Embodiment Construction

[0018] Below in conjunction with accompanying drawing and specific embodiment the present invention will be further described:

[0019] Based on a pneumatic hybrid power transmission system and control method proposed by the present invention, a miniature car with a displacement of 1.0 L was tested for refitting. like figure 1 As shown, the system consists of the following components:

[0020] 1) Main power transmission system:

[0021] It mainly includes a 1.0L gasoline engine (18), a gasoline engine control unit (6), a 5-speed manual transmission (15), a differential (13), a brake (11), and a driving wheel (10). After modification, the internal combustion engine and the engine transmission are connected by an overrunning clutch, and the clutch can transmit a maximum torque of 100Nm.

[0022] 2) Brake energy recovery system:

[0023] It mainly includes a power coupling device (14), an electromagnetic clutch (17), a 15kW air compressor (16), and an air pressure accumulator...

Abstract

The invention relates to a pressure hybrid power transmission system and a control method, in particular to a motor vehicle transmission system which utilizes, converts and stores energy of a motor vehicle power and transmission system and realizes double power synergy drive of an internal combustion engine and an air motor, and a control method, and belongs to the technical field of vehicle hybrid power. The system consists of an internal combustion engine, a hybrid power control unit, a compressor, a low-power air motor, an internal combustion engine control unit, an overrunning clutch, a high-power air motor, a speed changer, a slave cylinder air evacuation valve, a driving wheel, a brake, a brake slave cylinder, a dynamic coupling device, an electromagnetic clutch, a pneumatic accumulator pressure sensor, a pneumatic accumulator, an air horn and an electromagnetic valve and can recycle the braking energy of a vehicle in a pneumatic energy mode. A pressure system and the internal combustion engine are controlled by an electronic control unit to enable the internal combustion engine to often work in the high-efficiency low-emission region so as to effectively improve the utilization rate of fuel oil of the internal combustion engine, reduce fuel oil consumption and exhaust emission and realize energy conservation and emission reduction of the motor vehicle.

Description

technical field [0001] The invention relates to a pneumatic hybrid power transmission system and a control method, in particular to the energy utilization, conversion and storage of the motor vehicle power and transmission system, and belongs to the technical field of vehicle hybrid power. Background technique [0002] Environment and energy have become a hot topic at present. In the past century, people have used a large amount of mineral resources, such as coal and oil, which has also produced a large number of harmful substances and brought harm to the environment while promoting the progress of human society. According to reports, the average global temperature from 1981 to 1990 was 0.48°C higher than that of 100 years ago. Global warming has also caused various negative effects. According to statistics, about 60% of carbon dioxide greenhouse gas emissions come from the automobile industry and related industries, which shows the space for energy saving and emission reduc...
