Optimization Design of Low Drag Torque Parameters of High-speed Wet Clutches
Jixie chuandongIn order to reduce the drag torque under high speed conditions, the equivalent radius is introduced into the traditional low speed torque model of a wet clutch with track vehicle, and the calculation model of the drag torque with radial groove is derived.
