Anti-roll bar: abin da yake da kuma yadda yake aiki
Dakatar da mota tsari ne mai rikitarwa, wanda muka riga muka yi magana game da shi akan gidan yanar gizon mu Vodi.su. Dakatarwar ta ƙunshi abubuwa daban-daban na tsari: masu ɗaukar girgiza, maɓuɓɓugan ruwa, makamai masu tuƙi, tubalan shiru. Bar anti-roll yana daya daga cikin muhimman abubuwa.
Wannan labarin za a keɓe ga wannan na'urar, ka'idar aikinsa, amfani da rashin amfani.
Na'urar da ka'idodin aiki
A bayyanar, wannan sinadari wani karfe ne, mai lankwasa shi da siffar harafin U, ko da yake a kan manyan motoci na zamani siffarsa na iya bambanta da na U-dimbin yawa saboda ƙayyadaddun tsari na raka'a. Wannan sanda yana haɗa ƙafafun biyu na axle ɗaya. Ana iya shigar da gaba da baya.
Mai daidaitawa yana amfani da ka'idar torsion (spring): a cikin tsakiyar sa akwai bayanin martaba mai zagaye wanda ke aiki a matsayin bazara. A sakamakon haka, lokacin da motar waje ta shiga juyawa, motar ta fara juyawa. Duk da haka, ma'aunin torsion yana jujjuyawa kuma ɓangaren na'urar da ke waje ya fara tashi, kuma akasin ɗaya ya faɗi. Don haka yana fuskantar ƙarin juzu'in abin hawa.
Kamar yadda kake gani, komai yana da sauƙi. Domin mai daidaitawa ya yi aikinsa akai-akai, an yi shi daga nau'o'i na musamman na karfe tare da ƙarar ƙarfi. Bugu da kari, stabilizer an haɗa shi da tsarin abubuwan dakatarwa ta amfani da bushing roba, hinges, struts - mun riga mun rubuta labarin kan maye gurbin stabilizer strut akan Vodi.su.
Har ila yau, ya kamata a lura da cewa stabilizer iya kawai counteract load a kaikaice, amma a kan na tsaye (lokacin, alal misali, biyu gaban ƙafafun tuki a cikin rami) ko a angular vibration, wannan na'urar ba ta da iko kuma kawai gungura a kan bushings.
An gyara stabilizer tare da tallafi:
- zuwa subframe ko firam - ɓangaren tsakiya;
- zuwa ga katakon axle ko dakatarwa makamai - sassan gefe.
An shigar a kan duka axles na mota. Koyaya, nau'ikan dakatarwa da yawa suna yin ba tare da stabilizer ba. Don haka, akan mota tare da dakatarwar daidaitawa, ba a buƙatar stabilizer. Ba a buƙatar a kan gefen baya na motoci tare da katako mai torsion. Maimakon haka, ana amfani da katako da kanta a nan, wanda kuma ke da ikon yin tsayayya da torsion.
Ribobi da fursunoni
Babban fa'idar amfani da shi shine rage juzu'i na gefe. Idan ka ɗauki ƙarfe na roba na isasshen ƙarfi, to ko da a kan mafi girman juyi ba za ka ji nadi ba. A wannan yanayin, motar za ta ƙara haɓakawa lokacin yin kusurwa.
Abin baƙin ciki shine, maɓuɓɓugan ruwa da masu ɗaukar girgiza ba za su iya jure wa zurfin jujjuyawar da jikin motar ke fuskanta lokacin shigar da juyawa mai kaifi ba. Stabilizer ya warware wannan matsalar gaba ɗaya. A gefe guda kuma, yayin tuƙi kai tsaye, buƙatar amfani da shi yana ɓacewa.
Idan muka yi magana game da gazawar, to akwai kadan daga cikinsu:
- iyakancen wasa na dakatarwa;
- ba za a iya la'akari da dakatarwar gaba ɗaya mai zaman kanta ba - ƙafafun biyu suna haɗuwa da juna, ana yada damuwa daga wannan dabaran zuwa wani;
- raguwa a cikin ikon ketare na motocin kashe hanya - rataye diagonal yana faruwa saboda gaskiyar cewa ɗayan ƙafafun ya rasa hulɗa da ƙasa idan ɗayan, alal misali, ya faɗi cikin rami.
Tabbas, duk waɗannan matsalolin ana magance su yadda ya kamata. Don haka, ana haɓaka tsarin kula da shinge na anti-roll, godiya ga wanda za'a iya kashe shi, kuma silinda na hydraulic fara taka rawa.
Toyota yayi hadaddun tsarin don crossovers da SUVs. A cikin irin wannan ci gaba, stabilizer an haɗa shi da tsarin jiki. Na'urori masu auna firikwensin daban-daban suna nazarin hanzarin angular da mirgine motar. Idan ya cancanta, an katange stabilizer, kuma ana amfani da silinda na hydraulic.
Akwai ci gaba na asali a cikin kamfanin Mercedes-Benz. Misali, tsarin ABC (Active Body Control) yana ba ku damar rarraba gabaɗaya tare da abubuwan dakatarwa masu daidaitawa kaɗai - masu ɗaukar girgiza da silinda na hydraulic - ba tare da stabilizer ba.
Ana lodawa…
