专利汇可以提供Railway car steering bogies专利检索，专利查询，专利分析的服务。并且The undercarriages are coupled together by tension elements and transverse links so as to reduce the angle of approach of the leading axles of the undercarriages and the guiding forces thereon. Elastic elements can be incorporated in either the tension elements or transverse links or can be used in the connection between the transverse links and undercarriages.，下面是Railway car steering bogies专利的具体信息内容。
1. A railway vehicle comprising a longitudinally extending body; a pair of longitudinally spaced apart undercarriages pivotally mounted to the underside of said body at longitudinally spaced points for supporting said body, each undercarriage having at least two axles mounted thereon and a pair of wheels on each said axle; a pair of transverse links, each link being connected to a respective one of said undercarriages; a pair of levers disposed symmetrically relative to the longitudinal axis of said body adjacent each undercarriage and articulated to opposite ends of each said link, each said lever being pivotally mounted from said body; and a pair of tension rods disposed longitudinally of said body symmetrically of said longitudinal axis thereof, each tension rod being connected at the ends thereof to a pair of said levers disposed on the same side of said longitudinal axis as said tension rod.
2. A railway vehicle as set forth in claim 1 wherein each said lever is an angle lever and each said tension rod is a rod.
3. A railway vehicle as set forth in claim 1 which further comprises guiding means secured to said body for guiding said tension rod therein.
4. A railway vehicle as set forth in claim 1 which further comprises a prestressed elastic element positioned intermediately of each respective tension rod for resisting tension in said tension rod.
5. A railway vehicle as set forth in claim 1 which further comprises a pair of prestressed elastic elements positioned intermediately within each transverse link.
6. A railway vehicle comprising a longitudinally extending car body; a pair of longitudinally spaced apart undercarriages pivotally mounted on said body at longitudinally spaced points for supporting said body thereon, each undercarriage having at least one axle fixedly mounted thereon and a pair of wheels on said axle; a pair of transverse links, each link being mounted adjacent a respective one of said undercarriages for transverse movement thereto; means mounted on each undercarriage for guiding said adjacent link transversely therewith; a pair of tension rods extending symmetrically longitudinally of said car body, each tension rod being articulated at each end to a respective end of said links; and elastic elements connected between each tension rod and each link to elastically transmit forces therebetween.
7. A railway vehicle as set forth in claim 6 wherein said elastic elements are mounted within said tension rods.
8. A railway vehicle as set forth in claim 6 wherein said elastic elements are mounted within said transverse links, said elastic elements in one link having means for resisting tension and said elastic elements in the other link having means for resisting compression.
9. A railway vehicle as set forth in claim 6 which further comprises a plurality of angle levers, each angle lever being pivotally mounted on said car body and connected at one end to one end of one tension rod and at another end to one end of one link, each pair of said angle levers connected to a respective tension rod being pivotally mounted for simultaneous rotation in opposite directions relative to said car body.
10. A railway vehicle as set forth in claim 6 wherein said means includes a vertical pin centrally of each transverse link, a yoke mounted on each truck and a guide piece pivotally mounted on said yoke and guiding said vertical pin therein.
11. A railway vehicle as set forth in claim 6 wherein said means includes a pair of levers pivotally mounted in depending relation on said car body and pivotally connected to opposite ends of each transverse link, and a pair of second tension rods connected to each truck, each said second tension rod being pivotally connected to a respective one of said pair of levers.
12. A railway vehicle as set forth in claim 11 which further comprises an elastic element in each said second tension rod for elastically transmitting forces therethrough.
