1、关键零部件技术发展滞后。可靠性是国产装载机的主要问题,如国外发动机使用寿命8000h以上.液压泵5000-8000h,液压缸100-200万次,而我国仅分别为300oh, 200oh-30001、和60--80万次。与国外先进零部件相比,性能落后、质量不稳定、可靠性低等,k套件落后己成为制约国内装载机质量提高的主要因素。
Technical development of key components behind. Reliability is a major issue of domestic loaders, such as foreign hydraulic engine life over 8000h 5000-8000h, hydraulic cylinders 100-200 million,while the country were only 300oh, 200oh-30001, and 60 - 80 million times . Compared with foreign advanced components, performance backward, unstable quality, low reliability, k kit has become a major factor behind the loader to improve the quality of domestic constraints.
2、产品更新换代周期长,产品技术含量较低。国外机电液信一体化、智能化、集成化、多功能等技术己成熟。国内轮式装载机开发主要为仿制,跟随国外现有成熟机型.大部分核心技术要依靠国外公司。
Product long replacement cycle, low technological content of products. Foreign Hydromechatronics letter integration, intelligent, integrated, multi-functional technology has matured. Wheel loader developed primarily for domestic imitation, followed abroad existing mature models. Most of the core technology to rely on foreign companies.
3、技术创新能力薄弱,市场快速反应能力差。新产品开发周期长,市场快速反应能力差,用户需求得不到满足,其原因是对技术创新是从市场、研发、生产到商品化的系统工程认识不足.以及技术创新机制效率不高。
Technological innovation capability is weak, rapid market response is poor. Long development cycle of new products, rapid market response is poor, the user needs are not met, the reason is the lack of technological innovation from the market, research and development, production and commercialization of systems engineering knowledge.And technology innovation mechanism is not efficient.
