The Audi JW na Yuchai YC6105QC engines na-mere nke dị ọnụ ala, elu-ike obere earth ductile ígwè na ezigbo eyi na-eguzogide.
1. Ọdịdị nke crankshaft
Ihe mejupụtara crankshaft na-abụkarị nke ihu n'ihu, olu olu isi, crank, counterweight, akwụkwọ ndekọ mkpanaka njikọ na azụ azụ. Ihe mejupụtara crank bụ akwụkwọ ndekọ mkpanaka njikọ yana akwụkwọ akụkọ ndị bụ isi aka ekpe na aka nri. Ọnụ ọgụgụ nke crankshaft na-adabere na ọnụ ọgụgụ na nhazi nke cylinders. Ngwunye nke otu igwe cylinder nwere naanị otu crank; Ọnụ ọgụgụ nke crankshaft nke crankshaft nke in-line engine bụ ọnụ ọgụgụ nke cylinders; Ọnụ ọgụgụ nke cranks na crankshaft nke engine V hà na ọkara nke cylinders. A na-eji ogwe aka nke dị n'ihu nke crankshaft kwadebere ya na pulley, oge ihe eji eme ihe, wdg, nke a na-eji na-ebugharị mgbapụta mmiri na usoro valve. A na-etinye olu olu nke crankshaft na isi oche nke cylinder ahụ ma jiri ya kwado crankshaft. A na-eji akwụkwọ akụkọ njikọ na-ejikọta ya iji wụnye mkpanaka njikọ, na crank na-ejikọta akwụkwọ akụkọ ihe omimi nke isi na akwụkwọ akụkọ njikọ. Iji mee ka ike centrifugal guzozie mgbe crankshaft na-atụgharị, a na-enye nkwụsịtụ nguzozi na crankshaft. A na-enye flange njikọ na azụ azụ nke crankshaft iji jikọọ ụgbọ elu na crankshaft site na bolts. Iji mee ka mmanye akwụkwọ mmado njikọ, a na-agbapu akụkụ nke mmanụ mmanu site na akwụkwọ akụkọ shaft bụ isi gaa na akwụkwọ akụkọ njikọ njikọ. The integral crankshaft dị mfe na Ọdịdị, ìhè na arọ na a pụrụ ịdabere na-arụ ọrụ, na n'ozuzu adopts larịị bearings, nke ọtụtụ-eji na ọkara na obere engines.
2. Ụkpụrụ nhazi nke crank
Ọdịdị nke crankshaft na ọnọdụ ikwu nke ọ bụla crank na-adabere na ọnụ ọgụgụ nke cylinders, nhazi nke cylinders na usoro ọrụ nke cylinder ọ bụla. Mgbe ị na-ahazi usoro ọrụ engine, a ga-agbaso iwu ndị a dị ka o kwere mee:

3. Nhazi crank multi-cylinder nkịtị na usoro ọrụ
Nhazi nke crankshaft na crank nke in-line anọ-strok engine. The ọrụ nkeji Angle nke in-akara anọ-cylinder anọ-strok engine bụ 720 °/4 = 180 °, anọ crank na-ahaziri n'otu ụgbọelu, na engine na-arụ ọrụ usoro (ma ọ bụ mgbanye usoro) bụ 1-3- 4-2 ma ọ bụ 1-2-4-3. Ngwaọrụ mkpanye okirikiri na-arụ ọrụ nke a na-ejikarị nwere mpe mpe mpe mpe mpe mpe okirikiri okirikiri nwere oyi akwa mgbochi mgbochi, crankshaft isi nwere mgbanaka mgbanaka na mgbanaka mgbanaka nwere ụdị atọ. Mpempe ihe ntinye bụ mpempe akwụkwọ nchara nke ọkara nke nwere mgbochi mgbochi alloy oyi akwa n'èzí, nke etinyere n'ime oghere nke ahụ ma ọ bụ mkpuchi mkpuchi isi. Iji gbochie ntughari nke mpe mpe akwa ahụ, ihe nfegharị ahụ nwere mgbịrịgba rapaara n'ime oghere. Ụfọdụ mpe mpe akwa akwanye na-eji iberibe 4 mepụta oke okirikiri abụọ dị mma, ụfọdụ na-ejikwa oke 2. Akụkụ nwere mgbochi esemokwu ga-eche ihu n'akụkụ crankshaft.
