Vehicle multi-power driving system having re-use AC generating system

Abstract

The invention discloses a vehicle multi-power driving system having a re-use AC generating system. The vehicle multi-power driving system comprises a first vehicle axle and a first internal combustion engine. Power output of the first internal combustion engine is connected with a first transmission device; power output of the first transmission device is connected to the first axle; the vehicle multi-power driving system further comprises a second internal combustion engine; power output of the second internal combustion engine is connected to an AC generator; output of the AC generator is converted into a DC power supply via an alternative-direct current conversion device; DC output is connected with a driving motor via a cable; power output of the driving motor is connected to a second axle or wheels; the driving motor is electrically connected with a motor controller; and AC output of the AC generator is connected with electricity load of a vehicle. Enough power can be provided for vehicles driving in areas especially like grass land, deserts and mountainous areas; quick mobility and long-distance journey durableness can be achieved; assembled electricity load of large power can be met; electricity of vehicle-mounted generator can be reused in particular middle-large electricity reuse; the AC generator is characterized by small size, light weight and easy conversion to DC; and the vehicle multi-power driving system enables a generator to be placed on the vehicle.

Description

technical field [0001] The invention belongs to the technical field of automobile power, and in particular 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 realize multi-axle drive has better power output and good battery life, and is suitable for long-term driving in complex road conditions in the wild. However, the power of the above-mentioned multi-axle-driven vehicle is transmitted to each axle by the internal combustion engine through the transmission shaft system. The transmission shaft system is arranged under the chassis, so that the ground clearance of the chassis is relatively high. height, which limits the carrying capacity of the vehicle. [0003] Existing multi-power source drive technology is applied to vehicles, such as CN200910040759.1, which includes an engine installed on the fron...

AI Technical Summary

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
