Abstract
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.
Description
Technical field
The present invention relates to rail vehicle brake rigging, especially relate to the brake rigging that EMU under a kind of psychro-environment avoids occurring brake disc abnormal wear.
Background technique
When EMU is runed at ice and snow weather, the ice and snow that extremely low ambient temperature and rail motor set high speed operation are rolled causes brake rigging accumulated ice accumulated snow serious, thereby the accumulated ice accumulated snow especially on brake lining causes brake lining and brake disc actual gap to diminish, occurs the empty phenomenon of embracing of brake lining; Simultaneously on brake lining, friction particles is regular hexagon and gap is little, and the metal removal thing producing in braking process and the hard particles coming from the outside cannot be discharged in time, form the nucleus of damascene or participate in grinding brake disc directly, thereby causing brake disc abnormal wear.
At present, similar measure has all been taked in the countries in the world especially country of extremely frigid zones (mainly comprising Northern Europe, Russia, Japan etc.), is mainly the frequency of utilization of ice-melt snow removing, fall-back, minimizing ice and snow weather rail motor set.Be below Northern Europe (Sweden), Russia, measure that Japanese winter, vehicle was taked:
(1) Northern Europe (Sweden) ice-melt snow removing measure
Circuit snow removing, for ice and snow weather in winter, is mainly carried out in Northern Europe, is equipped with special snow removing locomotive, and the Snowremoval on roadbed is arrived to roadside.Meanwhile, on circuit, be equipped with ice-melt snow cleaner, use the propylene glycol of heating to carry out deicing to brake rigging.
(2) Russian ice-melt snow removing measure
When ice and snow weather is serious, in storehouse, be equipped with hot water ice-melt snow cleaner, use low pressure hot water to carry out deicing to brake rigging.
(3) Japanese ice-melt snow removing measure
When ice and snow weather is serious, on circuit, be equipped with hot water ice-melt snow cleaner, use hot water to carry out deicing.
In sum, the brake disc abnormal wear problem that the icing accumulated snow of basic brake device of motor train set causes is global problem, main by the exterior measures reply ice and snow weather such as snow removing, outfit ice-melt snow removing equipment or employing speed limits (containing stopping transport), these schemes need a large amount of human and material resources, financial resources, increase repair and maintenance workload and operation cost.
Summary of the invention
The object of the invention is to solve problem from brake rigging inside, thereby providing a kind of can either use under general environmental conditions, the braking device of brake disc abnormal wear be can avoid occurring at extremely frigid zones Snowfall again, repair and maintenance workload and operation cost reduced.
For achieving the above object, the invention provides a kind of basic brake device of motor train set being applicable under psychro-environment, comprise nipper units, brake disc, brake lining, it is characterized in that: the bilateral gap between brake disc and brake lining is increased to 3～6mm, gap in brake lining between each friction particles is 6～8mm, on brake lining, friction particles is shaped as ellipse, gap direction between friction particles is arc, identical with brake disc sense of rotation, at surface spraying one deck anti-icing coatings of nipper units and master cylinder.
Described anti-icing coatings is the SF 90-0000/0 freezing varnish of bright Ke Weize.
The present invention is increased to 3-6mm by gap on the basis in gap between former brake disc and brake lining, the grinding thing producing in braking process under assurance extreme weather or the hard particles coming from the outside can be discharged smoothly, eliminate the root that damascene produces, and avoid brake disc and brake lining empty phenomenon of embracing to occur, adopt the brake lining of the large gap structure of friction particles simultaneously, gap 6～8mm in brake lining between each friction particles, on brake lining, friction particles is shaped as ellipse, and the position of friction particles is rearranged, making the gap direction between friction particles is arc, identical with brake disc sense of rotation, changed the not smooth shortcoming of former brake lining chip removal, be convenient to the grinding thing producing in braking process and the hard particles coming from the outside to discharge, further eliminated the root of damascene, effectively reduced brake disc abnormal wear phenomenon, reduce repair and maintenance workload and maintenance cost, improve vehicle utilization ratio, at nipper units and master cylinder surface spraying one deck freezing varnish, prevent surperficial accumulated snow accumulated ice.
