Ko te punaha whakatara hau kei runga i nga momo huarahi rereke me te tohu o te puoro tawhiti, ka whakatauhia e te rorohiko haerenga te huringa o te teitei o te tinana, katahi ka whakahaere i te hau hau me te rewharewha ki te whakakopeke aunoa, ki te whakaroa ranei i te puna, na reira te whakaiti, te whakanui ake ranei i te waahi whenua o te tahuhu. , kia pai ake ai te pumau o te tinana o te waka tere-tere, te kaha ranei o nga tikanga huarahi uaua.
Ko te kaupapa mahi o te kaitapahi pneumatic ko te whakarereke i te teitei o te tinana ma te whakahaere i te pehanga hau, kei roto ko te rapa elastic airbag wiri wiri, te punaha whakahaere pehanga hau, te taaka rokiroki hau me te punaha whakahaere hiko.
Hangaia te Whakatarewatanga o te rangi he papamuri
Mai i tona whanautanga i waenganui o te rau tau 1800, kua eke te whakatārewatanga hau i te rau tau o te whakawhanaketanga, a, kua wheakohia e ia "te whakatārewatanga hiato puna-pueke hau-pneumatic → whakatārewatanga hau hau kaha → whakatārewatanga hau ki tonu i te hau (arā, te whakatārewatanga o te hau e whakahaeretia ana e te ECAS). .
I tenei wa, kei te whakauru haere me te whakamahi i etahi motika waka rererangi, penei i a Lincoln i te United States, Benz300SE me Benz600 i Tiamana, me etahi atu. e hiahia ana kia nui te awangawanga), ko te whakamahi i te aukati hau ko te mea anake te whiringa.
