FIELD: transport.SUBSTANCE: invention relates to railway vehicles. brake beam wearproof plate assembly for guide member of brake beam contains brake beam wearproof plate and brake beam guide member. The plate has grooved body with top wall and bottom wall connected by side wall and is made capable of tight entering the guide member of brake beam. Top wall of the plate has the first bead going sideways from the top wall. Bottom wall of the plate has the second bead going sideways from the bottom wall. The first bead of brake beam plate top wall contains locating tab going sideways from this bead and brake beam guide member with upper part and lower part. In the upper part of brake beam guide member, cut is made in which cut matched locating tab of brake beam plate can enter. In the first version, locating tab going from the first bead of brake beam plate top wall has semicircular form and its thickness is approximately equal to thickness of top wall first bead. In the second version, cut in the upper part of brake beam guide member has semicircular form. Locking unit of brake beam wearproof plate for guide member of brake beam contains brake beam wearproof plate and brake beam guide member. In the upper part of brake beam guide member, locking element going from it is made with which element the locking tab of brake beam plate can interact to prevent improper plate location in brake beam guide member. Locking tab going from the first bead of brake beam plate top wall has rectangular form and its thickness is approximately equal to thickness of top wall first bead.EFFECT: possibility to move brake beam without friction with side frame steel.6 cl, 5 dwg |
