重型汽车变速器散热器简析

Brief Introduction of Radiator of Heavy-duty Truck Transmission

近年来,随着我国重型汽车的发展趋势,发动机功率不断提升,与之匹配的变速器输入转矩也越来越大,随之带来的问题是经常出现因为油温过高而使变速器工作失效;主要表现为机械直接损坏,如橡胶密封件的老化和同步器摩擦片的烧蚀等造成泄露、润滑不良、脱挡或卡挡。虽不像发动机对散热器散热功能要求那么高,

As the fast growth of domestic heavy-duty truck industry,power rate of engine is getting larger and larger in the past years,so that the outcome torque power of transmission also increase accordingly.It is unavoidable that transmissions have been damaged sooner than expected because of long-time operating of overheated oil.Nevertheless,radiator is urgently needed under certain operating conditions,and for some large-power-rate transmissions.
