【文章內(nèi)容簡(jiǎn)介】 的傳遞機(jī)構(gòu)，把力由電機(jī)齒輪的轉(zhuǎn)動(dòng)轉(zhuǎn)化成拉線方向上力。其齒輪結(jié)構(gòu)的工作原理如右圖電機(jī)帶動(dòng)拉線所在的外齒輪機(jī)構(gòu)和內(nèi)齒輪機(jī)構(gòu)旋轉(zhuǎn)，因?yàn)樾D(zhuǎn)方向相反，帶動(dòng)連接在內(nèi)外齒輪機(jī)構(gòu)的拉線運(yùn)動(dòng)，實(shí)現(xiàn)駐車。 gear mechanism. Different manufacturers EPB work principle of this part of the mechanism is not necessarily the same but the effect is the same. Is a force transmission mechanism, the force by the rotation of the motor gear into pull direction force. The working principle of gear structure such as the right motor drives the pull of outer gear mechanism and inner gears rotate, for rotating in the opposite direction, drive the cord attached to the inside and outside gear mechanism movement, parking. 。ECU用來(lái)控制EPB對(duì)外的信息交流和反饋。傳感器用來(lái)感應(yīng)拉力的大小。 ECU and the sensors. ECU is used to control EPB foreign exchange of information and feedback. The size of the sensor to sense tension. 4 EPB總成的工作原理和其功能的實(shí)現(xiàn)原理4 EPB work principle and the realization of the function of the principle of assembly 。拉線式EPB工作原理為：通過(guò)開關(guān)給ECU一個(gè)通斷信號(hào)，EPB的ECU控制電機(jī)進(jìn)行旋轉(zhuǎn)，然后由內(nèi)部的齒輪機(jī)構(gòu)把此力輸出到拉線上，由拉線帶動(dòng)制動(dòng)器進(jìn)行駐車。 EPB assembly works. Guyed EPB work principle is: through the switch to ECU an onoff signal, EPB ECU to control motor rotation, and the internal gear mechanism to put the power output to the guy, the guy drive the parking brake. EPB principle of realization of each function （1）基本功能。最基本的功能，靜態(tài)釋放和靜態(tài)駐車功能，通過(guò)按鈕駐車和解除駐車此工作原理簡(jiǎn)單，也就是上面的EPB工作原理。(1) basic function. And the static and the most basic function, the static release parking function, through the button in the car and lifted parking the principle is simple, also is the working principle of the EPB. ?。?）EPB賣點(diǎn)之一的動(dòng)態(tài)功能。當(dāng)車在行車狀態(tài)，速度大于12km/h,若按下EPB按鈕，ECU指揮馬達(dá)帶動(dòng)拉線駐車，當(dāng)車輪要抱死，有滑移的傾向時(shí)，ECU通過(guò)CAN得到這個(gè)信號(hào)后，會(huì)使拉線力減小，以便不使車輪抱死，如此循環(huán)，直至車停下為止。雖然EPB有此功能，但各個(gè)EPB廠家，并不推薦客戶把EPB當(dāng)作行車制動(dòng)器使用，并且還明確要求客戶，此功能只能在常規(guī)制動(dòng)器失效或不可使用踏板的緊急情況下才能使用，這是因?yàn)樵谛熊囍?，駐車制動(dòng)器啟動(dòng)后，那么就把制動(dòng)力全部加在后輪，對(duì)后制動(dòng)器的損害是很大的。(2) EPB one selling point of dynamic capabilities. State when the car in drive, speed is greater than 12 km/h, if the EPB button, motor drive the guy39。s car ECU mand, when the wheels to lock, have a tendency to slip when the ECU by CAN get the signal, CAN make the pull force is reduced, so as not to make the wheel lock, so circulates, until stopped. The EPB has this function, but each EPB manufacturer, don39。t remend customer to EPB as vehicle brake is used, and customer also made clear requirements, this functionality can only be used in conventional brake failure or peda
