AI Technical Summary

Technical Problem

The existing range extender structure cannot achieve low speed input and high speed output without increasing length and size, resulting in high cost, large weight and large size problems.

Method used

The planetary gear assembly is used to be arranged inside the generator housing, and is fixed to the first end cover through the inner ring of the planetary gear assembly. The planetary carrier is driven to the engine output shaft, and the sun gear is driven to the planetary carrier to achieve the height of the rotor shaft. Speed ​​output and reduce space occupancy of planetary gear assembly.

Benefits of technology

The low cost and high efficiency of the range extender is achieved, with the advantages of short size and low weight, reducing the space size and cost of the planetary gear assembly and improving the efficiency of the generator.

Abstract

The utility model particularly relates to a generator, a range extender and a vehicle, the generator is used for the range extender of an electric vehicle, and the generator specifically comprises a casing and a planetary gear assembly. A rotor shaft is rotatably arranged in the casing, and the casing is provided with a first end cover. The planetary gear assembly is arranged on the first end cover and located in the machine shell, the planetary gear assembly comprises an inner gear ring, a planet carrier and a sun gear, the inner gear ring is fixed to the first end cover, the planet carrier is used for being in transmission connection with an output shaft of the engine, and the sun gear is arranged at the first end of the rotor shaft and is in transmission connection with the planet carrier. According to the generator, the planetary gear assembly is arranged in the shell of the generator, and the planet carrier is in transmission connection with the output shaft of the engine and the sun gear of the rotor shaft, so that low-rotating-speed input and high-rotating-speed power generation of the range extender can be realized, the space occupied by the planetary gear assembly can be reduced, the range extender has the advantages of being short in size, small in size and high in reliability. The cost is low; and the weight is light.
