Compensation type stepless adjustment device of empty weight/heavy weight wagon with vibration damping

An adjustment device and compensation technology, applied in transportation and packaging, railway car body parts, railway braking systems, etc., can solve the problems that the air pressure of the brake cylinder cannot be adjusted separately, and cannot solve the deviation and limitation, so as to achieve braking The rate is close to the same, the effect of eliminating inaccurate weight measurement and reducing wheel rubbing accidents

Problems solved by technology

The air pressure of the brake cylinder and the depressurization air cylinder of the freight car empty-load adjustment device that has appeared in recent years cannot be adjusted separately. air pressure
In order to reduce the pressure of the brake cylinder of the empty vehicle, the brake system of the original truck had to be changed to increase the volume of the decompression air cylinder, so the pressure reduction of the brake cylinder of the empty vehicle was limited.
Moreover, the weighing suppression plate used in the previous automatic adjustment device for stepless freight cars can not solve the deviation caused by the vertical vibration of the train body when the train is running. This deviation makes the pressure deviation of the brake cylinder as high as -25%-+25%, which is serious. Affected the effect of "stepless adjustment"

Embodiment Construction

[0026] Compensated truck stepless automatic adjustment device system for empty and heavy trucks with damping and vibration reduction, see attached figure 1 . Dotted line part among the figure is the equipment of former two pressure brake systems. Its composition mainly contains secondary air cylinder 4, brake cylinder 10, step-down air cylinder 16, brake control valve 9, and train pipe 6, and they all needn't refit. This device has only six parts: adjusting valve 12, valve seat suppressing disc support 13, sensing valve control part 14, sensing valve compensating part 15, damping and damping suppressing disc 17 and touch plate 18. Wherein the control part 14 and the compensating part 15 of the sensing valve are integrated and installed on the valve seat bracket 13 . Seat support and suppression disc support are made of precision casting as a whole. The pipeline connection mode is divided into two ways by the brake hole outlet of the brake control valve 9 (referring to the br...

Abstract

The invention relates to a compensated step-less bare weight automatic adjuster of truck with damping vibration attenuation, while the former brake system can not reduce the pressure of brake cylinder significantly. The invention uses the control part 14 and the compensate part 15 of sensing valve to assist the adjusting valve 12 to adjust the pressure of brake cylinder and reduce the pressure of wind cylinder. It can step-less adjust the pressure of brake cylinder from bare weight to heavy weight of truck, without changing the former brake system, to significantly reduce the pressure of brake cylinder. The invention comprises a damping spring recover function, a air damping vibration attenuation, and a brake pressure self-locking weight-detecting restrain disc 17, to completely eliminate the effect on detecting weight by vibration when driving, therefore, the working state of restrain disc and sensing valve will all the same when the truck is braked. The invention can effectively reduce the longitudinal impact and avoid accidence.

Description

technical field [0001] The invention relates to the field of air brakes for railway freight cars, and is an automatic adjustment device for freight car brakes that can automatically adjust the air pressure of a brake cylinder steplessly as the load of the freight cars changes. technical background [0002] The former Soviet Union, Germany, Japan, and the United States all have different types of automatic adjustment devices for empty-loaded vehicles, and the former Soviet Union is the most widely used. These empty-load truck devices are divided into two-stage, multi-stage and stepless automatic adjustments. Some of them have been installed and tried in our country. Because they are not suitable for the objective conditions of Chinese trucks, they are damaged soon after loading and use and are eliminated. Some cannot be matched with the two-pressure direct-acting brake control valve, and it is difficult to popularize. Therefore, the manual two-stage empty-load vehicle convers...
