Abstract
The utility model discloses a hinging connection structure of the auto top end and the upper hinge of the light rail vehicle of aluminum alloy car body and low floor, comprising a connecting bolt with high strength, an upper hinging connection body, an auto end upper structure of the auto body. The utility model is characterized in that: the hinging connection structure also comprises an upper hinging seat. One end of the upper hinging seat is connected with the auto top part of the auto body by welding, and the other end is connected with the hinged body by the high-strength bolt. The utility model strengthens the end part structure of the auto body, improves the stress situation of the whole end part of the auto body, achieves the integral stress of the aluminum alloy auto body of end part whether the longitudinal pressure or longitudinal tension is exposed on the end part of the auto body, and solves the problem that the tearing accident of end part of auto body is easy to happen in the hinged connection structure of the upper hinge of an existing auto body.
Description
Technical field
The utility model belongs to trolley coach vehicle structure technical field, relates on a kind of car body hinge pivotally attached connection structure, particularly a kind of aluminum alloy bodywork low-floor light rail vehicle roof end and the last hinge structure that is articulated and connected.
Background technology
It is stressed bigger to cut with scissors especially the elasticity hinge in the end connection structure of low-floor light rail vehicle.Last hinge articulated body adopts the high strength carbon steel casting usually, and the aluminium section bar of roof end welding structural entity good rigidity but local strength a little less than.Because the thickness of aluminium section bar is little, the surperficial accident of tearing easily when stressed of aluminium section bar itself.How to solve the difficult problem that is connected to become of end aluminium alloy structure and high strength carbon steel casting.
The utility model summary of the invention
The utility model discloses a kind of aluminum alloy bodywork low-floor light rail vehicle roof end and the last hinge structure that is articulated and connected, the car body end construction is strengthened, improve car body end force-bearing situation, to solve the problems such as accident that easily tear the car body end in the hinge pivotally attached connection structure on the existing car body.
The utility model comprise high-strength tie bolt, on cut with scissors articulated body, car body car end topside, it is characterized in that: also comprise hinged seat, last hinged seat one end and car body roof end are by being welded together, and the other end is connected by high strength bolt realization and articulated body.
By making the welding respectively of hinged seat and car body at two vertical plane surfacies of roof and car end, not only realized being connected of maximum range of last hinged seat and car body, realized the reinforcement of hinged seat simultaneously to the end construction of car body own.In addition, large-area welding line structure has also guaranteed being connected of hinged seat and the end construction of car body own.
The utility model has improved the force-bearing situation of whole locomotive body end, makes no matter the car body end is when being subjected to longitudinal pressure or longitudinal pulling force, has all realized the whole stressed of end aluminum alloy bodywork.

The specific embodiment
Below be an embodiment of the present utility model.
As shown in Figure 1 and Figure 2: the utility model embodiment comprises hinge articulated body 3, aluminum alloy bodywork car end topside 4 on high-strength tie bolt 2, the carbon steel structure, it is characterized in that: also comprise hinged seat 1 on a kind of aluminum alloy, hinged seat 1 one ends and car body car end topside 4 are by being welded to connect on the aluminum alloy, and the other end is fastenedly connected hinge articulated body 3 on hinged seat on the aluminum alloy 1 and the carbon steel structure with high strength bolt.
By making hinged seat 1 and car body on the aluminum alloy in being connected respectively of two vertical plane surfacies of roof and car end, not only realized being connected of maximum range of last hinged seat and car body, realized the reinforcement of hinged seat simultaneously to the end construction of car body own.In addition, large-area welding line structure has also guaranteed being connected of hinged seat and the end construction of car body own.
The utility model has improved the force-bearing situation of whole locomotive body end, makes no matter the car body end is when being subjected to longitudinal pressure or longitudinal pulling force, has all realized the whole stressed of end aluminum alloy bodywork.
