  七、常見故障分析及排除Common Malfunction Analysis and Solution1、車輛在行駛中,驅動橋發響的判斷和排除。Analysisand Solution on Driving Axle Noises during Running

水蜜桃成视频人app下载   ? ??該驅動橋為帶輪邊減速的驅動橋,行駛中,中、后橋發響,一般是以下原因造成的:The driving axle is equipped with hub reductiongear, during running, middle and rear axle make noises, mostly because:

  1)驅動橋齒輪的間隙過小或過大。Tooth gap of driving axle is over small or big.

  2)主、從動齒輪裝配不當。Driving and driven gear is installed improperly.

水蜜桃成视频人app下载   3)齒輪軸承調整不當,及軸承座孔磨損后重新裝配不同心。When gear bearing is adjusted improperly andbearing base hole is worn, decentraction happens during reassembling.

水蜜桃成视频人app下载   4)輪邊減速器行星齒輪和內齒圈間隙由于磨損增大,換新后安裝不當。Clearance between hub reduction gear planet gearand inner ring is over big for wearing, and reinstalled improperly.

  5)太陽輪和半軸花鍵磨損、間隙變大。Sun gear and semi-shaft key are worn andclearance is big.

  6)驅動橋殼彎曲變形。Driving axle housing is bent and deformed.

  判斷及排除辦法Solution

水蜜桃成视频人app下载   1)行駛中如果中、后驅動橋出現連續的聲響,用手摸驅動,如果有發熱現象,可能是缺少潤滑油,應檢查油平面,少應添加。When middle and rear driving axle makecontinuous noises during running, if driving axle is hot felt by hands, it maybe lack of lubricant. Check oil level and add if lack.?

  2)如果行駛中出現有節奏的撞擊聲,一般是由于齒輪的齒隙過大,如果響聲過大應拆檢減速器,檢查齒輪磨損情況,如磨損嚴重應更換。The cadent impact sound during running may becaused by over big clearance of gear. If the sound is too big, remove reductiongear to check. Change if worn seriously.

  3)如果行駛中,響聲隨車速的提高而加強,滑行時聲音減少或消失,多半是軸承磨損和齒隙不當所致,應當更換軸承,調整齒隙。When noises become stronger as increased speedduring running and become weaker or disappeared during sliding, it may becaused by worn bearing and improper clearance, change bearing and adjustclearance.

  4)車輛在轉彎行駛中,驅動橋出現響聲,多半是差速器行星齒輪齒隙過大,或半軸齒輪鍵槽和半軸齒磨損過甚,應拆卸更換差速器行星齒輪,半軸齒輪。Noises from driving axle during turning may becaused by over big clearance of differential mechanism planet gear or by overworn semi-shaft gear key groove and semi-shaft tooth, remove and changedifferential mechanism planet gear and semi-shaft gear.

  5)如果行駛中突然發生異常的響聲,多數是齒輪打壞,軸承散架。Sudden abnormal noises during driving may bethat gear is broken and bearing is fallen apart.

  6)輪邊減速器行星齒輪和內齒圈嚙合間隙大,也會出現隨車速提高而增強的異響,應更換輪邊減速器的齒輪及內齒圈。Over clearance between hub reduction planet gearand inner annular gear results in stronger abnormal noises as increased speed,change gear of hub reduction gear and inner annular.

  2、中橋橋間差速器損壞分析Analysison Damaged Differential Mechanism of Middle Axle

水蜜桃成视频人app下载   橋間差速器(軸間差速器)是保證中、后橋傳動差速運動的部件,橋間差速器和輪間差速器配合,中、后橋任意一個輪空轉,其它三個輪便不會受力旋轉,車輛不能行駛,不會發生單橋驅動全車載荷現象。Axle differential mechanism (shaft differentialmechanism) makes sure middle and rear axle transmission differential movement.Since axle differential mechanism works with wheel differential mechanism, whenany one wheel of middle and rear axle runs idly, the other three wheels willrun without suffering force and vehicle can’t run, thus it won’t happen that single axle drives theentire vehicle.

