Abstract
In a motor in hub driveline (fig 2) there is provided a central circular stator mounted with electro magnets (1) with both poles facing outwards in contact with an outer tire (2). The poles of the electro magnets are selectively switched to interact with permanent magnets (3) mounted in or on the surface of the tire to repel the tire locally and move a gap round the stator to produce rotary output of the tire at reduced ratio and without bearings
Claims
1. ) a combined actuator and reducer, comprising: a reference member with a contact surface;
an output member;
a compliant actuating member in continuous contact with the output member, the actuator member having a traction surface facing the contact surface of the reference member and comprising actuator zones, each actuator zone being energisable to sequentially move a corresponding portion of the traction surface of the actuating member with the contact surface of the reference member depending on the energised state of the actuator zone;
an energy source operatively coupled to the actuator zone for sequentially changing the energised state of the actuator zones and
the actuator member providing a torque transmission path between the reference member and the output member.
2. ) as in 1 where the energising means comprise electro magnets whose North or South poles form the contact surface of the reference member and are energiseably coupled to permanent magnets in the the actuator member and where the permanent magnet's appropriate poles are on or close to the traction surface of the actuator member and there is compliant material provided between the permanent magnets and the output.
3. ) as in 1 where the output and reference members are circular and the compliant actuating member is endless.
4. ) as in 1 where the reference member is linear or curved and both the actuating member and the output are linear or curved.
5. ) a combined actuator and reducer, comprising: a reference member with a contact surface;
a compliant output member with a contact surface;
an actuating member between the reference member and the output member having traction means and moveable between the reference member and the output member and being energisable to simultaneously traverse the surface of both the reference member and the output member to move the relative position of the contact line between the output member and the reference member.
6. ) a combined actuator and reducer, comprising: an output member with a contact surface;
a reference member;
an actuating member;
a compliant member between the actuating member and the reference member;
the actuating member including rigid units butted together and said units forming a traction surface of the actuating member sufficiently longer than the contact surface of the output member that two of said units cannot touch the contact surface of the output when the other units are in contact with the contact surface and said units being energisable in sequence to move a corresponding portion of the traction surface with the contact surface depending on an energised state of the actuator units;
An energy source operatively coupled to the actuator units for sequentially changing the
6
energised state of the actuator zones and:
the actuator member and the compliant member providing a torque transmission path between the reference member and the output member.
7. ) as in 6 where the units of the actuating member are flexibly joined or linked to be in a toggle relationship when in contact with the contact surface of the output include piezo elements
8. ) as in 6 where the actuating member comprises a chain and the output member comprises a sprocket
9. ) a motor as in any of the above where output speed change is effected by changing the rate of switching of the energising means and or changing the force of the input acting on the actuator second member, so as to change the length of the gap(s)between the actuator traction surface and the output surface and thereby change the reduction ratio and so change the output speed.
10. ) a motor as in any of the above where a second motor is movably mounted within and to a first motor, preferably with gimbals so that the angle of rotary output of the second motor may be adjusted by rotating the first motor
11. ) a motor as in any of the above where inputs for the time being not actively driving movement are switched on in reverse mode to increase friction between the first and second members
12. ) as in any of the above where the reference member and the output are releasably tethered to prevent movement so that by releasing the reference member and tethering the output member the reference member becomes the output
