Kind Code:
A1
Abstract:
Disclosed are a trolley bus traveling system (13), and a trolley bus. The traveling system (13) is used for being connected to a bus body connecting frame (12) arranged between two carriages (11) in the bus. The traveling system (13) comprises two traveling assemblies, which are symmetrically arranged on two sides of the bus body connecting frame (12) in a transverse direction, which transverse direction is perpendicular to the advancing direction of the bus. The traveling assemblies comprise axle boxes (2); upper fork arms (51) connected between the top of the axle boxes (2) and the bus body connecting frame (12); lower fork arms (52) connected between the bottom of the axle boxes (2) and the bus body connecting frame (12); and wheels (4) rotationally connected to the axle boxes (2). The trolley bus traveling system (13) can reduce the floor height of the carriages (11), which facilitates the lowering of the center of gravity of the carriages (11).
