    摘要: Disclosed is a chassis for an unmanned guided carrier, wherein the chassis comprises a chassis body (100), two driving wheel set modules (200) and a torsion shaft caster module (300) mounted on the chassis body (100), the torsion shaft caster module (300) comprises a torsion shaft (310) rotatably mounted on the chassis body (100) and two supports (320), one end of each of the two supports (320) is fixed to one of both ends of the torsion shaft (310) respectively, an universal wheel (330) is mounted at the other end of each of the two supports (320), an elastic member (340) is provided between said other end of each of the two supports (320) mounted with the universal wheel (330) and the chassis body (100), the elastic member (340) applies an elastic force to the universal wheel (330) to make it cling to a ground. The embodiment of the application also discloses an unmanned guided carrier. The above solutions can solve the problem that the chassis of the current unguided carrier is easy to shake when traveling.

    摘要: The present application discloses a differential drive device applied to an AGV, relating to the field of wheeled drivers, and being able to effectively reduce the total height of the differential drive device. The differential drive device includes a differential drive unit (2), a top plate (1) and an outer cover (3). The top plate (1) is installed on a top end of the outer cover (3). The differential drive unit (2) is located in the outer cover (3) at a lower side of the top plate (1). The top plate (1) is supported on the differential drive unit (2). An inner side wall of the outer cover (3) is circular-shaped. The present application applies to apparatuses with transportation functions.
