Vehicle body and maglev vehicle

Abstract

The embodiment of the invention provides a vehicle body and a maglev vehicle. The vehicle body is made of composite materials and comprises a bottom frame, a pair of side walls, a vehicle roof and a grounding network system. The chassis is located at the bottom of the vehicle body and comprises a bottom plate. The pair of side walls is connected to the two sides of the underframe in the transverse direction, and the bottoms of the side walls are connected with the underframe. The top of the pair of side walls is covered with the car roof, and the two sides of the car roof in the transverse direction are correspondingly connected with the pair of side walls respectively. The grounding network system is electrically connected with each preset grounding point on the vehicle body through a grounding strip and comprises a bottom plate lower grounding network connected to the bottom surface of the chassis, a vehicle roof grounding network connected to the bottom surface of the vehicle roof and a side wall grounding network connected to the inner wall of the side wall; the bottom plate lower grounding network longitudinally extends to penetrate through the vehicle body, the roof grounding network longitudinally extends to penetrate through the roof, the side wall grounding network vertically extends, the upper end of the side wall grounding network is electrically connected with the roof grounding network, and the lower end of the side wall grounding network is electrically connected with the bottom plate lower grounding network, so that the grounding requirement of the composite vehicle body is met.

Description

technical field [0001] The present application relates to magnetic levitation vehicle technology, in particular, to a vehicle body and a magnetic levitation vehicle. Background technique [0002] The magnetic levitation vehicle uses electromagnetic force to suspend the supported object and the stator. The weight of the vehicle body structure itself is an important factor affecting the passenger capacity and driving speed of the magnetic levitation vehicle. Conventional maglev vehicles include structures such as roof, chassis, side walls, driver's cab, and end walls. The entire vehicle is made of aluminum alloy, and most of the parts are connected by welding. The car body adopting aluminum alloy profiles has the following disadvantages: the weight of the car body is large, the amount of welding is large, the welding deformation is large, and the appearance profile is poor. For the metal car body, it is a good conductor and can provide grounding requirements. However, for non...

Problems solved by technology

The car body using aluminum alloy profiles has the following disadvantages: the weight of the car body is large, the welding volume is large, the welding deformation is large, and the appearance contour is poor

For the metal car body, it is a good conductor and can provide grounding requirements. However, for non-metallic car bodies, since the resistance of non-metallic materials is about a thousand times that of traditional metal resistance, it cannot meet the grounding requirements.
