1、關(guān)鍵零部件技術(shù)發(fā)展滯后。可靠性是國(guó)產(chǎn)裝載機(jī)的主要問(wèn)題，如國(guó)外發(fā)動(dòng)機(jī)使用壽命8000h以上.液壓泵5000-8000h，液壓缸100-200萬(wàn)次，而我國(guó)僅分別為300oh, 200oh-30001、和60--80萬(wàn)次。與國(guó)外先進(jìn)零部件相比，性能落后、質(zhì)量不穩(wěn)定、可靠性低等，k套件落后己成為制約國(guó)內(nèi)裝載機(jī)質(zhì)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、產(chǎn)品更新?lián)Q代周期長(zhǎng)，產(chǎn)品技術(shù)含量較低。國(guó)外機(jī)電液信一體化、智能化、集成化、多功能等技術(shù)己成熟。國(guó)內(nèi)輪式裝載機(jī)開發(fā)主要為仿制，跟隨國(guó)外現(xiàn)有成熟機(jī)型.大部分核心技術(shù)要依靠國(guó)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、技術(shù)創(chuàng)新能力薄弱，市場(chǎng)快速反應(yīng)能力差。新產(chǎn)品開發(fā)周期長(zhǎng)，市場(chǎng)快速反應(yīng)能力差，用戶需求得不到滿足，其原因是對(duì)技術(shù)創(chuàng)新是從市場(chǎng)、研發(fā)、生產(chǎn)到商品化的系統(tǒng)工程認(rèn)識(shí)不足.以及技術(shù)創(chuàng)新機(jī)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.
