Detailed Description
In order to make the technical solutions and advantages of the present application clearer, the following will describe the embodiments of the present application in further detail with reference to the accompanying drawings.
With the increasing use of automobiles, the pollution of automobile exhaust becomes a main source of urban air pollution. Influenced by national policies, more and more new energy automobiles walk into the visual field of consumers. The hybrid electric vehicle is gradually favored by the market with excellent energy conservation and emission reduction and excellent user experience.
Various automobile enterprises in China are actively researching and developing hybrid power systems, particularly the integrated development of special transmissions for hybrid power. However, most hybrid power systems on the market are developed on the basis of traditional automatic gearboxes, and the motors are simply integrated AT the front ends or the rear ends of gearboxes such as AT, AMT, CVT or DCT to form the hybrid gearbox. This type of hybrid transmission suffers from significant drawbacks: the gearbox is too large in size and too complex in structure, so that the manufacturing cost is high, and the control difficulty is high.
In order to solve the technical problem, the embodiment of the application provides a gearbox which is simple and compact in structure and easy to control.
As shown in fig. 1, the transmission 1 provided in the embodiment of the present application includes a housing, a first motor 11, a selection control component 12, a first power transmission shaft 13, a second power transmission shaft 14, a power generation device 15, and a power output component 16, where the first motor 11, the selection control component 12, the first power transmission shaft 13, the second power transmission shaft 14, the power generation device 15, and the power output component 16 are all located inside the housing.
Wherein the engine 2 of the vehicle is connected to at most two of the first and second force transmission shafts 13, 14 by means of the selection control assembly 12; the first transmission shaft 13 is connected with the first motor 11; the second force transmission shaft 14 is connected with a power generation device 15, and the power generation device 15 is connected with the first motor 11; the power take-off assembly 16 is connected to the first power shaft 13.
In the transmission 1 provided in the embodiment of the present application, the first motor 11 is integrated inside the transmission 1, and cooperates with the engine 2 of the vehicle to provide the vehicle with two power sources, and the two power sources may respectively and independently operate to provide power for the vehicle, or may operate together to provide power for the vehicle.
The selection control module 12 is a structure for controlling whether the power of the engine 2 is output outward, and determining the power output direction at the time of the output outward. The phrase "the engine 2 of the vehicle is connected to at most two of the first power transmission shaft 13 and the second power transmission shaft 14 through the selection control assembly 12" in the embodiment of the present application means that the engine 2 may be connected to neither the first power transmission shaft 13 nor the second power transmission shaft 14 through the selection control assembly 12, may be connected to either one of the first power transmission shaft 13 and the second power transmission shaft 14 through the selection control assembly 12, and may be connected to both the first power transmission shaft 13 and the second power transmission shaft 14 through the selection control assembly 12.
When the engine 2 is not connected with the first power transmission shaft 13 and the second power transmission shaft 14 through the selection control assembly 12, the engine 2 cannot output power outwards. At this time, the first motor 11 can be used as the only power source, that is, only the power output by the first motor 11 is transmitted to the power output shaft, so as to drive the vehicle to run.
When the engine 2 is connected with the first power transmission shaft 13 through the selection control assembly 12, the power output by the engine 2 can be transmitted to the power output shaft through the first power transmission shaft 13, so that the power of the engine 2 can be used for driving the vehicle to run.
When the engine 2 is connected with the second force transmission shaft 14 through the selection control assembly 12, the power output by the engine 2 can be transmitted to the power generation device 15 through the second force transmission shaft 14, and the power generation device 15 is driven to convert the mechanical energy into the electric energy, so that the power generation device 15 can store the converted electric energy or supply power to the first motor 11.
When the engine 2 is connected with both the first power transmission shaft 13 and the second power transmission shaft 14 through the selection control assembly 12, the engine 2 can output power to a power output shaft for driving the vehicle to run on the one hand, and can also output power to the power generation device 15 for driving the power generation device 15 to generate power for storing energy or supplying power on the other hand.
