攪拌車的底盤上的零部件也很多,減震器這個部件大家應(yīng)該都比較熟悉,減震器是用來抑彈簧吸振后反彈是的震蕩及來自路面的沖擊。在攪拌車的行駛過程中減震器一般都會有響聲,這是因為減震器與鋼板彈簧、車架或軸相互碰撞,膠墊損壞或是減震器防塵筒變形,油液缺乏等原因引起的,怎么判斷減震器是否良好呢?
There are also many parts on the chassis of the mixer truck. Everyone should be familiar with the shock absorber. The shock absorber is used to suppress the shock of the spring rebound after vibration absorption and the impact from the road. The shock absorber usually makes a noise when the mixer truck is running. This is caused by the collision between the shock absorber and the leaf spring, the frame or the shaft, the damage of the rubber pad, or the deformation of the shock absorber dust cylinder, the lack of oil. How can we judge whether the shock absorber is good?
如果攪拌車的減震器失效或者出現(xiàn)問題,應(yīng)查看減震器是否有漏油現(xiàn)象,用力按下保險杠,然后松開,假如攪拌車有兩到三次的騰躍,就說明減震器是好的。攪拌車在緩慢行駛中緊急制動,此時如果車輛的振動比較厲害,就說明減震器有問題,需要拆下減震器將其直立,并把下端銜接環(huán)夾在臺鉗上,用力拉壓減震桿數(shù)次,此時應(yīng)有穩(wěn)定的阻力,往上拉的阻力應(yīng)大于向下的阻力,如果阻力不穩(wěn)定或無阻力,可能是減震器內(nèi)部缺油或閥門零件損壞,應(yīng)終止修復(fù)或更換零件,并應(yīng)立即送去維修。
If the shock absorber of the mixer truck is invalid or has problems, first check whether the shock absorber has oil leakage, press the bumper firmly, and then release it. If the mixer truck jumps twice or three times, it means that the shock absorber is good. The mixer truck is under emergency braking during slow driving. At this time, if the vibration of the vehicle is severe, it indicates that there is a problem with the shock absorber. It is necessary to remove the shock absorber and put it upright, clamp the lower connecting ring on the bench vice, and pull and press the shock absorber rod several times. At this time, there should be stable resistance. The upward resistance should be greater than the downward resistance. If the resistance is unstable or no resistance, it may be the lack of oil in the shock absorber or the damage of valve parts, Repair or replacement of parts shall be terminated and sent for repair immediately.
攪拌車減震器漏油一般是以下幾個原因:
Oil leakage of mixer shock absorber is generally caused by the following reasons:
1. 減震器內(nèi)部的清潔度不夠好,有焊渣、鐵屑等雜物導(dǎo)致油封磨損。
1. the internal cleanliness of the shock absorber is not good enough. There are welding slag, iron filings and other sundries that cause the oil seal to wear.
2. 減震器的工作條件比較惡劣,外部的泥沙等雜物進入油封,導(dǎo)致其磨損漏油。
2. the working conditions of the shock absorber are relatively poor. The external sediment and other sundries enter the oil seal, resulting in wear and oil leakage.
3. 減震器油封的唇口老化,失去了密封的功能。
3. the lip of the shock absorber oil seal is aging and loses the sealing function.
4. 可能是在噴底盤裝甲的時候,減震器沒有遮擋好,裝甲附在減震器活塞桿上導(dǎo)致油封磨損而漏油。
4. it may be that the shock absorber was not well covered when spraying chassis armor, and the armor was attached to the piston rod of the shock absorber, resulting in oil leakage due to wear of the oil seal.
5. 控制活塞運動的支桿需要在金屬管的一端延長出來,所以這個部位一定能過要得密封嚴(yán)密,一般的漏油都和密封不嚴(yán)有直接關(guān)系的。
5. the supporting rod controlling the movement of the piston needs to be extended at one end of the metal pipe, so this part must be sealed tightly. Generally, oil leakage is directly related to the lax sealing.
6. 一般攪拌車的液壓的減震器漏油就說明它的使用年限已到。
6. oil leakage of hydraulic shock absorber of general mixer truck indicates that its service life has expired.
攪拌車底盤的減震器是非常重要的,很多人在做保養(yǎng)的時候都容易忽略它,希望看了這篇文章,大家能夠?qū)p震器引起重視。
The shock absorber of the mixer chassis is very important. Many people tend to ignore it when doing maintenance. I hope that after reading this article, everyone can pay attention to the shock absorber.
