In the figure: 1-a first closed cavity; 2-hanging a mounting plate; 3-a second closed cavity; 4-thread block stops; 5-a third transverse rib; 6-a second transverse rib; 7-a third transverse rib; 8-lap joint; 9-plug-in connector.
Detailed Description
The utility model is further described below in connection with specific preferred embodiments, but it is not intended to limit the scope of the utility model.
For convenience of description, the relative positional relationship of the components, such as: the descriptions of the upper, lower, left, right, etc. are described according to the layout directions of the drawings in the specification, and do not limit the structure of the present patent.
Referring to fig. 1, an embodiment of a side beam profile for a railway vehicle chassis according to the present utility model includes an integrally formed side beam body of an aluminum alloy closed profile, wherein an outer side wall of the side beam body has an arc structure that is folded inwards from a roof to a bottom. According to the load condition and stress distribution of the vehicle body structure, the whole edge beam body is arranged in unequal thickness, namely the thickness of each rib plate of the edge beam body in each direction is unequal in the profile structure of the edge beam body, so that the structure is light in weight and optimal in design under the condition of meeting the strength requirement of the edge beam. In addition, the boundary beam body section structure effectively integrates all functional interfaces, improves the interface integration level, and can meet the installation requirements of all equipment of a vehicle chassis after machining the boundary beam section without welding special installation seats.
Specifically, the inside integrated into one piece heavy equipment installation interface of this boundary beam body, heavy equipment installation interface includes two continuous first closed die cavity 1. The first closed cavity 1 is a through long cavity arranged along the length direction of the side beam, and the specific cross section size of the first closed cavity 1 is 42mmx38mm. The bottom of the first closed cavity 1 is machined to form a heavy equipment mounting hole (not shown) for mounting heavy equipment such as a transformer. The first closed cavity 1 is used for installing screw blocks required for installing heavy equipment such as transformers and the like. When the heavy equipment is installed, the connecting bolts of the heavy equipment are connected with the threaded blocks positioned in the first closed cavity 1 through the heavy equipment installation holes. The heavy equipment installation hole is preferably a waist-shaped hole. In order to ensure the strength of the first closed cavity 1 and to ensure the convenience of installation of the screw blocks, a first transverse rib 7 is arranged above the first closed cavity 1. The structure of the first closed cavity 1 and the rib plates around the first closed cavity can meet the requirement of installing heavy equipment such as transformers (more than 5 t), and solves the problem that the heavy equipment cannot be hung in the traditional chassis side beam hanging mode. The mounting structure does not need to weld a special mounting seat structure, so that the welding quantity of the vehicle body is reduced, and the fatigue and stress concentration of welding seams are avoided.
The inner side of the side beam body is also provided with a hanging mounting plate 2 for mounting other lower-weight underframe equipment except a transformer. In order to strengthen the intensity of the suspension mounting plate 2, a third transverse rib 5 is arranged in the cavity of the boundary beam body connected with the suspension mounting plate 2 and corresponds to the suspension mounting plate 2, and the third transverse rib 5 is aligned and connected with the suspension mounting plate 2, so that the intensity of the suspension mounting plate 2 is greatly increased.
The equipment cabin installation interface is arranged at the lower part of the boundary beam body and comprises a second closed cavity 3, and the section size of the specific second closed cavity 3 is 40.5mm X30mm. The second closed cavity 3 is used for providing a mounting interface for the equipment compartment. The bottom of the second closed cavity 3 is machined to form a row of key-shaped holes for installation of the equipment compartment. In the second closed cavity 3, a screw block stop 4 is provided. In order to reduce the weight of the side beam body to the greatest extent, the thread block stop 4 is realized by arranging a small transverse rib in the second closed cavity 3, and the small transverse rib is as small as possible, and in the embodiment, the specific size of the thread block stop 4 is 10mmX3mm. The purpose of setting the thread block stop 4 is to limit the thread block required by equipment cabin installation, so that the site operation is convenient.
The upper part of the side beam body is provided with a plug connector 9 for connecting with the side wall. The inner side of the side beam body is also provided with a lap joint 8 for connection with the underframe floor.
While the utility model has been described with reference to certain preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the utility model. Therefore, any simple modification, equivalent variation and modification of the above embodiments according to the technical substance of the present utility model shall fall within the scope of the technical solution of the present utility model.
