It can be seen that in the embodiment, the first differential 3 is additionally arranged on the front driving shaft 7, so that the connection with the engine 1 can be disconnected at the low speed of the vehicle, the engine 1 can work in the optimal interval, the connection with the engine 1 is closed at the high speed, the engine 1 can directly drive the vehicle, the energy conversion link is reduced, and the oil consumption of the whole vehicle is reduced.
Referring to fig. 2 and 3, the first differential 3 in the above embodiment is an electromagnetic clutch differential. The first differential 3 comprises a differential body and an electromagnetic clutch, the output end of the engine 1 is connected with the power input end 31 of the differential body, and a clutch body 35 of the electromagnetic clutch is detachably connected with a planet wheel 34 of the differential body; when the clutch body 35 is in engagement with the planet wheels 34, the output power of the engine 1 can be transmitted to the front drive shaft 7 via the power input 31. When the clutch body 35 and the planetary gear 34 are in a non-engagement state, the front drive shaft 7 does not obtain the output power of the engine 1, and at this time, the front drive shaft 7 cannot be driven by the engine 1.
Considering that the power consumption driven by the motor is large when the automobile runs at a high speed, if the generator 2 is directly driven by the generator 2 to charge the power battery pack 4 and then the power battery pack 4 outputs the stored electric energy to the driving motor 5, the electric energy loss can be further increased by the electric energy conversion mode. In the present embodiment, the first differential 3 is provided on the front drive shaft 7, so that the engine 1 can be used to directly drive the front drive shaft 7 through the first differential 3, and thus the vehicle can be driven to run. Because the electric energy conversion link of the power battery pack 4 is reduced, the energy utilization rate is improved, and the energy loss is reduced.
In addition, the first differential 3 further includes a housing 32, a pressure plate 36 and a diaphragm spring 33, an opening for moving the clutch body 35 is provided at a position where the housing 32 is opposite to the pressure plate 36, the diaphragm spring 33 is provided between a side wall of the housing 32 and the pressure plate 36, and one end of the clutch body 35 is fixed to the pressure plate 36; when the electromagnetic clutch is under the action of electromagnetic pressure, the gear end of the clutch body 35 and the planet gear 34 are in an engaged state by pressing the pressure plate 36; when the electromagnetic clutch is not under the action of electromagnetic pressure, the gear end of the clutch body 35 and the planet gear 34 are in a separated state under the action of elastic pushing of the diaphragm spring 33 on the pressure plate 36.
The electromagnetic clutch in the above embodiment further includes an electromagnetic coil 37, an electromagnetic coil controller, a diaphragm spring 33 and a guide iron block 38, the guide iron block 38 is fixed perpendicularly to the surface of the pressure plate 36, the electromagnetic coil 37 is fixed on the guide iron block 38, and the electromagnetic coil controller is connected to the electromagnetic coil 37; the solenoid controller is for controlling the solenoid 37 to generate an electromagnetic force pressure against the elastic force of the diaphragm spring 33.
In specific implementation, the electromagnetic coil 37 controller is used for controlling whether the electromagnetic coil 37 is electrified, when the electromagnetic coil 37 is electrified, as shown in fig. 3, the electromagnetic force generated by the electromagnetic coil will drive the guide iron block 38 to move towards the spring compression direction, and further press the pressure plate 36 to drive the differential body to approach the planet wheel 34 until the differential body and the planet wheel 34 are in an engaged state, and at this time, the power output by the output end of the engine 1 can be transmitted to the front drive shaft 7 through the planet wheel 34. Conversely, when the solenoid 37 is de-energized, the diaphragm spring 33 will move the guide iron 38 in the opposite direction, forcing the pressure plate 36 to move the differential body away from the planet wheels 34, as shown in fig. 2.
The pressing plate 36 in the above embodiment includes an upper pressing plate and a lower pressing plate, which are symmetrically disposed along the front driving shaft 7, and the upper pressing plate and the lower pressing plate are respectively provided with the corresponding diaphragm spring 33 and the corresponding guide iron block 38. Through the setting of top board and holding down plate, can promote the stability of clutch body 35 gear end and planet wheel 34 switching control and the homogeneity of atress.
The embodiment further comprises a power output control unit which is respectively in signal connection with the engine 1, the generator 2, the power battery pack 4, the first differential mechanism 3 and the second differential mechanism 6;
the power output control unit is used for controlling the driving motor 5 to drive the second differential mechanism 6 to output power and controlling the engine 1 to drive the first differential mechanism 3 to output power when the running speed of the automobile is greater than a threshold value; the power output control unit is used for controlling the driving motor 5 to drive the second differential mechanism 6 to output power when the running speed of the automobile is not greater than the threshold value.
In specific implementation, various power input control logics can be preset. For example, when the vehicle speed is lower than the threshold value, the power battery pack 4 is controlled to output power to the second differential mechanism 6, when the vehicle speed is greater than the threshold value, the engine 1 is controlled to output power to the first differential mechanism 3, and when the output power of the engine 1 is greater than the power required by the first differential mechanism 3, the surplus power can be used for driving the generator 2 to generate power to the power battery pack 4, so that the power of the engine 1 can be utilized to the maximum.
