Problems solved by technology

[0003] The driver's cab and the car body of the existing rail vehicle are fixed by welding. During the running of the rail vehicle, tearing force is easily generated between the driver's cab and the car body, which in turn leads to damage to the driver's cab and the car body. The reliability is low. Difference

Embodiment Construction

[0017] Please refer to figure 1 , the present invention provides a rail vehicle, including a driver's cab 101 and a car body 102, and the driver's cab 101 and the car body 102 are connected by first bolts 116 .

[0018] In this embodiment, since the driver's cab 101 and the car body 102 are separate parts and connected by the first bolt 116, the mechanical performance of the driver's cab 101 and the car body 102 is improved, and the driver's cab 101 is reduced during the running of the rail vehicle. The tearing force generated between the cabin 101 and the vehicle body 102 avoids damage to the cab 101 and the vehicle body 102, and improves the reliability of the rail vehicle. In addition, since the cab 101 is a separate component, modular production of the cab 101 can be realized.

[0019] In this embodiment, preferably, the rear portion of the driver's cab 101 is provided with an end wall 103, and the end wall 103 is provided with a first installation beam 104; the end of th...

Abstract

The invention provides a rail vehicle which comprises a cab and a vehicle body. The cab and the vehicle body are connected through first bolts. The reliability of the rail vehicle can be improved.

Description

technical field [0001] The invention relates to rail equipment technology, in particular to a rail vehicle. Background technique [0002] The driver's cab of a rail vehicle is a very important part of the vehicle. Drivers and passengers need to perform various operations in the cab to ensure the safe operation of the rail vehicle. [0003] The driver's cab and the car body of the existing rail vehicle are fixed by welding. During the running of the rail vehicle, tearing force is easily generated between the driver's cab and the car body, which in turn leads to damage to the driver's cab and the car body. The reliability is low. Difference. Contents of the invention [0004] The invention provides a rail vehicle to improve the reliability of the rail vehicle. [0005] The invention provides a rail vehicle, which includes a driver's cab and a car body, and the driver's cab and the car body are connected by first bolts. [0006] Based on the above, the rail vehicle provide...
