Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the description of one step is done to the utility model:
Embodiment one
As shown in Figure 5, be fixed with positioning base 4 above axle box 5, be provided with the steel spring 2 of Coiled coil shape above positioning base 4, steel spring 2 supports the locomotive weight of truck frame more than 6.In order to reduce the vertical load that steel spring 2 bears, reducing the metal fatigue that in locomotive operation process, steel spring 2 produces, thus preventing steel spring 2 from rupturing, in steel spring 2, being provided with vertical backstop 1.Base chimb 132 and the positioning base 4 phase top of vertical backstop 1, because vertical backstop 1 and positioning base 4 are all gyro-rotors, make vertical backstop 1 can be stuck in positioning base 4.Framework guide 3 is provided with directly over vertical backstop 1, locomotive is when zero load, the rubber boss 12 of vertical backstop 1 just contacts with framework guide 3, and in the whole process of locomotive from zero load to maximum load, the load of primary spring is all by steel spring 2 and vertical backstop 1 common support, thus the vertical load making vertical backstop 1 can better reduce steel spring 2 to bear.
Although the rigidity increasing vertical backstop 1 can better reduce the vertical load that steel spring 2 bears, vertical backstop 1 rigidity is excessive, and locomotive has the risk of derailing, also can reduce the vibration damping of locomotive, noise reduction, also can reduce the comfort level of passenger.Therefore in order to allow vertical backstop 1 that locomotive can be avoided to derail, improve the comfort level of the vibration damping of locomotive, anti-acoustic capability and passenger, well can reduce again the vertical load that steel spring 2 bears, actv. prevents steel spring 2 from rupturing, just require below demand fulfillment: the initial rigidity of first vertical backstop 1 is little, and time initial, the amplitude of variation rigidity is less, make vertical backstop 1 just can have good effectiveness in vibration suppression when initial; Then along with framework guide 3 press down further time, the rigidity of vertical backstop 1 is wanted constantly to increase, and the speed of the now increase of rigidity wants very fast, the amplitude of variation rigidity will increase gradually, after making framework guide 3 press down certain distance, vertical backstop 1 can share larger vertical load, thus reduces the vertical load that bears of steel spring 2, and under ensureing overload operating mode driver train and wheel between the unlikely deterioration of position relationship.
In the whole process of this locomotive from zero load to maximum load, the load of primary spring is all by the structure of steel spring 2 and vertical backstop 1 common support, vertical backstop 1 can be made can better to share the load of primary spring, thus better reduce the metal fatigue that in locomotive operation process, steel spring 2 produces, better prevent steel spring 2 from rupturing.The rigidity of the vertical backstop 1 of the present embodiment is exactly the ratio of the distance that the boss top 121 of vertical backstop 1 load of bearing and vertical backstop 1 moves down.As shown in Figure 4, vertical backstop 1 distortion in Fig. 4 refers to the distance that the boss top 121 of vertical backstop 1 moves down to the stiffness curve of vertical backstop 1.
As shown in Figure 4, when the load that vertical backstop 1 is born increases from 0, stiffness curve is very mild, and initial stiffness curve is close to linear.That is, the initial rigidity of vertical backstop 1 is less, and the speed that rigidity increases is very slow.Such characteristic can allow vertical backstop 1 have good effectiveness in vibration suppression, can prevent locomotive from occurring derailing, and passenger has good comfort level.
And when vertical backstop 1 bears large load, now the amplitude of the variation rigidity of vertical backstop 1 is comparatively large, the speed that rigidity increases.Such characteristic can allow vertical backstop 1 share more load, better reduce the vertical load that steel spring 2 bears, thus the more effective steel spring 2 that prevents ruptures.
In addition, because the load during zero load of locomotive different automobile types is different, and different automobile types maximum load is also different, therefore different locomotives is different for the initial rigidity of vertical backstop 1 and the requirement of variation rigidity, and different locomotive is also different to the requirement that rigidity changes with the increase of load.So the variation rigidity of vertical backstop 1 and rigidity need regulate flexibly, to meet the specific requirement of dissimilar locomotive.
As shown in Figure 1, Figure 2 and Figure 3, vertical backstop 1 is axisymmetric gyro-rotor, and vertical backstop 1 comprises body of rubber 11, rubber boss 12 and base 13, and rubber boss 12 to comprise outside boss top 121 and boss 122, and rubber boss 12 is round table-like.Angle outside boss top 121 and boss between 122 is angle A, and annular flat straight section 111 is angle B with the angle of horizontal surface.Reduce the angle of angle A and angle B, the amplitude of the variation rigidity of vertical backstop 1 can be increased; Otherwise, increase the angle of angle A and angle B, the amplitude of the variation rigidity of vertical backstop 1 can be reduced.
The diameter of rubber boss 12 is D1, the height of rubber boss 12 is H1, outside annular arc section 112 and main body, the diameter of 113 intersections is D2, and increase the rigidity that D1 and D2 can increase vertical backstop 1, the height of increase body of rubber 11 and H1 can reduce the rigidity of vertical backstop 1; Otherwise reduce the rigidity that D1 and D2 can reduce vertical backstop 1, the height of reduction body of rubber 11 and H1 can increase the rigidity of vertical backstop 1.The preferred value of the preferred value of D1 to be the preferred value of 15mm-50mm, D2 be 75mm-85mm, H1 is 6mm-30mm; The preferred value of angle A is 100 degree of-150 degree, and the preferred value of angle B is 135 degree of-165 degree.
