  • Patent number: 11827251
    Abstract: A bogie of a rail vehicle includes a frame, which includes two box-shaped longitudinal beam main bodies and a transverse beam main body; a wheelset, which includes an axle box, an axle and wheels mounted at two ends of the axle; a drive system, which at least includes a gearbox and a drive motor. Practice has proved that the two axle boxes arranged on the inner sides of the two longitudinal beam main bodies can reduce a volume by about 10%, and reduce a weight by about 10% to 15%, which can further reduce air resistance, and realize energy saving and emission reduction. The longitudinal beam main body is located on an inner side of a wheel, a span of the two the longitudinal beam main bodies is reduced, and the torsional rigidity of the frame is reduced, which is beneficial to improving a curve passing capacity.

  • Publication number: 20230167211
    Abstract: A monomer capable forming a polymer through ring-opening metathesis polymerization and capable of depolymerization thereafter through ring-closing metathesis, wherein the monomer comprises a cycloalkene having a fused ring attached thereto to form a cycloalkene-fused ring monomer, wherein the fused ring decreases the ring strain energy of the cycloalkene to a lower ring strain energy state of 5.3 kcal/mol or lower as compared to the same cycloalkene without the fused ring having a ring strain energy above 5.3 kcal/mol and wherein the cycloalkene-fused ring monomer is capable of isomerization into a higher ring strain energy state before polymerization and method of synthesizing the monomer. The monomer is further capable of forming chemically recyclable to monomers block copolymers.
