Railway vehicle coupler stop structure, traction beam and railway vehicle
A rail vehicle and traction beam technology, applied in the field of rail transit, can solve problems such as collision between the coupler device and the end face of the traction beam, affect the service life of the traction beam end plate and coupler, and damage the painted surface, so as to improve the reliability and durability of use Safety, avoid occupying the space of the car body, and ensure the effect of maintenance-free

Embodiment 1
[0045] In a typical embodiment of the present invention, refer to figure 1As shown, a rail vehicle coupler stop structure is installed on the traction beam end plate 1 on both sides of the coupler. The coupler stop structure 10 includes a bent bracket 2, and a buffer member is installed on one side of the bracket 2, and the buffer member faces the coupler. It is arranged so that when the coupler swings laterally to the end plate on one side of the draw beam, it is aligned with the buffer member on that side;
[0046] In some examples, coupler stop structures are installed at the end plates of the traction beam on both sides of the coupler to avoid collisions between the coupler and the end plates of the traction beam on both sides during lateral swing.
[0047] Further, as a preferred solution, the bracket is an integral structural member; in some other examples, the bracket can be formed by connecting multiple parts, which can be welded or connected by other means.

Embodiment 2
[0064] The difference between this embodiment and Embodiment 1 is that the bracket 2 is T-shaped, and when the bracket 2 is installed on the end plate of the traction beam, the T-shaped bracket is installed horizontally, that is, the T-shaped bracket is rotated to set an angle and then installed on the end plate of the traction beam. One side of the traction beam is fixedly connected with the end plate of the traction beam, and the other side is provided with a buffer. The length of the buffer can be shorter or longer than the length of the side where the bracket is connected to it. Preferably, the length of the buffer is the same as that of the side where the bracket is connected to it. are the same length.
[0065] Of course, it is easy to understand that the T-shaped bracket can be a symmetrical or asymmetrical T-shaped bracket, and the asymmetrical T-shaped bracket reduces the occupation of the vehicle body space as much as possible.

Embodiment 3
[0070] refer to Figure 4-Figure 6 As shown, the present invention also provides a rail vehicle traction beam, including a traction beam body, the traction beam body has end plates on both sides of the coupler, and the end plates on both sides are provided with the first or second embodiment. A rail vehicle coupler stop structure 10, the installation position of a rail vehicle coupler stop structure on the end plate of the traction beam is located at 1 / 4-1 / 3 or 2 / 3-3 / 3 of the length direction of the end plate of the traction beam 4, considering the distance between the end plates on both sides of the traction beam and the installation position of the coupler, the installation position of the coupler stop structure can effectively cooperate with the coupler, which can effectively ensure that the coupler 9 is in the same position as the buffer member 4 during the lateral swing process. Positive touch, avoid the hard knock that coupler 9 and drawbeam cause.
