Abstract

The utility model relates to a portable bicycle with an auxiliary engine, comprising a bicycle, an engine, a clutch, a carburetor, an igniter, a silencer and an oil tank, wherein, a suspension element and a thread sleeve are fixed under a bicycle frame between a front and a back wheels of the bicycle l the engine is fixed on the suspension element by screws. The silencer is fixed under the engine. A driving shaft of the engine can be directly connected with pedals; a big chain wheel connected with a small chain wheel with a ratchet wheel through a chain is arranged on the driving shaft; the small chain wheel is arranged on the back wheel. The utility model has compact structure, simplification, small size, light weight, low center of gravity, reliable and steady ride, flexibility, reliability and convenient operation.

Description

Light morpet

The utility model relates to a kind of bicycle, especially a kind of light morpet that has auxiliary motor equipment.

The morpet of the various models of Chu Xianing in the market, the overwhelming majority is that to develop the boosted vehicle of coming on the structure of motor bike be exactly motorization in other words.Its weak point is: volume is big and heavy, complex structure, fault rate height, cost height, particularly noise silencer is not only long but also big, be exposed at by the vehicle frame outward, and when travelling, noise silencer temperature height, when the operator gets on or off the bus slightly a carelessness will be scalded legs and feet, very dangerous; And present boosted vehicle generally is the transmission respectively of a spool chain, even the shaft drive structure is also very complicated, cost increases, and noise is big, and it is also not quite convenient that driving system is switched.

The purpose of this utility model is to provide a kind of compact conformation, and volume is small and light, and manpower, powershift be morpet easily.

The utility model is achieved in that a kind of light morpet, it comprises bicycle, driving engine, power-transfer clutch, carburettor, firing unit, noise silencer, fuel tank, it is characterized in that: the vehicle frame below between the bicycle wheels is fixed with and hangs and swivel nut, with screw driving engine is fixed in the suspension, its compact conformation, volume are little, and center of gravity is low; Noise silencer is fixed on the driving engine below, hides very ingeniously, and not outer being exposed at by the vehicle frame guaranteed that the operator can not produce the scald phenomenon, guarantees personal safety; The imput shaft of driving engine directly links to each other with stretcher, and the minor sprocket bonded assembly hinge wheel of a band ratchet on chain and rear wheel is installed also on the imput shaft, drive the minor sprocket of rear wheel by hinge wheel, chain, drive rear wheels is advanced car, this manpower drives, the shared one group of sprocket wheel chain of power driven, only need the clutch switch on the handlebar is controlled, just can carry out manpower, powershift easily.

Described driving engine is light-duty spark ignition engine.

Both sides, cycle frame below are equipped with chain box, in order to protection driving engine and chain.

This light morpet compact conformation, simplification, volume is little, and is in light weight, center of gravity is low, riding safety steadily, flexibility and reliability, easy to operate.

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1: the structural representation of the utility model embodiment.

A kind of light morpet, it comprises bicycle, driving engine 3, power-transfer clutch 9, carburettor 4, firing unit 19, noise silencer 17, fuel tank 5, wherein vehicle frame 2 belows between the bicycle front and back wheel 1,10 are fixed with suspension 8 and swivel nut 7, with screw 6 driving engine 3 are fixed on and hang on 8; Noise silencer 17 is fixed on driving engine 3 belows; The imput shaft 18 of driving engine 3 directly links to each other with stretcher 14, and the minor sprocket 12 bonded assembly hinge wheels 16 of a band ratchet 13 on chain 15 and rear wheel 10 also are installed on the imput shaft 18.

This driving engine is light-duty spark ignition engine.

Both sides, cycle frame 2 below are equipped with chain box 11.
