A railway vehicle and a joint connector thereof

Abstract

The invention provides a joint connector of a railway vehicle. While a longitudinal gap is compensated for, the rotation flexibility is not influenced. The joint connector comprises a concave joint provided with an installing cavity and a convex joint with the rear end articulated in the installing cavity; a slave plate is arranged between the concave joint and the convex joint; the front end surface of the slave plate and the rear end surface of the convex joint are spherical surfaces matched with each other. The joint connector also comprises an elastic member; the front end of the elastic member can be pressed against the slave plate and the rear end can be pressed against the concave joint, so that the longitudinal gap can be compensated for through the front-back deformation thereof. The elastic deformation of the elastic member can compensate for different longitudinal gaps and further guarantee the reliability of load transfer; the deformation of the elastic member varies with the working condition of the joint connector flexibly, so that a certain rotation freedom is provided for the joint connector and the rotation flexibility is not influenced; the flexibility of the elastic member enables the elastic member to compensate for longitudinal gaps in the tensile load transfer process.

Description

technical field [0001] The present invention relates to the technical field of railway vehicles, in particular to a joint connector for railway vehicles and the same. Background technique [0002] The joint connector is a connecting device between vehicles, which is used to connect adjacent vehicles. For railway vehicles, the use of joint connectors enables adjacent vehicles to be jointly supported on a bogie, thereby saving the number of bogies and reducing the quality of the train. . [0003] Please refer to figure 1 , figure 1 It is a typical joint connector structure in the prior art. [0004] The joint connector (a joint connector provided by American ASF company) includes male joint 10, female joint 20, king pin 30, center pin 40, pin block 50, slave plate 60, wedge block 70, ball ring 80 and tee 90 etc. [0005] One end of the male joint 10 facing the female joint 20 forms a connecting end, and the female joint 20 has an installation cavity 201 for accommodating ...

Problems solved by technology

[0016] More importantly, the wedge is used to realize the compensation of the wear gap. After the wear occurs, the wedge will automatically fall to compensate the gap, and when the position of the wedge drops, it will affect the rotation flexibility of the joint connector, which will cause failure

[0017] Therefore, in view of the above technical problems, it is urgent to provide a joint connector for railway vehicles to avoid inflexible rotation due to clearance compensation
