Description
Technical field
The utility model belongs to colliery digging equipment technical field, is related to a kind of digger traveling mechanism brake.
Background technology
The mode of braking of existing digger traveling mechanism is to compress dynamic brake block and quiet brake block by hydraulic means, is made
Enough frictional force is produced between brake block and quiet brake block, and then realizes the purpose of braking.The problem of existing be：Due to mine
Influence of the dust to hydraulic system is larger, during equipment long service, and brake fluid system reliability is not high.
Utility model content
The purpose of this utility model is to solve that there is provided a kind of braking ability to the above mentioned problem that prior art is present
The higher digger traveling mechanism brake of good, reliability.
The technical solution taken for achieving the above object is such：The digger traveling mechanism provided
Brake include barrel housing and in housing and be sleeved on digger traveling mechanism wheel shaft yoke assembly, armature,
Diaphragm spring, driver blade and friction disc brake component, end cap, the interior yoke assembly provided with magnet coil are equipped with one end of housing
It is fixed on by holding screw on wheel shaft, one end of armature is contradicted by back-moving spring and yoke assembly, other end socket diaphragm
Spring, one end that diaphragm spring is relatively large in diameter is mounted connected to inner walls fixation baffle ring by a circle and blocked, and diaphragm spring diameter is smaller
One end be located at friction disc brake component side, the another side of friction disc brake component is contacted with end cap.Need to driving
When machine walking mechanism is braked, yoke assembly is set to be powered, the magnet coil being fixed in yoke produces magnetic force and inhales moving armature shifting
Dynamic, the less one end of diaphragm spring diameter is moved with armature to yoke assembly side, the boss shape of diaphragm spring and fixed baffle ring
Into extruding, one end that diaphragm spring is relatively large in diameter is set to be deformed to driver blade side, so as to extrude driver blade and friction disc brake group
Part, so interior outside friction disc keeps geo-stationary, due to being connected between inner attrition piece and wheel shaft by flat key, when inner attrition piece is static
When, wheel shaft also remains stationary realizes braking.
In above-mentioned digger traveling mechanism brake, friction disc brake component is by multiple outside friction discs being alternately arranged and interior
Friction plate is constituted, and wherein outside friction disc is fixed by a pin between housing and end cap, and inner attrition piece is connected by flat key and wheel shaft
Connect.
Compared with prior art, the utility model has the advantages that easy to operate, braking ability is good, reliability is high.
Brief description of the drawings

Back-moving spring, 14- end caps, 15- fixing screws, 16- wheel shafts.
Embodiment
Referring to accompanying drawing, digger traveling mechanism brake described in the utility model by the barrel housing 3 with end cap 14,
And located at the yoke assembly 1 that housing 3 is interior and is sleeved on digger traveling mechanism wheel shaft 16, armature 7, diaphragm spring 2, transmission
The component such as piece 4 and friction disc brake component is constituted, and friction disc brake component therein is again by multiple outside friction discs 5 being alternately arranged
Constituted with inner attrition piece 6.Specific package assembly is that the interior yoke assembly 1 provided with magnet coil is socketed on axle, yoke assembly 1
It is fixed on by holding screw 8 on digger traveling mechanism wheel shaft 16, the one end of armature 7 socket diaphragm spring 2, the other end passes through multiple
Position spring 13 is contradicted with yoke assembly 1, and one end that diaphragm spring 2 is relatively large in diameter is blocked by the fixation baffle ring 9 with boss, fixed
Baffle ring 9 is fixedly connected by bolt with housing 3, and driver blade 4 is socketed on wheel shaft 16, the outside friction disc in friction disc brake component
Component 5 is connected between housing 3 and end cap 14 by pin 11, and is fixed by nut 10, and end cap 14 passes through fixation with housing 3
Screw 15 is fixed, and the inner attrition piece 6 in friction disc brake component is connected by flat key 12 with wheel shaft 16.
Operation principle of the present utility model is：Yoke assembly 1 is relative with armature 7, and armature 7 can be transported relative to yoke assembly 1
It is dynamic, there is back-moving spring 13 between armature 7 and yoke assembly 1；When needing braking, yoke assembly 1 is powered, and is fixed on the electricity in yoke
Magnetic coil produces magnetic force, inhales moving armature 7 and moves to left, armature 7 drives the less one end of the diameter of diaphragm spring 2 to move to left, and diaphragm spring 2 is straight
The larger one end in footpath produces deformation to the right, so as to extrude driver blade 4, outside friction disc 5 and inner attrition piece 6, outside friction disc 5 with it is interior
Larger pressure and frictional force are formed between friction plate 6, so as to keep geo-stationary, wheel shaft 16 is by flat key 12 and inner attrition piece 6
Connection, when inner attrition piece 6 is static, wheel shaft 16 is also static, so as to realize braking.
