The invention discloses a high-speed train bogie traction motor frame suspension-type suspension device used for suspending a traction motor on a bogie frame. The high-speed train bogie traction motor frame suspension-type suspension device comprises bogie frame cross beams, vertical suspenders, and a motor mounting rack; the two sides of each of two longitudinal beams of the motor mounting rack are provided with one spring mounting base respectively; each longitudinal beam comprises two parallel plates and a vertical plate; each vertical plate is provided with a transverse through hole; a vertical safety pin is sleeved by a corresponding transverse through hole; the two ends of each vertical safety pin are fixedly connected with a corresponding spring mounting base; the outer parts of the two ends of each vertical safety pin are sleeved with a lateral stopping block respectively, wherein the inner diameter of the lateral stopping block is larger than the diameter of the vertical safety pin, and the outer diameter of the lateral stopping block is larger than the diameter of the transverse through hole; each lateral stopping block is fixedly arranged on a corresponding spring mounting base; the outer part of each lateral stopping block and a corresponding vertical safety pin are sleeved with a laterally moving spring. When a train bogie moves laterally, the high-speed train bogie traction motor frame suspension-type suspension device possesses lateral elasticity, the action of a driving device lags behind that of the train bogie, so that hunting instability speed of the power bogie is increased greatly.
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...
