Embodiment Construction

[0020] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0021] In order to eliminate or attenuate the resonance source of the transmission shaft of the mechanical anti-skid sensor, that is, to make the angular acceleration of the transmission shaft be zero or tend to zero, the present invention provides a connection device for rail vehicles, such as Figure 1a , Figure 1b and figure 2 As shown, the connecting device 10 is connected between the transmission shaft 21 of the mechanical anti-skid sensor 20 and the wheel axle 31 of the rail vehicle, and it includes a connecting block 11 and an elastic connecting body 12, and the connecting block 11 is slidably connected to the elastic connecting body 12 . The connecting block 11 is fixed on the connecting end of the transmission shaft ...

Abstract

The invention relates to a connecting device for a rail vehicle. The connecting device is connected between a transmission shaft of a mechanical anti-slipping sensor and an axle of the rail vehicle and comprises a connecting block and an elastic connecting body, and the connecting block is connected to the elastic connecting body in a slidable mode. The connecting block is fixed to the connecting end of the transmission shaft, the elastic connecting body is fixed to the connecting end of the axle, and the end face of the connecting end of the elastic connecting body is parallel to the end face of the connecting end of the axle. A channel for the elastic connecting body to penetrate through in a sliding mode is formed in the connecting block, and the sliding friction factor between the channel of the connecting block and the elastic connecting body is smaller than or equal to 0.11. Connection matching between the connecting block and the elastic connecting body is adopted in the connecting device, relative sliding and elastic deformation can be generated, angular speed sudden change caused by eccentric motion of the transmission shaft is relieved, and namely the angular acceleration alpha approaches zero, so that energy is transmitted between the axle and the transmission shaft, and then resonance of the mechanical anti-slipping sensor and other problems are solved.

Description

technical field [0001] The invention relates to an auxiliary device in a rail vehicle running system, in particular to a rail vehicle connection device connected between a transmission shaft of a mechanical anti-skid sensor and a rail vehicle wheel axle. Background technique [0002] The mechanical anti-skid sensor is an auxiliary device used on rail vehicles. It is installed in the running system of the rail vehicle. The mechanical anti-skid sensor has a transmission shaft, which is coaxial with the wheel axle of the rail vehicle through a connecting device when assembled. Connected, the drive shaft is driven by the wheel shaft to rotate synchronously. The function of the mechanical anti-skid sensor is to prevent sliding friction between the wheel and the track. When the rail vehicle runs at a constant speed, the wheel shaft rotates at a constant speed, and the transmission shaft of the mechanical anti-skid sensor also rotates at a constant speed. At this time, the mechani...
