Horizontally opposed range extender

Abstract

The invention provides a horizontally opposed range extender, which belongs to the fields of power generating equipment and new energy automobiles. The horizontally opposed range extender comprises an internal combustion engine and a generator, wherein the internal combustion engine comprises a left cylinder body and a right cylinder body, the left cylinder body and the right cylinder body are interconnected to form a crankcase, a rotatable crankshaft is arranged in the crankcase, two crank throws are arranged on the crankshaft, connecting rods are respectively connected to the two crank throws, pistons are respectively connected to the two connecting rods, the two pistons are respectively in sliding connection to the insides of a left piston cylinder and a right piston cylinder, the left piston cylinder and the right piston cylinder are oppositely arranged on both sides of the crankshaft, the axial leads of the left piston cylinder and the right piston cylinder are mutually parallel, and a rotor of the generator is fixedly connected to the output end of the crankshaft. According to the horizontally opposed range extender, the size of the cylinder bodies can be effectively reduced, the length of the crankshaft can be shortened, so that the processing difficulty and intensity are reduced, and additionally, the running balance of the crankshaft can be increased, so that the noise and vibration of the internal combustion engine can be effectively reduced during running, and the NVH (Noise Vibration and Harshness) problem of the range extender is effectively solved.

Description

technical field [0001] The invention relates to the field of power generation equipment and the field of new energy vehicles, in particular to a horizontally opposed range extender. Background technique [0002] A range extender usually consists of two parts: the internal combustion engine and the range extender. Among them, the internal combustion engine is a kind of power machinery, which is a heat engine that directly converts the heat energy released by the fuel into the power by burning the fuel inside the machine, and the generator is a mechanical device that converts the power output by the internal combustion engine into electrical energy. [0003] However, most of the existing range extenders have the problems of large volume, long crankshaft, troublesome processing, high noise, severe vibration and poor balance during operation. Contents of the invention [0004] The object of the present invention is to provide a horizontally opposed range extender to improve t...
