Abstract
The utility model relates to a pneumatic control unit for an urban streetcar brake system, which comprises an air storage cylinder, an analog conversion valve, an emergency electromagnetic valve, an empty and load valve, a relay valve and a brake cylinder which are sequentially connected with an air pipe, wherein the emergency electromagnetic valve is connected with the air storage cylinder through the air pipe, the relay valve is connected with the air storage cylinder through the air pipe, the empty and load valve is connected with an air spring through a mean valve, and pressure sensors are arranged on the air pipe. The pneumatic control unit for the urban streetcar brake system is highly accurate and stable in brake force control, brake forces at each brake level are quite stable, and the brake forces at the same brake level during braking and releasing are the same.
Description
Technical field
The utility model relates to a kind of braking force control system of electric car, particularly a kind of air operated control unit of city railroad electric car brake system.
Background technology
Take a broad view of each modernized big city, the world, invariably to develop urban track traffic for basing oneself upon originally.Combining through track traffic between urban track traffic and city, trunk railway passenger traffic, highway passenger transportation, harbour sea-freight, air transportation, form the convenient big traffic networks that should go, is the modernized pattern of traffic greatly, also is the developing direction of China.
In the city rail traffic vehicle; Light rail vehicles such as tramway train are that braking, alleviation are handled the most frequent; Manipulation will braked and alleviate to often every time at a distance from several seconds continuously; And, to try to achieve very short (emergency stopping distance 30m when the Dalian tramway train requires initial speed at brake application 30km/h) to stopping distance for can This vehicle stops frequently, this just requires brake system to have very high sensitivity and the idling braking time of lacking very much.Simultaneously, tramway train adopts the composite brakig mode, closes deceleration and stopping performance so will have good empty Electricity Federation.Simultaneously; Perfect subsequent use brake measure must be arranged; Because tramway train generally all is to adorn a cover braking control system,, just mean that " owning " brake system breaks down in case break down; Therefore must have perfect subsequent use brake measure to guarantee to stop, and the design of air operated control unit is the core of total system.The NABCO brake system of Japan's development at present; The retrostage braking force that has has sudden change, as 3 grades and 5 grades of glancing impacts two kinds of braking forces is arranged, the glancing impact and when alleviating from 7 grades to 1 grade from 1 grade to 7 grades; Braking force with one-level has obvious difference, and the stability of system is had very big influence.
Thereby I am directed against the characteristics of China's city railroad electric car, have researched and developed a kind of city railroad electric car brake system air operated control unit.
The utility model content
The purpose of the utility model is to provide a kind of brake-power control accuracy and stable strong city railroad electric car brake system air operated control unit.
The technical scheme of the utility model is: a kind of city railroad electric car brake system air operated control unit; Described air operated control unit comprises storage reservoir, analog-converted valve, urgent electromagnetic valve, empty and load brake regulator, relay valve and the brake cylinder that joins successively with airduct; Urgent electromagnetic valve joins through airduct and storage reservoir; Relay valve joins through airduct and storage reservoir, and empty and load brake regulator joins through average valve and air bellow; Airduct is provided with pressure sensor.
Preferably: be provided with pressure switch between described urgent electromagnetic valve and the empty and load brake regulator.
Preferably: described pressure sensor is provided with two, on the airduct between relay valve and the brake cylinder and on the airduct between empty and load brake regulator and the average valve.
The beneficial effect of the utility model is: the accuracy of the utility model brake-power control is high with stability, and the braking force of each retrostage is all very stable, and the braking force of same retrostage also is identical in braking and the alleviation process.
