製動器製動機構

    製動器製動機構

    按(an)在(zai)汽(qi)車(che)上(shang)安(an)裝(zhuang)位(wei)置(zhi)的(de)不(bu)同(tong)
，駐(zhu)車(che)製(zhi)動(dong)裝(zhuang)置(zhi)分(fen)中(zhong)央(yang)駐(zhu)車(che)製(zhi)動(dong)裝(zhuang)置(zhi)和(he)車(che)輪(lun)駐(zhu)車(che)製(zhi)動(dong)裝(zhuang)置(zhi)兩(liang)類(lei)。前(qian)者(zhe)的(de)製(zhi)動(dong)器(qi)安(an)裝(zhuang)在(zai)傳(chuan)動(dong)軸(zhou)上(shang)，稱(cheng)為(wei)中(zhong)央(yang)製(zhi)動(dong)器(qi)；後者和行車製動裝置共用一套製動器
，結構簡單緊湊
，已在轎車上得到普遍應用。

    這zhe種zhong製zhi動dong器qi將jiang一yi個ge作zuo行xing車che製zhi動dong器qi的de盤pan式shi製zhi動dong器qi和he一yi個ge作zuo駐zhu車che製zhi動dong器qi的de鼓gu式shi製zhi動dong器qi組zu合he在zai一yi起qi。雙shuang作zuo用yong製zhi動dong盤pan的de外wai緣yuan盤pan作zuo盤pan式shi製zhi動dong器qi的de製zhi動dong盤pan，中zhong間jian的de鼓gu部bu作zuo鼓gu式shi製zhi動dong器qi的de製zhi動dong鼓gu。

    進jin行xing駐zhu車che製zhi動dong時shi，將jiang駕jia駛shi室shi中zhong的de手shou動dong駐zhu車che製zhi動dong操cao縱zong杆gan拉la到dao製zhi動dong位wei置zhi
，經jing一yi些xie列lie杠gang杆gan和he拉la繩sheng傳chuan動dong
，將jiang駐zhu車che製zhi動dong杠gang杆gan的de下xia端duan向xiang前qian拉la，使shi之zhi繞rao平ping頭tou銷xiao轉zhuan動dong，其qi中zhong間jian支zhi點dian推tui動dong製zhi動dong推tui杆gan左zuo移yi，將jiang前qian製zhi動dong蹄ti推tui向xiang製zhi動dong鼓gu。待dai前qian製zhi動dong蹄ti壓ya靠kao到dao製zhi動dong鼓gu上shang之zhi後hou，推tui杆gan停ting止zhi移yi動dong，此ci時shi製zhi動dong杠gang杆gan繞rao中zhong間jian支zhi點dian繼ji續xu轉zhuan動dong。於yu是shi製zhi動dong杠gang杆gan的de上shang端duan向xiang右you移yi動dong，使shi後hou製zhi動dong蹄ti壓ya靠kao到dao製zhi動dong鼓gu上shang
，施shi以yi駐zhu車che製zhi動dong。

    解(jie)除(chu)製(zhi)動(dong)時(shi)
，將(jiang)駐(zhu)車(che)製(zhi)動(dong)操(cao)縱(zong)杆(gan)推(tui)回(hui)到(dao)不(bu)製(zhi)動(dong)的(de)位(wei)置(zhi)，製(zhi)動(dong)杠(gang)杆(gan)在(zai)卷(juan)繞(rao)在(zai)拉(la)繩(sheng)回(hui)位(wei)彈(dan)簧(huang)的(de)作(zuo)用(yong)下(xia)回(hui)位(wei)，同(tong)時(shi)製(zhi)動(dong)蹄(ti)回(hui)位(wei)彈(dan)簧(huang)將(jiang)兩(liang)製(zhi)動(dong)蹄(ti)拉(la)攏(long)。
