Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to fig. 1-2 in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The plug-in hybrid heavy-duty tractor chassis (shown in fig. 1) has a front axle 10, a middle axle 6 and a drive axle 5 which are arranged on a frame 4 in sequence from front to back.
A saddle 3 is arranged between the middle axle 6 and the drive axle 5 and on the upper part of the frame 4. Trailer pressure acts on the saddle 3 flat plate, and the driving safety and the stability of the trailer are ensured.
(with reference to fig. 2) an engine 18 is arranged at the center of the upper part of the front axle 10; the center of gravity is ensured to be stable. The rear end of the engine 18 is connected with the input end of the drive axle 5 through a motor 16, a gearbox 15, a middle axle transmission shaft 22 and a drive axle middle transmission shaft 21 in sequence.
The invention is a parallel hybrid power system, integrates the advantages of pure electric vehicles and hybrid power vehicles, and can realize pure electric and zero emission driving; the driving range of the vehicle can be increased through the hybrid mode; the problems of endurance of the pure electric vehicle and high oil consumption of the traditional vehicle are effectively solved; meanwhile, the requirements of a user on hanging green plates, enjoying government subsidies and local road administration right can be met, and the method is another development direction of the new energy automobile. Under the conventional condition, the system has a basic acceleration assisting function, can make up the defect that the instantaneous response of the power of an engine is not fast enough, and improves the power performance of the whole vehicle.
Specifically, the method comprises the following steps: the hybrid power system has three driving modes of pure electricity, fuel oil and hybrid power, can save energy and reduce emission to the maximum extent, has high economic benefit, and meets specific requirements of users; the safety of the whole vehicle is improved through the aspects of battery thermal management optimization, brake recovery capacity, active speed limiting function design and the like.
The tractor is under pure electric mode: the invention is driven by the motor 16, the high-voltage battery device 2 provides power for the motor 16, and the vehicle can run for 50km when being fully loaded at a constant speed of 40km/h, thereby meeting the requirements of users on hanging green plates, enjoying government subsidies and local road administration rights.
In the fuel mode: the invention is driven by the engine 18, and the fuel tank 7 provides fuel for the engine 18, thereby effectively solving the problem of endurance of the pure electric vehicle.
In the mixed mode: the invention is driven by the motor 16, and is purely driven after starting, and the engine 18 does not participate in the work; until reaching the set speed, the engine 18 is switched in; when the vehicle speed is lower than the cut-in vehicle speed of the engine 18, the whole vehicle is in a main driving state of the motor 16. The motor 16 drive torque varies with throttle opening and speed: when the tractor needs to be accelerated, the high-voltage battery device 2 supplies power to the motor 16, and the motor 16 and the engine 18 drive the vehicle to run together, so that the tractor can be accelerated rapidly; meanwhile, compared with the traditional vehicle, the fuel consumption is reduced to some extent, and the fuel economy can be improved. When the tractor decelerates, if the tractor needs to decelerate slowly, the braking force is mainly provided by the motor 16, the motor 16 plays a role of a generator, part of braking energy is converted into electric energy, the electric energy is stored in the high-voltage battery device 2 after being processed by the charging circuit and used for supplying when needed, and the braking system does not participate in the process and is used for reducing the loss of braking components. If the tractor needs to be decelerated considerably in a short period of time, the braking system provides a braking force in conjunction with the electric motor 16. Compared with the conventional tractor, the tractor can obtain larger braking force due to the fact that the motor 16 participates in braking, namely the retarder device of the conventional tractor is equivalent, and the thermal attenuation condition of a braking system can be reduced.
