Gasoline-electric hybrid engine for motorcycle

Abstract

The invention discloses an oil-electric hybrid engine of a motorcycle. The oil-electric hybrid engine comprises an internal combustion engine and a drive motor, wherein a clutch is installed at one end of a crank of the internal combustion engine, the other end of the crank of the internal combustion engine is connected with an output shaft of the drive motor through a power connection device, the power connection device comprises a connection disc, the crank and the output shaft are connected with two sides of the connection disc respectively, the crank and the connection disc rotate synchronously, two one-way overrunning clutches arranged side by side are installed at the position where the output shaft matches with the connection disc, and the overrunning directions of the two one-way overrunning clutches are opposite. According to the oil-electric hybrid engine of the motorcycle, two groups of output power of the engine and the motor are combined organically, the drive motor integrates three functions of start motor, electromagnet motor and power output, technical characteristics of variable transmission and kick start of a traditional oil engine are completely preserved, and the oil-electric hybrid engine of the motorcycle has the advantages of being simple and novel in structure, high in universality and low in production cost.

Description

technical field [0001] The invention belongs to the technical field of engines and relates to a gasoline-electric hybrid engine for motorcycles. Background technique [0002] With the increasingly stringent environmental emission regulations, gasoline prices have been at a high level for a long time, and more and more large and medium-sized cities have issued restrictions on motorcycles. Small internal combustion engines (such as motorcycle engines) fueled by gasoline are facing a full impact from electric vehicles. In recent years, the total market volume of traditional fuel motorcycles has been decreasing at a rate of about 10% year by year, while the market for electric vehicles has grown rapidly year by year, far exceeding the total volume of conventional fuel motorcycles. [0003] Although electric vehicles have natural advantages in energy saving and environmental protection, they have short cruising range, inconvenient charging, short battery life, and output torque t...

AI Technical Summary

Problems solved by technology

[0004] However, the existing oil-electric hybrid technology on the market is mainly to graft the drive motor and the engine with simple functions, resulting in many missing functions. For example, because the position of the starting lever is occupied by the motor, only electric starting can be realized, and artificial kick starting cannot be realized at the same time. function, in case of an emergency, it is easy to cause the engine to fail to assist in starting, or in the electric drive mode, the self-charging battery life function cannot be retained at the same time

[0005] In addition, because the existing gasoline-electric hybrid engine adds a driving motor on the basis of the traditional fuel engine, it will inevitably lead to a complicated engine structure, which will greatly increase the cost of the engine, which is very unfavorable for consumers and manufacturers.
