摘要： An outboard journal railway truck includes a journal bearing having an auxiliary structure with resilient elements attached thereto for carrying devices which are maintained in a fixed wheel to rail relationship. A primary suspension system having longitudinal, lateral and vertical springs is connected between the journal bearing housing and a side frame. The secondary suspension system includes a steering beam for maintaining vertical springs in vertical positions during movement of the beam with respect to the side frames of the truck and for transmitting the load from a car body directly to the side frames of the truck.

摘要： A pair of adjustment plates are disposed below a mechanical spring which supports a car body. At least one of the adjustment plates include spaced stepped portions to engage a portion of the other plate with the stepped portion engaged determining the height of the car. When the car load is removed from the springs, the relative positions of the plates may be selectively changed to adjust the height of the car body. A shock absorber is connected inside the mechanical spring and removable through the adjustment plates.

摘要： A primary suspension spring disposed between a wheel journal and a railway truck side frame includes top and bottom elastomeric members which form a ring around the journal. Both members include a relatively large cut-away portion towards their centers to provide soft vertical and longitudinal spring rates for a car body. Relatively small amounts of elastomeric material are disposed longitudinally towards the front and rear of the large cut-away portions towards the tangents of the wheel journal.

摘要： A primary suspension system is disposed between a wheel journal bearing and a side frame of a railway truck to minimize acceleration forces from being transmitted from a wheel axle unit to a car body. A pair of elastomeric members form a ring clamped around the journal bearing and are bonded to multiple outer plates disposed in different planes. Relatively low spring rates are provided when one set of outer multiple plates are operative with relatively high spring rates being provided when the elastomeric members are compressed and the inner multiple plates become operative.
