Problems solved by technology

[0002] Most of the existing range extenders use the cycloidal rotor pump as the oil pump, and the usual arrangement is that the oil pump is fixedly connected in the engine as an independent unit. This structure requires additional intermediate connectors for fixed connection of the oil pump. The existence of parts leads to the accumulation of installation errors, and increases the number of parts, increases the space required to install the oil pump, increases the difficulty of assembling the oil pump, and increases the requirements for the space layout of parts, especially for a certain The layout of some light weight, small space and low development cost engines is particularly difficult

Abstract

The invention discloses a range extender for an electric vehicle, which includes an engine and a motor. The crankshaft of the engine is in transmission cooperation with the rotor of the motor. The engine includes a left crankcase and a right crankcase matched with the right side of the left crankcase. The right crankcase itself is deformed to form a housing chamber, which is used to install the oil pump rotor, so that the housing chamber serves as the oil pump casing; on the left crankcase, there are several integrated motor stators around the crankshaft bearing installation hole. The stator mounting boss and the trigger mounting boss used to install the trigger, the left crankcase has at least one limit device to prevent the chain from falling off; the invention integrates the pump body on the right crankcase, which simplifies the operation of the oil pump. The structure; the motor stator can be directly installed on the left crankcase to make the structure of the whole crankcase and the motor compact. At the same time, after the left crankcase is integrated with the stator mounting seat, the concentricity of the stator and the rotor is higher, and the output performance of the motor is more stable.

Description

technical field [0001] The invention belongs to the technical field of range extenders, and relates to a range extender for electric vehicles. Background technique [0002] Most of the existing range extenders use the cycloidal rotor pump as the oil pump, and the usual arrangement is that the oil pump is fixedly connected in the engine as an independent unit. This structure requires additional intermediate connectors for fixed connection of the oil pump. The existence of parts leads to the accumulation of installation errors, and increases the number of parts, increases the space required to install the oil pump, increases the difficulty of assembling the oil pump, and increases the requirements for the space layout of parts, especially for a certain The layout of some light weight, small space and low development cost engines is particularly difficult. [0003] Therefore, there is a need for a range extender for electric vehicles, which has a compact structure, is easy to ...
