Abstract
The utility model discloses a secondary four-fulcrum suspension structure for a multi-bogie railway vehicle, which comprises a suspension frame. The lower surface of the suspension frame is supported through rubber springs, wherein the suspension frame is connected with the rubber springs through an air spring supporting seat; the upper part of the suspension frame is provided with a vertical upper stop catch; the supporting seat is arranged at the bottoms of the rubber springs; the air spring supporting seat is inverted U-shaped; the air spring supporting seat is provided with ports for being connected with a vehicle body through bolts or rivets; the Shore hardness of rubber of each rubber spring is 39; each rubber spring is formed by connecting five groups of rubber springs in series; each group of rubber spring comprises 9 layers; and on each layer, four rubber springs are connected in parallel. The secondary four-fulcrum suspension structure has the beneficial effects that the secondary four-fulcrum suspension structure is practical and has a low production cost; the problems of transverse stability and excessive transverse displacement of the multi-bogie railway vehicle are effectively solved; and the secondary four-fulcrum suspension structure is safer.
Description
Technical field
It is four fulcrum suspended structures that the utility model relates to a kind of multi-steering frame rail road vehicle two.
Background technology
The guideway vehicle of operation adopts two bogie truck supporting way substantially at present, this mode advantage is promptly easier by level curve and the relative multi-steering frame of vertical curve, but shortcoming is also very outstanding: wheel load is bigger relatively in the high speed train utilization, wheel-rail impact severity at a high speed, wheel-rail wear is serious, for guaranteeing the vehicle operating performance, just must often carry out Xuan and repair polishing the wheel rail, the rail wheel life is shorter; For heavy-duty vehicle, increase bogie truck quantity, under identical load-carrying, can reduce the average wheel load-carrying too, also help reducing the application force between the wheel track, thereby reduce wheel-rail wear, prolong the wheel track life-span; In addition, in same axis heavily down, can increase load-carrying.Can adopt multi-steering frame vehicle to overcome the relevant issues of two truck cars thus.In order to manufacture and design multi-steering frame rail road vehicle, also be a requisite link as the design of the secondary suspension system of one of crucial mechanical part of running part.When adopting the vehicle structure that supports more than two bogie trucks, use existing pure air bellow or cylindrical coil spring just to be subjected to great limitation, air bellow that bigger cross travel is simple and high round steel spring and other pure spring mode that occur at present all can't realize.
The utility model content
Technical problem to be solved in the utility model is at the deficiencies in the prior art, and it is four fulcrum suspended structures that a kind of later-model multi-steering frame rail road vehicle two is provided.To achieve these goals, the measure taked of the utility model:
A kind of multi-steering frame rail road vehicle two is four fulcrum suspended structures, comprises the suspension frame, and described suspension frame supports below by rubber spring, wherein, is connected by the air bellow supporting base between suspension frame and the rubber spring, and suspension frame top is equipped with the vertical backstop that goes up; The bottom of described rubber spring is equipped with supporting base;
Described air bellow supporting base is an inverted U type, and the air bellow supporting base is provided with bolt or rivet connects the interface that car body is used;
The Shore hardness of the rubber of described each rubber spring is 39;
Described rubber spring is connected by 5 groups of India-rubber springs, and every group has 9 layers, and every layer has 4 India-rubber spring parallel connections.
The beneficial effects of the utility model: practicality, productive costs is low, efficiently solves multi-steering frame rail road lateral stability of cars problem and cross travel problems of too, and is safer.

The specific embodiment
A kind of multi-steering frame rail road vehicle two is four fulcrum suspended structures, comprise suspension frame 9, described suspension frame 9 supports below by rubber spring 8, wherein, be connected by air bellow supporting base 6 between suspension frame 9 and the rubber spring 8, suspension frame 9 tops are equipped with the vertical backstop 5 that goes up.The bottom of described rubber spring 8 is equipped with supporting base 7, and this suspended structure is installed in orbit, the cross travel of rubber spring 8 energy actv. control guideway vehicles; Described air bellow supporting base 6 is an inverted U type, and air bellow supporting base 6 is provided with bolt or rivet connects the interface that car body is used, and installs easy to connect; The Shore hardness of the rubber of described each rubber spring 8 is 39; Described rubber spring 8 is connected by 5 groups of India-rubber springs, and every group has 9 layers, and every layer has 4 India-rubber spring parallel connections, and India-rubber spring series connection and the rubber spring that combines 8 in parallel make rail vehicle transversal move and have stability more, thereby realizes the purpose of this utility model.
Those skilled in the art's simple change and replacement in this area all are within the protection domain of the present utility model.
