Specific embodiment
Specific embodiment 1: illustrate present embodiment in conjunction with Fig. 1~5, rubber is used in a kind of motor train unit train equipment compartment sealing
Cushion rubber, it includes rubber ring main body 1, the first connecting portion 2 for being installed in 1 one end outer wall of rubber ring main body and is installed in rubber
The second connecting portion 3 of 1 the other end inner wall of main body is enclosed, the rubber ring main body 1 is predeformation structure, the first connecting portion 2
Longitudinal section and the longitudinal section of the second connecting portion 3 be T-shaped structure, and one end of first connecting portion 2 and rubber ring main body 1
The other end in portion, second connecting portion 3 and rubber ring main body 1 is in I-shape construction arrangement, and the outside of first connecting portion 2 is arranged
There is the first metal external member 4, and the top of rubber ring main body 1, first connecting portion 2 and the first metal external member 4 pass through bolt simultaneously
It being installed on traction electric machine bottom plate 100, the outer cover of second connecting portion 3 is equipped with the second metal external member 5, and rubber ring main body 1
Lower part, second connecting portion 3 and the second metal external member 5 are installed on equipment compartment 101 by bolt simultaneously, and rubber ring main body 1 is
Integrally formed rectangular loop, its own intensity and leakproofness are higher, are arranged with the shape with traction electric machine bottom plate 100 and equipment compartment 101.
Upper part and traction electric machine plate are affixed, and lower part and equipment compartment 101 are affixed, in the operational process of EMU, seal, and prevent
Only outer gas stream, foreign matter (especially sand, stone and liquid oil and water) invade equipment compartment 101, can resist high temperature, it is high and cold and
The erosion of dust storm.In the operational process of EMU, traction electric machine bottom plate 100, which is pulled motor oscillating, can leave initial bit
It sets, traction electric machine bottom plate 100 and the relative distance of equipment compartment 101 is made to become larger, the edge also with becoming larger for distance of rubber ring main body 1
Extending longitudinally deformation.Since rubber ring is using the special construction of predeformation, when rubber ring elongation, avoid making rubber ring
The practical parts thinner for bearing pulling force, considerably increases use intensity and the service life of rubber ring.
Since EMU will receive frequent and violent vibration, effect of the rubber ring in alternate stress in the process of running
Lower repeated multiple times to be compressed and be stretched, the predeformation structure of rubber ring main body 1 makes rubber ring and traction electric machine bottom plate 100
Connection more closely, can not excessively extend in the state of being stretched, keep the elasticity of rubber ring.Predeformation structure use to
Indent smooth transition, does not occur sharp salient point under compressed state, will not damage and rupture because of multiple compression, effectively
Enhance the ability of its tear-proof and endurance aging.
The upper and lower ends of rubber ring main body 1 are integrally molded so as I-shaped structure with two interconnecting pieces respectively, penetrate metallic sheath
It in part, is securely fixed in rubber ring between traction electric machine bottom plate 100 and equipment compartment 101, prevents from tearing in vibration processes
Split rubber strip.
When relative distance minimum between traction electric machine bottom plate 100 and equipment compartment 101, rubber ring main body 1 is compressive state.
Guarantee that rubber ring bears excessive during elongation when the relative distance of traction electric machine bottom plate 100 and equipment compartment 101 becomes larger
Pulling force, further increase the use intensity of rubber ring.
The arc-shaped structure in middle part when rubber ring main body 1 is compressive state, in the short transverse of longitudinal section.Rubber ring master
The principal part of body 1 is the part actually withstood forces in 1 drawing process of rubber ring main body, is set to arcuate structure, effectively prevent
The appearance of the sharp salient point in stretching and compression process of rubber ring main body 1 effectively reduces and damages and rupture because repeatedly compressing
May, and then enhance the ability of its tear-proof and endurance aging.
The arcuate structure is recessed to 1 inside of rubber ring main body.While guaranteeing its tear-proof and endurance aging ability,
Keep the sealing structure between traction electric machine bottom plate 100 and equipment compartment 101 cleaner and tidier.
The longitudinal section of rubber ring main body 1 is arc between middle part and its adjacent top, lower part in the height direction
Transition.It is arc-shaped transition between the upper, middle and lower portion of rubber ring main body 1, rubber ring main body 1 is effectively prevent to stretch and compressing
The appearance of sharp salient point in the process effectively reduces the possibility damaged and ruptured because repeatedly compressing, so enhance its tear-proof and
The ability of endurance aging.
Each metal external member include four curved corner parts 6 and four strip pieces 7, per adjacent two curved corner parts 6 it
Between a strip piece 7 is set, and each curved corner part 6 and each strip piece 7 are set on its corresponding interconnecting piece.Rubber
The cross section for enclosing main body is rectangular configuration, and four curved corner parts are respectively sleeved at four corners of rubber ring main body, will be golden
Belong to external member subsection setup, guarantees installation and disassembly while it couples stability convenient for itself and rubber ring main body 1.
