Embodiment Construction

[0027] As shown in Figures 1 and 2, the vehicle structure of the electric drive vehicle mainly includes a vehicle frame 21, a control system part 11, a magnetic levitation track part, a driving control part, a braking part, and a battery pack 12 parts. The magnetic levitation crawler part constitutes the driving system, and a crawler belt 5 is respectively arranged on both sides of the vehicle frame 21. The driving system is a linear motor electromagnetic coil fixed on the vehicle frame 21 as the primary and a composite plate (linear motor secondary) embedded on the crawler belt 5 as the secondary. The left and right two linear motors 7 that are formed by two stages, the inner surface of the crawler belt 5 is covered with permanent magnets 3, and the vehicle frame 21 position opposite to the crawler belt permanent magnets 3 is equipped with permanent magnets 3 with the same polarity, and the array permanent magnets 3 and can The electromagnet 4 that adjusts the current forms a ...

Abstract

The invention discloses a magnetic suspension crawler typed linear motor power driving vehicle, comprising a frame, a driving system in the frame and a forward / steering / braking / backward control system. Two sides of the frame are respectively provided with a crawler; a magnetic suspension system is arranged between the crawler and the frame; the driving system is a left linear motor and a right linear motor which are formed by a primary driving system fixed on the frame and a secondary driving system embedded on the crawler; the electromagnetic coil windings of the left linear motor and the right linear motor are electrically connected with a controller through a frequency converter; the forward / steering / braking / backward control system comprises a pulling rod and a pedal which are corresponding to each other, and sensors which are connected with all the pulling rods and the pedals; the sensor is connected with the controller. The power driving vehicle of the invention simplifies mechanism transmission system and has the advantages of environmental protection, fast speed, low cg, strong passing capability, good safety, etc.

Description

technical field [0001] The invention relates to an electric vehicle, in particular to a magnetic levitation crawler linear motor electric drive vehicle. Background technique [0002] The 21st century will be the century of environmental protection. One of the most pressing needs of our time is an alternative clean, smart and environmentally friendly urban transportation system. Electric vehicles are a viable solution that can improve urban air quality and reduce dependence on fossil fuels. There are many reports about electric vehicles, but there are few reports about maglev vehicles, and there is only one case recently. For example, Japan's Eko Technology Development Company designed and produced a miniature magnetic levitation car model with a length of 52 cm, a width of 23 cm, a height of 14 cm, and a weight of 4000 grams, and successfully carried out a driving test on a straight-line distance of 26 meters. , up to 25 kilometers per hour. In the middle of all the whee...
