fig. 2 is a simplified model schematic of fig. 1.
Detailed Description
An embodiment of the vehicle is shown in fig. 1 to 2: comprising a frame (not shown in the figure), and a load, wheels 23 and a hybrid system arranged on the frame, the hybrid system comprising an engine 1, a first motor 3, a first coupling planetary row 4, a split planetary row 5 and a second coupling planetary row 6 arranged coaxially in sequence in the front-rear direction. The engine 1 is connected with a planet carrier 12 of a first coupling planet row through a torsional vibration damper 2, the first motor 3 is coaxially and fixedly connected with a sun gear 14 of the first coupling planet row, a gear ring 13 of the first coupling planet row is coaxially and fixedly connected with a planet carrier 16 of a split planet row, a first transmission shaft 21 is coaxially and fixedly arranged on a sun gear 17 of the split planet row, the first transmission shaft 21 is connected with the planet carrier 12 of the first coupling planet row through a first clutch 9, the first transmission shaft 21 is connected with the planet carrier 16 of the split planet row through a second clutch 10, and the gear ring 15 of the split planet row is in transmission connection with a load 8 through a first gear 18 and a second gear 19 which are meshed with each other. The planet carrier of the split planetary row is coaxially and fixedly provided with a second transmission shaft 22, the second transmission shaft 22 is in transmission connection with wheels 23, the planet carrier 20 of the second coupling planetary row is fixed on the second transmission shaft 22, the second motor 7 is coaxially and fixedly connected with the sun gear 21 of the second coupling planetary row, and the gear ring 11 of the second coupling planetary row is a fixed gear ring.
The vehicle is operated in electric-only (EV) mode, i.e., only the second electric machine, at low speeds (vehicle speed less than 30 km/h) and with a higher battery SOC (greater than 40%), and in hybrid mode (EVT) when the vehicle is at a vehicle speed greater than 30km/h or with a battery SOC less than 40%, i.e., the engine and the second electric machine are operated simultaneously. Under the EVT mode, the engine speed is regulated through the first motor to realize decoupling with the wheel speed, and the engine torque is coupled through the second motor torque to realize decoupling between the engine torque and the wheel torque, so that the engine can be controlled to work at an optimal working point.
When the load does not need to work, the first clutch and the second clutch are disconnected, the split planetary row is in a free state, and the engine and the load are in a disconnected state.
In EV mode, when load needs work, the engine starts and adjusts the engine speed to the same sun wheel speed of the split planetary row through the first motor, the first clutch is combined, and the engine drives the load to act through the transmission of the gear ring of the split planetary row to the load. The first motor adjusts the rotating speed of the engine, so that the impact-free switching between the engine and the load can be realized, and the smoothness of the vehicle is improved.
Under the EVT mode, when the load needs to work, if the difference between the rotation speed of the engine and the rotation speed of the sun wheel of the split planetary row is not large (the rotation speed difference is smaller than 100 rpm), the first clutch can be directly combined, if the difference between the rotation speed of the engine and the rotation speed of the sun wheel of the split planetary row is large (the rotation speed difference is larger than 100 rpm), the rotation speed of the engine can be adjusted to be the same as the rotation speed of the sun wheel of the split planetary row through the first motor, and the first clutch is combined, so that the working rotation speed of the load is determined by the rotation speed of the engine and the rotation speed of the second output shaft, and meanwhile, the air conditioner variable frequency control can be realized. If the load rotating speed is required to be equal to the engine rotating speed, after the first clutch is combined, the engine rotating speed can be regulated by the first motor to be the same as the second transmission shaft rotating speed, the second clutch is combined, the first clutch is disconnected, and after the speed regulation process is finished, the hybrid power system can be restored to the EVT mode operation. The invention realizes the controllable transmission of the engine and the load, reduces the power loss and improves the system efficiency, and the impact-free switching between the engine and the load transmission can be realized by adjusting the rotation speed of the engine by the first motor, thereby improving the smoothness of the vehicle. The transmission path of the engine to the vehicle and the transmission path of the engine to the load are shared by one section, so that the number of parts of the product can be reduced, the cost of the product can be reduced, and the space required for arranging the hybrid power system can be reduced.
In other embodiments of the invention, the load may also be a water pump in a cooling system; the engine, the first motor and the second motor can be arranged in different axes; when the load rotating speed does not need to be adjusted to be equal to the engine rotating speed, the second clutch is not required to be arranged; the second motor and the second coupling planetary rows may also be omitted if a purely electric mode of operation is not required.
Embodiments of the hybrid power system are shown in fig. 1 to 2: the specific structure of the hybrid system is the same as that described in the above-described vehicle embodiments, and will not be described in detail here.
