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.
