Problems solved by technology

However, there are many extended-range electric vehicles at present, and the engine, generator, deceleration device, and electric motor are arranged coaxially, which makes the vehicle length too long and difficult to arrange in the engine room
And the engine is directly connected to the generator, resulting in too low generator speed and low energy density of the generator, resulting in a larger size and mass of the generator

Abstract

The invention discloses a speed reducer layout structure used for a range-extending type electric vehicle, and belongs to the technical field of electric vehicle speed reducers. The speed reducer layout structure comprises a power generation transmission mechanism, a drive transmission mechanism and a differential mechanism, wherein the power generation transmission mechanism comprises a power generation input shaft, an idle wheel shaft and a power generation output shaft; the drive transmission mechanism comprises a drive input shaft and a drive output shaft; power output by an engine is transmitted into the power generation transmission mechanism through dual mass flying wheels, and rotation speed is increased by the power generation transmission mechanism through a gear wheel of each axle, so that a power generator is driven to generate power in a high-efficiency area, and therefore, electric power is provided to a whole vehicle power battery and a drive motor; power generated by the drive motor is transmitted to the differential mechanism through secondary speed reduction of the drive transmission mechanism, and the differential mechanism is used for transmitting power to wheels to drive the whole vehicle to travel. The power transmission mechanism is more compact and simpler in structure, is convenient in assembly, and effectively overcomes the defects that an existing electric vehicle is low in endurance mileage and is high in cost due a too great power battery.

Description

technical field [0001] The invention relates to a range-extended speed reducer, which belongs to the technical field of range-extended electric vehicle speed reducers. Background technique [0002] With the increasing global greenhouse effect, the frequent occurrence of smog events in various places, and the increasing number of automobiles, automobile exhaust has become an important cause of climate change. Therefore, electric vehicles have become a very potential development of automobiles. direction. [0003] At present, due to the limitation of battery storage capacity of pure electric vehicles, the weight of the battery is heavy, so the weight of the whole vehicle is large, and it does not save electricity; there are many batteries, high specific energy, high risk, and high risk of spontaneous combustion; the battery consumption is large, and the price of the vehicle is high. , and the battery life is low, and the replacement cost is high. In order to increase the cru...
