Abstract
The present invention relates to a motorized hub assembly for a bicycle wheel. The assembly has a hub shaft extending along a longitudinal axis with a cavity to receive a quick release axle. A bearing having a radially inner ring is arranged radially outside the hub shaft. A hub body is rotatably mounted on the hub shaft about the longitudinal axis and an electric motor is arranged inside the hub body. A routing opening for passage of electrical conductors for the electric motor pass through a routing opening arranged radially between the inner ring of the bearing and the hub shaft.
Claims15
A motorized hub assembly for a bicycle wheel comprising:
- a hub shaft extending along a longitudinal axis and comprising a longitudinal through cavity configured to receive a quick release axle;
- at least one first bearing having a radially inner ring and arranged radially outside the hub shaft;
- a hub body radially external to the hub shaft and mounted rotatably, about a rotation axis, on the hub shaft through said first bearing;
- an electric motor arranged inside the hub body;
- a routing opening configured for the passage of electrical conductor elements connected to said electric motor, said routing opening being arranged radially between the inner ring of the first bearing and the hub shaft;
- and
- a support body provided at least at the routing opening and radially interposed between the inner ring of the first bearing and the routing opening;
- said support body configured to withstand a thrust directed in a radially inner direction exerted by the first bearing and said inner ring of the first bearing resting on said support body,
- wherein said support body has a delimiting wall for said routing opening;
- said routing opening being radially defined between said delimiting wall and said hub shaft.
A motorized hub assembly for a bicycle wheel comprising:
- a hub shaft extending along a longitudinal axis and comprising a longitudinal through cavity;
- at least one first bearing having a radially inner ring and arranged radially outside the hub shaft;
- a hub body radially external to the hub shaft and mounted rotatably, about a rotation axis, on the hub shaft through said first bearing;
- an electric motor arranged inside the hub body;
- a routing opening configured for the passage of electrical conductor elements connected to said electric motor, said routing opening being arranged radially between the inner ring of the first bearing and the hub shaft;
- and
- a support body provided at least at the routing opening and radially interposed between the inner ring of the first bearing and the routing opening;
- said support body configured to withstand a thrust directed in a radially inner direction exerted by the first bearing and said inner ring of the first bearing resting on said support body,
- wherein said support body comprises a radial passage axially outside of said first bearing and defining a radial outlet for said routing opening and passage of said electrical conductor elements.
