Abstract

The utility model relates to a novel rubber stack localizer of a rail vehicle bogie, which comprises a metal jacket, an outer layer rubber sleeve, a metal distance sleeve, a middle layer rubber sleeve, an inner layer rubber sleeve and a metal inner housing core axle which are fixedly connected from the inner part to the outer part, wherein, the thickness proportional range of the outer layer rubber sleeve, the middle layer rubber sleeve and the inner layer rubber sleeve are 1:(1.2 to 1.4):(1.6 to 1.8). The thickness of the three layers of rubber sleeves of the novel rubber stack localizer is gradually thickened, thereby the stress of the three layers of rubber sleeves are basically and equally distributed, and the identical fatigue lives are realized, serious stress concentration can not occur under the effects of the longitudinal bearing, the transverse bearing and the vertical bearing, the matching for rigidity can also be realized, the mechanical performance requirement of the bogie is met, the service life is long, and the traveling requirement that the vehicle moves more than 800,000 kilometers can be met.

Description

Rail vehicle steering frame novel rubber stack positioner

Technical field

The utility model relates to a kind of damping means of rail vehicle truck, particularly a kind of rail vehicle steering frame novel rubber stack positioner.

Background technology

Rubber stack positioner is as the caoutchouc elasticity vibration-damped component of rail vehicle truck, its composition comprises the metal-coating of captive joint from outside to inside, the outer layer rubber cover, the metal spacer, the middle level rubber coating, the metal spacer, the internal layer rubber coating, the inner metal sleeve mandrel, outside the existing rubber stack positioner, in, the height of interior three layers of rubber coating increases progressively successively, but thickness is identical, the major defect of its existence is: bearing under the effect of bogie three-way reverse load, the load-carrying capacity of its internal layer rubber coating is starkly lower than the middle level rubber coating, the load-carrying capacity of middle level rubber coating is starkly lower than the outer layer rubber cover again, thereby cause because of the excessive crackle that occurs of internal layer rubber coating carrying, cause the whole damage of rubber stack positioner, shorten service life, half that have only 800,000 kilometers of bogie truck expectation of service lifes is less than.

Summary of the invention

Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and a kind of rail vehicle steering frame novel rubber stack positioner of long service life is provided.

The technical scheme that its technical matters that solves the utility model adopts is as follows: a kind of rail vehicle steering frame novel rubber stack positioner, its composition comprises metal-coating, outer layer rubber cover, metal spacer, middle level rubber coating, metal spacer, internal layer rubber coating, the inner metal sleeve mandrel of captive joint from outside to inside, wherein, outward,, the height of interior three layers of rubber coating increases progressively successively, it is characterized in that described outer, in, the thickness of interior three layers of rubber coating increases progressively successively, proportional range is 1: (1.2-1.4): (1.6-1.8).The beneficial effects of the utility model are as follows: under the prerequisite that the gross thickness of three layers of rubber coating of rubber stack positioner maintains the original state substantially, outward, in, the thickness of interior three layers of rubber coating increases progressively successively, reach the equal stress designing requirement, make the distribution of stress of three layers of rubber coating impartial substantially, thereby has identical fatigue life, vertically, laterally and under the vertical carrying effect can not produce serious stress concentration, and can realize Rigidity Matching, satisfy the requirement of bogie truck dynamic performance, long service life can satisfy rail vehicle truck and move driving requirement more than 800,000 kilometers.

Description of drawings

Fig. 1 is the utility model integral structure elevation profile scheme drawing.

Number in the figure is illustrated as: 1-inner metal sleeve mandrel; 2-internal layer rubber coating; 3-metal spacer; 4-middle level rubber coating; 5 metal spacers; 6 outer layer rubber covers; 7 metal-coatings.

The specific embodiment

With reference to the accompanying drawings and in conjunction with example the utility model is described in further detail.But the utility model is not limited to given example.

As shown in Figure 1, the utility model rail vehicle steering frame novel rubber stack positioner, caoutchouc elasticity vibration-damped component as the 209HS bogie truck, its composition comprises the metal-coating 7 of captive joint from outside to inside, outer layer rubber cover 6, metal spacer 5, middle level rubber coating 4, metal spacer 3, internal layer rubber coating 2, inner metal sleeve mandrel 1, wherein, outward, in, interior three layers of

rubber coating

6,4,2 height increases progressively successively, under the prerequisite that the gross thickness of three layers of rubber coating maintains the original state substantially, outward, in, interior three layers of

rubber coating

6,4,2 thickness also increases progressively successively, proportional range is 1: (1.2-1.4): (1.6-1.8), for example, outward, in, the ratio of the thickness of interior three layers of rubber coating is 1: 1.3: 1.7, and the gross thickness of three layers of rubber coating is about 42-45cm among the embodiment.
