Example 1
Referring to fig. 1 and 2, a planar third rail 1 is shown arranged to be mounted on a sleeper or a track plate between two rails 2 of a conventional railway line; referring to fig. 3, the electromagnetic pressure device 4 is disposed below the wheel carrier 3 of the vehicle and above the planar third rail 1, and when the electromagnetic pressure device works, a strong electromagnetic attraction force is generated on the planar third rail below the electromagnetic pressure device, so that the friction pressure of the steel wheels 5 mounted on the wheel carrier to the steel rail 2 is greatly increased, and the driving friction force of the steel wheels 5 to the steel rail 2 is greatly increased. The defect that the driving force of the vehicle is increased only by increasing the self weight of the vehicle and increasing the friction force between the wheel rails in the conventional rail transit is overcome. The dead weight of the vehicle is greatly reduced, so that the manufacturing cost of the vehicle is reduced, the manufacturing cost, the maintenance cost and the construction difficulty of a line are reduced, the energy consumption of the vehicle is greatly reduced, and the vehicle is energy-saving and environment-friendly; the vehicle operation safety is greatly increased. The device is widely applicable to various high, medium and low speed rail transit transportation.
Referring to fig. 4, in application, for compatibility with the current rail transit system, the rail surface of a plane third rail 1 arranged in a line is higher than the rail surface of a steel rail 2 in the current line, so that a pressure electromagnet installed below a wheel carrier smoothly passes through a turnout, and the universality of a vehicle and the line is improved.
In application, the electromagnetic pressure device can also be directly arranged and installed below the vehicle, so that the friction pressure between wheel rails during the running of the vehicle is increased.

Example 2
Referring to fig. 4, as shown in the figure, the driving rubber wheel 7 mounted on the vehicle wheel carrier 3 runs on the planar third rail 1, because the contact surface between the driving rubber wheel 7 and the rail surface of the planar third rail 1 is much larger than that between the current rail traffic wheel rails, the driving friction force of the vehicle running is greatly improved through the driving rubber wheel running on the rail surface of the planar third rail, and thus the energy consumption is greatly reduced. In application, according to different use environments, a composite driving wheel or a planar driving steel wheel can be used for replacing a driving rubber wheel.
