Kwindlela yokukhwela ibhayisekile, kukho igama abantu abaninzi abamele ukuba balivile, "ukuxhaphaka kokunyathela", igama elihlala likhankanywa. Kubathandi bokukhwela ibhayisekile, ulawulo olufanelekileyo lwesantya sephedali alunakuphucula kuphela ukusebenza kakuhle kwebhayisekile, kodwa lukwaphucula nokuqhuma kwebhayisekile. Ngaba ufuna ukwazi ukuba isebenza njani? Ngoko makhe sijonge ngakumbi ukubaluleka kwesantya sephedali kunye nendlela esinokuyiphucula ngayo amava ethu okukhwela ngokwandisa isantya sephedali.
Okokuqala, yintoni i-tread frequency
I-Treadle frequency ibhekisa kwinani leenguqu ngomzuzu ngexesha lokukhwela. Yiparameter ebalulekileyo yokulinganisa ukusebenza kakuhle kokukhwela, okuhlala kuchazwa njenge-Revolutions ngomzuzu. Inqanaba le-treading frequency lichaphazela ngqo isantya, amandla okukhupha kunye nesantya sentliziyo yomkhweli.
Okwesibini, ukubaluleka kokunyuka rhoqo
1. I-pedal frequency ephezulu ithetha ukuba i-pedal nganye inokuguqulwa ibe ngamandla okuya phambili, ngaloo ndlela inyusa ukusebenza kakuhle kokukhwela. Ngesantya esifanayo, i-pedal frequency ephezulu inokunciphisa ukudinwa kwemisipha, kuba amandla e-pedal nganye mancinci, izihlunu zinokululama ngcono.
2. Yehlisa uxinzelelo lwamalungu kunye nemisipha: Ukuphindaphindeka okuphantsi kwepedali kudla ngokuhamba kunye nokuphindaphindeka okuqinileyo, okwandisa umthwalo kwijoyinti yedolo kunye nemisipha kwaye sele kubangela ukuwohloka kwe-cartilage, okunokukhokelela ekwenzakaleni ekuhambeni kwexesha. Ukuphindaphindeka okuphezulu kwepedali kunokusasaza olu xinzelelo kwaye kunciphise umngcipheko wokwenzakala.
3. Ukuphucula ukusebenza kwentliziyo nokuphefumla: Ukubetha ngamandla okuphezulu kwentliziyo kudla ngokuhamba nesantya esiphezulu sentliziyo, nto leyo enceda ekuphuculeni ukusebenza kwentliziyo nokuphefumla kakuhle kwenkqubo yentliziyo.
4. Ziqhelise izakhono zokukhwela: Ngokuziqhelanisa ne-pedal frequency ephezulu, abakhweli banokulawula ngcono ibhayisekile kwaye baphucule izakhono zokukhwela, ingakumbi xa benyuka kwaye bekhawulezisa.
Eyesithathu, indlela yokuphucula ukuphindaphindwa kokunyathela
1. Ukukhetha ngokwesayensi umlinganiselo wegiya: Umlinganiselo wegiya ofanelekileyo linyathelo lokuqala lokuphucula isantya sokunyathela. Xa ukhwela kumhlaba othe tyaba, ungazama ukusebenzisa umlinganiselo wegiya ophezulu, ukuze ipedali nganye ijikwe lula, ngaloo ndlela uphucule isantya sepedali.
2. Ziqhelise ukupeda okuthambileyo: Ukupeda okuthambileyo nokuqhubekayo yeyona nto ibalulekileyo ekuphuculeni amaxesha okupeda. Xa upeda, isithende kufuneka sihlale sitshona kwaye unyawo lutyhalwe ngumbindi wonyawo, nto leyo enokunciphisa ukulahleka kwamandla kwaye iphucule ukusebenza kakuhle kokupeda.
3. Uqeqesho lwexesha: Uqeqesho lwexesha yindlela esebenzayo yokwandisa amaxesha okunyathela. Ngokutshintsha imijikelo yokunyathela ephezulu nesezantsi, unokunyusa ukuqina kwemisipha kunye namandla, ngaloo ndlela wonyusa amaxesha okunyathela aqhelekileyo.
4. Gcina indlela efanelekileyo yokukhwela: Indlela efanelekileyo yokukhwela inokunceda abakhweli ukuba badlulise amandla ngempumelelo kwaye banciphise inkunkuma yamandla. Gcina umqolo wakho uthe tye kwaye iingalo zakho zikhululekile ukuze ulawule ngcono ibhayisekile kwaye unyuke rhoqo.
Isine: Kufanelekile kangakanani ukunyathela rhoqo?
Uninzi lwabakhweli abanamava baya kukuxelela ukuba ukugcina iinguqu ezingama-80 ukuya kwezili-100 ngomzuzu (RPM) luluhlu olufanelekileyo, olungagcini nje ngokuphucula ukusebenza kakuhle kwepedali, kodwa lukwanciphisa umthwalo emadolweni nasezihlunwini, okwenza ukukhwela kwakho kube lula kwaye kube kwendalo ngakumbi.
Kutheni ukhetha olu luhlu? Kuba ukuphindaphindeka kwepedali ephantsi kakhulu kuthetha ukuba kufuneka usebenzise amandla amaninzi ukupedali, oku kukhokelela ekudinweni kwemisipha ngokulula; Iipedali eziphezulu zinokucinezela izihlunu zemilenze yakho kakhulu, nto leyo engayi kunceda uhambo olude. I-treadle ye-80-100 RPM ithathwa njengohlobo lokulinganisela, olunceda umkhweli ukuba agcine isantya esizinzileyo kwaye abe namava angcono okuzonwabisa ngokukhweli.
Esi sisikhokelo nje esiqhelekileyo. Enyanisweni, isantya sokunyathela esifanelekileyo kufuneka siqwalasele imeko yomzimba yomntu, indawo yokukhwela, kunye nohlobo lwebhayisekile kunye nezinye izinto. Umzekelo, xa unyuka intaba, kunokufuneka ukunciphisa isantya sokunyathela ukuze wonyuse i-torque, ngelixa kwicandelo elithe tyaba okanye elisezantsi, isantya sokunyathela singanyuswa ukuze wonyuse isantya.
Ukuphindaphinda kwenyathelo yiparameter ebalulekileyo ekukhweleni, echaphazela ngokuthe ngqo ukusebenza kakuhle kunye nokusebenza kokukhwela. Ngokwandisa ukuphindaphinda kwepedali, abakhweli banokonwabela ukukhwela ngcono, bandise isantya sokukhwela ibhayisekile, banciphise umngcipheko wokwenzakala, kwaye baphucule ukusebenza kwentliziyo nokuphefumla. Ngokuziqhelanisa noqeqesho, wonke umntu unokufumana isantya esifanelekileyo, ngaloo ndlela ephucula amava okukhwela.
Kwangaxeshanye, ndinqwenela ukuba ungafumana indlela yakho yokuqhuba ipedali ukuze ujongane nemingeni eyahlukeneyo!
