The invention provides an automobile retarder. The automobile retarder comprises a power transmission shaft, a driving disc, a driven disc, a cylinder, a hydraulic pump, an oil supply pipe, engine oil, a shell, bearings and a shaft sealing device, wherein the power transmission shaft is connected with the driving disc, the driven disc is in sliding connection with the shell, the cylinder is mounted on the driven disc, one side of an oil port of the oil supply pipe is connected with the hydraulic pump, the other side of the oil port of the oil supply pipe is arranged between oil films formed bycontact surfaces of the driving disc and the driven disc through the driven disc, the bearing is fixedly connected with the power transmission shaft and movably connected with the shell, and a shaftsealing device is installed at the joint. When relative rotation occurs under the condition that the hydraulic pressure of an oil film between the contact surfaces of the driving disc and the driven disc is greater than or equal to the pressure between the contact surfaces of the driving disc and the driven disc, the oil film structure between the contact surfaces of the oil film structure changescontinuously, force opposite to the rotating direction of the power transmission shaft can be generated, the retarding effect of the automobile retarder is achieved, and the oil film structure is aninnovative design.

    本发明提供一种汽车缓速器,包括动力传动轴、主动盘、从动盘、气缸、液压泵、供油管、机油、壳体、轴承、轴密封装置,动力传动轴和主动盘连接,从动盘和壳体滑动连接,气缸安装在从动盘上,供油管油口的一侧连接液压泵,供油管油口的另一侧通过从动盘安装在主动盘和从动盘接触面形成的油膜之间,轴承与动力传动轴固定连接与壳体活动连接并在连接处安装轴密封装置,在主动盘和从动盘接触面间的油膜的液压大于或等于主动盘和从动盘接触面之间的压强情况下发生相对转动时,其接触面之间油膜结构不断发生变化,能产生一个和动力传动轴转动方向相反的力,起到汽车缓速器的缓速作用,是一个比较有创新的设计。
