Description
Technical Field
The invention relates to a damping rubber pile in secondary suspension of a locomotive bogie of a freight train, in particular to a horizontal hydraulic damping device integrated with the rubber pile, and belongs to the technical field of train damping.
Background
The existing secondary suspension of the passenger train uses an air spring as a damping part, and a locomotive of the freight train still uses a rubber pile with strong bearing capacity as the damping part of the secondary suspension at present due to large weight of the locomotive.
Like the air springs in the secondary suspension of a passenger train, the rubber piles of the freight train locomotive are subjected to varying vertical forces during the operation of the freight train due to uneven roads, varying longitudinal forces during the change (acceleration and deceleration) of the train operation speed, and varying lateral forces during the passage of the train through curves. We refer to both longitudinal and transverse forces acting on the rubber mass as forces in the horizontal direction. In practice, the rubber pile is often subjected to forces in the horizontal direction not only to a single longitudinal or transverse force, but also to both longitudinal and transverse forces, such as moderate deceleration of the train as it passes through a curve.
Because the traditional rubber pile has high elastic rigidity, the restoring force attenuation along the horizontal direction is weakened, the vibration reduction effect is poor, the stable operation of a train is not facilitated, and the train is caused to frequently suffer from overload impact between a movable part and a contact part when the train operates, so that the abrasion of related parts (mainly between wheel rails) is intensified. In order to solve the problem, the traditional two-system vibration damper has to be specially provided with a transverse vibration damper and a longitudinal vibration damper for transverse and longitudinal vibration damping except for the rubber pile, so as to achieve the purposes of energy absorption and vibration damping. This not only increases the component arrangement of the bogie, but also is generally regarded in the industry as less than ideal in damping effect. However, for the rubber piles under heavy load, an effective technical solution has not been formed in the industry for endowing the rubber piles with ideal damping and vibration attenuation characteristics.

Detailed Description
The invention is further described below with reference to examples and figures:
as shown in FIGS. 1 to 7, in the following description, the parts rubber pile 1, bottom plate 2, side wall 21, top plate 3
The hydraulic ring 4, the lateral pressure ring 5, the pressure receiving ring 6 and the mounting ring 7 are circular in horizontal cross section and have a common axial center line in the apparatus according to the invention when the rubber pile is not inclined.
As shown in fig. 1, a horizontal hydraulic damping device integrated with a rubber pile comprises a rubber pile 1, the rubber pile 1 is provided with a bottom plate 2 arranged at the bottom of the rubber pile 1, a top plate 3 arranged at the top of the rubber pile 1, and a hydraulic ring 4 with an annular cavity; the hydraulic ring 4 is made of flexible material with elasticity, so that the hydraulic ring can deform when stressed and can restore to the original shape when the stress is relieved. A damping mechanism is arranged in an annular cavity of the hydraulic ring 4 and filled with damping liquid, a cylindrical side wall 21 rising upwards is arranged on the outer edge of the bottom plate 2, and the hydraulic ring 4 is arranged on the upper part of the inner wall of the side wall 21; when the speed of the train changes or enters a curve to run in the running process of the train and the running speed of the train changes when the train enters the curve to run, the rubber pile 1 is stressed to incline along the longitudinal direction or the transverse direction or along any direction of the horizontal direction, one side of the top plate 3 at the top of the rubber pile 1 in the inclining direction can touch and extrude the hydraulic ring 4 at the side, and damping liquid in the hydraulic ring 4 flows under pressure and absorbs energy and reduces vibration through the damping mechanism. Therefore, the rubber pile is directly endowed with the horizontal damping characteristics including but not limited to the transverse and longitudinal damping characteristics, the problems of the traditional rubber pile that the elastic rigidity is too large, the restoring force attenuation is weakened and the damping effect is poor are solved, and the running of the train during starting, braking and passing curves becomes more stable. Therefore, the transverse shock absorber and the longitudinal shock absorber do not need to be specially arranged in the limited installation space of the bogie, and the bogie is simpler to arrange. By taking the scheme of the invention as a breakthrough, a large re-optimization space exists in the future, and after optimization, the rubber pile of the hydraulic damping device which is arranged integrally with the rubber pile on the bogie has better damping effect than the existing bogie which is provided with the rubber pile and an external transverse and longitudinal damper.
