Description
Technical field
The present invention relates to locomotive technology, particularly relate to a kind of locomotive elastic bolster guide and bogie truck.
Background technology
In existing locomotive, backstop of shaking the head mostly is designed to the structure of rigid limit, no matter be on locomotive car body or on truck frame, the structure of backstop of shaking the head is all steel plate or bloom, when locomotive generation yaw motion exceedes allowed band, be welded on shake the head baffle plate and the backstop rigid collision of shaking the head be welded on truck frame on locomotive car body, play position-limiting action.
Although the structure of backstop of shaking the head existing is simple, and also can play position-limiting action, but also have some limitations: locomotive in orbit middle yaw motion is very common, and existing stop configurations of shaking the head frequently rigid collision will occur in spacing process, reduce the traveling comfort of locomotive operation; It is all very inconvenient to install, dismantle and adjust.
Summary of the invention
The object of the invention is to, for above-mentioned existing backstop be rigid collision cause locomotive operation traveling comfort difference and install, dismounting and adjustment inconvenience problem, a kind of locomotive elastic bolster guide is proposed, increase flexible buffer, effectively prevent the rigid collision between backstop, and then improve the traveling comfort of locomotive; And locomotive elastic bolster guide of the present invention is convenient to install, dismantle and adjustment, maintainability is good.
For achieving the above object, the technical solution used in the present invention is: a kind of locomotive elastic bolster guide, comprises bolt, mounting cup and elastic element, and described mounting cup is the cavity with certain space, one end open; Described elastic element one end is fixed on the bottom surface of cavity, and the other end of described elastic element stretches out mounting cup from cavity hatch; Described cavity bottom surface is provided with two or more through hole.The length that elastic element stretches out cavity should meet two and treat deformation length necessary between stop element, and the length that namely elastic element stretches out cavity should ensure that two are treated conventional relative displacement between stop element.
Further, this locomotive elastic bolster guide also comprises adjusting pad, described adjusting pad is one or more, concrete quantity is selected according to two parts spacings to be blocked, described adjusting pad is provided with the through hole matched with cavity bottom surface through hole, described adjusting pad is arranged on the side that cavity bottom surface deviates from elastic element.
Further, described elastic element is rubber element.
Further, described rubber element and the sulfuration of cavity bottom surface are fixed.
Further, described elastic element stretches out one end of mounting cup is frustum.
Another object of the present invention, also disclose a kind of bogie truck, comprise bogie truck body and described locomotive elastic bolster guide, described bogie truck body is provided with the through hole matched with cavity bottom surface through hole, described locomotive elastic bolster guide is bolted on the side near car body on bogie truck body, realizes locomotive car body and bogie truck (bogie truck is shaken the head) limit function together with the backstop of car body corresponding site.Be appreciated that the connection of described bogie truck body and locomotive elastic bolster guide also can adopt other attaching partss to connect.
In like manner, described locomotive elastic bolster guide can also be directly installed on the side of locomotive car body near bogie truck, realize locomotive car body and bogie truck (bogie truck is shaken the head) limit function together with the backstop of bogie truck corresponding site.
Locomotive elastic bolster guide of the present invention and bogie structure simple, reasonable, compact, have the following advantages compared with existing rigidity backstop: locomotive elastic bolster guide of the present invention adopts elastic element, effectively avoid rigid collision, increase flexible buffer, improve traveling comfort and the stationarity of locomotive operation; Be convenient to install, dismantle and adjustment, maintainability is good.And because of structure of the present invention simple, be convenient to implement, compare the expense that existing rigidity backstop increases little.

Detailed description of the invention
Embodiment 1
Fig. 1 is the using state schematic diagram of locomotive elastic bolster guide of the present invention.
Present embodiment discloses a kind of locomotive elastic bolster guide, as depicted in figs. 1 and 2, this locomotive elastic bolster guide comprises bolt 4, mounting cup 2 and elastic element 1, and this mounting cup 2 is for having the cavity of certain space, one end open; Described elastic element 1 one end is fixed on the bottom surface of cavity, and the other end of described elastic element 1 stretches out mounting cup 2 from cavity hatch, and one end that described elastic element stretches out mounting cup is frustum; Described cavity bottom surface is provided with four through holes.This elastic element is rubber element, and rubber element and the sulfuration of cavity bottom surface are fixed.The shape of above-mentioned cavity includes but not limited to cylindrical and rectangle, and in the present embodiment, cavity adopts the circular cylindrical cavity of one end open, and this cavity has the effect of spacing (amount of compression of restriction elastic element) and guiding (controlling the compression direction of elastic element).
In addition, this locomotive elastic bolster guide also comprises adjusting pad 3, this adjusting pad 3 is felt pan, the requirement of two, border parts spacing to be blocked factually, can suitably choose pad number, this adjusting pad is provided with the through hole matched with cavity bottom surface through hole, this adjusting pad is arranged on the side that cavity bottom surface deviates from elastic element.Be appreciated that described adjusting pad can also select rubber pad, resin mat.
Locomotive elastic bolster guide of the present invention is provided with flexible buffer, effectively can avoid the rigid collision at two positions to be blocked, improves traveling comfort and the stationarity of locomotive operation; It is convenient to install, dismantle and adjustment, and maintainability is good.
Embodiment 2
Fig. 3 is the using state schematic diagram of locomotive elastic bolster guide of the present invention.
Present embodiment discloses a kind of bogie truck, this bogie truck comprises bogie truck body 5 and the locomotive elastic bolster guide disclosed in embodiment 1, this bogie truck body 5 is provided with the through hole matched with cavity bottom surface through hole, bolt 4 is located in bogie truck body 5 through hole and cavity bottom surface through hole, and fixed by nut, make described locomotive elastic bolster guide be fixed on the side of close car body 6 on bogie truck body 5.
