Design and Research of New Parking Brake Mechanical Release Device

The technical background,existing problems and potential safety hazard of the parking brake mechanical release device on the urban rail transit vehicle were analyzed.The composition,structural design and functionality of the new parking brake mechanical release device are introduced in detail.The mock-up test and the qualification test on the vehicle demonstrated that the performance of the device meets the specification compliance of being able to operate mechanically release parking brake inside the car as well as outside the car.At the same time,the operation of the new parking brake mechanical release device is monitored by the vehicle monitoring system,which is safer and more reliable.The new parking brake mechanical release device has been produced and applied on the subway vehicles exported to Boston in the United States.The design idea of the new parking brake mechanical release device provides a direction for the design of the urban rail transit vehicles and the railway EMUs in China.
