摘要
燃料电池汽车是目前唯一能做到真正“零排放”的新能源汽车,同时在动力性上又能和传统汽车相媲美;然而,燃料电池汽车在续航里程上相比于传统客车还存在着不足,同时,氢气的制备、运输和储存技术还不够成熟且成本较高,加氢站无法大规模建设。基于以上原因,燃料电池汽车更适用于城市公交车。
本文基于对给定的燃料电池公交车的设计要求,对汽车进行了整车参数选型匹配、各系统选型匹配计算、外形选型以及整车底盘的总布置设计。
首先,根据本次设计对燃料电池公交车的设计要求,参考市面上某款成熟的燃料电池公交车的设计,确定了整车的参数,包括空载质量、满载质量、最高车速、轴距、轮距等参数;对燃料电池公交车的外形进行选型,为后续的设计打下基础。
其次,对客车的驱动系统、制动系统、前后悬架、转向系统进行选型匹配计算,重点是驱动系统和制动系统的设计。确定整车的驱动形式、对电机、燃料电池和动力蓄电池等进行选型计算;确定制动系统的形式、对制动系统的制动力矩、制动系统储能供能装置等进行选型计算;对前后悬架、转型系统进行选型。
最后,在各系统设计完成后,对底盘进行总布置设计,将各系统总成合理地布置在底盘中的适当位置,使其能够正常工作。
本文对燃料电池公交车的整车设计、各系统的选型计算和底盘的布置进行了说明,可以为相关的整车总体设计提供参考。

Abstract
Fuel cell buses have the advantage of zero-emissions that other types of passenger cars cannot match. At the same time, they are comparable to traditional bus in terms of dynamics; however, fuel cell buses still have deficiencies in terms of cruising range compared to traditional bus. Meanwhile, The preparation, transportation, and storage technologies of hydrogen are not mature enough and the cost is high. Hydrogenation stations cannot be built on a large scale. Based on the above reasons, fuel cell buses are more suitable for city buses.
This article is based on the design requirements for a given fuel cell bus. The vehicle is selected for vehicle model selection, matching selection for each system selection, shape selection and overall layout of the chassis of the vehicle.
First of all, according to the design requirements for fuel cell buses in this design, with reference to the design of a mature fuel cell bus in the market, the parameters of the vehicle are determined, including the no-load quality, full-load quality, maximum speed, wheelbase, Wheelbase and other parameters lay the foundation for the design of subsequent systems.
Secondly, the passenger car's drive system, braking system, front and rear suspension, steering system selection and matching calculation, the focus is on the design of the drive system and braking system. Determine the drive form of the vehicle, calculate the selection of the motor, fuel cell, and power battery; determine the form of the brake system, the braking torque of the brake system, the energy storage device of the brake system, etc. ; Selection of front and rear suspensions and transformation systems.
Finally, after the design of each system is completed, the shape of the fuel cell bus is selected; the overall layout of the chassis is designed, and the system assemblies are rationally arranged in the proper position in the chassis so that they can work normally. [资料来源:http://doc163.com]
