Abstract
The utility model relates to a booster bicycle, mainly comprising a bicycle, a gasoline engine and a power transmission mechanism. A new power transmission structure is formed by adopting a simpler transmission member and arranging a transmission member around the center shaft of the bicycle; so that the utility model has the advantages of simple structure, easy manufacturing and processing, convenient maintenance and low cost.
Description
The utility model relates to morpet, particularly power drive wherein.
Morpet (hereinafter to be referred as boosted vehicle) both can be advanced in motor-driven driving, again can manpower foot-operated ride or two kinds of type of drive parallel simultaneously, therefore, seem more laborsaving, convenient than bicycle when using in many cases.Boosted vehicle mainly is confined to known structure on following several market at present: a kind of is that spark ignition engine and power drive are contained in bicycle front-wheel top, driving is advanced by the friction front tire, this structure headstock is heavy, axial dimension is big, turn to underaction, especially when the road surface is muddy, very easily skid, transmission is unreliable, is difficult to by the friction launch spark ignition engine.The boosted vehicle of another kind of structure is that spark ignition engine and driving device are placed near the cycle frame axis, and by the driving of friction rear tire, it is compared with first kind of structure except that steering flexibility and axial dimension are uninfluenced, and performance characteristics is identical.Another comparatively advanced boosted vehicle is the structure that adopts similar motor bike, spark ignition engine and driving device are installed near bicycle middle shaft or the hind axle, drive trailing wheel by the gear pair deceleration transmission in the gear case, so its complex structure, the a lot of accuracy requirement height of needs, the part that material property is good, processing and manufacturing and manufacturability require height, high material consumption, weight is heavier, cost is high, inconvenient maintenance, and bicycle generally needs special.
The purpose of this utility model provides that a kind of structure is simple especially, part is few, bicycle can be not special, convenient processing and manufacture, good manufacturability, material are economized, in light weight, cost is low and keep in repair boosted vehicle easily.
The utility model is achieved in that spark ignition engine is packed on the cycle frame thick stick beam, this particular axis installation site on bicycle middle shaft or the axle coaxial with it, and kink big belt wheel and the minor sprocket that is connected mutually; The small pulley kink and is installed the centrifugal clutch that is connected between the two on the spark ignition engine power take-off shaft; Hinge wheel and bicycle rear hub axle skin are installed the free-wheel clutch that is connected between the two; Small pulley adopts the band deceleration transmission with big belt wheel, and minor sprocket and hinge wheel adopt the chain deceleration transmission.
Second kind of embodiment of the present utility model is: spark ignition engine is packed on the cycle frame thick stick beam, this particular axis installation site on bicycle middle shaft or coaxial with it axle, kink big belt wheel and minor sprocket, and wherein big belt wheel and minor sprocket are installed the free-wheel clutch that is connected between the two; The small pulley kink and is installed the centrifugal clutch that is connected between the two on the spark ignition engine power take-off shaft; Hinge wheel is connected on the bicycle rear hub axle skin; Small pulley adopts the band deceleration transmission with big belt wheel, and minor sprocket and hinge wheel adopt the chain deceleration transmission.
The utlity model has tangible advantage, its structure is simple especially, part is few, bicycle can be not special, thereby and not damaging bicycle car load outward appearance (outward appearance is most important to boosted vehicle) on the bicycle middle shaft because big belt wheel and minor sprocket place, processing and manufacturing is easy, good manufacturability, material consumption is few, maintenance is convenient, and cost is low, and is in light weight.Another advantage of the present utility model is that existing bicycle is only done a little change and promptly can be assembled into boosted vehicle through special quality inspection is qualified.
Accompanying drawing 1 has been described an embodiment of first kind of embodiment of the utility model.
Fig. 1: the boosted vehicle of first kind of embodiment and power drive system birds-eye view.
The utility model is described in further detail below in conjunction with Fig. 1 and this embodiment.
Spark ignition engine (18) is packed on bicycle (15) the vehicle frame thick stick beam (16) through connecting panel (17), and kink and is welded to each other the big belt wheel (5) and minor sprocket (7) that (also can adopt alternate manner) is connected on the axis (14) that bicycle (15) extends slightly; Go up with hinge wheel (10) at trailing wheel hub axle skin (12) and to weld (also can the adopt alternate manner) Ratcheting one-way clutch (13) (being commonly called as flywheel) that a bicycle uses always that is being connected between the two, also can adopt override type, unilateral bearing formula or other known free-wheel clutch; Small pulley (4) kink is installed the centrifugal clutch (1) that is connected between the two on spark ignition engine power take-off shaft (3), this centrifugal clutch also can be the centrifugal clutch of other known configurations; Bearing (6) and bearing (2) install additional for alleviating friction; Adopt cone belt (8) transmission between small pulley (4) and big belt wheel (5), also can adopt synchronous cog belt or other band class transmission, but the belt wheel structure should adapt with it; Adopt chain (9) transmission between minor sprocket (7) and hinge wheel (10); In the present embodiment, band is to adopt regular tune-up center apart from what realize with the tensioning of chain, also can adopt other known tensioning mode and device; In this example: bicycle is commercially available type, also can be for improving intensity or be convenient to install or vibration damping is better etc. changes a social system or special, but and attaching sound, light and corresponding maneuver control device; The spark ignition engine throttle is contained in right handrail in the usual way last (omitting among the figure), and petrol engine oil tank and spark ignition engine are one, also can be placed on other position of vehicle frame.
The operation logic of this boosted vehicle is as follows: pulling hand start device (19) (or electricity starting), spark ignition engine (18) starting, when its little throttle low-speed running, centrifugal clutch (1) on its power take-off shaft (3) is because of passing speed less than engaging rotating speed, so do not engage, not transfer of small pulley (4), the zero load idle running of spark ignition engine (18), when open the throttle wide to spark ignition engine power take-off shaft (3) rotating speed during greater than the engaging rotating speed of centrifugal clutch (1), centrifugal clutch (1) is in engagement state, drive small pulley (4) rotation on it, through cone belt (8) deceleration transmission big belt wheel (5) and the minor sprocket on it (7) are rotated around axis (14), again and then by chain (9) deceleration transmission hinge wheel (10) is rotated, because being in engagement at this moment, single direction ratchet power-transfer clutch (13) turns to, so hub axle skin (12) is driven transfer, boosted vehicle is advanced.When riding by manpower is foot-operated, bicycle freewheel (11) is in engagement and turns to, the sliding hub axle skin of bicycle (12) rotates, but since be in free-wheel clutch (13) this moment on the hinge wheel (10) surmount separate walk around to, hinge wheel (10) can not be driven transfer, travels so bicycle is driven by manpower.Obviously when motor-driven and manpower while during parallel drive, can be independent of each other, propulsive effort is made a concerted effort for it.
Accompanying drawing 2 has been described an embodiment of second kind of embodiment of the utility model.
Fig. 2: the boosted vehicle of second kind of embodiment and power drive system birds-eye view.
Because of the example structure and the principle of this scheme and first scheme are close, for no longer narration for simplicity, only provide Fig. 2, its each part sequence number and title and the just the same wherein part of scheme one embodiment (13) they are free-wheel clutch, do not analyse and observe among the figure.
