Description

Integrated shell and rear-end output range extender structure

Technical Field

The utility model belongs to the technical field of engines, and particularly relates to an integrated shell and rear-end output range extender structure.

Background

Energy conservation and environmental protection are the permanent subjects in the field of automobiles, and it is well known that a pure electric automobile cannot meet long-distance travel due to the influence of factors such as low specific energy and high price of the conventional power battery, and people have mileage anxiety on the pure electric automobile. The range extender can effectively solve the problem of mileage anxiety of the pure electric vehicle and becomes the development trend of new energy vehicles. The range extender is generally composed of an engine + a generator. The crankshaft of the engine is connected with the motor through an electromagnetic clutch, namely the motor is directly connected to the engine through the torsion reduction, although the torsion reduction is integrated into the rotor assembly, the length of the rotor assembly is still superior, and the cost of the torsion reduction is increased; secondly, the stability and reliability of the rotor assembly are not sufficient.

For example, the chinese utility model patent with publication number CN208664976U discloses a range extender for an electric vehicle with integrated motor, which is used as a technology of a range extender of the previous generation, directly cancels a flywheel, realizes length shortening by reducing parts, but also brings disadvantages; it can be seen that the range extender can only be used for generating electricity and can not directly output mechanical driving force.
