Embodiment Construction

[0017] like figure 1 As shown, the rail vehicle traction device with elastic stop function in this embodiment has a vertically arranged pressure plate 2 and a back plate 4, an elastic element 3 is arranged between the pressure plate 2 and the back plate 4, and the back plate 4 is used to be fixed on the On the side of the bogie facing the corbel, the outer side of the pressure plate 2 is provided with a friction plate 1 for resisting the corbel of the rail vehicle from the longitudinal direction. The center of the pressure plate 2 protrudes toward the back plate, and the protrusion is provided with a screw hole. The center of the back plate is opened and a backing plate 5 is provided inside. The compression of the elastic element is realized by screwing the hexagon socket compression bolt 6 into the screw hole.

[0018] The friction plate 1 is made of synthetic materials such as nylon and aramid reinforced composite materials with good wear resistance. The pressing plate 2, t...

Abstract

The invention relates to a traction device with the elastic stopping block function for a rail vehicle. The traction device is provided with a pressing plate and a back plate which are vertically arranged, and an elastic element is arranged between the pressing plate and the back plate; and the back plate is used for being fixed in the side where a bogie faces toward a sleeper beam, and a friction plate is arranged on the outer side face of the pressing plate and is used for abutting against the sleeper beam of the rail vehicle from the longitudinal direction. According to the traction device with the elastic stopping block function for the rail vehicle, in the running process of the rail vehicle, traction force is transmitted to the rail vehicle to ensure normal running of the rail vehicle; due to the fact that an elastic stopping block is provided with the elastic element, longitudinal impact generated in the starting and braking process of the rail vehicle can be eliminated, and comfort and safety of riding of passengers are improved; and meanwhile, due to the fact that a vehicle body bottom frame makes contact with the elastic stopping block elastically and frequently, snaking operation of the rail vehicle on a straightway can be effectively restrained, and safety of the rail vehicle is ensured.

Description

technical field [0001] The present invention is an elastic stopper for transmitting longitudinal traction force between rail vehicle body and bogie and restricting the vehicle from snaking in a straight line, belonging to a device for traction between rail vehicle bogie and car body and limiting vehicle snaking motion technology field. Background technique [0002] In the design process of rail vehicles, the longitudinal force is generally transmitted through the central traction device to ensure that the vehicle runs along the laid track. At present, the commonly used central traction devices include traction rubber pile traction, single traction rod traction and double traction rod traction. These three common traction devices are installed in the center of the bogie and connected to the body bolster or traction beam to pull the rail vehicle along the track. The structure of the traditional traction device is complicated, and daily inspection and maintenance are difficult...
