Abstract

The utility model relates to the guide track manufacture technique, particularly a shock absorption track which comprises two or more than two guide tracks which are mutually connected. Gaps are arranged between two adjacent guide tracks. The utility model is characterized in that an included angle of the end surface of each guide track with the length direction is an acute angle; two adjacent end surfaces are mutually parallel. When wheels run to the joint gaps, the wheels and the surfaces of the guide tracks are still kept with contact sections, and empty gaps can not generated. The wheels can stably run to the other guide track from one guide track. The shock and the noises are mitigated. The utility model is helpful for enhancing the service life of the wheels and the life of carriers and track bases on the wheels.

Description

Shock-absorption track

The utility model relates to the guide rail manufacturing technology.

In the prior art, the track of long distance, for example railroad track all is to be spread by the guide rail connection of many fixed length not form, and in construction, considers this phenomenon of expanding with heat and contract with cold that occurs of material when variation of ambient temperature.Appropriate gap is left in the joint of common two guide rails, with the needs that are used to be out of shape.Because the both ends of the surface of every guide rail are vertical with its length direction, therefore its slot direction is parallel with the wheel axis direction, make the wheel of rolling vacancy occur with contacting of guide rail, so when wheel runs to this joint vacancy mouth, produce impact force, cause bigger vibrations and noise, also quickened the wearing and tearing of felly and the early stage damage of whole system simultaneously.

The purpose of this utility model is to overcome above deficiency, by improving slide rail connector structure, makes vehicle operating mild, reduces vibrations and noise.

The purpose of this utility model realizes in the following manner.

Shock-absorption track described in the utility model, include two or two tracks that are interconnected to form with upper rail, be reserved with the gap between two adjacent guide rails, it is characterized in that the end face of every guide rail and the angle of its length direction are acute angle, two adjacent end faces are parallel to each other.This improvement makes the gap direction of reserving between two guide rails and the angle of the wheel axis direction of rolling on guide rail be acute angle, when wheel runs to the place, play movement, wheel surface has remained with guide rail surface and has contacted partly, the vacancy mouth can not occur, thereby wheel is carried out the transition on another root guide rail reposefully from a guide rail.

In order to ensure eliminating the above vacancy mouth, the end face of every guide rail and the angle of its length direction can make one's options according to the width of guide rail surface and the size of gap width, can be determined by following formula particularly:

tga＜b／δ，

In the formula, b is a guide rail upper surface plane width partly, and δ is the gap width that should reserve between two adjacent guide rails.

In the practical engineering application, its δ value can be found from interrelated data, or obtains with known design formulas.

Compared with prior art, the utility model has been eliminated the influence of guide clearance to the driving wheel effectively, vibrations have been alleviated widely, reduced noise, and owing to the impact that has alleviated wheel, reduce the wearing and tearing of wheel external surface, helped prolonging the life-span of wheel application life and whole system.On the other hand, the utility model is implemented simple, does not improve the original product cost.

Be further elaborated below by embodiment and accompanying drawing.

Fig. 1 is two I shape rail connecting interface schematic diagrames.Among the figure, the adjacent face of left rail (1) and right rail (2) is parallel to each other, and δ is the preset clearance width between two one steel rails, and b is a partly width of rail top surface plane.

Fig. 2 is the vertical view of Fig. 1.The α angle is the angle of rail end face and length direction among the figure.

When the utility model was used for general railroad track, its b=46mm was 40 ℃ and under the condition that minimum temperature is laid a railway track to the maximum in the temperature difference, gets δ=18mm according to interrelated data.Then the α angle can be chosen in 0 °＜α＜68 °.α=45 ° for example, angle is moderate, neither can influence the intensity of rail itself.And can eliminate vibrations and noise.
