Description
Summary: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.
