Embodiment Construction

[0039] The present invention will be further described below in conjunction with accompanying drawing.

[0040] figure 1 and 2 A coupling 100 according to one embodiment of the invention is shown. like figure 1 and 2 As shown, the coupling 100 includes two elastic body connecting devices 90, and the two elastic body connecting devices 90 are arranged opposite to each other. Specifically, each elastomer connection device 90 has a spider 1 . like image 3 As shown, the spider 1 has a spider main body 11 and a plurality of first arm end bosses 12 . The spider main body 11 is cylindrical. The boss 12 at the first arm end is fixedly connected with the spider main body 11 and extends radially outward. A plurality of bosses 12 at the first arm end are arranged at intervals in the circumferential direction. Fan-shaped elastic elements 2 are correspondingly arranged on each first arm end boss 12 , and the plurality of elastic elements are circumferentially spaced apart.

Abstract

The invention provides a coupling for rail vehicles and a method for adjusting rigidity thereof. The coupling comprises two relatively arranged elastic body connecting devices, each elastic body connecting device is provided with a star shaped frame, and the star shaped frame is provided with a star shaped frame main body and a plurality of first arm end bosses which are fixedly connected with thestar shaped frame main body and are arranged in a circumferential interval manner, and the first arm end boss is correspondingly provided with a fan-shaped circumferential spacing elastic element. The structure of the coupling is very compact, the reliability is high and it is convenient to install and maintain.

Description

technical field [0001] The invention relates to the technical field of locomotive vehicle transmission systems, in particular to a rail vehicle coupling and a method for adjusting its stiffness. Background technique [0002] In a mechanical system, different mechanical transmission devices require certain components to be connected to transmit motion and torque to the rear. [0003] Couplings have good displacement compensation performance and the ability to reduce vibration and noise in mechanical systems, so they are often used in the connection of mechanical transmission equipment widely used in vehicles, ships, lifting, chemical, logistics and other industries. Especially in the field of rail transit, the requirements for the locomotive and vehicle transmission system are extremely high, and the size of the transmission space is strictly limited. As a key component of the transmission system, the locomotive coupling is required to be able to improve and optimize the axia...
