The invention relates to a connecting structure for connecting an internal combustion engine of a range extender and a generator through a planetary gear. The connecting structure comprises the planetary gear, the generator, a torque shock absorber, the internal combustion engine, an internal combustion engine output shaft and an internal combustion engine flywheel, wherein the internal combustionengine output shaft is connected with an input shaft of the generator through a coaxial planetary gear, a planetary gear sun wheel is arranged in the generator, the planetary gear sun wheel is connected with the input shaft of the generator, a planetary gear planetary wheel is arranged between the planetary gear sun wheel and a planetary gear planet carrier, a planetary gear ring shaft is coaxially arranged on the internal combustion engine output shaft, a planetary gear ring is fixedly arranged on the other end of the planetary gear ring shaft, and the planetary gear sun wheel is fixedly connected with the planetary gear ring. According to the connecting structure, the coaxial input and output is realized, and the volume weight of the range extender is reduced; compared with a parallel shaft connecting structure, the efficiency of the range extender is improved, additionally, the noise is low, and the reliability is high.
Description
technical field [0001] The invention belongs to the technical field of vehicle power equipment, and in particular relates to a connection structure in which an internal combustion engine and a generator of a range extender are connected through planetary gears. Background technique [0002] A range extender is traditionally defined as a combination of an internal combustion engine and a generator, and the range extender is an essential component of a range-extended electric vehicle. Compared with pure electric vehicles, extended-range electric vehicles equipped with range extenders have the advantages of long mileage, strong adaptability to temperature environment, and wide range of product applications; compared with traditional fuel vehicles, they have lower fuel consumption, lower exhaust emissions, and better acceleration performance , low noise and other advantages. The power of the internal combustion engine usually selected by the range extender is not large. In orde...
