Problems solved by technology

However, due to the frictional resistance of the sliders as they slide in the side frame runners, this can adversely affect the braking and release of the vehicle
[0003] In addition, due to the difference between foreign boundaries and domestic boundaries, the existing domestic foundation braking devices can no longer meet the requirements of railway freight car bogies with foreign non-standard gauge railway boundaries.

Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 1 As shown, the present invention proposes a foundation braking device for a railway freight car bogie, which includes two brake beams 1, two pairs of brake levers 2, 3, four brake shoes 4, and two fixed lever fulcrums 5 , two pull-down rods 6 and a connecting beam 7. Wherein, two brake beams form 1 and are arranged in parallel and symmetrically.

[0019] Each brake beam assembly 1 includes a brake beam frame 11, a brake shoe holder 12 is fastened to both ends of the brake beam frame 11, and two pillars are fastened to one side of the brake beam frame 11 at intervals. One end of 13 (such as figure 2 shown). The four brake shoes 4 are fastened to the four brake shoe holders 12 respectively.

[0020] The two pull-down rods 6 are arranged in parallel at intervals, one end of the two pull-down rods 6 is hinged to the bottom of ...

Abstract

The invention relates to a foundation braking device for a railway wagon bogie. The foundation braking device is characterized in that two brake beam assemblies, two pairs of brake levers, four brake shoes, two fixing lever fulcrums, two pull-down rods and a connecting beam are included; the brake beam assemblies are symmetrically arranged in parallel, and each brake beam assemble comprises a brake beam frame, wherein the two ends of the brake beam frame are each connected with a brake shoe holder in a fastened mode, each brake shoe holder is connected with a U-shaped swing rod through a through groove, and the opening ends of the swing rods are provided with installing holes; one side of each brake beam frame is connected with one ends of two support columns in a spaced and fastened mode, and the four brake shoes are connected to the four brake shoe holders respectively in a fastened mode; the pull-down rods are arranged in parallel in a spaced mode, one ends of the pull-down rods are hinged to the bottom ends of the first pair of the brake levers, the other ends of the pull-down rods are hinged to the bottom ends of the second pair of the brake levers, the upper ends of the first pair of the brake levers are hinged to fixing lever fulcrum supports arranged on a swing bolster through one fixing lever fulcrum, the upper end of the second pair of the brake levers are hinged to the two ends of the connecting beam, and the middle of the connecting beam is connected with a brake pull rod in a fastened mode.

Description

technical field [0001] The invention relates to a foundation braking device for a railway freight car bogie, and belongs to the technical field of rail vehicle braking. Background technique [0002] The structure and performance of the foundation braking device can directly affect the driving safety of railway vehicles. The standard gauge (1435 mm) railway wagon foundation braking device in the prior art generally adopts a single pull-rod brake and a single middle pull-rod brake of a single-side chute, and relies on the slide block at the end of the brake beam to form the end. Sliding in the frame chute, that is, one end of the lower rod or the middle rod is fixed on the bolster, and the brake lever forms the basic braking device to provide braking force for the bogie. However, due to the frictional resistance created by the sliders as they slide in the side frame runners, this can adversely affect the braking and release of the vehicle. [0003] In addition, because the f...
