Five-shaft steering bogie base braking device

Abstract

The invention relates to a five-shaft steering bogie base braking device, which is characterized by comprising five wheel shafts, wherein a support is respectively arranged between two adjacent wheel shafts at two sides; each support is provided with two brake beam safety chains, one safety chain is connected with an external brake beam and the other safety chain is connected with an internal brake beam; a supporting column is arranged between the internal and external brake beams, two ends of the supporting column are respectively provided with a set of brake block, and each brake block is clamped and adhere to the outer margin of a wheel adjacent to the brake block; the support on one side is provided with an external arc lever and an internal arc lever; a connecting rod is in pinned joint with the top of the external arc lever, and the other end of the connecting rod is connected to the support; two ends of a lower tension rod are connected with the bottoms of the internal and external arc levers; the support on the other side is provided with a floating lever and an internal arc lever; a brake tension bar is in pinned joint with the top of the floating lever, and two ends of another lower tension rod are connected with the bottom of the floating lever and the bottom of the internal arc lever; and two ends of an upper tension rod are connected with the tops of the two internal arc levers. The five-shaft steering bogie base braking device can be widely used in brake systems of multi-shaft steering bogie railway vehicles.

Description

technical field [0001] The invention relates to a brake device, in particular to a foundation brake device for a five-axle bogie of a railway freight car. Background technique [0002] In order to realize the planning of newly built or reconstructed railways with a speed of 200 kilometers per hour, the development of the TJ165 bridge erecting machine meets the erection requirements of the new 2201T bridge, and can erect various other domestic railway concrete bridges to meet the erection of 32 meters in the tunnel. bridge construction requirements. The TJ165 bridge erecting machine is composed of three parts: the main engine, the auxiliary machine, and the inverted gantry crane. Since the traditional 25-ton axle load bogies such as Zhuan K6 are difficult to meet the requirements, it is considered through economic analysis that the combination of one set of five-axle bogies and two sets of Zhuan K4 bogies can well meet the requirements of TJ165 bridge erection. However, the...

Problems solved by technology

Since the traditional 25-ton axle load bogies such as Zhuan K6 are difficult to meet the requirements, it is considered through economic analysis that the combination of one set of five-axle bogies and two sets of Zhuan K4 bogies can well meet the requirements of TJ165 bridge erection. However, there is no foundation braking device for five-axle bogies at present.