As shown in fig. 1-3 and 8, a damping mechanism is arranged in the annular cavity of the hydraulic ring 4, and a plurality of damping transverse partitions 42 are circumferentially arranged in the annular cavity of the hydraulic ring 4 to divide the annular cavity into a plurality of damping liquid cavities 41; the damping diaphragm 42 is provided with a damping hole 43 for communicating two adjacent damping liquid cavities 41. Thus, when the hydraulic ring 4 is squeezed at any position, the damping fluid in the squeezed damping fluid chamber 41 will be squeezed into the adjacent damping fluid chamber 41 through the damping holes 43 formed in the damping diaphragms 42 at both ends. The damping diaphragm 42 also serves to support the hydraulic ring 4 and prevent the inner ring of the hydraulic ring 4, which is far from the side wall 21, from sagging.
In the above configuration, although the plurality of damping diaphragms 42 are provided in the entire annular cavity, all the damping fluid chambers 41 of the entire annular cavity are communicated with each other through the damping holes 43 provided in the damping diaphragms 42. When the damping fluid chamber 41 is squeezed, the damping fluid in the damping fluid chamber 41 with high pressure inevitably squeezes into the adjacent damping fluid chamber 41 with low pressure through the damping holes 43 arranged on the damping diaphragms 42, and is sequentially transferred in this way, as shown in fig. 8.
The damping diaphragm 42 can generate resilient elastic deformation when stressed. This is because the force applied to the rubber pile 1 may not be a transverse force or a longitudinal force, for example, when a train accelerates or decelerates through a curve, the hydraulic ring 4 may be pressed at any position, that is, the damping diaphragm 42 at any position may be deformed by pressing, and it is necessary that the damping diaphragm 42 has good resilience.
Among the plurality of damping fluid chambers 41 of the hydraulic ring 4, one damping fluid chamber 41 is located right in front of the rubber pile 1, one damping fluid chamber 41 is located right behind the rubber pile 1, one damping fluid chamber 41 is located right left of the rubber pile 1, and one damping fluid chamber 41 is located right of the rubber pile 1.
The reason for this is that the probability of the rubber pile 1 being subjected to the change of the pure longitudinal force and the change of the pure transverse force is the greatest, the frequency of the rubber pile 1 inclining to the right front, right back, right left and right is the highest, the damping effect is better when just one damping liquid cavity 41 is extruded by one-time inclination, and the probability of the damping diaphragm 42 being extruded can be correspondingly reduced.
The volume of the damping fluid cavity 41 right on the left of the rubber pile 1 is equal to the volume of the damping fluid cavity 41 right on the right of the rubber pile 1. This is because it can be determined that the probability and magnitude of the inclination of the rubber pile 1 to the left and right are substantially equal.
As shown in fig. 1, the height of the upper end surface of the sidewall 21 at the outer edge of the bottom plate 2 is lower than the height of the top end surface of the top plate 3, and the height difference between the two is larger than the maximum compression stroke when the train body vertically compresses the rubber pile 1. The height of the upper end surface of the hydraulic ring 4 provided at the upper portion of the inner wall of the side wall 21 is lower than or equal to the height of the upper end surface of the side wall 21. The arrangement is that when the road is not smooth, the running train generates vertical vibration, and the train body can not touch the side wall 21 at the outer edge of the bottom plate 2 and the hydraulic ring 4 arranged on the upper part of the inner wall of the side wall 21 when sinking.
As shown in fig. 1-3, the outer edge of the top plate 3 is provided with a side pressing ring 5, the upper end of the side pressing ring 5 is sleeved on the outer edge of the top plate 3 and fixed with the outer edge of the top plate 3, and the lower end face of the side pressing ring 5 extends downwards to a height below the end face of the upper end of the side wall 21. This is provided to enable the side press ring 5 to press the hydraulic ring 4 lower than the top plate 3 when the rubber pile 1 is inclined.
