Abstract

A central pin bush for a bogie traction device is characterized in that two axial through holes are arranged on a middle rubber layer, and a taper angle of an internal tapered face is larger than a self-locking angle of the tapered face. The two axial through holes are arranged on the middle rubber layer, so that variable rigidity of the central pin push can be realized in the longitudinal direction of a track and torsional rigidity of the central pin bush is low, and the taper angle of the internal tapered face is larger than the self-locking angle of tapered face so that a central pin and the central pin bush can be separated from each other conveniently.

Description

A kind of bogie truck draw gear center guide
Technical field
The utility model relates to a kind of bogie truck draw gear center guide.Relate in particular to a kind of track longitudinal direction of realizing and become rigidity, self torsional stiffness is little, easily detachable bogie truck draw gear center guide.
Background technology
The center guide is a metal rubber piece, divides three layers, and interlayer is a rubber layer, inside and outside be 45 steel matter, the draw beam interference fit of outer ring and bogie truck draw gear, inner ring and the center pin cone match that is connected car body.In existing bogie truck draw gear, on the one hand, operating difficulties when installing in order to the locating dowel pin of permanent center guide, center pin and three parts of lower cover causes setup error easily; On the other hand, when car body and bogie truck decomposed, center pin and center guide decomposition difficulty were big; In addition, the radial rigidity of existing center guide is big, brings the temporary impact of center pin in the time of can not cushioning from emergency brake of vehicle and starting effectively.
The utility model content
Technical problem to be solved in the utility model is, the torsional stiffness of reduction center guide is not become flexible to satisfy the king bolt that connects other parts of center pin and draw gear when cancellation draw gear locating dowel pin aftercarriage produces maximum twist with respect to bogie truck; Increase center guide inner ring cone angle, the dismounting difficulty of reduction center pin; The structure of improvement center guide rubber layer brings the ability of center pin temporary impact when making it not only to have enough lateral stiffnesses but also when possessing buffering from emergency brake of vehicle and starting.
For solving the problems of the technologies described above, the utility model provides a kind of bogie truck draw gear center guide, it is characterized in that: middle rubber layer has two axially extending bores, inner ring conical surface cone angle greater than the conical surface from the locking angle.
The utility model is because intermediate rubber layer is opened axial hole, on the one hand, reduced the torsional stiffness of center guide, do not become flexible to satisfy the king bolt that connects other parts of center pin and draw gear when the locating dowel pin aftercarriage produces maximum twist with respect to bogie truck in the cancellation draw gear, bring the ability of center pin temporary impact when on the other hand, making it not only to have enough lateral stiffnesses but also when possessing buffering from emergency brake of vehicle and starting.The increase of inner ring conical surface cone angle has surpassed the conical surface from the locking angle, has reduced the dismounting difficulty of center pin.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cutaway view along A-A line among Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2, the utility model has been opened two axially extending bores at the rubber layer 2 of centre, makes center pin be enclosed within the track longitudinal direction and can realize becoming rigidity, and self torsional stiffness is little; Guide inner ring 3 conical surface cone angles increase and to have surpassed the conical surface from the locking angle, have made things convenient for separating of center pin and center guide, and the 1st, the outer ring.
