The inventor of the present invention found through research and analysis that the existing wear assembly schemes are: wearing plate installs on the coupling, and bellows intermediate junction frame overlap joint is in the middle of two backstops, and the motion of restriction bellows intermediate junction frame in the car length direction makes bellows intermediate junction frame placed in the middle. The wearing component ensures that the middle connecting frame of the folding shed does not limit in the vehicle width direction during the running process of the railway vehicle, particularly during the turning process, and the middle connecting frame of the folding shed can move laterally relative to the wearing plate, so that the superposition area of the projections of the middle connecting frame of the folding shed and the wearing plate on the horizontal plane is the area of the middle connecting frame of the folding shed and the wearing plate which generate lateral offset friction, and because the area is smaller, the friction stress is concentrated, and larger wear and abnormal sound are generated; in addition, the middle connecting frame of the folding shed rotates on the wearing plate, and relatively serious abnormal sound is generated between the middle connecting frame of the folding shed and the backstop of the wearing plate, so that the comfort is influenced; when the rail vehicle passes through a more complex route (such as an S-shaped curve), the two stopping blocks have the risk of clamping the middle connecting frame of the folding shed; when the gravity center of the through passage deviates, even the possibility that the middle connecting frame of the folding shed is in line contact with the wearing plate exists, the abrasion is aggravated, and the abnormal sound is aggravated. For the reasons, the inventor improves the existing abrasion assembly to obtain the technical scheme of the invention.
A wear assembly and through passage in accordance with an embodiment of the present invention will now be described in detail with reference to figures 1-10.
Example one
As shown in fig. 1-5, a wear assembly of an embodiment of the present invention includes a wear block 1, a wear plate 2, and a transition table 4. The through passage of embodiments of the present invention includes a bellows assembly (not shown) and a wear assembly provided by embodiments of the present invention. The bellows assembly comprises two bellows bodies (not shown in the figure) and a bellows intermediate connecting frame 3.
As shown in fig. 2 and 4, the transition table 4 includes a friction block 41. The wear block 1 is U-shaped. In particular, the longitudinal section of the wear strip 1 is U-shaped, i.e. its projection in the longitudinal vertical plane (yOz plane) is U-shaped. The cross-sectional shape of the wear strip 1, i.e. the wear block 1, is U-shaped. The wear block 1 comprises two side plates 11 and a bottom plate 12. The two side plates 11 are each provided with three first bolt holes 1a, for a total of six first bolt holes 1 a. Preferably, the friction pad 41 is cylindrical and includes an outer annular surface and a bottom surface. The abrasion block 1 is fixedly connected with the abrasion round block 41; preferably, the wear block 1 and the friction block 41 are integrally formed.
As shown in fig. 2 and 5, the transition table 4 further includes a friction groove 42. The wear plate 2 is a rectangular plate including eight second bolt holes 2 a. The wearing plate 2 is fixedly connected with the wearing circular groove 42; preferably, wear plate 2 and friction groove 42 are integrally formed. Friction groove 42 is provided at the center of wear plate 2, and friction groove 41 is preferably a circular groove including an inner annular surface and an inner planar surface.
As shown in fig. 9, the middle connection frame 3 of the bellows is a rectangular frame, and comprises a bottom frame 30; the bottom frame 30 is a hollow frame having a rectangular longitudinal section. Two side surfaces of the bottom frame 30 of the bellows intermediate connection frame 3 are respectively provided with three third bolt holes 3a, and the total number of the third bolt holes 3a is six.
As shown in fig. 2-3, the bottom frame 30 of the middle connection frame 3 of the bellows is in contact fit with the bottom plate 12 of the wearing block 1 and is fixedly connected with the two side plates 11 of the wearing block 1 through three bolts. The three bolts ensure the strength of the fixed connection between the wearing block 1 and the folding shed middle connecting frame 3, and the connection reliability is improved. The wearing plate 2 is fixedly connected with a coupler (not shown in the figure) through eight bolts. The strength of the fixed connection between the wearing plate 2 and the car coupler is guaranteed by the eight bolts, and the connection reliability is improved.