The inner circle of hydraulic pressure circle 4 is equipped with the compression ring 6 that bonds with the inner circle face of hydraulic pressure circle 4, the compression ring 6 cover is outside side clamping ring 5, when rubber heap 1 receives arbitrary horizontal direction effort to take place to incline, side clamping ring 5 can both touch and oppress compression ring 6.
As shown in fig. 4 and 5, a plurality of crimping members capable of applying a pressing force and a pulling force to the pressure receiving ring 6 are provided at equal intervals on the outer periphery of the side compression ring 5; and the compression ring 6 is provided with a buckling structure correspondingly connected with the buckling part on the side compression ring 5.
The buckling part comprises a bolt 51 and a connecting block 52, the bolt is vertically arranged, and the connecting block 52
The plug pin 51 is fixedly connected with the side pressure ring 5 between the plug pin 51 and the side pressure ring 5;
as shown in fig. 4 to 7, the buckling structure includes an insertion hole 61 vertically arranged on the compression ring 6, into which the plug 51 can be inserted, and which horizontally limits the plug 51, and the insertion hole 61 has a vertical opening 62 vertically opened on the inner side of the compression ring 6;
after assembly, the plug 51 is inserted into the jack 61, the connecting block 52 is positioned in the vertical opening 62 of the jack 61, and the plug 51 can slide vertically in the jack 61.
As shown in fig. 1 to 8, the above-mentioned setting principle is: when the pressure receiving ring 6 extrudes one or more damping fluid chambers 41 at a certain position of the hydraulic ring 4 to form positive pressure, other non-extruded damping fluid chambers 41 are stretched to form negative pressure, so that the damping fluid in the whole hydraulic ring 4 is promoted to flow through all the damping holes 43, and the optimal damping energy absorption effect is obtained. Therefore, the outer peripheral surface of the pressure receiving ring 6 is designed to be bonded to the inner ring surface of the hydraulic ring 4. In this way, while the pressure receiving ring 6 presses one or more damping fluid chambers 41 in a certain portion of the hydraulic ring 4, the other damping fluid chambers 41 that are not pressed are stretched by the pressure receiving ring 6.
Furthermore, the pressure ring 6 is provided with a buckling structure, the outer periphery of the side pressure ring 5 is provided with buckling parts, the pins 51 of the buckling parts are inserted into the insertion holes 61 of the buckling structure, the side pressure ring 5 can apply pressure to the pressure ring 6 in a certain direction through the matching of the pins 51 and the insertion holes 61, meanwhile, the side pressure ring 5 can apply tension to the pressure ring 6 in the opposite direction through the matching of the pins 51 and the insertion holes 61, and the whole stress integrity of the whole device is enhanced.
The outer periphery of the side pressure ring 5 is provided with a plurality of buckling components capable of applying pressure and pulling force to the pressure receiving ring 6 at equal intervals, and the pressure receiving ring 6 is provided with a buckling structure correspondingly connected with the buckling components on the side pressure ring 5. This is actually a spaced design to reduce the contact area between the pressure ring 6 and the side pressure ring 5. In practical applications, the fit clearance between the plug 51 and the socket 61 is minimized, and a lubricant may be used between the plug 51 and the socket 61.
The plug 51 may have various shapes such as a block, a cylinder, etc., and a cylinder having an oval cross-section is illustrated.
The outer ring of the hydraulic ring 4 is provided with a mounting ring 7 which is bonded with the hydraulic ring 4; correspondingly, the upper end of the inner wall of the side wall 21 is provided with an L-shaped mounting position 8 with a section opened outwards along the radial direction of the inner wall, and an annular shelf 81 is formed between the mounting position 8 and the inner wall of the side wall 21 below; during assembly, the mounting ring 7 of the hydraulic ring 4 is inserted into the mounting position 8 from top to bottom until the lower end surface of the mounting ring 7 contacts with the annular shelf 81.
