China ndeimwe yemarudzi mana akare. Unyanzvi hwekare hweChina hwaive hunoshamisa zvikuru, uye zvigadzirwa zvina zvakava nepesvedzero huru pazvizvarwa zvaizouya. China zvakare ndiyo nyika yakatanga kugadzira nekugadzira mabheya. Kare makore anodarika 4 000 apfuura, motokari dzakaoneka kuChina ndokutanga kuisa mabheji anotsvedza. Munguva yeZhou Dynasty, kushandiswa kwemafuta emhuka kubereka tekinoroji yekuzora kwakagadzirwa. Munguva yeWaring States Period, China zvishoma nezvishoma yakatanga kugadzira shaft tiles nesimbi. Guo Shoujing, musayendisiti muYuan Dynasty, akanga atanga tekinoroji yerutsigiro (turntable bearing) tekinoroji. MuQing Dynasty, cylindrical roller bearings yakagadzirwa mune yemazuva ano inotakura chimiro. Munguva yeRepublic of China, China zvishoma nezvishoma yakatanga kugadzirwa kwakawanda uye kugadzirisa mabheji, uye yakagadzira Wafangdian, Shanghai maviri anobereka mabhesi ekugadzira uye ekugadzira. Mushure mekuvambwa kweChina's Republic of China, indasitiri yekutakura yeChina yakakura nekukurumidza, uye pakupedzisira yakaisa maitiro ese ezvino.kuvandudzwa kweindasitiri yekubereka. Kunyangwe China yatove yechitatu yakakura kutakura kugadzirwa uye kutengesa nyika munyika.

Nekukurumidza kusimudzira matekinoroji epamusoro uye matsva akadai seaerospace, indasitiri yenyukireya, komputa yemagetsi, optical uye electromagnetic zviridzwa, nemichina chaiyo, indasitiri inotakura nyika inoratidza danho razvino resainzi uye tekinoroji yapinda munguva itsva yehunyanzvi hwekugadzira. tekinoroji, inokurumidza kusimukira mhando, kusimbisa zvine simba kuita, kurongeka, uye kuwedzera kukura uye kukwana.
Nekuenderera mberi kwekuenderera mberi kwehupfumi hweChina uye nekuenderera mberi kwekuvandudza otomatiki, izvo zvinodikanwa zvemuenzi zvichange zvichikwira nekukwira, uyezve kuita uye tekinoroji zviyero zvechikwata chinotakura zvichakwira nekukwira, zvigadzirwa zvitsva zvinoramba zvichibuda, kudiwa. zvichange zvisingadzivisiki kukura uye kukura.
Nyika inoenderera mberi nekuwedzera kuchengetedza uye kuderedza kuburitsa simba uye kuvaka nharaunda inochengetedza simba zvirokwazvo ichakurumidza kukurumidza kushandura nzira yekuchengetedza simba uye kuderedza kushandiswa kwemaindasitiri echinyakare. Pamusoro pezvo, kusimudzira kukurumidza kusimudzira kweindasitiri yesimba idzva kuchaunza mikana mikuru yekufambira mberi kweindasitiri yekubereka. Naizvozvo, iyo indasitiri inotakura icharamba ichikura nekukurumidza mune ramangwana.
