In the embodiment of the present application, the first driving assembly 21 is configured to provide power for the first running wheels 31, the second driving assembly 22 is configured to provide power for the second running wheels 32, and the first running wheels 31 and the second running wheels 32 are configured to drive the corresponding vehicle body to run on the track 80. After the two driving assemblies (comprising the first driving assembly 21 and the second driving assembly 22) respectively and independently drive the two running wheels (comprising the first running wheel 31 and the second running wheel 32), the rotating speeds of the two running wheels can be kept consistent when the vehicle runs in a straight line, so that the vehicle runs more stably and reliably; when the vehicle turns, the rotating speeds of the two traveling wheels are controlled to change, so that the rotating speeds of the two traveling wheels are different, the rotating speed of the traveling wheel close to the outer side of the bend is larger than that of the traveling wheel close to the inner side of the bend, the dragging condition is avoided, eccentric wear of the two traveling wheels is reduced, and the service lives of the two traveling wheels are prolonged. Specifically, the first driving assembly 21 can control the first running wheels 31, the second driving assembly 22 can control the second running wheels 32, the first driving assembly 21 and the second driving assembly 22 can drive the two running wheels synchronously during straight running, and the first driving assembly 21 and the second driving assembly 22 can correspondingly adjust the rotating speeds of the two running wheels during curve running. The embodiment of the application has the beneficial effects of reducing eccentric wear of the two walking wheels and prolonging the service life of the two walking wheels.
The vehicle can be a light rail vehicle and a rail engineering vehicle, and can also be other rail vehicles.
