Abstract
The utility model discloses an engineering machinery brake, relating to a brake apparatus and aims to provide a brake which has a long service life of a brake disc. In the technical scheme of the utility model, the brake comprises a brake flap, a main brake disc, an auxiliary disc, a driving shaft, a pressure plate and a handle; on a base in connection with the auxiliary brake disc along the circumference of a main shaft are uniformly distributed axial holes which are respectively in cooperation with columns; bolt threads are in cooperation with the threaded holes on a host housing and columns; the bolts between the right end face of each column and bolt pads are sleeved with an arc elastic cushion loop. The utility model is used for engineering truck brakes.
Description
Technical field:
The utility model relates to a kind of brake gear, particularly a kind of drg that is applicable to engineering truck.
Background technology:
The drg of existing engineering truck, form by axle drive shaft, handle, major and minor brake facing, base and column etc., this drg is after brake is finished, when after the release handle when starting locomotive, because the auxiliary brake sheet can not be thrown off the main frame brake disc simultaneously with the main brake sheet, rely on the pivoting friction of brake disc that it is unpluged, the every brake of locomotive once will rub once like this, makes its lost of life.
Summary of the invention:
The purpose of this utility model provides long drg of a kind of brake facing life-span.The technical solution of the utility model is, a kind of drg, comprise brake disc, main brake sheet, auxiliary brake sheet, axle drive shaft, pressing plate and handle, it is characterized in that: the base upper edge main shaft that is connected with the auxiliary brake sheet be evenly distributed in axial hole respectively with the column sliding fit, tapped bore on the screw thread of bolt and host shell and the column matches, a sheathed arc spring washer on the right side of each column and the bolt between the bolt pad.The utility model has the remarkable advantage of brake facing long service life compared with the prior art.
Description of drawings:
Accompanying drawing is the structural representation of the utility model drg.
The specific embodiment:
The utility model is in order to solve when main frame is restarted in the releasing brake, the auxiliary brake sheet can not be thrown off the scarce limit that brake disc and brake disc rub mutually automatically, the utility model is provided with an arc cushion 11 between the inner end surface of the end face of column 12 and bolt, this column have 4 be distributed on brake disc around.
Principle of work of the present utility model is, need be to the main frame glancing impact, hand-held handle 7 makes its rotation, drive axle drive shaft 4 and 3 rotations of main brake sheet, screw inclined plane on the right-hand member step surface of this axle drive shaft acts on down mutually being moved to the left until the main brake sheet with screw inclined plane on pressing plate 5 left sides and is adjacent on brake disc 2, continue to move handle, this moment, pressing plate 5 moved right along four columns 12 by cover plate 8, base 9, at this moment, arc cushion 11 deformation in compressions on the column, till auxiliary brake sheet 10 is adjacent to brake disc, finish the brake task.When stopping glancing impact, only need release handle, spring 6 resets makes that axle drive shaft moves to right, the main brake sheet is thrown off brake disc, meanwhile the arc cushion resets and makes auxiliary brake sheet on the base disengagement brake disc that moves to left, like this when main frame is starting, brake disc can not rub with the auxiliary brake sheet, thereby the drg life-span of the present utility model is longer.
