A new traction-balanced driving vehicle steering in complicated cross country terrains was developed to improve the synchronous driving vehicle steering in complicated terrains low traction efficiency.

Adding the NC machine' s speeding to finish machining, we use traction drive we made the special hilt for adding speed and high - speed cutting.

In the light of the specific characteristics of structure of traction drive speed -raising system, its structure is modified and resistance method is introduced to measure the lubrication film, besides, computer is used to collect and analyze data.

In the light of developed large gear ratio traction drive speed -increasing mechanism design, we take advantage of international general finite element analysis software- ANSYS to do finite element analysis to contact unit of traction drive speed - increasing mechanism, ascertain rational magnitude of interference of interference joints.

Effects of adoption of AC drive technology for traction power of rolling stocks on the traction power supply system is analyzed.

Based on analysis on the trend of structural regulation of national energy resources, the necessities of using electric power supply as traction power for railways are expounded.

The article analyzes the status quo and the existing problems of the depot stations in the whole railway system and describes the influence of the development of traction power on layout and design of depot stations.
