Vehicle multi-power-source drive system with reuse alternating and direct current power generation system

Abstract

The invention discloses a vehicle multi-power-source drive system with a reuse alternating and direct current power generation system. The system comprises a first axle and a first internal combustion machine and further comprises a second internal combustion machine; the power output of the first internal combustion machine is connected with a first transmission device, the power output of the first transmission device is connected to the first axle, the power output of the second internal combustion machine is connected to an alternating current electric generator and a direct current electric generator, the output of the alternating current electric generator is connected with an electric load for uploading of a vehicle through a cable, and the output of the direct current electric generator is connected with a drive motor through a cable; the power output of the drive motor is connected to a second axle or connected to a wheel; the drive motor is electrically connected with a motor controller; the system can particularly meet the requirement that when the vehicle runs in outdoor areas such as the grassland, the desert and the mountain area, the sufficient power is provided for the vehicle, and rapid maneuverability and long-distance running can be achieved; the alternating and direct current double electric generators are adopted to generate electricity, the direct-current vehicle drive electricity supply and vehicle-mounted alternating-current electricity are not disturbed by each other, independent work can be achieved, joint work can be also achieved, the control method is simple, the ground clearance of the vehicle is reduced, the vehicle height is reduced, and the vehicle can conveniently carry other transportation tools or devices.

Description

Technical field [0001] The invention belongs to the field of automobile power technology, and specifically relates to a multi-power source driving technology for automobiles. Background technique [0002] Vehicle multi-axle drive technology has been widely used in vehicle drive. The traditional use of internal combustion engines to achieve multi-axle drive has good power output and good endurance, and is suitable for long-term driving in complex road conditions in the field. However, the above-mentioned multi-axle drive vehicle power is transmitted to each axle through the drive shaft system using the internal combustion engine. The drive shaft system is arranged under the chassis, so that the ground clearance of the chassis is relatively high. When the total height of the vehicle is constant, the vehicle compartment is restricted. The height of the vehicle limits the carrying capacity of the vehicle. [0003] Existing multi-power source drive technology application vehicles, suc...

Problems solved by technology

[0004] Although the above-mentioned engine + electric drive device realizes the independent drive of multiple power sources, the electric drive part uses the power battery as the power source.

There are the following problems with the power battery as the driving power supply: 1. The poor endurance of the power battery is a common defect at present; 2. The charging time of the power battery is long, and even with the fast charging technology now, it still cannot meet the demand; 3. More critical The most important thing is that there is no perfect charging system in cities and villages, which makes it difficult to widely use vehicles powered by power batteries, especially in areas where there is no power supply in the wild such as grasslands, deserts and mountainous areas. The above-mentioned electric drive devices cannot be realized at all; 4. The electric drive structure cannot meet the needs of the electric load on the vehicle with high power on-board
