Title:
HOLLOW WHEEL APPARATUS AND MEANS OF TRANSPORTATION
Document Type and Number:
WIPO Patent Application WO/2019/090930
Kind Code:
A1
Abstract:
A hollow wheel apparatus (10), comprising a wheel (100) and a friction transmission mechanism (200). The wheel (100) is a hollow structure, provided with an inner surface (110). The friction transmission mechanism (200) comprises a first roller wheel (210) and an auxiliary assembly, the first roller wheel (210) being connected to a drive mechanism, the drive mechanism driving the first roller wheel (210) to rotate so as to drive the wheel (100) to rotate with respect to the ground, the auxiliary assembly being connected to the first roller wheel (210) and causing the first roller wheel (210) to abut against the inner surface (110), the auxiliary assembly also causing the maximum static friction between the first roller wheel (210) and the inner surface (110) to be greater than the maximum static friction between the first roller wheel (210) and the ground.
