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 an electric vehicle range extender. The electric vehicle range extender comprises an engine and a motor, a crankshaft of the engine is matched with a rotor of the motor in a transmission mode, and the engine comprises a left crankcase and a right crankcase matched with the right side of the left crankcase. The right crankcase is subjected to self deformation to form a containing cavity for mounting an oil pump rotor so that the containing cavity can be used as an oil pump shell; and the left crankcase is integrated with a plurality of stator mounting bosses used for mounting motor stators and a plurality of trigger mounting bosses for mounting triggers, and the left crankcase is provided with at least one limiting device for preventing a chain from falling off. Theelectric vehicle range extender integrates a pump body on the right crankcase, and the structure of the oil pump is simplified; the motor stators can be directly mounted on the left crankcase to enable the structure of the entire crankcase and motor to be compact; and meanwhile, after the left crankcase is integrated with stator mounting seats, 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 ...
