Abstract

The invention discloses an electromechanical coupling buffer device of a range extender. The electromechanical coupling buffer device is used for connecting an engine flywheel and a generator spline shaft; and the device comprises a shell, a friction plate assembly and a pressure plate assembly; the engine flywheel is inserted into the shell; the friction plate assembly is arranged in a gear ringof the engine flywheel in a matched mode; a friction plate is pressed in the middle of the pressing disc assembly in a matched mode, and the edge of the pressing disc assembly is connected with the gear ring; and the generator spline shaft sequentially penetrates through the pressing plate assembly and the friction plate assembly in a matched mode, and the shell is connected with an engine. The electromechanical coupling buffer device of the range extender buffers vibration between the engine flywheel and the generator spline shaft, noise caused by impact generated by an engine and a generatorduring variable-working-condition operation is avoided, and the situation that the service life of an engine crankshaft and the service life of a crankshaft bush are affected due to the fact that theengine crankshaft and the engine crankshaft bush are subjected to large alternating loads is avoided; and meanwhile, fracture failure of bolts and splines caused by impact load is avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an electromechanical coupling buffer device for a range extender. Background technique [0002] The coupling structure between the engine and the generator in the prior art is generally a non-buffer mechanism, such as figure 1 As shown, the engine flywheel 1 and the connection plate 2 are fixedly connected by the connection plate bolts 4. At the same time, the generator shaft spline 3 is inserted in the connection plate 2. This coupling structure has no buffer mechanism, resulting in the engine running under variable conditions. There is an impact with the generator, which produces a large noise and affects the driving experience; when the operating conditions are variable, it is easy to cause the engine crankshaft and bearing bush to be subjected to large alternating loads, which will affect the service life of the crankshaft and crank bush; fasten the connecting plate. Bol...
