Abstract

The invention discloses a two-axle bogie of an electric locomotive with the 30-ton axle weight. The two-axle bogie is of a two-axle structure and is mainly composed of two wheel set axle box assemblies, two driving units, a framework, four primary suspension devices, a secondary suspension device, a traction device, two motor suspension devices, two braking devices and four tread cleaning devices. According to the improved design of the bogie, the reasonable traction mode and the best suspension parameter configuration are adopted, the heavy-load locomotive can achieve the best adhesion utilization rate and have the good curve negotiating performance, the reliable requirement is met, the power capacity and the traction capacity of the locomotive are developed to the greatest extent, the comprehensive performance of the locomotive is optimized, the running safety, smoothness and comfort indexes are good, the two-axle bogie can be used for greatly improving the carrying capacity of a railway, a research and development platform for the bogie of the electric freight locomotive with the large axle weight, a relevant test system and a relevant standard system are built, and the technical gap for the electric locomotive with the large axle weight is filled in.

Description

technical field [0001] The invention relates to the technical field of railway electric locomotive bogies, in particular to a two-axle bogie for railway electric locomotives with an axle load of 30 tons, which is suitable for railway heavy-duty freight electric locomotives. Background technique [0002] Heavy-duty transportation is the development direction of the world's railway freight. Heavy-duty freight locomotives with an axle load of about 30 tons have been used abroad, such as in North America, Australia, South Africa, Sweden, Brazil and other countries and regions. The axle load of the high-power freight IORE double-section electric locomotive produced by Bombardier and used in the northern Scandinavian mine railway line is 25 / 30 tons. EMD, GE and other companies have successively developed series of locomotives with large axle loads such as GF6C with an axle load of 29.9 tons, AC6000 with an axle load of 32 tons, SD80MAC with an axle load of 30 tons, and SD90MAC wit...
