Locomotive brake control system and rail vehicle

Abstract

A locomotive brake control system comprises a brake cylinder pipe, a master air cylinder pipe, a first pressure valve and a primary control unit, wherein that primary control unit control the brake cylinder pipe and the master air cylinder pipe to communicate with each other through the first pressure valve; Also included is a secondary control unit that controls communication between the brake cylinder pipe and the master cylinder pipe via the second pressure valve, the control pressure of the second pressure valve being greater than the control pressure of the first pressure valve. A locomotive brake control system Two-stage braking is provided, and the braking force of two-stage braking is different. In the process of locomotive running, the first-stage braking is generally adopted. Ifthe first-stage braking cannot meet the braking demand of locomotive, the second-stage braking can be adopted, which can increase the braking capacity of locomotive in a short time and ensure the braking safety of locomotive. The invention also discloses a rail vehicle comprising the brake control system of the locomotive.

Description

technical field [0001] The present invention relates to the field of mechanical control, and more specifically relates to a locomotive braking control system and a rail vehicle with the aforementioned locomotive braking control system. Background technique [0002] The brake system of rail locomotives and engineering vehicles is a key component to ensure the safety of rail transportation. The safety, reliability and stability of the brake system are particularly important. Therefore, hidden dangers in the brake system will pose a serious threat to the safety of locomotives. . [0003] At present, when locomotives and engineering vehicles are used as rescue vehicles for vehicles, the rescue vehicle cannot control the braking and relief of the rescued vehicle, and can only realize the marshalling of the entire train (rescue vehicle and rescued vehicle) through the braking and relief capabilities of the rescue vehicle itself. ) braking and release.

Problems solved by technology

[0003] At present, when locomotives and engineering vehicles are used as rescue vehicles for vehicles, the rescue vehicle cannot control the braking and relief of the rescued vehicle, and can only realize the marshalling of the entire train (rescue vehicle and rescued vehicle) through the braking and relief capabilities of the rescue vehicle itself. ) braking and relief

When the weight of the rescued vehicle reaches a certain level and the whole train is on a certain slope, the maximum braking capacity of the rescue vehicle itself may not be able to ensure the safe parking of the whole train on the slope, which will seriously affect the safety of locomotives and engineering vehicles.
