High-speed train bogie traction motor frame suspension suspension device

Abstract

The invention provides a suspension type suspension device for the traction motor frame of a high-speed train bogie, which is used to suspend the traction motor on the bogie frame. A spring mounting seat is provided on both sides of the beam. The longitudinal beam includes two parallel plates and a vertical plate. A horizontal through hole is arranged on the vertical plate. A vertical safety pin is sleeved inside the horizontal through hole. The vertical safety pin has two The two ends of the vertical safety pin are fixedly connected to the spring mounting seat, and a cylindrical horizontal stopper with an inner diameter larger than the vertical safety pin and an outer diameter larger than the horizontal through hole is respectively sleeved on the two ends of the vertical safety pin, and the horizontal stopper is fixedly connected. On the spring mounting seat, the lateral stopper and the vertical safety pin are sheathed with a traverse spring; when the bogie of the motor car moves laterally, due to the lateral elasticity of the present invention, the action of the driving device lags behind the bogie, which can be extremely fast. Greatly improve the hunting instability speed of the power bogie.

Description

technical field [0001] The invention relates to a high-speed motor train bogie, in particular to a high-speed motor train bogie traction motor frame suspension device with transverse elasticity. Background technique [0002] With the rapid growth of my country's economy, the people's requirements for travel are getting higher and higher, not only for speed, but also for ride comfort, and high-speed railways have emerged as the times require. As of 2015, the mileage of my country's high-speed railway (passenger dedicated line) has exceeded 10,000 kilometers. A key component of the high-speed railway system is the high-speed train. In recent years, my country has developed the CRH series of high-speed EMUs through the strategy of introduction, absorption, digestion and innovation, and independently developed a test train with a speed of 600 kilometers per hour and a speed of 600 kilometers per hour. 350 kilometers of Chinese standard EMUs. Although my country's high-speed EMU...

Problems solved by technology

[0004] There are many shortcomings in the design of traction motor suspension devices for power bogies at home and abroad. First, the design and manufacture of thin leaf springs is difficult and expensive. my country does not have the ability to produce this kind of thin leaf springs; Vertical elasticity, poor vertical dynamics, poor security
