Ruzha rweTire. Chii chekutarisa kana uchitenga?

Ruzha rwematai runogona kukanganisa kunyange vatyairi vane murwere, kunyanya panzendo refu vachimhanya kupfuura 100 km/h. Ndechipi chikonzero chemheremhere uye chii chekutarisa kana uchitenga?

Tairi imwe neimwe yakasiyana, ine maitiro akasiyana, kushandiswa, nezvimwewo. Izvi hazvisi zvekuparadzanisa matayi muchando, zhizha, nguva yose, mitambo kana kunze kwemugwagwa, asi pamusoro pekusiyana mukati memhando imwe chete. Tai rega rega, nyangwe saizi yakafanana, hupamhi uye kumhanya, ine mafambiro echisikigo akasiyana. Hurukuro pahuwandu hwainozunungusa zvakanyanya, semuenzaniso, semugumisiro wekutyaira munzira dzisina kuenzana dzemugwagwa, etc. Muzviitiko zvakadaro, pane kutora mavibrations, inovakudza, ichigadzira imwe ruzha.

Kana iyo frequency yevhiri iri padhuze neiyo mota yakasikwa frequency, mhedzisiro iyi inotowedzera kutaurwa uye isingafadze. Nokudaro, kuenzanisa matai uye kushandisa pfungwa dzevamwe vatyairi hazviiti nguva dzose zvine musoro, nokuti iyo yakafanana tire modhi pane imwe mota icharatidza ruzha rwekuita zvakanaka, asi pane imwe mota ichave isingagamuchirwi. Iyi haisi mhosva yemugadziri wemavhiri kana kukanganisa mumotokari, asi kufanana kwehuwandu hwemotokari uye vhiri rataurwa pamusoro apa.

Ichi ndicho chimwe chezvikonzero nei vazhinji vanogadzira matayi vachigadzira mhando dzakagadzirirwa mota chaidzo. Iyi haisi nzira yekutengeserana chete, asiwo mugumisiro wekubatana uye kusarudzwa kwematairi kune zvakawanda. Ehe, dzimwe nguva vagadziri vanopira nemaune kunyaradza acoustic pavanenge vachigadzira matai ekuvandudza kubata, kukwevera mumigwagwa ine mvura, kunze kwenzira, nezvimwe.

Noise is noise, asi inobvepi? Sezvineiwo, kugadzirwa kweruzha kunokanganiswa kwete chete nekukweshana uye kuramba mugwagwa, asiwo nemhepo, vhiri pacharo, chimiro chetsika, kureba kwekutsika, nezvimwewo. Izvi zvinosanganisira kukanganisa kwezvivharo pamugwagwa uye kuparadzaniswa kwavo kubva pairi. Ruzha rwunokanganiswawo nemhepo yakadzvanyirirwa mumigero, ichikonzera kutinhira kwegiroove network, kutenheka kwemhepo yakawedzera kumashure kwevhiri, uye kusagadzikana mukuyerera pakati pevhiri arch nevhiri. Ehezve, kuderera kwakanyanya kudzvinyirira kuchavawo nemhedzisiro yakaipa paruzha rwakagadzirwa, asi uku ndiko kuregeredza kwemutyairi, uye kwete maitiro eimwe tai.

Matai akanyarara - akasiyana sei?

Nechepfungwa, zviri nani vhiri maererano nekubata, zvakanyanya kuwedzera mwero wekunyaradza uye ruzha. Matai ane yakakura, yakakura uye madiki profiles anozove asina kugadzikana uye ane ruzha. Zvinetso zverudzi urwu zvinogona zvakare kuve chimiro chematairi ane yakakwira mutoro index, saka kana izvi zvisingakodzeri, zviri nani kusaisa mari mune yakadaro mhinduro.

Kana kuita kwaidiwa kwakakwira kutyaira kunyaradza uye tsika yebasa, matai ane chimiro chepamusoro, diki uye saizi diki ndiyo ichava mhinduro yakanakisa - ivo vanozodzikisa mavibrations uye mapundu, pamwe nekuderedza ruzha rwunogadzirwa. Zvechokwadi, izvi zvinotungamirira pakuderera kwekuita kwekutyaira, i.e. mipumburu, kuzununguka, kusagadzikana kunyanya mumakona, kusabatika zvakanaka panguva yebhureki uye kumhanyisa, nezvimwe.

Noise mazinga anoderedzwa zvakare nemaitiro akadai seanotungamira asina nzvimbo dzakavharirwa, pamwe neakasiyana etread block maumbirwo ane asina kuenzana uye asymmetric hurongwa. Uye zvakare, zvakakosha kutarisisa kune akachinjika grooves, akaumbwa nenzira yekuti masuo avo uye kubuda kwavo hakuenderane nechekumucheto kwekutsika. Kupfava kwepamusoro kwekomboni yerubha kunodiwawo, asi izvi, zvakare, zvinogona kutungamirira kukurumidza kupfeka matayi.

Panyaya yematairi echando, maitiro ari pamusoro apa angave asingakwanisi, kunyanya kana zvasvika pakutsika maitiro, asi mhinduro dzemazuva ano dzinoreva kuti ruzha runokonzerwa nematairi echando rwakakwira zvishoma kudarika mutengo unofananidzwa matairi ezhizha. renji uye nemaparameter akafanana ehupamhi, saizi, nezvimwe.

Tire raiti ndiko kunobva ruzivo?

Paunenge uchisarudza matairi, iwe uchasangana neakakosha mavara akaiswa nevagadziri nevatengesi, pane iyo yakawanda yakakosha ruzivo inoratidzwa mumifananidzo. Inopa ruzivo nezve rolling kuramba (simba kirasi), wet grip uye ruzha mazinga.

- Rolling kuramba (simba rekirasi kana hupfumi hwemafuta)

Ruzivo urwu runozivisa mutengi kuti ingani rolling resistance inokanganisa hupfumi hwemafuta emotokari. Chikero chegiredhi chinotangira paA kusvika paG. Giredhi A ndiwo mubairo wakanaka uye zvinoreva kuti kutyaira nematayi akadaro kunoenderana nenharaunda uye kune mari.

Kubata kwemvura

Muchiitiko ichi, kunyorova kubata panguva yebhureki kunoongororwa. Chiyero chezviyero iAF, apo A ndiyo yakanakisa kuyero kune ipfupi chinhambwe chekumira. Kazhinji, vhiri rine yakakwirira rolling resistance rerating richava neakadzika wet grip rating uye zvakasiyana, kunyangwe paine mamwe mamodheru ane yakakwira A kana B.

-Kunze kuumburuka ruzha

Chiyero chekupedzisira chinoratidzwa negudzanzwi rine masaisai akawanda kubva pa1 kusvika pa3 uye nhamba inoratidza ma decibel. Chinhu chinonyanya kukosha ndeye nhamba ye decibels - hongu, iyo yakaderera iri nani. Kazhinji, kukosha uku kunodarika 70 dB, kunyangwe paine mhando dzine ruzha runosvika 65 dB.

Iyo yekupedzisira parameter pa label inoreva ruzha rwunoburitswa nevhiri riri kunze kwemota. Nepo kukosha kwe decibel kuchifanira kujeka kune wese munhu, iyo label inewo matatu-wave mutauri chiratidzo. Imwe wave inenge 3 decibels pazasi peyero yepamusoro yakagamuchirwa muEuropean Union, i.e. ne72dB. Pane musiyano mukuru pakati pe65 dB ne72 dB? Maonero anosiyana uye anowanzo kuve ega, saka zvakakosha kuti uwane ruzivo rwako wega.