  如果橋間差速器失效,中、后橋傳動軸變為剛性連接,會在運行中導致一系列的故障發生。Whenaxle differential mechanism doesn’t work, connection between middle and rear axle transmission shaftis rigid and a series of problems may happen during running.

水蜜桃成视频人app下载   車輛轉彎時,中、后橋車輪滾過距離是不一致的,由于橋間差速失效,不能再差速旋轉,會造成輪胎拖滑,驅動橋內減速齒輪增加了附加載荷,齒輪的輪齒極易疲勞,斷裂。The distances that wheels of middle and rearaxle runs are the same during turning. Since axle differential mechanism doesn’t work and can’t turn differentially, which makes tireslide and driving axle inner reduction gear increases additional load, further,gear tooth is easy to get tired and broken.

  當車輛陷入泥濘中,如果一個輪空轉,掛上輪間差速鎖,則整個車的負荷集中到一根驅動橋上,負荷過大,單個驅動橋難以承受,會導致減速器齒輪的打壞、折斷。When vehicle traps into mud and one wheel runsidly, if hangs wheel differential lock, the whole vehicle load focuses on onedriving axle. With over load, single driving axle is hard to suffer and resultin reduction gear broken.

水蜜桃成视频人app下载   橋間差速器是不可缺少的部件,使用中出現故障主要是行星齒輪、軸承的損壞,其損壞原因是潤滑不良。橋間差速器位于中橋的最前端,主要是靠中橋減速器齒輪飛濺油進行潤滑,由于橋間差速器距離遠,車在低速運行時飛濺的油較少,潤滑條件差,造成橋間差速器的損壞。而特別是油位低時更容易導致橋間差速器的故障。

  Axledifferential mechanism is necessary and most problem is damaged planet gear andbearing, which is mainly because poor lubrication. Axle differential mechanismis in the front of middle axle, which is mainly lubricated by splashed oil frommiddle axle reduction mechanism gear. Since distance of axle differentialmechanism is far and there is less splashed oil during low speed running, poorlubrication results in axle differential mechanism damaged. Especially when oillevel is low, it is easier to make axle differential mechanism problem.

  使用中應注意以下幾點:Attentions during usage:

  1)驅動橋必須保證有足夠的潤滑油,應經常檢查中、后橋的油面,不足的應及時添加,并注意向過橋箱中加油。Make sure enough lubricant in driving axle andcheck oil level of middle and rear axle frequently, add if necessary.

  ?2)每次二級保養均應檢查油面、油質、對變質的油應予以更換。Check oil level and quality in everysecond-class maintenance and change degenerative oil.

水蜜桃成视频人app下载   ?3)每次二級保養均應對橋間差速器進行性能試驗,試驗方法是:懸起中、后橋任一車輪,起動發動機使該輪旋轉,橋間差速器應差速旋轉,如果該輪不能順利旋轉,或橋間差速器內有雜音,均應進行拆卸檢修。Test performance of axle differential mechanismin every second-class maintenance. Test procedure is: raise any one wheel ofmiddle and rear axle, start engine to make the wheel rotate, if the wheel can’t rotate smoothly or there is noise from axle differentialmechanism, remove and check.

  4)正確使用差速鎖。當車輪打滑旋轉,路面平坦,阻力不太大,又可以直線行駛時,可以使用橋間差速鎖。當車輪打滑懸空時,嚴禁使用橋間差速鎖,應找車牽引。Use differential lock correctly. When wheel slipson flat road with not big resistance but runs straightly, differential lock canbe applied. When wheel slips in the air, mustn’t use axle differential lock, instead dragged by othervehicle.?

