Abstract
The utility model relates to an overriding clutch of a booster bicycle, which is composed of a small flywheel, a fixing sleeve installed in an inner screw hole of the small flywheel, a small chain wheel and a cushion ring installed on the fixing sleeve, a bearing installed in an inner hole of the fixing sleeve, and an elastic damping ring for a hole. The specification of the connecting screw of the fixing sleeve, the small flywheel and the small chain wheel is M35 multiplied 1. The utility model has the advantages of high transmission efficiency, manoeuvrability, small resistance under the condition of single manoeuvrability or pedaling, flexible clutch and reliable brake. Pedals of the utility model can be superimposed, and the utility model can be used on booster bicycles with foot brakes.
Description
The utility model relates to motor-driven bicycle (being moped), the moped free wheel device of the drive part that is used for moped of more clearly saying so.
The current moped kind of drive, the one, the output shaft of internal-combustion engine drives moped by friction wheel friction front tyre or rear tyre and advances.This driving mode transmission efficiency is low, and friction slip, tire abrasion are fast when sleet.The 2nd, shaft drive.By the output shaft of internal-combustion engine, the transaxle by moped drives trailing wheel and advances.This driving mode, the component processing complexity, the cost height, general part is few.The 3rd, chain-driven.The output shaft minor sprocket of internal-combustion engine advances by chain drive trailing wheel hinge wheel.When the machine stall is foot-operated when riding, the sprocket wheel of wheel drives chain to be changeed as usual and helps, and resistance increases greatly, and transmission efficiency reduces greatly.If ride or sliding speed when surpassing the rotating speed that internal-combustion engine rotates, the speed of moped will reduce at once.So both waste fuel, do not reached purpose really motor-driven, pedal double-purpose again.
The purpose of this utility model, be to overcome above-mentioned shortcoming with not enough, a kind of transmission efficiency height is provided, not only can motor-driven, pedal double-purpose, and can be easily according to the speed per hour requirement just of moped, the size of changing conversioning wheel mutually reduces or increases the speed per hour of moped; Change clutch simply, can realize that power superposes mutually; Slide, ride without hindrance; Climbing when steep not only can be motor-driven but also can add foot-operatedly, has reached the moped free wheel device of the effect of real power-assisted.
In order to achieve the above object, the utility model moped free wheel device, by interior round belt have the middle part of internal thread and cylindrical have its left side of a thousand pieces of gold spring have externally threaded fuse, be installed in the cover right side the flat shelves that have alley, be installed in screw thread in the silk shelves that have alley, the interior circle middle part in cover left side have its both sides of a thousand pieces of gold and have about two alleys be sleeved on periphery on the fuse by the overcoat of sprocket wheel, be installed in about steel ball in two alleys constituted.This structure is the structure of the small flywheel parts stipulated among the standard GB 3564-83.In other words, small flywheel is the clutch of a kind of folk prescription to clutch.During the forward running, overcoat sprocket wheel and fuse close, and driving is advanced; During antiport, overcoat sprocket wheel and fuse are from the idle running of, overcoat.
Also fixing the fixed cover that has endoporus and convex shoulder in the small flywheel inner bolt hole of the present utility model, minor sprocket and packing ring are being installed between fixed cover convex shoulder and the small flywheel with screw thread.Two bearings are installed in the endoporus of fixed cover, and a side of bearing is installed with the circlip for hole that is stuck in the fixed cover endoporus annular groove.The connecting thread of fixed cover and small flywheel, minor sprocket is M35 * 1.This screw thread had both kept the general interchangeability of small flywheel, had simplified the technology capability and the assembly process process of overcoat sprocket wheel again, had improved join strength.Minor sprocket on the general backpedalling brake of minor sprocket, general interchangeability is good, separately manufacturing.During use: earlier the utility model is installed on the autocratic fixing frame of vehicle frame, minor sprocket is interior, and small flywheel outside.Add that according to the chain gauge size suitable packing ring is with jail on the clutch.The internal-combustion engine drives chain engages is on the minor sprocket of this clutch.Minor sprocket and small flywheel tighten together.The special-purpose hinge wheel that the small flywheel of this clutch just drives chain drive moped trailing wheel advances.The chain engages of the original pedal of bicycle, crank, chain wheel drive is on the minor sprocket of back backpedalling brake.When manpower is ridden, drive the back backpedalling brake and advance.It is sensitive reliable that backpedalling brake possesses brake.Mud sleet road is durable in use, the mountain area, town and country is suitable characteristics.So it is best structure that moped adopts backpedalling brake to mix the new property free wheel device of this practicality.Under the driving of internal-combustion engine, chain drives the minor sprocket of this free wheel device successively, and the hinge wheel that specially is added on the backpedalling brake that is transmitted small flywheel drive chain drive trailing wheel by minor sprocket rotates.At this moment, the minor sprocket of backpedalling brake is then motionless, is provided with resistance.Since effect of the present utility model, the two slide relative.Hinge wheel that specially adds on the backpedalling brake and backpedalling brake wheel skin link one, and be strong, uses rationally, and running is reliable.
When engine stops, drive pedal, crank, axis, axis sprocket wheel, chain, backpedalling brake minor sprocket in the mode of normally riding successively with manpower and drive trailing wheel and advance.At this moment the hinge wheel of backpedalling brake drives small flywheel slip of the present utility model, and the minor sprocket of clutch is then motionless.Internal-combustion engine does not produce resistance.
Minor sprocket of the present utility model is M35 * 1 right-hand thread, and small flywheel is M35 * 1 right-hand thread.Fixed cover is the screw thread of external diameter M35 * 1.Endoporus is installed two on 100 bearings.Circlip for hole is installed in the bearing outside.Then use the hexagon socket head cap screw of M10 * 60 to be fixed on the fixing frame of autocracy of moped.
Task of the present utility model comes to this and finishes.
The utility model transmission is efficient, fuel-economizing, ride light laborsavingly, without hindrance when sliding, and the clutch freedom is light.Can add anti-rattler easily on the trailing wheel.Simultaneously, the backpedalling brake brake is reliable.It can be widely used on the backpedalling brake moped.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further to describe.
Fig. 1 is the new embodiment's 1 of this practicality a structural representation.
Schematic representation when Fig. 2 is embodiment's 1 use.The utility model embodiment 1 shown in Figure 1 is made of with fixed cover 4, bearing 5, circlip for hole 6 small flywheel 1, packing ring 2, minor sprocket 3, connection, uses hexagon socket head cap screw, packing ring, spring washer, the nut of M10 * 60 to be fixed on the fixing frame 7 then again.
Shown in Figure 2, the utility model embodiment 1 is installed on the fixing frame 7 of moped vehicle frame.The output chain 9 of internal-combustion engine 8 is engaged on embodiment 1 the minor sprocket 3.The hinge wheel 11 of backpedalling brake is given in chain 10 transmissions of engagement on embodiment 1 the small flywheel 1, is engaged with.Tensioning chain 12 is with chain 10 tensionings.Axis sprocket wheel 13 chain drive-belts 14 drive the minor sprocket 15 of backpedalling brake again, and this is the original driving mechanism of pedal brake bike.
Embodiment's 1 transmission efficiency height, motor-driven, pedal double-purpose can superpose.There is not the internal-combustion engine resistance when foot-operated.Clutch is flexible, makes reliable.Can be widely used on the backpedalling brake moped.
