Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] Such as figure 1 Shown, the present invention comprises a positioning rotating arm 1, an axle box body 2, a frame positioning rotating arm seat 3, a framework 4, an axle box spring 5, an axle box rubber pad composition 6 and a one-way axle box oil Pressure shock absorber 7.

[0015] One end of the positioning arm 1 is fixed on the bearing seat of the axle box 2 through bolts, and the other end is connected with the frame positioning arm seat 3 through an elastic node to form a hinged arm. Since the connection point of the articulated arm is an elastic node, no wear can be achieved, and different longitudinal and lateral positioning stiffnesses can be realized, which can effectively restrain the bogie from snaking. Axlebox spring 5 is arranged between the top of axlebox body 2 and frame 4, and axlebox rubber pad composition 6 is added between ...

Abstract

The invention relates to a jib-type axle box positioning device for a bogie. The jib-type axle box positioning device is characterized by comprising a positioning jib, an axle box body, a framework positioning jib seat, an axle box spring, an axle box rubber pad assembly, a unidirectional axle box oil damper and a framework, wherein one end of the positioning jib is fixed on a bearing seat of the axle box body through bolts, and the other end of the positioning jib is connected with the framework positioning jib seat through elastic nodes, so as to form an articulated jib; the axle box spring is arranged between the top of the axle box body and the framework, and the axle box rubber pad assembly is additionally arranged between the axle box body and the axle box spring; and the end part of the positioning jib and that of the framework are connected through the unidirectional axle box oil damper. The jib-type axle box positioning device can favorably serve an elastic positioning function, has stable properties, avoids abrasiveness, ensures the security and the stationarity of the vehicle running at a high speed, effectively prevents the bogie from snaking movement, and can be extensively applied to various wagons.

Description

technical field [0001] The invention relates to an axle box positioning device, in particular to a bogie pivot arm type axle box positioning device which can be used for 160km / h railway freight cars. Background technique [0002] The current passenger car bogies above 160km / h have stable operation and good comfort. However, the structure of passenger car bogies cannot be directly used due to the characteristics of passenger cars with low self-weight and low load, which are opposite to the characteristics of freight trains with small self-weight and heavy load. For truck bogies. The key to improving the critical speed of express freight trains lies in the positioning structure of the wheelset of the bogie. The axle box positioning device of the bogie is a mechanism that constrains the relative movement between the wheel set and the frame. Compared with the axle box of the passenger car bogie, the axle box of the truck bogie can meet the stability of the vehicle when it is em...