  3、中、后驅動橋差速器打壞的原因分析:Analysison Damaged Differential Mechanism of Middle and Rear Driving Axle

水蜜桃成视频人app下载   1)掛上軸間、輪間差速鎖后,轉動方向盤打壞差速器。掛上差速鎖后,差速鎖不再起分速差動作用,打方向盤轉彎極易造成差速器損壞。After differential locks of axles and wheels areconnected, turning steering wheel breaks differential mechanism. Afterdifferential locks are connected, differential mechanism doesn’t work, at the time turning steering wheel makes it easy to breakdifferential mechanism.

  2)差速鎖開關損壞。掛上差速鎖,沖出不良路面后,應關掉差速鎖開關。由于電器方面的原因,蹺板開關故障,差速鎖沒有摘掉,打方向盤轉彎造成差速器打壞。Differential lock switch is broken. Afterdifferential lock is connected and runs out of poor road, switch offdifferential lock switch. For the reason of electric appliance, rocker switchhas problem and differential lock is still connected, thus turning steeringwheel breaks differential mechanism.

  ?3)未在車輛處于停止狀態下掛上差速鎖。車輛還在運行中,掛上差速鎖,由于扭力過大,打壞差速鎖。Differential lock isn’t connected when vehicle stops. When vehicle is still running,connect differential lock and break differential lock for over big torque.

  注意:打壞差速器的根本原因是操作問題,提醒用戶注意:掛上輪間差速鎖以后千萬不能打方向,要直線行駛。

  Attention: the key reason to breakdifferential mechanism is operation problem. Attention: mustn’t turn steering wheel after connect wheel differential lock andrun straightly.

水蜜桃成视频人app下载   4、中、后驅動橋差速鎖的正確使用、注意事項及檢查方法Operation, Attentions and Check on Differential Lock of Middle and RearDriving Axle

  1)在車輛通過泥濘或不良路面要使用軸間差速鎖時,最好在車輛處于停止狀態(或相當于步行速度,但最好是在停止狀態),通過駕駛室內的軸間差速鎖蹺板開關操作,是由電控氣動閥來控制的,在接合差速鎖時,必須先分離離合器,當軸間差速鎖接合時,蹺板開關下指示燈亮。When vehicle runs over muddy or poor road with axle differential lock,better park vehicle(or at the speed of walking, while better on the conditionof parking),operate byrocker switch of axle differential lock in the cab and controlled by electronicpneumatic valve, at the time of connecting differential lock, must separateclutch. When connect axle differential lock, low indicator of rocker switch ison.

  如果有輪間差速鎖,裝在主減速器殼體內側。輪間差速鎖和軸間差速鎖的結構大體上相同。在它處于接合位置時,一根半軸被鎖到差速器殼體上,使差速器不起作用,即兩根半軸,以同樣的轉速同方向旋轉。應注意的是:輪間差速鎖,只有在車輛直線行駛時才能使用。在車輛處于停止狀態下,或者是相當于步行的速度下通過駕駛室內輪間差速鎖蹺板開關操縱。也須在接合之前先分離離合器。應該強調的是:當車輛通過泥濘或不良路面,去掉輪間差速鎖后,指示燈繼續亮,車輛絕對不能轉彎行駛,應停車查明原因,直到真正地摘掉輪間差速鎖后,車輛才能轉彎行駛,以免打壞差速器齒輪。Wheel differential lock is installed inside ofmain reduction gear case if any. The structure of wheel differential lock isalmost same with axle differential lock. When it is connected, one semi shaftis locked differential mechanism housing which makes differential lock notwork, that is two semi shafts run at the same time in the same direction. Attentions:wheel differential lock can be only used when vehicle runs straightly. Whenvehicle stops or runs at the speed of walking, it operates through wheeldifferential lock rocker switch in the cab and separates clutch beforeconnecting. Specially emphasize: when vehicle runs on muddy poor road, afterdisconnect wheel differential lock, indicator keeps on, vehicle mustn’t turn instead to check until completely disconnect differentiallock, in case to break differential mechanism gear.

