For the problems of traditional heavy-duty engineering vehicle driven hydraulic or pneumatic disc brakes with braking pressure

sealing and other demanding

a new electromagnetic brake system is established

by introducing booster in the model

the internal pressure of the brake is reduced

a new heavy-duty engineering vehicle variation law of the electromagnetic brake key parameters of the model is studied and the brake disc of brake model in the braking process temperature field is analyzed.The results show that since the new electric brake to load as conditions classification criteria

in the course of the brake can be selected based on the actual needs of the applicable conditions to ensure the operability of the brake.With the increase of braking times

the overall temperature is a rising trend

the number of conditions under each brake model are no obvious local high temperature region

which has a positive significance reference to overcome the instability phenomenon heat mechanical.
