Detailed Description
The following detailed description of the preferred embodiments will be made with reference to the accompanying drawings.
As shown in fig. 1-3, the present invention provides a multi-azimuth buffer for a railway vehicle bogie, wherein the multi-azimuth buffer 1 is arranged on a bogie 2, is in an inverted T-shaped structure, and comprises three hydraulic telescopic rods, one end of each hydraulic telescopic rod is connected to one position, and each hydraulic telescopic rod is a vertical hydraulic telescopic rod 11 and two horizontal hydraulic telescopic rods 12, the other end of each vertical hydraulic telescopic rod 11 is connected to a vehicle body underframe for buffering vertical vibration from a vehicle body, and the other ends of the two horizontal hydraulic telescopic rods 12 are transversely arranged on the bogie 2 for buffering transverse vibration from the vehicle body. Like this, can cushion the transverse vibration and the vertical vibration that come from the automobile body with the help of vertical hydraulic telescoping rod 11 and horizontal hydraulic telescoping rod 12, can carry out diversified buffering to the horizontal hunting and the upper and lower vibration of automobile body, improved and taken comfort level and driving safety nature, can also further reduce the damage of vertical vibration to the secondary spring on the bogie simultaneously, improve secondary spring's life.
Specifically, the coupler 13 is arranged at a position where the vertical hydraulic telescopic rod 11 and the two horizontal hydraulic telescopic rods 12 are connected, the surface of the coupler 13 is connected with one end of the vertical hydraulic telescopic rod 11, and two ends of the coupler 13 are respectively matched with one ends of the two horizontal hydraulic telescopic rods 12, so that the three hydraulic telescopic rods can be conveniently connected together by means of the coupler 13, particularly, the two horizontal hydraulic telescopic rods 12 are detached and connected, in addition, the vertical hydraulic telescopic rod 11 and the coupler 13 can be of an integrated structure, and transmission and consumption of vertical vibration and transverse vibration are facilitated.
