Description
Technical Field
The invention relates to a hybrid power system and a vehicle, and belongs to the technical field of new energy automobiles.
Background
Environmental pollution and energy crisis are increasingly prominent, and new energy automobiles are encouraged and supported by the nation as an alternative solution to transportation. Due to the technical disadvantages of batteries and electric motors, hybrid vehicles are attracting attention as a transition product from internal combustion vehicles to electric vehicles. Since the hybrid electric vehicle has a plurality of power sources, the coupling and switching between different powers become the key point of the new energy vehicle design.
The coupling mode among the power sources of the hybrid electric vehicle comprises a series connection mode, a parallel connection mode and a mixed connection mode. The series-parallel hybrid system has a significant performance advantage over the series hybrid system and the parallel hybrid system. Chinese patent document No. CN 206884721U discloses a three-shaft planetary gear hybrid power system and a vehicle including the same. In the scheme design, a locking clutch is arranged between a generator and a planet row, a two-gear AMT is arranged between a driving motor and the planet row, and a torsional damper is arranged between the engine and the planet row. But has the following disadvantages:
(1) the system is three parallel shafts, the requirement on radial space is high, and the system is not easy to arrange;
(2) the dual-motor drive cannot be realized, and the generator is only used for generating electricity and does not participate in the drive, so that the torque required by the main motor is large, and configuration waste is caused;
(3) when the pure electric drive is carried out, the generator rotates along with the pure electric drive at a high speed, and high-speed weak magnetic reaction can occur, so that energy loss is caused.
Disclosure of Invention
The invention aims to provide a hybrid power system and a vehicle, which are used for solving the problems that the hybrid power system in the prior art has high requirements on the performance of a motor and cannot easily meet the power requirements of a pure electric mode of the whole vehicle; and when the internal combustion engine is directly driven, the motor rotor generates weak magnetic reaction at high speed along with rotation, thereby consuming power and wasting energy.
In order to achieve the above object, the scheme of the invention comprises:
the invention discloses a hybrid power system, which comprises an engine and a drive axle, wherein an in-axle motor is arranged in the drive axle, and the in-axle motor is connected with an output mechanism of the drive axle through a clutch or a gear shifting mechanism with a neutral position; the power output end of the planet row is connected with the output mechanism of the drive axle; two power input ends of the planet row are respectively provided with a locking mechanism.
The integrated drive axle hybrid power system comprises two motors inside and outside an axle, wherein the outputs of the two motors are connected with a downstream power system after being coupled through a clutch or a speed change mechanism. When the power demand of the whole vehicle is not high, such as high-speed cruising or downhill road conditions, the vehicle can be driven by only using the in-axle motor, the power of the in-axle motor is transmitted to the main speed reducer through the clutch or the gearbox, and the main speed reducer drives a downstream power mechanism such as a differential mechanism. At the moment, a locking mechanism at the power input end of the planet row connected with the output shaft of the engine is locked, and power drives the off-bridge motor to rotate along with the planet row through a transmission system. When the whole vehicle has a large power demand, for example, when the vehicle starts or climbs a slope, the in-bridge and out-bridge motors work in a driving state at the same time, the locking mechanism at the power input end of the planetary row connected with the output shaft of the engine is locked, the power of the out-bridge motor is decelerated and torque-increased through the planetary row, then the power drives the downstream power mechanisms such as the main speed reducer, the differential mechanism and the like through the transmission mechanism, and meanwhile, the in-bridge motor drives the downstream power mechanisms such as the main speed reducer, the differential mechanism and the like through the gearbox. The output power of the two motors inside and outside the bridge is used for driving the vehicle after being coupled, so that the common driving of the two motors is realized, and compared with a single-motor hybrid power scheme, the requirements of the vehicle on performance parameters such as starting torque of a single motor are reduced, so that the requirements of the scheme on the motors are lower. Meanwhile, under the pure electric working condition, the input end of the planet row connected with the output shaft of the engine is locked through the locking mechanism, and the engine can be prevented from being reversely dragged. The problems of power loss and energy waste are solved under a certain working condition.
When the internal combustion engine is in a direct-drive mode, the input end of the planet row connected with the motor outside the bridge is locked, the power of the internal combustion engine is transmitted to a main speed reducer, a differential mechanism and other downstream power mechanisms after the speed reduction and torque increase of the planet row, at the moment, a clutch connected with the motor inside the bridge is disconnected, or a gearbox is arranged in a neutral position, the motor inside the bridge and the motor outside the bridge are both in a stop state, the high-speed follow-up rotation of the motor outside the bridge is avoided, and the high-speed weak magnetic reaction is prevented.
Further, the motor in the axle is connected with an output mechanism of the drive axle through a gear shifting mechanism with a neutral gear.
The in-axle motor is connected with a downstream power system through the gear shifting mechanism, on one hand, under the working condition that the out-axle motor and/or the engine are driven, the gear shifting mechanism can be placed in a neutral position to prevent the in-axle motor from rotating along with the rotation; on the other hand, more speed ratios are provided when the motor in the bridge is driven, and the adaptability of the motor in the bridge to different working conditions such as driving or kinetic energy recovery is improved.
Furthermore, a main shaft of the off-bridge motor is freely rotatably sleeved on a transmission shaft of the engine and is connected with a sun gear of the planet row; and a transmission shaft of the engine is connected with a planet carrier of the planet row.
The transmission shaft of the engine and the off-bridge motor are coaxially arranged, so that the space occupied by the system on the vehicle is reduced, the arrangement of the system on the vehicle is more facilitated, and the space of a chassis is saved.
Furthermore, a main shaft of the in-bridge motor is freely rotatably sleeved on a half shaft of the integrated drive axle.
The in-bridge motor and the half shaft of the integrated drive axle are coaxially arranged, so that the size of the drive axle is reduced, and the space utilization rate in the axle is improved.
The invention discloses a vehicle, which comprises an engine and a drive axle, wherein an in-axle motor is arranged in the drive axle, and the in-axle motor is connected with an output mechanism of the drive axle through a clutch or a gear shifting mechanism with a neutral position; the power output end of the planet row is connected with the output mechanism of the drive axle; two power input ends of the planet row are respectively provided with a locking mechanism.
Further, the motor in the axle is connected with an output mechanism of the drive axle through a gear shifting mechanism with a neutral gear.
Furthermore, a main shaft of the off-bridge motor is freely rotatably sleeved on a transmission shaft of the engine and is connected with a sun gear of the planet row; and a transmission shaft of the engine is connected with a planet carrier of the planet row.
Furthermore, a main shaft of the in-bridge motor is freely rotatably sleeved on a half shaft of the integrated drive axle.
