Problems solved by technology
Due to the two-axis and one-side braking, and the influence of the structure of the electric locomotive, the size of the brake handwheel and the ratio of the brake lever are restricted, and the braking force of the entire system is also restricted, so that the braking distance is long or cannot reach the desired value. Parking braking force is required, which affects the safety of electric locomotives
Therefore, the traditional mechanical braking system cannot meet the braking and parking braking requirements of medium-tonnage electric locomotives

Description
technical field [0001] The invention relates to a mechanical braking system of a narrow-gauge electric locomotive. Background technique [0002] Affected by mining technology, narrow-gauge industrial and mining electric locomotives have been in the research and development stage of small tonnage. With the improvement of mining technology in recent years and the development of urban tunnel construction, the market demand for narrow-gauge industrial and mining electric locomotives has begun to develop to medium tonnage. In order to ensure the safety of electric locomotives and improve the reliability of electric locomotive parking brakes, The structure of the mechanical braking system of the parking brake needs to be improved urgently. [0003] The traditional mechanical braking system of narrow-gauge industrial and mining electric locomotives uses dual-axis and one-side braking. The main parts include brake handwheel, brake trapezoidal thread pair, brake lever system, thread...
