Problems solved by technology
However, limited by its own structure, its hand brake ratio is still low, and it is difficult to directly adapt to the braking requirements of heavy axle trucks.
[0005] Therefore, a set of hand brake force amplifying levers must be set on the car body in addition, but this brings great difficulty to the design of the hand brake system. It is impossible to set another set of hand brake force amplification lever on the car body, which greatly reduces the adaptability of the integrated brake device

Embodiment Construction
[0035] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0036] see Figure 1~3 and Figure 12~13 , the integrated braking device for railway wagons with master braking magnification of the present invention is mainly composed of a two-way self-adjusting stroke booster brake cylinder 4, a front brake beam 1 and a rear brake beam 9, a front brake lever 2 and a rear brake lever 8. Front brake chain 3 and rear brake chain 5, brake shoe 10, and hand brake lever 11 are formed. For the specific structure and working principle of the two-way self-adjusting stroke booster brake cylinder 4, refer to the Chinese utility model patent whose publication number is CN202251575U. The structural relationship between the components is described in detail as follows:
[0037] The front brake beam 1 and the rear brake beam 9 are symmetrically arranged on both sides of the bogie bolster 13, and the middle part of the f...

The invention discloses a high-hand-braking-magnification rail wagon integrated brake device, which mainly solves the weaknesses of the existing brake device that the hand braking magnification is low, and the brake requirement of a large-axle-weight wagon cannot be met. The high-hand-braking-magnification rail wagon integrated brake device comprises a two-directional self-adjusting stroke reinforcement increasing brake cylinder, a front brake beam, a rear brake beam, a front brake lever, a rear brake lever, a front brake chain, a rear brake chain, a brake shoe and a hand braking lever, and the high-hand-braking-magnification rail wagon integrated brake device is characterized in that one end of the hand braking lever is connected with a car body hand brake device, and the other end of the hand braking lever is connected with an adjusting part of the two-directional self-adjusting stroke reinforcement increasing brake cylinder. The high-hand-braking-magnification rail wagon integrated brake device is not only simple and compact in structure, convenient and easy to assemble and capable of optimizing the car body structure, effectively reducing the weight of the vehicle and improving the carrying capacity of the vehicle, but also high in hand braking magnification, stable and reliable in performance and capable of omitting a hand braking force magnification lever on the car body and improving the adaptability of the integrated brake device.
Description
technical field [0001] The invention relates to the technical field of railway wagon braking, in particular to an integrated braking device for railway wagons with a high hand braking ratio that is suitable for being installed on a bogie. Background technique [0002] In order to meet the needs of the rapid development of the national economy, the domestic railway transportation industry is also developing rapidly. The axle load and speed of railway freight cars continue to increase. The stability, reliability, braking capacity, braking efficiency and maintenance of railway freight car braking devices Requirements such as maintenance performance are also increasing. [0003] The brake cylinder and the brake shoe clearance adjustment mechanism in the traditional railway freight car brake device are arranged separately, and the brake cylinder and the brake shoe clearance adjustment mechanism are connected by a series of transmission parts such as levers and connecting rods.
