Description
Technical field
This utility model relates to brake unit, relates generally to one and is applied to mining hoist, crane gear and similar machine
Disk brake on tool equipment.
Background technology
The upper great majority of modern mining hoist (also known as hoist engine) use disk brake as brake unit, and its performance is good
Bad and working condition directly concerns the safety of personnel, equipment.There is twice hydraulic oil to seal in conventional disk brake structure, live
Plug is by the biggest being bolted on brake shoe cylinder of single pretightning force, and oil cylinder entirety is positioned on brake body, piston and oil
Occurring location between cylinder, the quality of fit of the machining accuracy of brake, oil cylinder and piston is desirable that the highest, makes manufacture and use
Safeguard the most extremely inconvenience.Once process and assemble overproof, easily causing piston eccentric with oil cylinder center, crooked, make piston and oil cylinder
Gap uneven, even produce in oil cylinder during piston movement and scrape the phenomenons such as cylinder, jam, the most also cause the High-pressure oil sealing life-span
Short, sealing effectiveness is poor, hydraulic oil easy oil leakage, directly affects the serviceability of brake, may cause equipment safe thing time serious
Therefore generation.
The utility model patent of published Application No. 200920090622.2, although more conventional product has had and changes more greatly
Enter, but structure still slightly complicated, there is unreasonable part, still have the space of Optimal improvements.
Summary of the invention
The purpose of this utility model is to provide another kind of disk brake structure, on the premise of ensureing brake performance,
Designed by optimization, make structure more rationally, simplify, also reduce processing and assembly precision requirement, to reducing, manufacturing cost is favourable.
The purpose of this utility model and solve its technical problem and realize the most by the following technical solutions.New according to this practicality
A kind of disk brake that type proposes, including braking body, cylinder, oil cylinder, piston, disk and brake shoe, wherein oil cylinder is placed in system
In dynamic body, the small end of piston is connected with disk, has oil groove and oil duct in oil cylinder, and oil duct communicates with fuel inlet neck；Cylinder
And it is integrated, before cylinder by being arranged on 3 outside oil cylinder and above turnbuckle and stop sleeve pretension between disk
End has brake shoe, braking body to be connected with outside base support；The inner chamber body of cylinder has disk spring and inner shield ring, the evagination of oil cylinder
Platform connects with disk spring；Described oil groove is annular, is arranged on one end of the inwall of oil cylinder, and communicates with oil duct.
The purpose of this utility model and solve its technical problem that following technical measures can also be used is further real
Existing.
Aforesaid disk brake, the big end of wherein said piston radially has oilhole, and this oilhole is connected with oil groove
Logical.
Aforesaid disk brake, wherein said cylinder cavity is provided with the high-pressure seal ring being connected with oil cylinder cover.
Compared with prior art, there is advantages below: by structure optimization, decrease amount of parts in this utility model,
Completely eliminate the mistake orientation problem of oil cylinder, piston, it is to avoid the jam that brings because of manufacturing and positioning errors and scrape cylinder.By high pressure
Sealing ring is arranged in cylinder cavity, and compresses with oil cylinder cover, and is formed between piston and seal structure reliably, has both decreased sealing
Link and seepage, also extend the life-span of sealing ring.Hydraulic oil passes through annular oil groove radially into arriving piston in the incipient stage
In big end cavity, reduce initialization oil pressure, improve the susceptiveness of brake.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole realities
Execute example.Based on the embodiment in this utility model, those of ordinary skill in the art are institute under not making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1, this utility model disk brake, including braking body 1, adjusting nut 4, oil cylinder 5, cylinder 2, live
Plug 7, disk 12 and brake shoe 3.In wherein oil cylinder 5 is placed in braking body 1, and locked by adjusting nut 4, the small end of piston 7
It is connected with disk 12, in oil cylinder 5, has oil groove 11 and oil duct 10, and oil duct 10 communicates with fuel inlet fitting 17；Cylinder 2 and disk 12 it
Between by being arranged on 3 outside oil cylinder and above turnbuckle 13 stop sleeve 14, pretension is integrated, and barrel front end has brake shoe
3, braking body 1 is connected with outside base support；The inner chamber body of cylinder 2 has disk spring 16 and inner shield ring 15, the evagination of oil cylinder 5
Platform connects with disk spring 16；Oil groove 11 is annular, is arranged on one end of the inwall of oil cylinder 5, and communicates with oil duct 10；At piston
The big end of 7 radially has oilhole, and this oilhole is connected with oil groove 11；High-pressure seal ring 8 is located at the inner chamber of oil cylinder 5, and with oil
Cylinder cap 9 is connected.
This device is so work: when the hydraulic oil with certain pressure passes through at fuel inlet neck 17 along oil duct 10
Enter in the annular oil groove 11 of oil cylinder 5, from radially in the big end cavity of piston 7, promote piston 7, disk 12, tension
Bolt 13, drives cylinder 2 to move right, and now oil cylinder 5 is locked on braking body 1 immovable because being adjusted nut 4, will make
Disk spring group 16 is in its pre-compressed state, continues to improve oil pressure and is i.e. in design maximum oil pressure value, disk spring group 16
Big its pre-compressed state.Now rotating adjusting nut 4, make oil cylinder 5 and cylinder 2 with brake shoe 3, entirety is moved to the left, to braking
Dish is close.When gap between brake shoe 3 and brake disc reaches predetermined value, (general≤1mm) stops the rotation and locks.Now with
The reduction of outside oil pressure, under the internal force of disk spring group 16 release promotes, cylinder 2, brake shoe 3 continue to brake disc close straight
To completely attaching to；Continuing to reduce hydraulic fluid pressure to zero, disk spring group 16 just discharges remaining pre-compression force to brake disc,
Brake is just in on-position, and power now is the maximum braking force that disc-brake produces.When again leading in oil cylinder 5
Entering the hydraulic oil of band predetermined work pressure, piston 7 just promotes disk 12, cylinder 2 and brake shoe 3 to move right, and leaves brake disc one
Set a distance, and make disk spring group 16 be again at pre-pressing state, this is the state of declutching.Disk brake is repeatedly in braking
Work under state and the state that declutches.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model
Protection domain within.
