Description

Technical Field

[0001] The present invention relates to the field of transportation technology, and in particular to a high-speed rail vehicle for both road and rail and a rail system thereof. Background Art

[0002] In the traditional rail transit system, the main factor limiting the further improvement of the speed of rail vehicles is the friction between the wheels and the tracks. If the friction is too small, the rail vehicles will not have the power to move forward. For example, on a smooth track, the wheels of the rail vehicles will slip. If the friction is large enough, the power must be large enough to achieve ultra-high speed, but this is too energy-consuming and uneconomical. My Chinese patent CN 113089386 A discloses a fixed turnout track and a vehicle-mounted track change system, which represents the development trend of a new type of rail transit personal rapid transportation system (Personal RaidTransit, referred to as PRT) in the future, but it still needs to increase the speed of rail vehicles so that they can travel at ultra-high speed in inter-city or inter-provincial network transportation. In addition, in places where it is difficult to lay tracks, such as elevator rooms, corridors, etc., its rail vehicles cannot reach them, and cannot really reach anywhere. Summary of the invention

[0003] In order to improve some of the deficiencies in the above-mentioned prior art, the first purpose of the present invention is to provide a high-speed rail vehicle, which has a high speed, is energy-saving, and is conducive to forming a rail transportation network between cities or provinces.

[0004] In order to improve some of the deficiencies in the above-mentioned prior art, the second purpose of the present invention is to provide a multifunctional high-speed rail vehicle that can travel on rails or on roads, so that the rail vehicle can reach any place.

[0005] In order to improve some of the deficiencies in the above-mentioned prior art, the third object of the present invention is to provide a rail system, which can realize the free switching of rail vehicles between rail driving and road driving at the end of the rail.

The frame is mounted on the axle. The anti-derail device is movably arranged just below the frame and close to the wheel group, and when the high-speed rail vehicle travels on track, the anti-derail device is suitable for cooperating with the inner surface of the track. In this scheme, similar to the concept of maglev trains, minimizing the friction between the track and the rail vehicle can increase the speed. Therefore, the friction between the load-bearing wheel and the track can be reduced by reducing the contact area between the load-bearing wheel and the track and / or increasing the smoothness of the contact surface between the load-bearing wheel and the track. The smoothness of the contact surface between the load-bearing wheel and the track can be improved by selecting materials, such as a smooth steel track surface and a smooth steel load-bearing wheel surface, or releasing lubricating fluid on the surface of the load-bearing wheel, etc. At the same time, the power wheel cooperates with the rack rail on the track described in the third purpose of the present invention to provide a strong driving force for the rail vehicle to move forward. Since the power wheel is not in close contact with the rack rail on the track described in the third purpose of the present invention and does not bear the weight of the vehicle, the friction is small during the forward process, thereby realizing high-speed travel of the rail vehicle. Due to the small friction, energy can be saved, which is conducive to the formation of a rail transportation network between cities.

[0078] In order to improve some of the deficiencies in the above-mentioned prior art, the second purpose of the present invention is to provide a multifunctional high-speed rail vehicle that can travel on rails or on roads, so that the rail vehicle can reach any place.

[0079] In order to improve some of the deficiencies in the above-mentioned prior art, the third object of the present invention is to provide a rail system, which can realize the free switching of rail vehicles between rail driving and road driving at the end of the rail.

[0080] A high-speed rail vehicle according to an embodiment of the first object of the present invention will be described below with reference to the accompanying drawings.

[0081] Example 1

Figure 1-3 As shown, the bogie 21 includes a wheel set assembly, a frame 211 and an anti-derailment device 31. Figure 3 , Figure 6 and Fig.10 As shown, the wheel set assembly includes an axle 203 and two wheel groups 20, the wheel group 20 includes a load-bearing wheel 201 and a power wheel 202, the load-bearing wheel 201 and the power wheel 202 are coaxial, the two wheel groups 20 are respectively installed at both ends of the axle 203, and the forward direction of the wheel group 20 is always perpendicular to the axle 203. The frame 211 is installed on the axle 203. Figure 1Shown, described anti-derail device 31 is arranged at described framework 211 bottom and near described wheel group 20, and when described high-speed rail vehicle travels on track 1, described anti-derail device 31 is suitable for cooperating with track 1 inner surface. In this scheme, similar to the concept of maglev trains, minimizing the friction between the track 1 and the rail vehicle can increase the speed. Therefore, the friction between the load-bearing wheel 201 and the track 1 can be reduced by reducing the contact area between the load-bearing wheel 201 and the track 1 and or increasing the smoothness of the contact surface between the load-bearing wheel 201 and the track 1. The smoothness of the contact surface between the load-bearing wheel 201 and the track 1 can be improved by selecting materials, such as a smooth steel track surface and a smooth steel load-bearing wheel surface, or releasing lubricating fluid on the surface of the load-bearing wheel 201. At the same time, the power wheel 202 cooperates with the rack rail 12 on the track 1 described in the third purpose of the present invention to provide a strong driving force for the rail vehicle to move forward. Since the power wheel 202 is not in close contact with the rack rail 12 on the track 1 described in the third purpose of the present invention and does not bear the weight of the vehicle, the friction is small during the forward process, thereby realizing high-speed travel of the rail vehicle.
