【導讀】制動器是產(chǎn)生阻礙車輛運動或運動趨勢的力（制動力）的部件。根據(jù)制動力矩產(chǎn)生的方式不同，制動器可。通常提及的制動器泛指摩擦制動器。目前各類汽車所采用的制動器可分為鼓式制動器和盤式制動器兩大類。軸上，其制動力矩需經(jīng)過驅(qū)動橋再分配到兩側(cè)車輪上，其一般只用于駐車制動和緩速制動。鼓式制動器有內(nèi)張型和外束型兩種。鼓的工作表面則是外圓柱面，目前只有極少數(shù)汽車將其用于駐車制動器。內(nèi)張型鼓式制動器主要由制動鼓。制動力矩的摩擦襯片）、固定銷及制動分缸等。制動時，位于制動鼓內(nèi)部的制動蹄片一端承受來自制動分缸。的促動力后，繞其另一端的支點向外旋轉(zhuǎn)，壓靠到制動鼓內(nèi)圓面上，進而產(chǎn)生摩擦力矩。其中，制動盤有通風式和實心式兩種；制動鉗主要有浮動鉗夾式（單活塞）、浮動叉式、固定鉗夾式。一方面，制動系統(tǒng)通過各種傳感器的實時監(jiān)控為制動系統(tǒng)的高效制動提供了更有效的安全保證；另

　　

【正文】 m, the car wheel system moves a revolve of machine a ponent solid pack on the car wheel or the half stalk, then make the motive Ju directly distinguishes a function on two side car wheels, it is generally used for going car system to move, can also and used for the second system to move(or meet an emergency to make to move) with halt car system to move。Central make to move a revolve of machine a ponent solid pack in spreading to move to fasten of spread and move stalk, it makes motive Ju to need to pass by to drive bridge to assign to again up two side car wheels, it general used for halting car system to move to alleviate to soon make to move. The drum type system39。s moving a machine to have is 2 kinds inside Zhang Xing2 and outside bunch former of make and move drum in cylinder noodles is work surface, on the car application extensive。The latter system moves the then outside cylinder noodles of the work surface of drum and the only very few few carses used for it to halt car system to move a machine the Zhang Xing2 Gu339。s type system move a machine mainly from make to move drum(shape pot, install Gu at the round up, and synchronously revolve with car wheel), make to move a hoof slice(the arc form parts, two per set, the hoof slice outside side glues to have creation system the friction Chen of the motive Ju a slice) and fix to sell and make an urn of move the cent...etc..While making to move Be located on to make to move make of drum inner part to move a hoof slice on carrying the Cu motive that the acceptance es from the urn which makes to move a cent, round it another a carry of the fulcrum outwardly revolves and press to depend to make to move the circle in the drum noodles up, then produce friction Ju.(make motive Ju) The dish type system moves a machine mainly from make to move dish(install at round the Gu top and car wheel to bee whole revolve) with make to move pliers(fix in changing direction stanza39。s etc. to hang a structure piece) to to move dish to have well ventilated type and solid type 2 kinds among them。Make to move the pliers mainly has already floated a pliers clip type(single piston), float a fork type and fixs the pliers clip type etc. a few kind. Move a way with the drum type system to pare, the dish type system moves the machine part of outside Lous of device and spread hot function like, reduce because of rub hot but produced to make to move decline phenomenon, make to move function more stable, so the modern car mostly adopted the dish type system to move a machine, but for lowering vehicle cost, parts of cars fore round adoption while the dish type system is moving a machine, empress the round still reserved the drum type system to move a machine. Make to move the system new technique Along with people to the car safety request of continuously raise to fly to soon develop with electronics technically, the car system in present39。s moving system has already taken place a revolution the other hand make to move system to pass various spread a feeling machine of solid hour supervise and control for made to move efficiently make of the system to move to provide more valid of safety assurance。Made to move system and the car other systems to constitute to maneuver the regional work of interleave on the other hand, at carry out intelligence to turn of make and move control of in the meantime, can also lower automotive energy depletion further。Moreover, along with new material with lately and structurally and in great quantities applied, the credibility which makes to move a system oneself also got a further improvement.