  如果路況實在不好,需將軸間差速鎖和輪間差速鎖同時使用時,應先接合軸間差速鎖,再接合輪間差速鎖。接合之前均應先分離離合器。應注意接合輪間差速鎖后,車輛不能轉彎行駛。If road is terribly poor, it should use wheel and axle differentiallock at the same time. Connect shaft differential lock first and then connectaxle differential lock, which is done before separating clutch. Pay attention:after connect wheel differential lock, vehicle can’t make a turn.

  2)使用差速鎖應注意事項:Attentions when use differential lock

  A:接合軸間或輪間差速鎖,必須先分離離合器,在車輛處于停止狀態下(或相當于步行速度行駛),通過蹺板開關操作,接合后指示燈應亮。Connect axle or wheel differential lock after separate clutch. Whenvehicle stops (or runs at walking speed), it operates by rocker switch andindicator is on after connecting.

  ?B:使用輪間差速鎖,車輛只能直線行駛,不允許轉彎,轉彎會打壞齒輪。When wheel differential lock is applied, vehicle can only runstraightly instead of turning otherwise gear may be broken.

  C:如果摘掉輪間差速鎖,指示燈仍亮,車輛還是不能轉彎,應停下查明原因,直到真正去掉輪間差速倘后,才允許轉彎行駛。

  When remove wheel differential lock, indicator is onand vehicle still can’t turn, should find out the reason until wheel differential lock is removedcompletely, then vehicle can run and make turn.

  ?D:通過不良路面后,應去掉軸間差速鎖,如指示燈還亮,應查明原因,確定已摘掉了軸間差速鎖,如果不摘掉軸間差速鎖,汽車行駛阻力大,速度提不起來,油耗增加。When vehicle runs on poor road, it should remove shaft differentialaxle, if indicator is still on, find out reason until make sure axledifferential lock is removed. If axle differential lock isn’t removed, vehicle speedcan’tincrease with big resistance, which will increase oil consumption.

  ?E:檢查軸間差速鎖和輪間差速鎖的方法Check axleand wheel differential lock

水蜜桃成视频人app下载   為了確保車輛有良好的通過性能,應定期對軸間差速鎖和輪間差速鎖的接合性能進行檢查,做法是:每運行12000Km進行二級保養時,全面檢查。

  For better performance, check connection of axle andwheel differential lock regularly. That is: check thoroughly duringsecond-class maintenance every 12000Km.

水蜜桃成视频人app下载   ?3)檢查方法Check

  ?A:將車輛停放在平坦、寬闊處,頂起車輛一側驅動軸車輪(6×4頂起中、后;6×6頂起前、中、后;4×4頂起前、后;4×2頂起后),松開手制動閥,變速器在空檔位置,用手轉動頂起一側的車輪,應能轉動自如,如果轉不動,說明差速鎖在鎖止狀態。Vehicle parks on flat and wide place, lift driving axle wheel one side(6×4 lift middle and rear, 6×6 lift front, middle and rear, 4×4 liftfront and rear, 4×2 lift rear)

水蜜桃成视频人app下载   ?B:在蹺板開關、指示燈、線路、氣路均正常的情況下,打開電源開關,指示燈應不亮。否則說明差速鎖處在鎖止狀態,應進行檢查,排除。When rocker switch, indictor, circuit and gas line works, open powerswitch and indicator isn’t on. Otherwise it means differential lock is locked, should check.

水蜜桃成视频人app下载   ?C:起動發動機,氣壓達到0.7Mpa,按動蹺板開關,分別掛上前、中、后輪間差速鎖,轉動頂起一側的車輪,若轉不動,說明處在鎖止狀態,否則差速鎖沒有掛上,應查明問題,并排除。Start engine with air pressure 0.7Mpa, press rocker switch, connect front,middle and rear wheel differential lock, turn and lift wheel one side. If thewheel can’t turn, it is locked, otherwise differential lock isn’t connected, should findout problem and solve.

