To further study wet multi-plate brake operating characteristic

by using contact temperature calculation model

thermal analysis fundamentals and Laminar flow equation

the theoretical modeling of the wet brakes brake torque

the surface temperature and the operating characteristic of towing torque are carried out.The influence regulation of the wet brake friction surfaces oil groove shape

lubricating coolant flow

the brake hydraulic pressure on brake working characteristic is studied.The results show that double circular oil groove with the processing simple compared to other oil groove

the brake torque is higher

the surface temperature is small

with a row of smaller towing effect

lubricating coolant flow primarily has a greater impact on wet brake response time

the greater the flow of brake response time is longer

lower the temperature of the braking surface in addition with the higher towing torque

the brake pressure on the braking torque of the brake torque is mainly reflected in the response time

the greater the pressure

the shorter the response time

the surface temperature is higher

and it has a limited discharge on the towing torque.
