黑龙江省交通科研所研制成功用于汽车润滑的H-1型节能减磨剂,经过哈尔滨市汽车运输一场、二场、七场和吉林第五货运公司试用,表明其技术经济效益显著,具有推广价值。目前,载重汽车后桥的螺旋伞齿轮和变速箱齿轮大都使用渣油型齿轮油,即二十号(冬用)或三十号(夏用)普通齿轮油来进行润滑。由于这种油粘度大,低温流动性差,冬季汽车起步很困难,“挂挡”也费力,有人采用 Traffic Research Institute of Heilongjiang Province successfully developed for automobile lubrication H-1 energy-saving anti-wear agent, after a Harbin automobile transport, two, seven and Jilin fifth freight company trial, indicating significant technical and economic benefits, with Promote value. At present, most of the helical bevel gears and gearbox gears of the rear axle of the truck are lubricated by the residue type gear oil, that is, ordinary gear oil on the 20th (winter) or on the 30th (in summer). Because of this oil viscosity, low temperature fluidity is poor, very difficult to start the winter car, “hanging block” is also laborious, it was used