  ?D:起動發動機,氣壓達到0.7Mpa,掛上軸間差速鎖,轉動頂起一側的車輪,中、后驅動車輛應以同一速度旋轉,說明軸間差速鎖在鎖止狀態。Start engine with air pressure 0.7Mpa, connect axledifferential lock, turn and lift wheel one side, middle and rear driving axleshould runs at the same speed, which means axle differential lock is locked.

水蜜桃成视频人app下载   E:在按動蹺板開關后,指示燈應亮,如不亮且軸間和輪間差速鎖已真正掛上,應查明電路故障。After press rocker switch, indicator is on. If not and axle andwheel differential lock are connected, should check circuit.

  ?5、中、后驅動橋輪邊減速器零件修復及更換Repair and Changeof Hub Reduction Gear Parts of Middle and Rear Driving Axle

水蜜桃成视频人app下载   ?? ??當輪邊行星齒輪減速器有下列缺陷時,應予以修復或更換。

  When hub planet gear reduction has below problems,should repair or change.

  ?1)行星齒輪、內齒圈、太陽輪的輪齒工作表面嚴重磨損或輪齒折斷。

水蜜桃成视频人app下载   Working surface of planet gear, annular gear and sunwheel is worn seriously or broken.

  ?2)行星齒輪軸軸頸及行星齒輪內孔和滾針軸承的配合表面有嚴重的磨損痕跡。

  Matching surface of bore and roller bearing of planetgear shaft journal and planet gear is worn

  3)太陽輪齒輪花鍵孔和半軸花鍵磨損側隙超0.6mm。

  Sun wheel gear splined hole and semi shaft spline isworn over 0.6mm.

  4)齒圈、花鍵孔和軸頭花鍵磨損,側隙超過0.8mm。Gearring, splined hole and spindle nose spline is worn over 0.8mm.

  5)行星齒輪內、外推力墊圈劃傷或者有嚴重的磨損痕跡。Planetgear inner and outer thrust washer is scratched or worn seriously.

  6)太陽輪內、外推力墊圈劃傷或者有嚴重的磨損痕跡。Sunwheel inner and outer thrust washer is scratched or worn seriously.

  6、制動鼓維修注意事項Attentions onRepair of Brake Drum

水蜜桃成视频人app下载   制動鼓在使用中因為磨損而使內徑增大,并會產生失圓、錐度,導致和輪轂不同心。當制動鼓的內表面錐度過大時 ,將使制動磨擦片和制動鼓的貼合面積減少,制動效能降低。當制動鼓失圓和輪轂不同心時,會造成制動蹄片和制動鼓接觸不平穩,制動時會產生振動,并導致制動效能的降低。

水蜜桃成视频人app下载   Bore of brake drum increases owing to wearingtogether with out of round and taper, which results in decentraction with hub.Increasing taper on the inner surface of brake drum makes fitting area of brakefriction disc and brake drum decrease and lower brake performance. Out of roundbrake drum and decentraction with hub makes brake shoe and brake drum contactunsteadily and vibration occurs during braking, which results in low brakeperformance.

水蜜桃成视频人app下载   制動鼓在出現上述情況時,應拆卸檢修。檢修時,內徑的磨損、失圓、錐度應用大號游標卡尺測量。在同一斷面徑向測量的最大和最小差值為失園,在軸線方向測量的最大和最小差值為錐度。制動鼓和輪轂的不同心度是以輪轂和軸承為基準,用帶支架的千分表測量的。不同心度不能大于0.25mm。若制動鼓的錐度大于0.1mm,失園度大于0.2mm,不同心度大于0.25mm,且制動鼓的工作面又有深的溝槽時,應對制動鼓進行鏜銷加工。制動鼓的內徑為500mm,由于鏜削、磨損,內徑會變大,剛度為之降低,制動時會產生彈性變形,致使制動蹄片的壓緊力減少,制動效率降低。因此,制動鼓的內徑不能大于504mm,如果鏜削后制動鼓內徑超過504mm,不能再繼續使。
