Structure of the newly developed hydro viscous soft start transmission is introduced and the hydroviscous braking model is presented. The study on the hydro viscous brake shows that a coupling relationship exists among the parameters of oil film thickness, hydro viscous torque and friction disc speed. The variation of hydro viscous torque is determined by the trend speeds to zero of friction disc speed and oil film thickness. When different patterns of oil film thickness are applied, hydro viscous torque and friction disc speed will have obviously distinct characteristics.
