Disclosed are a railway guiding device and a road-rail vehicle. The railway guiding device comprises an upper rotary seat (1), a lower rotary seat (2) and guide wheels (3) capable of being lifted. Bearings (4) are arranged between the upper rotary seat (1) and the lower rotary seat (2). The bottom of the upper rotary seat (1) is provided with a reset plate (11) extending downwardly. The lower rotary seat (2) is provided with a plurality of rubber blocks (21), the plurality of rubber blocks (21) are symmetrically distributed at two sides of the reset plate (11), and the reset plate (11) is clamped between the rubber blocks (21). The guide wheels (3) are mounted on the lower rotary seat (2). Therefore, the improvement in the curve negotiation capability and universality of the railway guiding device is realized.

Disclosed is a road-rail vehicle driven by rubber wheels. The road-rail vehicle comprises a vehicle frame (100). Rotatable rubber wheel sets are respectively arranged at a front end and a rear end of the vehicle frame (100). Each rubber wheel set comprises two wheels (101). Each of the rubber wheel sets is equipped with a railway guiding device (200), and the railway guiding device (200) comprises an upper rotary seat (1), a lower rotary seat (2) and guide wheels (3) capable of being lifted. Bearings (4) are arranged between the upper rotary seat (1) and the lower rotary seat (2). The bottom of the upper rotary seat (1) is provided with a reset plate (11) extending downwardly. The lower rotary seat (2) is provided with a plurality of rubber blocks (21), the plurality of rubber blocks (21) are symmetrically distributed at two sides of the reset plate (11), and the reset plate (11) is clamped between the rubber blocks (21). The guide wheels (3) are mounted on the lower rotary seat (2). The upper rotary seat (1) is fixed at the bottom of the vehicle frame (100). The railway guiding device (200) is located between two wheels (101) of the corresponding rubber wheel set. The improvement in the curve negotiation capability and universality of the road-rail vehicle driven by the rubber wheels is realized.
Disclosed are a carriage hinge device and a tramcar. The carriage hinge device comprises a bearing frame (1), a lower hinge assembly (2) and an upper hinge assembly (3), wherein the lower hinge assembly (2) comprises a first joint bearing (21), a second joint bearing (22), a first connection board (23) and a second connection board (24). The connection boards are hinged on the bearing frame via the joint bearings. An upper mounting shaft is provided on an upper part of the bearing frame (1), and a rubber bearing (11) is provided on the upper mounting shaft. The upper hinge assembly (3) comprises two first connection rods (31), a second connection rod (32), two first mounting bases (33) and two second mounting bases (34), wherein one end of the first connection rod (31) is hinged to the bearing frame (1) via the rubber bearing (11), and the other end of the first connection rod (31) is hinged to the first mounting base (33) via a third joint bearing (311); and two ends of the second connection rod (32) are hinged between the two second mounting bases (34) via fourth joint bearings (321), with one of the second mounting bases (34) being fixed on the upper part of the bearing frame (1). The carriage hinge device improves the reliability of the tramcar.
