Description

Technical Field

[0001] This utility model relates to the field of automated transportation device technology, and in particular to a vehicle chassis traveling device. Background Technology

[0002] Traditional car chassis walking devices have universal wheels installed at the four corners and a differential drive wheel installed in the middle. All six wheels are flush with the ground contact surface, and the movement of the car chassis is driven by the rotation of the drive wheel.

[0003] However, when the chassis of the car travels on uneven or sloping ground, the drive wheels will be suspended in the air because the front and rear casters are in contact with the ground. This results in insufficient or no driving force for the chassis, making it unable to move. Utility Model Content
