The invention discloses a rail wagon
bogie single-stage shaft housing hanging and positioning device. The rail wagon
bogie single-stage shaft housing hanging and positioning device comprises a shaft housing, a vertical hydraulic buffer, spring guide pillars, steel circular springs, rubber-
metal pad locators and hoisting check blocks, wherein the vertical hydraulic buffer is arranged between the top of the shaft housing and a side frame of a framework
assembly; the spring guide pillars, the steel circular springs and the rubber-
metal pad locators are arranged between the upper surfaces of spring bearing platforms on the two sides of the shaft housing and the bottom of the framework
assembly; the hoisting check blocks are arranged below the spring bearing platforms on the two sides of the shaft housing. The two-stage threaded connection method of the spring guide pillars is of an
integrated design, so that the structure is simple and compact, the performance is reliable, stable positioning performance is guaranteed, the requirements for different positioning stiffness in the vertical direction, longitudinal direction and the transverse direction are met, the
unsprung mass can be reduced, wheeltrack dynamic force is lowered, and wheeltrack abrasion is reduced; an
infrared shaft temperature detection hole is formed in the bottom of a
saddle surface of the shaft housing, so that the shortcoming that an
infrared thermometry technology cannot be adopted for an existing rail wagon
bogie single-stage shaft housing in the line operation process is overcome, the bearing temperature of a rail wagon in an operating state can be detected in real time, a
hot box fault caused by detection omission can be avoided, and
rail transportation safety is guaranteed.
