Abstract
The utility model relates to a horizontal control lever sleeve. A control level inner sleeve, a rubber layer and a control level outer sleeve are jacketed in sequence outside the outer ring of a control lever. The control lever inner sleeve and the control lever outer sleeve are fixedly connected with each other through the rubber sulfurization function of the rubber layer. The control lever inner sleeve has a structure that the outer ring made of metal material slightly protrudes outwards. The control lever outer sleeve has a structure that the inner ring made of metal material slightly protrudes inwards and the protruding surface is in the wave form. The thickness of the center of the rubber layer is less than the thickness of the edge thereof. The utility model has the advantages that the sulfurization thermal stress of the horizontal control lever sleeve can be uniformly eliminated, the required prestress can be provided in the operating process, and the service life is long.
Description
Technical field
The utility model relates to a kind of bar cover.A kind of horizontal control stalk cover of bogie truck particularly.
Background technology
The horizontal control stalk cover of bogie truck is installed on the lateral connecting rod on the bogie truck, in train travelling process especially when train is crossed bend, can play assist train and turn to the while also can play the phenomenon of crawling that prevents in the vehicle operating process, therefore to train operation quality and safe in operation important influence.What the horizontal control stalk cover of old structure adopted is three jacket structures, though this structure can satisfy its static properties requirement, and can eliminate horizontal control stalk to a certain extent and overlap the thermal stress of vulcanizing, but can only eliminate thermal stress unevenly, another tangible deficiency is that it has caused rubber in-to-in unbalanced stress to spare property, and this will seriously influence the service life of this bar cover.
Summary of the invention
The purpose of this utility model is the deficiency at the horizontal control stalk cover of old structure, provides a kind of and can evenly eliminate horizontal control stalk cover heat of vulcanization stress, can provide prestress required in the use, the horizontal control stalk cover of long service life.
The technical solution of the utility model is: a kind of horizontal control stalk cover is set with cover, rubber layer and control stalk overcoat in the control stalk successively in proper order on its control stalk outer ring.Cover and control stalk overcoat are integral by the vulcanization of rubber of rubber layer is affixed in the control stalk.
The shape and structure that cover slightly outwards protrudes for the outer ring of being made by metallic material in the described control stalk.
Described control stalk overcoat omits to shape and structure projecting inward and the projecting surface undulate for the inner ring of being made by metallic material.
The thickness of described rubber layer center is less than the thickness of edge.
The utility model has obtained laterally stress, the strain of control stalk cover in the vehicle operating process according to the thermal stress deformation that calculates, test obtains the sulfuration of horizontal control stalk cover according to calculating the vehicle actual operation parameters.The inner ring that has adopted overcoat is slightly to structure projecting inward and the projecting surface undulate, and this structure has not only been eliminated horizontal control stalk cover heat of vulcanization stress, and appropriate pre _ stress is provided.
The utility model is adjusted the cavity shape of overcoat, the outer shape of interior cover after the amount of contraction of having determined rubber, so just can adjust the static properties of horizontal control stalk cover preferably.
The utility model has the advantages that providing a kind of can evenly eliminate horizontal control stalk cover heat of vulcanization stress, can provide prestress required in the use, the horizontal control stalk cover of long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A-A of the utility model Fig. 1 is to cutaway view.
Among the figure 1, the control stalk overcoat, 2, inner ring, 3, rubber layer, 4, the outer ring, 5, cover in the control stalk, 6, control stalk.
The specific embodiment
As shown in Figure 1 and Figure 2: a kind of horizontal control stalk cover is set with cover 5, rubber layer 3 and control stalk overcoat 1 in the control stalk successively in proper order on its control stalk 6 outer rings.Cover 5 and control stalk overcoat 1 are integral by the vulcanization of rubber of rubber layer 3 is affixed in the control stalk.
The shape and structure that cover 5 slightly outwards protrudes for the outer ring of being made by metallic material in the described control stalk.
Described control stalk overcoat 1 omits to shape and structure projecting inward and the projecting surface undulate for the inner ring of being made by metallic material.
The thickness of described rubber layer 3 centers is less than the thickness of edge.
Claims (4)
1, a kind of horizontal control stalk cover is characterized in that: be set with cover, rubber layer and control stalk overcoat in the control stalk on its control stalk outer ring successively in proper order, cover and control stalk overcoat are integral by the vulcanization of rubber of rubber layer is affixed in the control stalk.
