Embodiment Construction

[0027] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0028] like figure 1 As shown, the range-extended hybrid system arranged coaxially in the present invention mainly includes an engine 1, a generator 2, an input assembly 3, a battery 4, a drive motor 5, an output assembly 6, an inverter 7, and the like.

[0029] The engine 1 usually provides power input for the vehicle to run, and the generator 2 is coaxially arranged with the engine 1 (in this embodiment, the motor rotor of the generator 2 is designed as a hollow shaft). The input assembly 3 mainly includes an input gear shaft 31 , an input intermediate shaft 32 , an input secondary driving gear 33 , an input secondary driven gear 34 and the like. The input gear shaft 31 is connected with the flywheel of the engine 1 through a spline, so as to realize the power input of the engine 1 . The gear of the input intermediate shaft 32 is engaged wi...

Abstract

The invention relates to a coaxially-arranged extended-range hybrid power system. The system comprises an engine, a power generator coaxially arranged with the engine, an input assembly, a battery, adriving motor and an output assembly, wherein the input assembly and the battery are connected with the power generator, the driving motor is connected with the battery and coaxially arranged with thepower generator, and the output assembly is connected with the driving motor. The input assembly is further connected with the engine and has at least five working modes including a range extending driving mode, a pure electric driving mode, a parking charging mode, an engine starting mode and an energy recovery mode. According to the coaxially-arranged extended-range hybrid power system, the power generator, the driving motor and a gear pair are integrated in a synthesis box, the integration degree is high, and matching installation is facilitated; a parallel shaft type two-stage speed reducing mechanism is used, and the structure is simple and reliable; the engine is coupled with the power generator to realize a range-extending power generation function; the engine is decoupled from thedriving system, the engine stably works at an efficient power point, higher fuel economy is obtained, and the use cost of a vehicle is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile transmission, and in particular relates to a coaxially arranged extended-range hybrid system. Background technique [0002] In recent years, with the guidance of national policies and the requirements of vehicle emission regulations, various manufacturers have launched a variety of pure electric vehicles. Due to the short mileage and high battery cost of pure electric vehicles, the market acceptance is low without government subsidies. range anxiety problem. [0003] Extended-range hybrid vehicles use electric energy as the direct power source of the vehicle. After the battery power is lower than the SOC (State of Charge) value, the engine drives the generator to generate electricity to provide electric energy to drive the vehicle. At present, there is a single type of extended-range hybrid system on the market: the engine is connected to the generator to generate electricity, and the drive ...
