Abstract
The invention discloses an oil seal lubricating structure of a hydrodynamic retarder. When the hydrodynamic retarder does not work, a transmission shaft synchronously rotates along with an input shaft of an automobile gearbox. In this way, the transmission shaft drives an oil suction element to work, oil in an oil storage cavity is delivered into a second work oil cavity by the oil suction element, and at the same time, the transmission shaft drives a rotor impeller to synchronously rotate. When the rotor impeller rotates, air current is produced. Air current flows into the second work oil cavity via a through hole in the rotor impeller, oil in the second work oil cavity is pressed into an axial blind hole through air current, and oil flowing into the axial blind hole flows into a clearance between an oil seal structure and an expansion ring seal structure via a radial through hole. The oil seal lubricating structure can lubricate an oil seal between the transmission shaft and an end cover.
