Embodiment Construction
[0023] The present invention is further described below in conjunction with specific embodiment, and specific embodiment is the further description of the principle of the present invention, does not limit the present invention in any way, and the identical or similar technology of the present invention all does not exceed the scope of protection of the present invention.
[0024] In conjunction with the accompanying drawings.
[0025] As shown in the figure, the connection structure between the bogie and the vehicle includes a car body 4 and a bogie 1. The bogie 1 includes a bolster 2 supported on the wheels. The car body 4 includes a bolster arranged at the bottom of the car body. The beam and the bolster 2 of the bogie 1 are hinged and fixed through the center plate 3 .
[0026] The central disk 3 is an integral structure composed of an upper connecting plate 3-1, a lower rotating disk 3-3 and connecting ears 3-2 on both sides.
[0027] The bolster 2 is provided with perfo...

The invention discloses a connecting structure of a bogie and a vehicle. Comprises a vehicle body and a bogie, wherein the bogie comprises a bolster supported on wheels, the vehicle body comprises a bolster beam arranged at the bottom of the vehicle compartment, and the bolster beam of the vehicle body and the bolster of the bogie are hinged and fixed by a center plate. As that low turntable of the center plate is match with the pillow center plate, the invention does not affect the normal operation performance of the vehicle, in particular the curve passing performance, and the influence of the rigid connection on the operation performance of the vehicle is reduce to the maximum extent; The center plate is convenient to connect with both the bogie and the vehicle body, which can not onlyprovide the angle that the vehicle body is permitted to twist when crossing the curve, but also ensure that no reinforcement measures need to be set when the bogie and the vehicle body are hoisted integrally; The invention has simple structure and is convenient to implement. The bolster and the center plate are processed after being cast and formed so as to ensure the assembling dimension accuracy. The invention has strong adaptability, and can be applied to any gauge, axle load and most types of railway freight car bogies.
Description
technical field [0001] The invention belongs to the field of design and manufacture of railway transportation devices, in particular to the design and manufacture of railway vehicle bogie structures, and in particular to the connection structure between railway freight car bogies and car bodies. Background technique [0002] When the car body and the bogie of a conventional railway vehicle are hoisted and transferred, the car body and the bogie are not fixedly connected, and they will be separated when they are hoisted together, which is not conducive to transportation and subsequent reset. Therefore, it is necessary to design a connection structure that does not separate the car body and the bogie during hoisting and transportation. [0003] Chinese application 201310405208.7 discloses a railway freight car body and bogie hoisting connection device, including an anti-detachment seat arranged on the lower cover plate of the car body bolster, a lock plate arranged on the bogi...
