Abstract

The utility model relates to a gasoline engine booster bicycle transmission device, which belongs to the transmission device of a bicycle, mainly comprising a front ratchet wheel, a rear ratchet wheel, a v-belt pulley, a v-belt, a jaw clutch, a clutch control handle, an engine, etc. The utility model is characterized in that the front ratchet wheel and the v-belt pulley are arranged on the centre shaft of a bicycle; the front ratchet wheel is arranged in a reversed way to be symmetrical with the rear ratchet wheel; the jaw clutch is arranged on the output shaft of the engine; the v-belt is respectively connected to the v-belt pulley and the jaw clutch. The utility model has the advantage of reasonable design and can be driven not only by the man-power foot pedal but also by the engine force.

Description

Gasoline engine aid bicycle transmission device

The utility model belongs to bicycle drive, and what relate generally to is a kind of spark ignition engine morpet actuating device, and it both can drive by manpower is foot-operated, again can be by the bicycle of mechanical powered drive.

At present, the power-assisted mini-motorcycle that sell on the market or people use, basically all be on the basis of existing bicycle, set up an actuating device in addition, mainly lean on the pressing friction of rear tyre and output wheel to drive engine ignition work when driving, so often because of road surface rain, snow owing to it, the surface of tyre wearing and tearing, reasons such as underinflation of tire skidding occurs when driving, cause the driving engine cisco unity malfunction.In addition, because this type of drive has also been aggravated Tyte Wear, increased the service expenditure of bicycle.

The purpose of this utility model promptly produces thus, a kind of later-model driving device is provided, it changes friction-driven when driving be that belt-driving drives, thereby overcome the drawback of friction-driven, improved the service life of tire, and belt-driving drives the restriction that engine ignition work is not subjected to any environment and condition.

For achieving the above object, the utility model is achieved through the following technical solutions: its mainly by preceding ratchet, pulley conical disk, cone belt, chain, back ratchet, denture clutch, shift fork, draw wheel, clutch operating handle, driving engine to constitute.Pulley conical disk and preceding ratchet are installed on the bicycle middle shaft, preceding ratchet upside-down mounting, with back ratchet ratchet symmetry, its outer shroud and pulley conical disk are fixed, denture clutch is fixed on the engine output shaft, it is made up of fixed part and moving part, and in the output shaft termination, cone belt connects pulley conical disk and power-transfer clutch fixed part to fixed part by its interior bearing fixing that is provided with.Its moving part is provided with shift fork, is fixed with on the shift fork to draw wheel, draws wheel to be connected by cable wire with the clutch control handle.

The utility model is rational in infrastructure, changes friction and drives to belt pulley drives, thereby make driving engine not be subjected to the restriction of any environment and condition when igniting, and improved the service life of tire.

The utility model has following accompanying drawing:

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is the structural representation at the utility model axis position.

Accompanying drawing 3 is the utility model clutch configuration scheme drawing.

Accompanying drawing 4 is the utility model power-transfer clutch A-A generalized section.

Accompanying drawing 5 is the utility model clutch control handle scheme drawing.

In conjunction with the accompanying drawings, the utility model is described in further detail:

As shown in Figure 1: the utility model mainly by preceding ratchet 2, pulley conical disk 4, cone belt 5, chain 9, back ratchet 10, denture clutch 7, shift fork 19, draw wheel 26, clutch control handle 22, driving engine 3 etc. to form, cone belt 4 all is arranged on the bicycle middle shaft with preceding ratchet 2, pulley conical disk 4 is captiveed joint with the outer shroud of preceding ratchet 2 by bolt 16, preceding ratchet 2 upside-down mountings, symmetrical with back ratchet 10, its objective is when engine drive is worked, when its outer shroud rotating speed surpasses interior ring, interior ring stops operating, and drives transmission by driving engine.Be with chain 9 on the outer shroud of outer shroud and back ratchet 10, denture clutch 7 is arranged on the output shaft 6 of driving engine 3, it is made up of moving part and fixed part, fixed part is fixed on the termination of output shaft 6 by the interior bearing of establishing 30 usefulness bolts 31, it links to each other with vee-pulley 4 by cone belt 5, moving part is meshed with fixed part, output shaft 6 is provided with feather key 27, shift fork 19 snaps in the groove of moving part, draw wheel 26 to captive joint, draw and take turns 26 and be connected on the handgrip that bar handle is arranged on bicycle by cable wire 21 with clutch control handle 22 with shift fork 19.Working process of the present utility model is as follows: prestart, open electricity and turn round 23, energized, cable wire on the clutch control handle 22 21 is loosened, draw wheel 26 under the effect of spring 24, causing shift fork 19 to drive the power-transfer clutch moving part is meshed with the power-transfer clutch fixed part, make this system enter mode of operation, then by manpower pedal crank 15, drive preceding ratchet 2 and pulley conical disk 4 work on the axis 1, driving engine 3 is by the drive down-firing work of output shaft 6 at cone belt 5, and its power returns denture clutch again by output shaft 6, drive whole drive system work through cone belt 5, thereby reach the purpose of engine drive bicycle running.When not needing the driving engine transferring power, power cutoff 23, driving engine 3 extinguishes, foot-operated ending slightly with 21 tensions of the cable wire on the clutch control handle 22, under its effect, the moving part of power-transfer clutch is separated with its fixed part, the manpower pedal that system promptly enters Regular Bicycle drives.

Claims

1, a kind of spark ignition engine morpet driving device that constitutes by pulley conical disk, cone belt, chain, back ratchet, driving engine, it is characterized in that: bicycle middle shaft is provided with preceding ratchet, preceding ratchet upside-down mounting, symmetrical with the ratchet that is arranged on the back ratchet on the trailing wheel, pulley conical disk is captiveed joint with the outer shroud of preceding ratchet; Denture clutch is arranged on the engine output shaft, fixes by the bearing and the output shaft that are provided with in it, draws wheel to be arranged on the shift fork of denture clutch, is connected with the clutch control handle by cable wire.
