    自動攪拌車出現抖動是因為什么?

    如果混凝土攪拌車在行車過程中,發現車身有輕微的抖動或偏移,一般是輪胎引起的故障。首先可能是輪胎平衡狀況不佳,需要車主盡快去做一個四輪定位和動平衡,如果車輛不跑偏做一下輪胎動平衡即可。
    If the body of the concrete mixer truck vibrates or deviates slightly during driving, it is generally caused by the tire. First of all, the tire balance may be poor. The owner needs to do a four-wheel alignment and dynamic balance as soon as possible. If the vehicle does not deviate, do a tire dynamic balance.
    另外一種狀況則較為嚴重,可能是因為鋼圈變形所致,這就需要車主去專業的維修店檢查。這種狀況一般發生在使用年限較長的水泥攪拌車身上。一般攪拌車更換新輪胎、新鋼圈時都要做一次輪胎平衡,否則配重不平均時方向盤就容易發生抖動的現象。車身抖動對行車舒適感和操控判斷都會有所影響。
    The other condition is more serious, which may be caused by the deformation of the steel ring, which requires the owner to go to a professional maintenance shop for inspection. This situation generally occurs on the cement mixing vehicle body with long service life. Generally, when replacing new tires and steel rings for mixer trucks, tire balance should be done once, otherwise the steering wheel is prone to shake when the counterweight is uneven. Body shake will affect driving comfort and handling judgment.
    第三種情況是因為攪拌車傳動軸變形不平衡引起,一般這種情況出現在底盤碰撞過的車比較多。
    The third situation is caused by the unbalanced deformation of the transmission shaft of the mixer truck. Generally, this situation occurs in more vehicles with chassis collision.
    攪拌車怠速時的車身抖動
    Body shaking of mixer truck at idle speed
    怠速車身抖動是很多攪拌成司機常遇到的狀況。如果司機在啟動攪拌車或將攪拌車停駛未關閉發動機情況下,如果發現車身抖動明顯,那么可能意味著攪拌車存在下面四種狀況:
    Idling body shaking is a common condition for many drivers. If the driver finds obvious body shaking when starting the mixer or stopping the mixer without turning off the engine, it may mean that the mixer has the following four conditions:
    1.攪拌車發動機積碳嚴重
    1. Serious carbon deposition of mixer engine
    造成混凝土攪拌車抖動最常見的原因就是節氣門過臟或噴油嘴積炭過多。當發動機內部的積碳過多時,冷啟動噴油頭噴出的汽油會被積碳大量吸收,導致冷啟動的混合氣過稀,使得啟動困難,這種狀況下,只有等到積碳吸收的汽油飽和,才容易著車,著車后吸附在積碳上的汽油又會被攪拌車發動機的真空吸力吸入汽缸內燃燒,又使混合氣變濃,攪拌車發動機的可燃混合氣時稀時濃,造成冷啟動后怠速抖動。氣溫越低,冷啟動所需要的油量越大,積碳的存在就越會影響冷啟動的順利與否。
    The most common reason for the shaking of concrete mixer truck is that the throttle is too dirty or the fuel injection nozzle has too much carbon deposition. When there is too much carbon deposit inside the engine, the gasoline ejected from the cold start fuel injection head will be absorbed by the carbon deposit, resulting in too thin cold start mixture, which makes it difficult to start. In this case, it is easy to start the car only when the gasoline absorbed by the carbon deposit is saturated. The gasoline adsorbed on the carbon deposit after landing will be sucked into the cylinder for combustion by the vacuum suction of the mixer engine, It also thickens the mixture, and the combustible mixture of the mixer engine is thin and thick, resulting in idle jitter after cold start. The lower the temperature, the greater the amount of oil required for cold start, and the existence of carbon deposition will affect the smooth cold start.
    解決辦法:清洗油路,檢查怠速馬達是否有積碳應該清洗。
    Solution: clean the oil circuit and check whether there is carbon deposit in the idle motor. It should be cleaned.
    2.攪拌車點火系統問題
    2. Ignition system of mixer truck
    檢查一下火花塞、高壓導線和點火線圈的工作狀況,點火系統工作不良,火花塞跳火狀況不好同樣會導致這類故障現象。
    Check the working conditions of spark plugs, high-voltage wires and ignition coils. Poor ignition system and poor spark plug jumping will also lead to such faults.
    解決辦法:檢查火花塞是否積碳過多,更換火花塞。
    Solution: check whether the spark plug has excessive carbon deposit and replace the spark plug.
    3.攪拌車油壓不穩
    3. Unstable oil pressure of mixer truck
    如果已經清理過發動機積碳、洗過節氣門、換過油墊以及火花塞等,仍然發現怠速時車身抖動,建議您到修配廠檢查燃油供油壓力以及進氣壓力傳感器等是否正常,如果油泵供油壓力不正?;蜻M氣壓力傳感器數值錯誤和工作不良都會引發車身抖動。
    If you have cleaned the engine carbon deposit, washed the throttle valve, changed the oil pad and spark plug, and still find the body shaking at idle speed, it is recommended that you go to the repair shop to check whether the fuel supply pressure and intake pressure sensor are normal. If the fuel supply pressure of the oil pump is abnormal or the value of the intake pressure sensor is wrong and works poorly, the body shaking will be caused.
    解決辦法:檢查油壓,必要時更換部件。
    Solution: check the oil pressure and replace the parts if necessary.
    4、攪拌車發動機部件老化
    4. Aging of engine parts of mixer truck
    自動攪拌車抖動還與引擎腳(又稱機爪墊)老化有關。引擎腳其實是攪拌車發動機的避震系統,引擎腳負責吸收發動機在運轉時候的細微抖動,如果引擎腳出現問題,這些震動就會傳到方向盤、駕駛室內,造成怠速時發生抖動。
    The shaking of automatic mixer truck is also related to the aging of engine foot (also known as machine claw pad). The engine foot is actually the shock absorber system of the mixer engine. The engine foot is responsible for absorbing the slight jitter of the engine during operation. If there is a problem with the engine foot, these vibrations will be transmitted to the steering wheel and cab, resulting in jitter at idle speed.
    解決辦法:更換部件。
    Solution: replace the parts.