The rubber boss 12 of vertical backstop 1 and body of rubber 11 are a monoblock rubber, and body of rubber 11 and metal base 13 are sulfided into an entirety under certain temperature and pressure by adhesive.Be provided with one section of annular flat straight section 111 in the upper end of body of rubber 11, annular flat straight section 111 is connected by one section of annular arc section 112 with the bottom of rubber boss 12, and rubber boss 12, body of rubber 11 and base 13 are an entirety.
As shown in Figure 3, the annular flat straight section 111 in body of rubber 11 113 to be connected by one section of annular arc section 112 with outside main body, and the intersection of described annular arc section 112 and annular flat straight section 111 is H2 to the distance on the top of base 13.Outside main body, 113 cave inward, and the minimum diameter of recess is D3.And body of rubber 11 below the top of base 13 is very little on the impact of the rigidity of vertical backstop, the body of rubber 11 more than top of base 13 is very large on the impact of the rigidity of vertical backstop.Increase the rigidity that D3 can increase vertical backstop 1, increase the rigidity that H2 can reduce vertical backstop 1; Otherwise, reduce the rigidity that D3 can reduce vertical backstop 1, reduce the rigidity that H2 can increase vertical backstop 1.The preferred value of H2 is the preferred value of 40mm-80mm, D3 is 60mm-70mm.
As shown in Figure 1, Figure 2 and Figure 3, base 13 is gyro-rotor, and base 13 comprises base body 131 and base chimb 132; The thickness of base body 131 upper end is less than the thickness of base body 131 lower end, and the middle part in the outside of base body 131 is provided with base chimb 132, and base chimb 132 protrudes laterally.Base 13 is embedded in body of rubber 11, and be sulfided into an entirety with body of rubber 11, concentrate with the stress of body of rubber 11 junction for reducing base 13, prevent from long-term use procedure, producing gap between base 13 and body of rubber 11, level and smooth circular arc chamfering has all been processed in the corner being embedded in the base 13 in body of rubber 11.
The base 13 of metal is arranged on the lower end of body of rubber 11, when body of rubber 11 upper end is subject to the pressure generation deformation of vertical load and moves down, base 13 can limit body of rubber 11 upper end and move down further, thus plays vertical spacing effect.Therefore the height of adjusting base 13, vertical backstop 1 can be regulated to carry out spacing position, and the preferred value of the height H 5 of base 13 is 30mm-70mm.
Base 13 is embedded in body of rubber 11, and the base body 131 especially above base chimb 132 has extend in body of rubber 11, and the top of base body 131 is H3 to the distance on the top of base chimb 132.The value of H3 is larger, and the rigidity of vertical backstop 1 is larger, that is, increases the height of base 13, especially increases the height of H3, can increase the rigidity of vertical backstop 1.Otherwise reduce the height of base 13, especially reduce the height of H3, can reduce the rigidity of vertical backstop 1, the preferred value of H3 is 10mm-45mm.
Because base 13 is made up of the metal that hardness is large, can play vertical spacing effect, the body of rubber 11 below the top of therefore base body 131 has an impact hardly to the rigidity of vertical backstop 1 and variation rigidity.So injected by the rubber of heat when conveniently manufacturing vertical backstop 1, also in order to reduce the consumptive material of rubber, the midway location bottom body of rubber 11 is provided with a shrinkage pool 114.Although the height H 4 of shrinkage pool 114 has an impact to the rigidity of vertical backstop 1 and variation rigidity hardly, the value of H4 too conference affects the firmness that body of rubber 11 is combined with base 13, and therefore H4 can not be contour with H5, and the preferred value of H4 is 10mm-30mm.
In sum, vertical backstop 1 is by regulating the diameter of body of rubber 11 and rubber boss 12 and height, and the height of adjusting base 13, regulates the rigidity of vertical backstop 1; By regulating the angle between annular flat straight section in body of rubber 11 and horizontal surface, and outside boss 122 with the angle at boss top 121, regulate the variation rigidity of vertical backstop 1; By the height of adjusting base 13, vertical backstop 1 is regulated to carry out spacing position; The vertical load reducing steel spring 2 by regulating the spacing position of the rigidity of vertical backstop 1, variation rigidity and vertical backstop 1 and bear, thus better reduce the metal fatigue that in locomotive operation process, steel spring 2 produces, the more effective steel spring 2 that prevents ruptures.
Embodiment two
As shown in Figure 6, the present embodiment and the main difference of embodiment one are, outside main body, the vertical section of 113 is circular arc protruding laterally, and that is body of rubber 11 becomes outwardly shape.Outside main body, the maximum gauge of high spot is the preferred value of D4, D4 is 80mm-90mm.
Due to the protrusion laterally of the middle part of body of rubber 11, increase the diameter of body of rubber 11 middle part, therefore increase the rigidity of vertical backstop 1.As shown in Figure 7, for embodiment one, the rigidity of the present embodiment is comparatively large when initial, and stiffness curve time initial is also slightly steep.And along with the increase of load, the difference between the stiffness curve of two embodiments is more and more less.The magnitude of load of dissimilar locomotive is also different, and usual embodiment one is in the less locomotive of load, and the present embodiment is used in the larger locomotive of load.
Obviously, under the prerequisite not departing from principle described in the utility model, the some improvement made or modification all should be considered as protection domain of the present utility model.
