Title:
TRANSMISSION MECHANISM
Document Type and Number:
WIPO Patent Application WO/2022/190323
Kind Code:
A1
Abstract:
[Problem] To provide a transmission mechanism that, when a gear shifting operation takes place, makes it possible to match the phase of a transmission wheel to a chain or a toothed belt by causing the transmission wheel to be in a rotation-permitted state. [Solution] A transmission mechanism (1A) comprises: a main shaft; a first and second disk set (7A, 7B), each comprising a first and second disk (10A, 11A, 10B, 11B) arranged orthogonal to and in close proximity to the main shaft; and a composite transmission wheel (S) that includes a plurality of guide rods (9) and a plurality of transmission wheels (18) that are composed of sprockets or pinions. The transmission mechanism (1A): is configured so as to allow gear shifting by changing the radius of the composite transmission wheel (S); is provided with at least one clutch mechanism (21, 22) in which each transmission wheel (18) is able to be switched between a rotation-prohibited state and a rotation-permitted state; and by means of the clutch mechanism (21, 22) causes each transmission wheel (18) to be in a rotation-permitted state when a gear shifting operation takes place, and causes each transmission wheel (18) to be in a rotation-prohibited state when a gear shifting operation is not taking place.