As shown in fig. 1-3, the bottom surface of friction block 41 integral with wear block 1 is in contact engagement with the inner planar surface of friction groove 42 integral with wear plate 2; the outer annular surface of the friction pad 41 integral with the wear pad 1 and the inner annular surface of the friction groove 42 integral with the wear plate 2 are in clearance fit so that the wear pad 1 and the wear plate 2 can freely rotate relative to each other about the axis of the friction pad 41. The friction block 41 and the friction groove 42 are matched to realize that the abrasion block 1 and the abrasion plate 2 can rotate around the fixed shaft, and the rotary friction contact between the abrasion block 1 and the abrasion plate 2 obtains a larger contact area, so that the structure is simple and reliable. Because the friction groove 42 is arranged at the central position of the wearing plate 2, the stress environment of the wearing block 1 and the wearing plate 2 in operation is more stable.
The bellows assembly is a flexible member, and both ends are connected to the front and rear vehicle bodies, respectively. When the railway vehicle turns, the car coupler drives the wearing plate 2, the wearing plate 2 drives the wearing block 1, the wearing block 1 drives the folding shed middle connecting frame 3 to deviate to the outer side of the curve, and the folding shed assembly is adapted to the position change of the folding shed middle connecting frame 3 to deform to a certain extent. In the process, the connecting position of the wearing block 1 and the middle connecting frame 3 of the bellows and the connecting position of the wearing plate 2 and the car coupler cannot move relatively, so that the motion requirement of the bellows assembly in steering is met.
Through wearing and tearing piece 1 and the 3 fixed connection of bellows intermediate junction frame, spacing has been carried out on bellows intermediate junction frame 3 in the length direction of the car for the deformation of two bellows bodies in front of bellows intermediate junction frame 3 back keeps at certain limit, has guaranteed the stability of link-up way when rail vehicle turns to.
When the railway vehicle is turned, the wearing block 1 and the wearing plate 2 can freely rotate around the axis of the friction block 41, so that the wearing block 1 and the wearing plate 2 are prevented from generating lateral offset friction and rotary clamping; because the friction block 41 and the friction groove 42 are in rotary friction contact, the friction contact area is large, the friction stress is low, and the abrasion concentration is avoided. The abrasion component provided by the embodiment of the invention effectively reduces the serious abrasion and the sharp abnormal sound generated in the working process of the friction component, ensures the riding comfort and prolongs the service life of the abrasion component provided by the embodiment of the invention.
As shown in fig. 2, the friction block 41 has a wear observation hole 41a in a bottom surface thereof. By visually observing the change in the depth of the wear observation hole 41a, the wear of the bottom surface of the wear block 41 can be roughly determined, and the use of the wear member can be determined. The depth of the abrasion observation hole 41a is 3-5 mm; preferably, the depth of the wear observation hole 41a is 4 mm; the depth of the wear observation hole 41a is the vertical length of the wear observation hole 41 a. Since the amount of wear of the bottom surface of the wear block 41 is relatively small, the amount of wear of the bottom surface of the wear block 41 can be easily determined visually with a simple method with respect to a shallow hole having a depth of 4 mm, i.e., the wear observation hole 41a, and thus it is not necessary to measure the amount of wear of the bottom surface of the wear block 41 with a measuring tool.
In the wear assembly provided by the embodiments of the present invention, the friction grooves 42 are also coated with grease. The lubricating grease can be stored for a long time, and can further reduce friction, slow down abrasion, reduce noise and prolong the service life of the abrasion plate and the abrasion block.
Preferably, wear plates 2 are selected from one or more of carbon steel, nylon, or ultra high molecular weight polyethylene. The carbon steel can meet the strength requirement of the abrasion plate 2 on complex stress in the working process, is easy to obtain and is convenient to cast. Ultra-high molecular weight polyethylene refers to unbranched linear polyethylene having a molecular weight of 150 ten thousand or more. The nylon and the ultra-high molecular weight polyethylene have ultra-strong wear resistance and self-lubricating property, higher strength, stable chemical property and strong ageing resistance, and can greatly reduce the wear and abnormal sound generated in the working process of the wear assembly.
