Rigidity, pfungwa yakakosha mune yechirume lexicon, uye mune akasiyana siyana maficha. "Mukomana" anotora kakawanda kurohwa anonzi "akaoma"; munhurume anonzi ane ndebvu “dzakaoma”; mukadzi uya ane muviri wakanaka anoti “akasimba” (…); munhu asina simba anozviti “munyoro”; murume ane usimbe anozviti "nyoro". Zvakanaka, uye zviri nani kumira pano kana isu tatoziva kuti hurukuro ichaguma kupi ...
Asi vakawana pfungwa handiti? Kuoma kwakanaka, kupfava kwakaipa . Uye nemotokari chassis chinhu chimwe chete, asi nezvikonzero zvakasiyana.
Nguva imwe neimwe muvaki anotanga modhi itsva, kunouya nyaya yekuomarara-yakawedzera pano, yakawedzera ipapo, yakawedzera ipapo. Asi nei kuomarara kwechassis kwakakosha kudaro? Uyu ndiwo mubvunzo watichaedza kupindura nhasi.
Rigidity inokosha muzvinhu zviviri: kunyaradza uye maitiro . Iyo yakakura iyo chassis kusimba, iyo yakakura torsional kuramba yainopa. Torsional forces, zvakare, haisi chimwe chinhu kunze kwezvimanikidziro izvo chassis inopinda kuburikidza nebhureki, kukurumidza uye pamusoro pezvose (!) Makona nemakomba ayo motokari yakatarisana nayo. Izvo zvakakosha kuti mota irambe "yakasimba" kune idzi dzvinyiriro kuitira kuti kumiswa kushande nemazvo.
Kana mota yagadzirwa, chimwe chezvinhu zvinotariswa mukukura kwayo ndeyekumiswa kwegeometry. Suspension geometry inoraira kugona kwemota, kana kuti kwete, kuwedzera kuita kwetai uye kuve nechokwadi chekunyaradza uye kushanda zvakanaka.
Chii chinoitika kana chassis isina kuomarara zvakakwana ndechekuti inokotama pasi pesimba rekumanikidza kwataitaura nezvayo. Uye kana uchikotama, chii chichaitika ndechekuti kumisa geometry kunoshandurwa, ndiko kuti, kumiswa kuchashanda pane fungidziro iyo isina kugadzirwa.
Fungidzira bepa uye kumagumo ega ega fungidzira vhiri. Chero kudzvinyirirwa kunoitwa pabepa kunoita kuti imwe ye "mavhiri" irasikirwe nekubatana kwakaringana nepamusoro. Zvichitaurwa zviri nyore, izvi ndizvo zvakare nechassis.
Chimwe chinhu chinoita kuti kuomarara kupesvedzere kugarika kwekutasva. Iyo chassis haina kuomarara, iyo yakakura kuwanda kwekuzunguza kunosvika kune kabhini, nekuti iyo mota yese ichashanda sebhokisi resonance, ichiwedzera kudengenyeka uku kubva kumavhiri kusvika kune yese chimiro. Zvakasiyana, kana chassis yakaoma, mavibrations aya haasviki kabhini nekuti haakwanise "kufamba" kuburikidza nechimiro chemotokari.
Imhaka yezvikonzero izvi kuti mota dzinochinjika dzinotenderedza, kazhinji mune shoma "musanganiswa" nzira pane "yakajairika" mota dzavanobva kwadziri. Kushaikwa kwedenga pafuremu yechasi kwakafanana nekubvisa pamusoro pepiramidhi. Mamwe mavertices ese ane simba. Imhaka yezvikonzero izvi kuti vagadziri vanowedzera kusimbiswa kune chassis yevanotendeuka: kuyedza kudzoreredza kumwe kuomarara kwavakarasika pakabviswa denga.
