Problems solved by technology

A bogie integrated brake device installs the brake cylinder on the bolster. Its disadvantage is that many installation accessories are welded on the bolster, and the force on the bolster is complicated, which affects the reliability of the bolster, which is the main force-bearing part of the vehicle. , and its degree of integration is low
Another type of bogie integrated brake device installs the brake cylinder on the brake beam. Its disadvantage is that the force of the brake beam is poor, so that the reliability of vehicle braking has not yet passed the test.

Embodiment Construction

[0033] Such as figure 1 As shown, the railway freight car bogie booster integrated braking device provided by the embodiment of the present invention includes a front brake beam 1, a front brake lever 2, a front brake chain 3, a two-way self-adjusting stroke booster brake cylinder 4, a rear Brake chain 5, rear brake lever 8, rear brake beam 9, brake shoe 10.

[0034] Wherein, the front brake beam 1 and the rear brake beam 9 are in an isosceles triangle structure, symmetrically arranged on the bogie bolster 21 (see Figure 7 ) on both sides. A strut 6 is arranged on the front brake beam 1 and the rear brake beam 9, and the strut 6 is located on the perpendicular line of the above-mentioned isosceles triangle. The front brake beam 1 and the rear brake beam 9 designed in this way are stable and reliable in structure and evenly distributed in force. The left and right ends of front brake beam 1 and rear brake beam 9 are fixedly equipped with slide block 7 (see figure 2 ). Sl...

Abstract

The invention discloses an integrated brake device for bogie of rail wagon, which comprises a front brake beam (1), a front brake lever (2), a front brake chain (3), a bi-directional self-regulating stroke force-increasing brake cylinder (4), a rear brake chain (5), a rear brake lever (8), a rear brake beam (9) and a brake shoe (10). The integrated brake device for bogie of rail wagon provided in the invention is simple and compact in structure and convenient and easy to assemble, the integrated brake device for bogie of rail wagon reduces self weight of the vehicle effectively and improves loading capacity of the vehicle.

Description

technical field [0001] The invention relates to the technical field of railway freight car braking, in particular to an integrated braking device for a railway freight car bogie suitable for being installed on a bogie. Background technique [0002] Traditional lever brake devices have been widely used in domestic freight cars, and provide reliable braking performance guarantee for freight cars. The requirements for reliability, braking efficiency, integration and maintenance performance are getting higher and higher. [0003] The transmission parts of the lever brake device are partly installed on the car body and partly installed on the bogie. Its structure is relatively complicated and loose, and it has the following defects: [0004] First, this type of brake device contains a series of levers, push rods and pull rods, which are easily worn or damaged during vehicle operation and braking, thereby greatly increasing maintenance costs and workload. [0005] Second, this ...
