17、其是軍用車輛的行駛條件更為惡劣，這就要求增加車輛驅(qū)動輪的數(shù)目，因此，越野車多采用多軸驅(qū)動。例如，如果一輛單軸驅(qū)動車輛的兩驅(qū)動輪陷入溝中(這種情況在不良路面上經(jīng)常會遇到)，那么車輛就無法通過車輪與地面的摩擦產(chǎn)生驅(qū)動力而繼續(xù)前進。如果車輛是多軸驅(qū)動，即使部分驅(qū)動車輪無法正常驅(qū)動，其余驅(qū)動車輪仍可正常工作，車輛能夠繼續(xù)行駛。在多軸驅(qū)動車輛上，為了將輸出的動力分配給各驅(qū)動軸都設有分動器。分動器又稱為分動箱，其基本結(jié)構(gòu)和變速箱相似，是一個齒輪傳動系統(tǒng)。分動器裝于多橋驅(qū)動汽車的變速器之后，用于傳遞和分配動力至各驅(qū)動橋，兼作副變速器之用。常設兩個檔，低檔又稱加力檔。為了不使后橋超載常設有連鎖機構(gòu)，使只有接合

18、前驅(qū)動橋以后才能掛上加力檔，并用于克服汽車在壞路面上和無路地區(qū)的較大行駛阻力及獲得最低穩(wěn)定車速。高檔為直接檔或者亦為減速檔。越野汽車在良好道路行駛時，為減小功率消耗及傳動系機件和輪胎磨損，一般要切斷通前橋動力。在越野行駛時，根據(jù)需要接合前橋并采用低速檔，增加驅(qū)動輪數(shù)和驅(qū)動力。分動器按結(jié)構(gòu)可以分為帶軸間差速器的分動器、不帶軸間差速器的分動器和裝有超越離合器的分動器。（1）帶有軸間差速器的分動器，各輸出軸可以以不同的轉(zhuǎn)速旋轉(zhuǎn)，而轉(zhuǎn)矩分配則由差速器傳動比決定。據(jù)此，可將轉(zhuǎn)矩按軸荷分配等比例地分配到各驅(qū)動橋。裝用這種分動器的汽車，不僅掛加力檔時可使全輪驅(qū)動，以克服壞路面和無路地區(qū)地面的較大阻力，而且掛分動器高當時也可使全輪驅(qū)動，以充分利用附著重量及附著力，提高汽車在好路面上的牽引性能。（2）不帶軸間差速器的分動器，各輸出軸具有相同的轉(zhuǎn)速，而轉(zhuǎn)矩分配則與該驅(qū)動輪的阻力及其傳動機構(gòu)的剛度有關。這種結(jié)構(gòu)的分動器在掛低檔時同時將接通前橋驅(qū)動橋；而掛高檔時前橋驅(qū)動橋則一定與傳動系分
