The current trend of increasing the total weight and speed of vehicles, tougher requirements for road safety requires constant improvement of their braking systems. In this regard, for the main tractors and a number of other machines with a large operating weight is relevant to the use of brakes–retarders. This allows to increase the average speed, reduce the thermal stress of the main (working) brake mechanisms and increase their durability, which increases the level of active safety of vehicles. This article presents the results of studies of working processes in hydrodynamic brakes of retarders, determined the dependence of their braking efficiency on the design features. The studies were conducted using finite element models.
