Abstract
The utility model relates to a kind of engineering machinery brake structures, including end block, pull rod, end block and pull rod pass through drag link mechanism and braking band connection, it further include main brake band and auxiliary braking band, the main brake band and auxiliary braking band discharge side by side, and main brake band tail end and auxiliary braking band tail end are rotatablely connected；The utility model beneficial effect is: side auxiliary braking band is connected with the tail end of main brake band makes brake force be evenly distributed.
Description
Technical field
The utility model relates to a kind of engineering machinery more particularly to a kind of engineering machinery brake structures.
Background technique
The common brake structure of the engineering machinery such as bull-dozer is mainly made of several parts once: end block, pull rod, braking metal
Band, brake lining；When brake band carries out braking maneuver, the side of brake band is resisted by end block, pull rod draws the another of brake band
Side.By reducing the diameter of brake band, increases brake lining and braking effect is reached to the pressure on revolving part surface.
The brake band is embedded in the brake lining on metal tape and is formed by the braking metal tape and muti-piece of one piece of entirety, should
The shortcomings that planting common brake band is that brake force is uneven.The phenomenon that being easy to appear local eccentric wear causes the time to grow rear braking
Effect is deteriorated, and reduces braking tape lifetime.
Utility model content
The technical issues of the utility model solves is: braking caused by local eccentric wear occurs in transmission brake structure brake band
Effect is poor, and the service life reduces fast problem.
Provided technical solution is the utility model to solve above-mentioned technical problem:
A kind of engineering machinery brake structure, including end block, pull rod, end block and pull rod are connected by drag link mechanism and brake band
Connect, further include main brake band and auxiliary braking band, the main brake band and auxiliary braking band discharge side by side, main brake band tail end and
Auxiliary braking band tail end is rotatablely connected；Main brake band and auxiliary braking band are pulled simultaneously, and the interaction of two brake bands makes to make
Power is more evenly distributed.
The auxiliary braking band is two, is listed in main brake band two sides, and tail end connects with main brake band tail end rotation respectively
It connects；Two sides auxiliary braking band, which is distributed in two sides, makes brake force more evenly.
The rotation connection is axis connection.
The utility model beneficial effect is: two sides auxiliary braking band is connected with the tail end of main brake band, is drawn by pull rod
Tight braking makes brake force be evenly distributed, and does not occur eccentric wear and over worn appearance.
Detailed description of the invention
Fig. 1 is a kind of engineering machinery brake structure schematic diagram；
Wherein, 1, end block, 2, pull rod, 3, auxiliary braking band, 4, main brake band.
Specific embodiment
Include end block 1, pull rod 2, auxiliary braking band 3, main brake band 4 in the utility model referring to attached drawing, end block 1 and draws
Bar 2 is connected by drag link mechanism mechanism, and 2 bottom end of pull rod is connect with 4 head end of main brake band, the tail end point of two auxiliary braking bands 3
Other and main brake band 4 tail end axis connection；1 tip of end block is against 3 tail end of auxiliary braking band, and 2 sets of the pull rod is in main system
Dynamic 4 head end of band.
When pulling pull rod 2, end block 1 and pull rod 2 are shunk simultaneously under the action of drag link mechanism, 4 head end quilt of main brake band
Pull rod 2 is held to contract, and 3 head end of auxiliary braking band is held by the head end of pull rod 2, and pull rod 2 is tightened, and main brake band 4 is driven
It inside contracts tightening simultaneously with auxiliary braking band 3 and completes braking.
