Tijaabada xanbaarsan: walxaha iyo hababka tijaabada muhiimka ah Kormeerka silashadu waa geedi socod muhiim u ah xajinta wax soo saarka iyo ilaalinta tayada.

Farqiga ugu weyn ee u dhexeeya cirbadaha cirbadda iyo xadhkaha kubbadda waa nooca iyo sifooyinka walxaha duuban ee ay isticmaalaan.

Shiinuhu waxa uu ka mid yahay waddama horraantii hore dunida u ikhtiraacay xadhkaha goosashada, waxaana qaab dhismeedka faashashku lagu qoray buugaag qadiimi ah oo Shiinaha ah. Marka laga eego dhinaca hadhaagii qadiimiga ahaa iyo xogta, Shiinaha kii ugu da'da weynaa ee la jaanqaadi jiray tusaalaha qaab-dhismeedka casriga ah ee duuban ayaa soo muuqday 221-207 BC (Qin Dynasty) ee Tuulada Xuejiaya, Degmada Yongji, ee Gobolka Shanxi.

Xirmooyinka rullaluistuyada wareega ah ayaa ah qaybaha ugu muhiimsan ee codsiyada warshadaha kala duwan, gaar ahaan mashiinada culus halkaas oo awoodda culeyska sare iyo awoodaha isku toosan ay muhiim u yihiin. Xirmooyinkan waxaa loogu talagalay inay qaadaan culeysyada axial ee hal jiha waxayna xamili karaan culeysyo shucaac ah, iyaga oo ka dhigaya doorasho la isku halleyn karo oo la isku halleyn karo oo dalbanaya xaaladaha hawlgalka.

Carwadii 135-aad ee Kanton ayaa 5-tii la soo xiray magaalada Guangzhou, taasi oo ka dhigan guul weyn oo u soo hoyatay bandhigga 1-aad ee Shiinaha. Iyada oo wadar ahaan 246,000 iibsade dibadda ah oo ka kala yimid 215 waddan iyo gobollo ah oo ka qaybqaatay shirka khadka tooska ah, daabacaadda carwadan waxay aragtay koror cajiib ah oo 24.5% ah kalfadhigii hore, iyadoo gaartay heerkii ugu sarreeyay. Dhacdadan oo muddo dheer laf-dhabar u ahayd ganacsiga caalamiga ah, ayaa mar kale muujisay awoodda aan la soo koobi karin ee ay u leedahay inay isu keento iibsadayaasha caalamiga ah iyo alaab-qeybiyeyaasha Shiinaha, taasoo kobcinaysa iskaashi faa'iido u leh labada dhinac iyo kobcinta dhaqaalaha.

Cunsurka rogrogmi kara waa rullaluistemadka dhexe ee cylindrical. Qaab dhismeedka gudaha ee rullaluistemadka cylindrical korsado rullaluistemadka habaysan barbar socda, oo waxaa jira spacer ama block go'doon u dhexeeya rollers, kaas oo ka hortagi kara janjeera ee rollers ama khilaaf u dhexeeya rollers, wax ku ool ah ka hortagga kororka torque wareega.

Carwadii 135-aad ee Shiinaha ee wax soo dejinta iyo Dhoofinta badeecadaha (Canton Fair) ayaa lagu qaban doonaa magaalada Guangzhou ee dalka Shiinaha laga bilaabo 15-ka Abriil ilaa 5-ta May, waxaana diyaargarowgu uu u socdaa si habsami leh.
