Shock absorbing shaft seat device for motor suspension

The invention provides a shock absorbing shaft seat device for motor suspension and belongs to the field of a suspending device for a motor of a rail vehicle. The shock absorbing shaft seat device comprises a rubber node, an eccentric wheel axle sleeve seat, a vertical bearing lifting seat and a vertical shock absorbing pin mechanism, wherein the rubber node acts as a horizontal elastic shaft component; and the eccentric wheel axle sleeve seat comprises an axle sleeve, a bearing lifting seat connecting plate and a rubber node shaft sleeve which are formed integrally. The shock absorbing shaftseat device provided by the invention makes a motor housing base plate obtain symmetric stability mechanically structurally, makes the stress distribution between an axle and the motor housing base plate be more reasonable, also achieves the effects of optimizing the structural balance performance, reducing fatigue losses of materials and prolonging the service life of equipment, and makes the parameter range of the value
