Na'urar auna birki ta mota - Nau'in B
Aikace-aikace:
Birki yana ɗaya daga cikin muhimman abubuwan da ke taimakawa wajen tuƙi cikin aminci ga mota, kuma aikinta yana da tasiri sosai kan amincin tuƙi da ƙarfin motar. Yawanci, ana gwada aikin birki bisa ga ƙa'idodin gwaji da cibiyoyi masu iko suka kafa. Hanyoyin gwaji na gabaɗaya sun haɗa da ƙananan gwaje-gwajen samfura da gwajin benci mara motsi. Ana amfani da ƙananan gwaje-gwajen samfura don kwaikwayon girma da siffofi na birki, wanda ke haifar da ƙarancin daidaito amma ƙarancin farashi. Ana amfani da su galibi don tantance kayan gogayya, kula da inganci, da haɓaka sabbin samfura.
Na'urar auna ƙarfin birki ita ce mafi inganci a gwajin ingancin birki, wanda zai iya nuna halayen aikin birki kuma a hankali ya zama babban abin dubawa na ingancin birki. Yana iya gwada tsarin birki a cikin yanayi mai sarrafawa wanda ke nuna ainihin duniyar.
Gwajin Dynamometer na birkin mota kwaikwaiyo ne na tsarin birki na motoci, wanda ke gwada ingancin birki, kwanciyar hankali na zafi, lalacewar layi, da ƙarfin birki ta hanyar gwaje-gwajen benci. Hanyar da ake amfani da ita a duniya a yanzu ita ce kwaikwayon yanayin birki na haɗa birki ta amfani da inertia na inji ko inertia na lantarki, don gwada aikinsa daban-daban. An tsara wannan injin dynamometer na nau'in rabawa don gwajin birki na motocin fasinja.
Fa'idodi:
1.1 An raba mai masaukin daga dandalin gwaji don rage tasirin girgizar mai masaukin baki da hayaniya akan gwajin.
1.2 An sanya ƙafafun tashi tare da saman mazugi na babban shaft, wanda ya dace don wargazawa da aiki mai dorewa.
1.3 Bencin yana amfani da silinda na lantarki na servo don tuƙa silinda na birki na farko. Tsarin yana aiki cikin aminci da aminci tare da daidaiton sarrafa matsin lamba mai yawa.
1.4 Manhajar bench za ta iya aiwatar da ƙa'idodi daban-daban da ake da su, kuma tana da sauƙin amfani da ita. Masu amfani za su iya tattara shirye-shiryen gwaji da kansu. Tsarin gwajin hayaniya na musamman zai iya aiki da kansa ba tare da dogaro da babban shirin ba, wanda ya dace da gudanarwa.
1.5 Ka'idojin gwaji masu aiki: AK-Master, SAE J2522, ECE R90, JASO C406, ISO 26867, gwajin GB-T34007-2017 da sauransu.
