Articulation device for locomotive and vehicle connection

Abstract

The invention provides a hinged device for the mutual connection of locomotives and vehicles. The joint end mounting seat is provided with a horizontal mounting hole, which is in interference fit with the hinged rubber joint. There is a boss on the shaft; the traction end mounting seat is provided with a U-shaped installation groove for installing the hinged rubber joint mandrel. The top of the U-shaped installation groove is detachably installed with a pressing block. The bottom surface of the pressing block can be aligned with the plane above the mandrel. Cooperate to prevent the mandrel from rotating; a ring-shaped mandrel stopper is provided, which can abut and cooperate with the semi-circular boss on the inner side of the U-shaped installation groove and the boss on the mandrel. The bottom surface of the pressure block cooperates with the plane above the mandrel to prevent the hinged rubber joint mandrel from rotating, the mandrel stopper restricts the movement of the mandrel in the horizontal direction, and there is no impact and sliding friction between the parts, ensuring that the traction end mounting seat The mutual movement with the joint end mount is entirely borne by the deformation of the inner rubber of the articulated rubber joint.

Description

technical field [0001] The invention relates to the technical field of rail vehicle connection devices, in particular to a hinged device for connection of rolling stock. Background technique [0002] The train is generally composed of multiple carriages connected. If a hinged connection is used, movements such as nodding, shaking, and rolling will occur at the joint of the two carriages during the operation of the vehicle. These movements will impose a large load on the hinged rubber joints. Therefore, the articulated rubber joint is a key part of the entire articulated device. Some articulated traction devices use simple vertical positioning when positioning the rubber joints, and the friction force generated between the contact surfaces through the vertical bolt pre-tightening force limits the movement of the rubber joints. This positioning method requires the use of large bolts. Provide sufficient preload, resulting in insufficient layout space, and cannot ensure the hor...

AI Technical Summary

Problems solved by technology

Some articulated traction devices use simple vertical positioning when positioning the rubber joints, and the friction force generated between the contact surfaces through the vertical bolt pre-tightening force limits the movement of the rubber joints. This positioning method requires the use of large bolts. Provide enough pre-tightening force, resulting in insufficient layout space, and cannot ensure the horizontal positioning of the rubber joints when the car is dropped

[0003] There are also some articulated traction devices that use the "eight-shaped" positioning structure, and two eight-shaped planes are cut out on the mandrel for positioning and installation, but the diameter of the mandrel is relatively thick, which affects the overall size of the rubber joint.

Although this structure has good vertical guiding ability when getting off the car, it cannot guarantee horizontal alignment
