Domestic some enterprise starts to adopt small electrical locomotive to replace diesel locomotive to carry out joining tank under stove at present, this electric locomotive small volume, low cost of manufacture, simple to operate, easy to maintenance, can realize remote frequency variable speed governing as required, deeply be subject to user's welcome, have very large development prospect.
Diesel locomotive is that the gaseous tension that produces by Air compressor itself promotes brake lever and drives interlock contracting brake mechanism to carry out wind to control moving when stopping brake, and the body construction limited space of small electrical locomotive is difficult to adopt wind brake equipment, and the braking force of general electrical equipment drg not enough, with regard to a kind of novel brake equipment of needs, solve stopping brake problem like this.
Summary of the invention
The object of the present invention is to provide a kind of electro-hydraulic brake device of electric locomotive, the parts such as the voltage transformer that omission volume is larger and Air compressor and air receiver, improve the reliability and stability of electric locomotive braking, solve the stopping brake problem of the lower small electrical locomotive of large load.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of electro-hydraulic brake device of electric locomotive, comprise brake lever and interlock contracting brake mechanism, described brake lever is connected with dual control connecting lever through connecting rod, the piston end of dual control connecting lever difference linking springs seat and Electrohydraulic push rod, the structure of described dual control connecting lever comprises suspension bracket, universal driving shaft, single head connecting lever and double end connecting lever, single head connecting lever universal driving shaft relative to double end connecting lever is fixedly connected with, the motion end of single head connecting lever is connected with brake lever through connecting rod, the drive end one of double end connecting lever is connected with the piston end of Electrohydraulic push rod, the drive end two of double end connecting lever is connected with spring perch, between spring perch and the vehicle frame of horizontal direction, be provided with spring, suspension bracket one end and universal driving shaft are hinged, the suspension bracket other end is connected with the chassis frame at top, the vehicle frame of Electrohydraulic push rod body and horizontal direction is hinged.
Angle α between described single head connecting lever and double end connecting lever is 15 °～18 °.
The composite structure spring that described spring is comprised of outer spring and interior spring.
Compared with prior art, the invention has the beneficial effects as follows: cancelled the facilities such as voltage transformer and Air compressor and air receiver, structure is simpler, and hydraulic operation is more convenient.Be suitable for multiple small-sized railway electric locomotive vehicle, there is promotion prospect.Reduce maintenance cost, obviously improved brake efficiency, reliability and stability simultaneously.
