Retarder for vehicles, especially heavy trucks

摘要

A continuous brake (retarder) for vehicles, especially for heavy trucks or the like, which utilizes a hydrodynamic circulatory system in the form of a driven hydrodynamic coupling whose operating fluid is conducted into an external circulatory system by way of a cooler or radiator; a separate cooler is coordinated to the hydrodynamic coupling which serves at the same time as feed pump for the operating fluid; additionally, the hydrodynamic coupling is operatively connected with a turbine in the external circulatory system which serves for the drive of a separate fan coordinated to the separate cooler.
