Multipart chain wheel for transmitting torque of gear box to motorcycle, has ring including toothed ring-rudiments, where pass-screw, hole, counterbore and apertures axially and radially are interconnected with inner and toothed ring

摘要

The wheel (1) has peripheral gears positively cooperated with traction mechanism, and an inner ring (2) comprising through-holes for fastening a multipart chain wheel at a wheel hub. The inner ring includes inner ring-rudiments (2A) for retaining a toothed ring (8). The toothed ring includes toothed ring-rudiments (11) that are set in radial inward and spatially associated with inner ring-rudiments of the inner ring. A pass-screw (12), bore hole (13), counterbore and apertures are axially and radially interconnected with the inner ring and the toothed ring.
