第1章 绪 论
1.1我国半挂汽车列车生产制造发展现状
近些年来,随着国家经济的发展,交通运输业较为发达。就运输途径和形式来讲,当前世界各国均以公路运输为主。据有关资料介绍,美国公路运输占75%,英国为72.3%,俄罗斯为70%,而且车型在向大型和重型发展。随着公路运输事业的快速发展和汽车拖挂运输的普及,半挂汽车列车已经成为道路货运的主要运输工具,而半挂汽车列车制造业已经成为汽车工业的重要组成部分。为了促进我国半挂汽车列车生产制造的发展,并为用户提供优质产品,国内不少企业结合自己的生产实际需要,吸取国外同行业的先进经验,不断提高产品质量,开发具有科技含量高的产品(如多种专用的半挂汽车列车),为不同的运输客户服务,提高车辆的运输效率,增加生产经济效益,从而形成生产、销售、使用的良性循环。
我国商品的异地交流发展迅速,由于物流发展对半挂汽车列车的需求,半挂汽车列车生产制造规模不断扩大,产量增加,所以在国内专用车生产制造方面,半挂汽车列车比例不断增大,从多年前少量、小规模生产制造状况发展到今天,占据了专用车较大比例。以2002年为例,专用车生产分别为:厢式汽车:33104辆;罐式汽车:15595辆;起重举升车:7534辆;特种结构汽车:4530辆;其它改装汽车5498辆,而半挂汽车列车生产量为45752辆,居专用汽车生产量第一位。
半挂汽车列车产量在专用车中的比例不断增大,其主要原因在于半挂汽车列车具有价格比较低廉、运输效率快、载重量大,以及运费较低等优点。另外,半挂汽车列车和其他货车比较,在运输综合经济效益方面,有着更大的优势条件,特别是在码头、货物的集装箱运输方面表现得更为突出和明显。
与其他车型相比,半挂汽车列车毕竟属于技术含量较低,生产工艺简单,而且又是劳动密集型产品。特别是目前半挂汽车列车三大总成(车轴、支架、牵引销及支座)已经形成了专业化批量生产,外购关键总成,然后就能组装成型,所以半挂汽车列车生产厂家主要是自己制造车架。正是由于如此,使得进入行业的门坎较低,因此不少企业都把投资的目光转移到这一行业,而也正是这些企业的进入风潮导致如下局面:非正规厂家的产品粗制滥造,用户在产品质量和性能上得不到应有的保障,路边野店的拼装车以正规企业无法相比拟的价格优势几乎占据着半挂汽车列车市场的半壁江山;用户单纯看重价格,购买行为不规范,曾经一度造成半挂汽车列车生产和销售市场上的混乱局面。近几年来,经过国家“双超”治理,产品行业标准限定,以及半挂汽车列车单独上牌等相关管理措施出台与贯彻实施,半挂汽车列车生产制造技术以及产品质量有了不断的改善与提高。
