Embodiment Construction
[0034] The core of the present invention is to provide a railway vehicle and its vehicle connection device. The vehicle connection device has a relatively large force transmission area, which can greatly improve the reliability of the vehicle connection device in the process of force transmission, and further improve the safety of the vehicle running.
[0035] After a lot of research, it has been confirmed that the main reason for the fracture of the shaft 31' in the vehicle connection device in the prior art is that the load transmission between the concave joint 2' and the convex joint 1' depends on the connection between the shaft 31' and the concave joint 2'. The shaft 31' is arranged horizontally in the axial direction, so that the contact surface between the shaft 31' and the concave joint 2' is relatively small during the force transmission process, and when a relatively large force load is transmitted, the shaft The part of the handle 31' is subject to excessive pressur...

The invention discloses a railway vehicle and a vehicle connecting device thereof. The vehicle connecting device includes a convex joint and a concave joint. The convex joint is provided with a ball head, the spherical surface of the ball head is convex downward, and the concave joint is provided with a ball seat, The ball seat is machined with a ball socket matched with the ball head, and the opening of the ball socket is upward; the vehicle connection device further includes a limiting member for confining the ball head in the ball socket; the vehicle connection device in this paper has tensile load, compression The load and vertical load are transmitted through the spherical mating surface between the ball head and the ball socket, that is, the force transmission surface formed by the spherical mating surface. Uniform transmission, and even if the vehicle connection device is in a relatively large corner state, the spherical contact can ensure that the bearing surface has a relatively large contact area, avoid the phenomenon of bearing breakage caused by excessive local load, ensure the safety of vehicle operation and improve the bearing. service life.
Description
technical field [0001] The invention relates to the technical field of vehicle connection, in particular to a railway vehicle and a vehicle connection device thereof. Background technique [0002] The vehicle connection device is an important part of the railway freight car, and its main function is to connect two adjacent trains and transmit the force between the vehicles. A specific form of a typical vehicle connection device in the prior art is given below. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a vehicle connection device in the prior art. [0004] figure 1 The vehicle connecting device can realize that two adjacent trains are jointly supported on the same bogie, allowing certain corners in the horizontal and vertical directions between each other, and the outer ends of the vehicles are supported on independent bogies in a conventional manner. The vehicle connection device includes a male joint 1' assembly, a female join...
