HUB MOTOR (VERSIONS) Russian patent published in 2004 - IPC

FIELD: mechanical engineering; transport engineering; bicycles.

SUBSTANCE: two-side wheel rotating motor of fork attachment arranged in hub motor has two alternating sheaves located at different sides of wheel, namely, working sheave and idle sheave. In working sheave, single-nose cam acts by its working lowering surface onto wheel ring to run the ring. Simultaneously, single-nose lifting cam acts by its working lifting surface onto round intermediately rotating disk, thus providing constant position of disk axle together with attachment portal and wheel fork or platform together with portal. Working sheave is coupled is coupled with idle sheave through wheel synchronizer. At the end of working stroke, load is re-distributed to idle sheave through portal. Alternation of sheaves provides rotation of hub motor under action of load. Use of single-noise lifting and rotating cams makes it possible to form simple design with larger sizes of single-nose lifting cams at low rotation torque. To decrease sizes of single-nose lifting cam, use is made of cam pulley block which provides increasing of size of single-nose rotating cam and rotation torque without practically changing overall dimensions. Multinose rotating cam, speed increasing mechanism and pulley block make it possible to form compact design and to increase rotation torque. One-side wheel rotation mechanism in stationary hub motor of cantilever attachment-type located from outer free side and provided with multinose rotating cam, speed increasing mechanism and cam pulley block make it possible to form design with maximum rotation torque. Use in axial attachment-type hub wheel of railway pair of single shifted wheel rotation mechanism arranged from inner axial side and provided with multinose rotating cam, wheel speed increasing mechanism and cam pulley block makes it possible to get compact design with lower rotation torque.

EFFECT: provision of hub motor rotating under action of load use in different vehicles or hub motor energy for other mechanisms.
