Transmission Oil Supply
由来自变速箱泵的机油供应并控制动力传动系的大量重要部件。 系统中的压力通过变速箱液压控制安全阀调节。 该阀具备调节系统压力和向变矩器供应正确油压的双重用途。
可能需要进行测试,以确定变速箱泵是否为系统中的每个部件都供应正确的油量。
可测试以下压力,以确定机油供应是否充足。
- 变速箱机油滤清器进口
- 变速箱液压控制安全阀
- 变矩器锁止离合器
- 行星齿轮变速箱离合器
- 变矩器进口安全压力
如果在变速箱液压控制系统中的任何地方测得机油压力不足,则应测试机油滤清器进口的机油压力。 请参考技术规格,系统操作/测试和调整, "液压油污染 - 测试"。 如果机油滤清器进口的压力在技术规格内,则应测试变速箱液压控制安全阀的压力。 请参考技术规格,系统操作/测试和调整, "安全阀(变速箱液压控制)- 测试和调整"。
如果变速箱液压控制安全阀的压力低于技术规格,则机油滤清器可能堵塞,并且机油滤清器旁通阀无法正常工作。 拆下机油滤清器旁通阀,并检查机油滤清器旁通阀是否磨损或损坏。
如果机油滤清器旁通阀的机油压力低于规定范围,则变速箱油泵损坏或破裂。 变速箱油泵不可维修,则必须更换。