In the through passage provided by the embodiment of the invention, the two folding shed bodies are connected through the middle connecting frame 3 of the folding shed. Because the folding shed body is a flexible part, the folding shed assembly has a sinking trend for a through passage with larger length. The car coupler is connected with the middle connecting frame 3 of the folding shed through the abrasion assembly provided by the embodiment of the invention, so that the car coupler plays a supporting role on the middle connecting frame of the folding shed, and the sinking of the folding shed assembly is avoided.
In another embodiment of the present invention, the bellows assembly further comprises a wear block mounting frame 31, as shown in fig. 10. The wearing block mounting frame 31 is a hollow frame, and its longitudinal section is rectangular. The top of the wearing block mounting frame 31 is welded with the bottom frame 30 of the bellows middle connecting frame 3. Two side surfaces of the wearing block mounting frame 31 are provided with three third bolt holes 3a, and six third bolt holes 3a are provided. The wearing block mounting frame 31 is fixedly connected with the wearing block 1 through bolts. The wearing block mounting frame 31 replaces the folding shed middle connecting frame 3 to be connected with the wearing block 1 through bolts, and plays a role in protecting the folding shed middle connecting frame 3.
Example two
Figures 6-8 illustrate another embodiment of the present invention providing a wear assembly that is a variation of the wear assembly of figures 1-5 (i.e., the wear assembly of embodiment one of the present invention) and which differs from the wear assembly of figures 1-5 by including:
as shown in fig. 7, the wear block 1 is fixedly connected with the friction groove 42; preferably, wear block 1 and friction groove 42 are integrally formed. As shown in fig. 8, the wear plate 2 and the friction block 41 are fixedly connected; preferably, wear plate 2 and friction block 41 are welded or integrally formed. The friction block 41 is provided at the center of the wear plate 2.
As shown in fig. 6, the inner flat surface of friction groove 42 integral with wear block 1 is in contact engagement with the top surface of friction block 41 integral with wear plate 2; the inner ring surface of the friction groove 42 integral with the wear block 1 and the outer ring surface of the friction block 41 integral with the wear plate 2 are in clearance fit so that the wear block 1 and the wear plate 2 can freely rotate relative to each other about the axis of the friction block 41.
The friction block 41 and the friction groove 42 are matched to realize that the abrasion block 1 and the abrasion plate 2 can rotate around the fixed shaft, and the rotary friction contact between the abrasion block 1 and the abrasion plate 2 obtains a larger contact area, so that the structure is simple and reliable. Because the friction block 41 is arranged at the central position of the wearing plate 2, the stress environment of the wearing block 1 and the wearing plate 2 in operation is more stable.
As shown in fig. 6 and 8, the friction block 41 is provided with a wear observation hole 41a on the top surface. By visually observing the change in the depth of the wear observation hole 41a, the wear of the top surface of the wear round 41 can be roughly determined, and the use of the wear member can be determined. The depth of the abrasion observation hole 41a is 3-5 mm; preferably, the depth of the wear observation hole 41a is 4 mm; the depth of the wear observation hole 41a is the vertical length of the wear observation hole 41 a. Since the wear amount of the top surface of the wear block 41 is relatively small, the wear amount of the top surface of the wear block 41 can be easily roughly determined by the naked eye with respect to a shallow hole having a depth of 4 mm, that is, the wear observation hole 41a, and thus it is not necessary to measure the wear amount of the top surface of the wear block 41 with a measuring tool.
When the railway vehicle is turned, the wearing block 1 and the wearing plate 2 can freely rotate around the axis of the friction block 41, so that the wearing block 1 and the wearing plate 2 are prevented from generating lateral offset friction and rotary clamping; because the friction block 41 and the friction groove 42 are in rotary friction contact, the friction contact area is large, the friction stress is low, and the abrasion concentration is avoided. The abrasion component provided by the embodiment of the invention effectively reduces the serious abrasion and the sharp abnormal sound generated in the working process of the friction component, ensures the riding comfort and prolongs the service life of the abrasion component provided by the embodiment of the invention.
Other constructions and operations of the rail transit system according to embodiments of the invention are known to those skilled in the art and will not be described in detail herein.
