PTM - Pūnaehana Hoʻokele Porsche Traction
He ʻōnaehana ʻo Porsche Traction Management (PTM) me nā huila holoʻokoʻa me ka hoʻopaʻa uila multi-plate clutch, auto brake differential (ABD) a me ka anti-skid device (ASR). ʻAʻole hiki ke hoʻohele ʻia ka mana ma waena o nā axles mua a me hope ma o ka puʻupuʻu paʻa-nui, akā me ka ikaika ma o ka puʻupuʻu multi-plate.
ʻAʻole e like me ka paʻa paʻa paʻa-nui, e hoʻoponopono wale ana i ka ikaika o ka ikaika ke ʻokoʻa ka wikiwiki ma waena o nā axles mua a me hope, ʻoi aku ka wikiwiki o ka pane uila. Mahalo i ka nānā mau ʻana i nā kūlana hoʻokele, hiki ke komo i nā ʻano hoʻokele like ʻole: ʻike mau nā mea ʻike i ka helu o nā kipi o nā huila āpau, lateral a longitudinal acceleration, a me ke kihi hoʻokele. No laila, ʻo ka nānā ʻana o ka ʻikepili i hoʻopaʻa ʻia e nā mea ʻike āpau e hiki ke hoʻoponopono maikaʻi ʻia ka ikaika hoʻokele i ke axle mua a i ka manawa kūpono. Inā i ka wikiwiki e holo nā huila hope i ka pilikia o ka paheʻe ʻana, ʻoi aku ka maikaʻi o ka hoʻopaʻa ʻana o ka uila multi-plate, e hoʻohuli i ka mana i ke axle mua. I ka manawa like, pale ka ASR i ka wili huila. I ke kihi ʻana, ua lawa ka ikaika o ka hoʻokele ʻana i nā huila mua e pale aku i nā hopena maikaʻi ʻole i ka hopena ʻaoʻao o ke kaʻa. Ma nā alanui me nā coefficients like ʻole o ka friction, ʻo ka ʻokoʻa transverse hope, me ABD, hoʻomaikaʻi hou i ka traction.
Ma kēia ala, ʻo PTM, me Porsche Stability Management PSM, e hōʻoia i ka hāʻawi pololei ʻana i ka ikaika hoʻokele no ka hoʻokele maikaʻi loa i nā kūlana hoʻokele āpau.
ʻO nā pōmaikaʻi nui o ka PTM e ʻike nui ʻia ma nā alanui pulu a i ʻole ka hau, kahi mea kupanaha ka hiki ke holo.
ʻO ka hopena: palekana kiʻekiʻe, hana maikaʻi. He ʻōnaehana naʻauao loa.
