A motor
train unit foundation
brake device suitable for a high and cold environment comprises a clamp
forceps unit, a
brake disc and a
brake lining and is characterized in that double-side gaps between the brake disc and the
brake lining are increased to be 3-6mm, gaps among friction particles in the
brake lining are not smaller than 6mm, the friction particles on the
brake lining are oval, the directions of gaps among the friction particles are arc-shaped, and an anti-freezing
coating is sprayed on the surfaces of the clamp
forceps unit and a brake cylinder. The motor
train unit foundation brake device ensures that
grinding materials produced in the braking process in
extreme weather or hard particles from the outside can be smoothly discharged, the production origin of
metal inserts is eliminated, and a phenomenon that the brake disc and the brake lining are possibly engaged unfirm. In addition, the shortcoming of unsmooth discharging
impurity of an original brake disc is overcome, the discharging of the
grinding materials produced in the braking process or the hard particles from the outside is facilitated, the production origin of
metal inserts is further eliminated, an abnormal abrasion phenomenon of the brake disc is effectively decreased, the maintenance working amount and the maintenance cost are reduced, and the vehicle
utilization rate is improved. The anti-freezing
varnish is spayed on the surfaces of the clamp
forceps unit and the brake cylinder, and
snow and ice are prevented from being accumulated.
