Abstract

A wheel for a vehicle is provided. The wheel has a rim configured for mounting a tire thereto. The wheel also has a rotary drive member that is integrally connected to the rim. The drive member is configured to be operatively connected to a motor of the vehicle.

First claim

What is claimed is:

1. A wheel for a vehicle, comprising:
a rim configured for mounting a tire, the rim comprising a sleeve;
a hub:
a plurality of spokes connecting the hub to the sleeve; and
a rotary drive member integrally connected to the rim and configured to be operatively connected to a motor of the vehicle.

2. The wheel of claim 1 , wherein the rotary drive member is axially offset from the rim.

3. The wheel of claim 1 , wherein:
the rotary drive member has an outer diameter that is greater than an inner diameter of the sleeve.

4. The wheel of claim 3 , wherein the outer diameter of the rotary drive member is greater than the inner diameter of the sleeve measured at a lateral edge of the sleeve, the lateral edge of the sleeve being axially between an axial center of the wheel and the rotary drive member.

5. The wheel of claim 1 , wherein:
the rotary drive member has an outer diameter;
the wheel has a maximum diameter defined by the rim; and
a ratio of the outer diameter of the rotary drive member over the maximum diameter of the wheel is at least 0.7.

6. The wheel of claim 5 , wherein the ratio of the outer diameter of the rotary drive member over the maximum diameter of the wheel is at least 0.9.

7. The wheel of claim 1 , wherein the rotary drive member is a pulley.

8. The wheel of claim 1 , further comprising a plurality of branches integrally connecting the rotary drive member to the rim, the plurality of branches being circumferentially spaced apart from one another.

9. The wheel of claim 1 , wherein the rim and the rotary drive member are concentric.

10. The wheel of claim 1 , wherein:
the rotary drive member is integrally connected to the sleeve.

11. A wheel assembly comprising:
the wheel of claim 1 ; and
a tire mounted to the rim of the wheel.

12. A vehicle comprising:
a frame;
a suspension assembly operatively connected to the frame;
a motor supported by the frame; and
the wheel assembly of claim 11 rotatably connected to the suspension assembly, the rotary drive member being operatively connected to the motor.

13. The vehicle of claim 12 , wherein:
the suspension assembly comprises:
a swing arm having a proximal end and a distal end,
the proximal end of the swing arm being pivotally connected to the frame about a swing arm pivot axis; and
a shock absorber connected between the swing arm and the frame; and

the wheel is rotatably connected to the distal end of the swing arm.

14. The vehicle of claim 13 , wherein the motor is mounted to the swing arm and is pivotable about the swing arm pivot axis.

15. The vehicle of claim 13 , wherein the swing arm extends at least in part inside the rotary drive member.

16. The vehicle of claim 12 , wherein the motor is an electric motor.

17. The vehicle of claim 12 , wherein:
the motor comprises an output shaft; and
the vehicle comprises a transmission assembly operatively connecting the output shaft to the rotary drive member of the wheel, the transmission assembly comprising:
a driving member connected to the output shaft of the motor; and
a flexible drive element interconnecting the driving member of the motor to the rotary drive member of the wheel.

18. The vehicle of claim 17 , wherein:
the rotary drive member of the wheel has an outer diameter;
the driving member of the transmission assembly has an outer diameter; and
a ratio of the outer diameter of the rotary drive member of the wheel over the outer diameter of the driving member of the transmission assembly is at least 8.

19. The vehicle of claim 12 , wherein the suspension assembly is a rear suspension assembly.

20. A wheel for a vehicle, comprising:
a rim configured for mounting a tire, the rim comprising a sleeve; and
a rotary drive member integrally connected to the rim and configured to be operatively connected to a motor of the vehicle, the rotary drive member having an outer diameter that is greater than an inner diameter of the sleeve.

21. A wheel for a vehicle, comprising:
a rim configured for mounting a tire;
a rotary drive member integrally connected to the rim and configured to be operatively connected to a motor of the vehicle; and
a plurality of branches integrally connecting the rotary drive member to the rim, the plurality of branches being circumferentially spaced apart from one another.
