建德市桐廬縣殼牌液力傳動(dòng)油-渦輪機(jī)油經(jīng)銷液力傳動(dòng)油又稱自動(dòng)變速器油(ATF)或自動(dòng)傳動(dòng)油，用于由液力變矩器、液力偶合器和機(jī)械變速器構(gòu)成的車輛自動(dòng)變速器中作為工作介質(zhì)，借助液體的動(dòng)能起傳遞能量的作用1、粘度:以典型的液力傳動(dòng)油來看，使用溫度范圍約為-25℃~170℃，要求油品具有高的粘度指數(shù)和低的凝固點(diǎn)，一般規(guī)格規(guī)定粘度指數(shù)在170以上，傾點(diǎn)為-40℃，合成油為190℃與-50℃。 2、熱氧化安定性:汽車在行駛中液力傳動(dòng)油溫度隨汽車行駛條件的不同而不同。油溫升高氧化而生成的油泥、漆膜等會(huì)使液壓系統(tǒng)的工作不正常，潤(rùn)滑性能惡化，金屬發(fā)生腐蝕。 3、剪切安定性:液力傳動(dòng)油在液力變矩器中傳遞動(dòng)力時(shí)，會(huì)受到強(qiáng)烈的剪切力，使油中粘度指數(shù)改進(jìn)劑之類的高分子化合物斷裂，使油的粘度降低，油壓下降，最后導(dǎo)致離合器打滑。Automatic transmission fluid, also known as automatic transmission fluid (ATF) or automatic transmission fluid, is used as the working medium in automatic consisting of hydraulic torque converters, hydraulic couplings, and mechanical gearboxes. It plays a role in transmitting energy by using the kinetic energy of the liquid. 1. Vis: For typical automatic transmission fluid, the operating temperature range is about -25°C to 170°C. It is required that the oil has a high viscosity and a low pour point. Generally, the specifications stipulate that the viscosity index is above 170, the pour point is -40°C, and the synthetic is 190°C and -50°C. 2. Thermal oxidation stability: The temperature of the automatic transmission fluid in a car will vary different driving conditions. The formation of sludge and varnish due to the oxidation of the oil can cause the hydraulic system to operate abnormally, the lubricating performance toate, and the metal to corrode.
