mutually stack easily mutually, slide, foot-operated without hindrance the rear flywheel parts of light, energy-conservation motor-driven bicycle.
In order to achieve the above object, the rear flywheel parts of the motor-driven bicycle of the utility model are by the rear axle rod, are installed in rear axle tube, left and right sides floral disc, rear axle bowl and rear axle ball-collecting rack on the rear axle rod and rear axle bumper, fastener successively and the small flywheel that is installed on the floral disc is constituted by middle part to both sides.Small flywheel has left and right two.Right small flywheel is installed on the right floral disc, with prior art in the past.Left side small flywheel is installed on the left floral disc with left-hand thread, and left floral disc also has left-hand thread.A left side small flywheel gear ring on bolt and nut fastening a hinge wheel.Bolt and nut respectively has 4～6, just is fixed on the between cog of left small flywheel gear ring.
During use, the chain engages that machine drives is on the hinge wheel that is fixed on the left small flywheel., on right small flywheel, drive with the sprocket engagement of the original pedal of bicycle, crank, chain wheel drive with manpower.Under the driving of machine, chain drives hinge wheel, left small flywheel, left floral disc and wheel successively and advances.The ratchet of the overcoat inboard of left small flywheel drives the ratchet in the fuse outside at this moment, makes it to drive forwards trailing wheel.It is then motionless that the inboard fuse of right small flywheel is transferred its overcoat forward, the two slide relative.This moment, left small flywheel and left floral disc were that left-hand thread links, and right small flywheel and right floral disc are that right-hand thread links, and it is reasonable, reliable to use.
When machine shut down, right small flywheel drove wheel in the mode of normally riding with manpower and advances.It is then motionless that left side small flywheel fuse is transferred its overcoat forward, the ratchet of the two, ratchet slide relative.So the hinge wheel that overcoat drove is also with regard to transfixion.
The left-hand thread of left side small flywheel and left floral disc is M35 * 1.This screw thread can make left and right sides small flywheel and left and right sides floral disc that identical bottom outlet, footpath, end size are arranged, and is convenient to processing and exchange.
Motor-driven and the foot-operated automatic clutch of riding of the utility model, energy-conservation and high efficiency task come to this and finish.
The rear flywheel parts driving efficiency height of the motor-driven bicycle of the utility model, clutch easily and flexibly, light, energy-conservation, slide, all do not have when riding the machine resistance.It can be widely used in Motorized bicycle particularly on the machine pedal double-purpose mountain bike.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further to describe.
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the scheme drawing of embodiment 1 left small flywheel and fastening hinge wheel on it.
Fig. 3 is the scheme drawing of left and right sides small flywheel click.
Shown in Figure 1, embodiment 1 is made of rear axle rod 1, rear axle tube 2, left floral disc 3, right floral disc 4, rear axle bowl and rear axle ball-collecting rack and rear axle bumper 5 thereof, fastener 6, left small flywheel 7, right small flywheel 8, hinge wheel 9, chain 10.A left side small flywheel 7 and hinge wheel 9 with bolt 11, nut 12 fastening it.Left side small flywheel 7 and left floral disc 3 are connected with left-hand thread M35 * 1.
Shown in Figure 2, left small flywheel 7 and hinge wheel 9 are fastened on the between cog of left small flywheel 7 with bolt 11, nut 12.
Overcoat 13 inboards shown in Figure 3, left and right small flywheel have ratchet 14, and its fuse 15 outsides have ratchet 16, spring 17.This is a kind of representative type ratchet and pawl arrangement, successfully is applied on the bicycle freewheel already.
Present embodiment is light, flexible, and clutch is simple during motor-driven, pedal double-purpose.Its driving efficiency height, energy-conservation, can be widely used on the motor-driven bicycle.
Claims (2)
1, a kind of rear flywheel parts of motor-driven bicycle, it is by the rear axle rod, be installed in rear axle tube, left and right sides floral disc, rear axle bowl and rear axle ball-collecting rack on the rear axle rod and rear axle bumper, fastener successively and the small flywheel that is installed on the floral disc is constituted by middle part to both sides, it is characterized in that said small flywheel have about two, right small flywheel is installed on the right floral disc, left side small flywheel is installed on the left floral disc with left-hand thread, a left side floral disc also have left-hand thread, on the gear ring of left small flywheel with bolt and nut fastening a hinge wheel.
2, according to the rear flywheel parts of the described motor-driven bicycle of claim 1, the left-hand thread that it is characterized in that said left small flywheel and left floral disc is M35 * 1.
