Abstract
A kind of Hydraulic brake cylinder assembly, including Hydraulic brake cylinder (1), the piston rod (2) of the Hydraulic brake cylinder (1) coordinate with U-shaped fork (4), it is characterised in that：Locking nut (3) is housed on the outside of the U-shaped fork (4), the U-shaped fork (4) uses with the piston rod (2) to be threadedly coupled, cancel positive/negative thread type of attachment, only retain the threaded connection between piston rod one end and U-shaped fork (4).The U-shaped fork of brake cylinder is threadedly coupled with piston rod using length after improvement, and locking with locking nut, and due to being threadedly coupled using long, even if producing loosening, U-shaped fork will not be mutually disengaged with piston rod, so as to avoid the generation of case accident.Structure type is simpler reliable compared to original structure, and maintenanceability is stronger, and can effectively reduce cost.
Description
Technical field
A kind of oil cylinder is the utility model is related to, particularly a kind of Hydraulic brake cylinder assembly for large-scale maintenance machinery,
Belong to railway machinery design and manufacturing technology field.
Background technology
Hydraulic brake cylinder is the very high component of frequency of use, and threaded post 6 ' is connected with cylinder piston rod 2 ' by screw thread
Connect, cylinder piston rod 2 ' is likely to occur during long-term job execution or under the influence of other factors and threaded post 6 ' connects out
The situation of place 7 ' and fracture is now loosened, there are security risk.The common condition loosened as shown in Figure 1 for threaded post 6 ' with oil cylinder.
Utility model content
A kind of Hydraulic brake cylinder assembly, including Hydraulic brake cylinder, the piston rod of the Hydraulic brake cylinder are matched somebody with somebody with U-shaped fork
Conjunction, U-shaped fork outside are equipped with locking nut, and the U-shaped fork is used with the piston rod to be threadedly coupled, but cancels originally positive and negative
Threaded form, only retains the threaded connection between piston rod one end and U-shaped fork, and structure is simpler.
Preferably, the threaded connection between original threaded post and cylinder piston rod is cancelled, by U-shaped fork and original screw thread
Column is integrally formed, i.e. U-shaped fork only includes internal thread, rather than U-shaped fork is set with positive and negative spiral shell via original external screw thread
Set, then connects piston rod by positive and negative swivel nut again, and improved structure is simpler.
In any of the above-described scheme preferably, the axial length of the internal thread of the U-shaped fork is not less than 120mm.
Preferably, the piston rod includes external screw thread, on the piston rod external screw thread along piston rod to length it is not small
In 120mm.
The U-shaped fork of brake cylinder is threadedly coupled with piston rod using length after improvement, and locking with locking nut, due to using
Long to be threadedly coupled, even if producing loosening, U-shaped fork will not be mutually disengaged with piston rod, so as to avoid the generation of case accident.
Structure type is simpler reliable compared to original structure, and maintenanceability is stronger, and can effectively reduce cost.
The technical solution of Hydraulic brake cylinder assembly provided by the utility model includes any combination of each part mentioned above,
The simple change of each part mentioned above component or combination are still the scope of protection of the utility model.
Brief description of the drawings
Fig. 1 is to show the common condition that threaded post is loosened with oil cylinder in the prior art；
Fig. 2 is the structure diagram of a preferred embodiment of Hydraulic brake cylinder assembly described in the utility model；
Fig. 3 is the A-A of embodiment illustrated in fig. 2 to partial sectional view；
Numeral represents respectively in Fig. 2-Fig. 3：
1 Hydraulic brake cylinder, 2 piston rod, 3 locking nut, 4 U-shaped fork
1 ' Hydraulic brake cylinder, 3 ' locking nut, 4 ' U-shaped fork
5 ' the positive and negative threaded posts of swivel nut 6 ' 7 ' loosen place.
Embodiment
The utility model in order to better understand, is described in detail a kind of hydraulic pressure according to the utility model below in conjunction with the accompanying drawings
The preferred embodiment of brake cylinder assembly.
Embodiment one：A kind of Hydraulic brake cylinder assembly, including Hydraulic brake cylinder 1, the piston of the Hydraulic brake cylinder 1
Bar 2 pitches 4 cooperations with U-shaped, which is equipped with locking nut 3, and the U-shaped fork 4 is used with piston rod 2 to be threadedly coupled,
Have between 2 one end of piston rod and U-shaped fork 4 using being threadedly coupled, structure is simpler.
In the present embodiment, cancel the threaded connection between original threaded post and cylinder piston rod, by U-shaped fork 4 and originally
Threaded post is integrally formed, i.e. U-shaped fork 4 only includes internal thread, rather than the threaded post 6 ' via U-shaped fork 4 ' and positive and negative spiral shell
The connection of set 5 ', then connects piston rod by positive and negative swivel nut 5 ' again, and locking nut 3 ' only needs one, reduces what is loosened
Risk, and the structure of improved Hydraulic brake cylinder 1 ' is simpler.
In the present embodiment, the axial length of the internal thread of U-shaped fork 4 is 120mm, and piston rod 2 includes external screw thread, the piston rod
External screw thread is 120mm along the axial length of piston rod 2 on 2, and tightening nut 3 is sleeved on piston rod 2 and pitches 4 ends positioned at U-shaped,
To lock the U-shaped fork 4 and piston rod 2.
U-shaped fork 4 and piston rod 3 are threadedly coupled using growing, and carried out with locking nut 3 it is locking, it is U-shaped even if loosening
Fork 4 will not be mutually disengaged with piston rod 2, avoid the generation again of case accident.
Structure type compares original structure, and structure is simpler safe and reliable, and maintenanceability is stronger.
