Pure electric dual-mode charging motor coach

Abstract

The invention discloses a pure electric dual-mode charging motor coach, which comprises coach body face plates, coach body frameworks, a driving system, an air conditioning system, a drive system and a charging device, wherein the coach body frameworks are made of light metal and glued by concave-convex circular grooves prior to being riveted with rivets. A light alloy main beam is arranged at a joint of a top framework and a middle coach body, the chassis framework is integrally formed by connecting a plurality of vertical column beams with the light alloy main beam on the upper portion of a coach body, the driving system is a high-torque three-phase asynchronous motor which is low rotation speed and additionally provided with a voltage-stabilizing circuit device, a gearbox of the drive system is decreased by 1-2 gears of gear ratio but increased in high-gear gear ratio and is used for the electric motor coach matched with a special rear axle for the electric motor coach, and the air conditioning system comprises two small-power air conditioning compressor motors, two air conditioners and a temperature control system arranged in the motor coach. The pure electric dual-mode charging motor coach is light, energy-saving, stable in structure, fine in safety, noise-insulating and long in service life, operating and manufacture costs are greatly reduced, and the cost performance is improved.

Description

technical field [0001] The invention relates to a bus, in particular to a pure electric dual-mode charging bus. Background technique [0002] Pure electric vehicle is a new technology in the field of automobile manufacturing that has emerged in recent years. It is revolutionary and its purpose is to achieve substantial energy saving and emission reduction. The technical routes and development ideas usually adopted by pure electric vehicles at home and abroad. The body part, transmission and braking, steering part and air-conditioning part are all manufactured using the technology and method of traditional automobiles, and are charged by fixed-point charging piles. [0003] Because electric vehicles continue to use traditional vehicle technology and the two are not compatible, coupled with the existing electric drive and electronic control system technology, its energy consumption has no advantage over traditional vehicles, and in addition, the battery used as a vehicle powe...

AI Technical Summary

Problems solved by technology

[0003] Because electric vehicles continue to use traditional vehicle technology and the two are not compatible, coupled with the existing electric drive and electronic control system technology, its energy consumption has no advantage over traditional vehicles, and in addition, the battery used as a vehicle power supply is large in size and heavy in weight , high cost, resulting in low cost performance, poor promotion, and defects and deficiencies

[0004] Traditional electric buses generally have the following disadvantages: 1. The weight of the body is relatively large, generally around 16 tons. The heavier the body, the higher the energy consumption; 2. The drive motors of existing electric buses are unreasonably matched and consume too much power , the battery used as a vehicle power supply is large in size, heavy in weight, and high in cost, and the price ratio of car purchase and operation is much higher than that of traditional buses; Driving in the city has no conditions and does not allow high-speed driving. Its speed is relatively slow, generally not exceeding 50km / h, while the maximum speed of existing electric buses is generally about 80km / h. The transmission system designed at this speed consumes The energy is also relatively large, which is undoubtedly a waste for the operation of the city; 4. The air-conditioning system of the existing electric bus also continues to use the air-conditioning system of the traditional bus. Power consumption accounts for one-third, or even 50%, so it must be improved; 5. The existing power battery is used as a vehicle power supply, which is too large and occupies 30% of the passenger space. 25% of the total weight of electric vehicles, its cost is too high, generally accounts for about 42% of the total cost of electric vehicles, and it depends on the government's huge investment in the construction of charging piles, it is difficult to promote on a large scale
