Flywheel rotor split type quick connection structure for range extender

Abstract

The application relates to a flywheel rotor split quick-connection structure for a range extender, mainly comprising an engine flywheel body, a transition flange, fixing bolts, a spline shaft and a positioning snap spring, wherein the transition flange cooperates with the spline shaft by adopting a special structure design, the outer side of the transition flange is connected with the flywheel body through uniformly distributed bolts, the axial inner side of the transition flange is connected with a motor rotor through the spline shaft, the bolt connection and spline cooperation are combined, transition transmission connection of the engine and the motor rotor is realized, the connection structure can effectively solve the problems of kinetic energy loss and great coaxiality calibration difficulty in the matching process of the engine crankshaft and the motor rotor in the traditional range extension system scheme, split connection of the engine and the motor is realized, assembly efficiency and maintainability are improved, and the range extender matching design has high applicability to the medium and small power sections.
