摘要:
Railway three-axle, three-motor locomotive trucks are provided with a bolster spring-supported on the truck frame for lateral and vertical movement and having a central opening to accommodate the middle axle motor while minimizing the over-all height of the truck, a plurality of vertically nonyielding body-support bearing elements on the bolster spaced apart transversely and longitudinally of the truck to prevent tipping of the bolster relative to the body, a swivel connection between the body on the bolster, and a draft connection between the bolster and truck frame at a level at least as low as the axles to provide low-level transmission of traction forces between the truck frame and bolster and thereby reduce axle-to-axle load transference and thereby improve adhesion.
