Abstract

A vehicle steering system transmission comprising a driver connected to a driver shaft, the driver shaft connected to an output shaft by a flexible link, a first sensor sensing the driver shaft, a control unit receiving a signal from the first sensor, and the control unit transmitting a signal to the driver to control an output shaft movement.

First claim

We claim:

1. A vehicle steering system transmission comprising:
a driver connected to a driver shaft;
the driver shaft connected to an output shaft by a first flexible link;
a first sensor sensing the driver shaft angular position;
a second shaft, the second shaft connected to the driver shaft by the first flexible link and connected to the output shaft by a second flexible link;
a second sensor sensing the second shaft angular position;
a control unit receiving a signal from the first sensor and second sensor; and
the control unit transmitting a signal to the driver to control an output shaft movement.

2. The vehicle steering system transmission as in claim 1 , wherein the flexible link comprises a belt.

3. The vehicle steering system transmission as in claim 1 wherein the flexible link comprises a chain.

4. The vehicle steering system transmission as in claim 1 , wherein the control unit is in communication with a vehicle control system.

5. The vehicle steering system transmission as in claim 1 , wherein the output shaft comprises a vehicle steering shaft.

6. The vehicle steering system transmission as in claim 5 further comprising a third sensor sensing the vehicle steering shaft.

7. The vehicle steering system transmission as in claim 6 , wherein the third sensor senses a torque.

8. The vehicle steering system transmission as in claim 7 , wherein the third sensor transmits a signal to the control unit.

9. A vehicle steering system transmission comprising:
a driver connected to a driver shaft;
the driver shaft connected to an output shaft by a first linkage;
a first sensor sensing the driver shaft angular position;
a second shaft, the second shaft connected to the driver shaft by the first linkage and connected to the output shaft by a second linkage;
a second sensor sensing the second shaft angular position;
a control unit receiving a signal from the first sensor and the second sensor; and
the control unit transmitting a signal to the driver to control an output shaft movement.

10. The vehicle steering system transmission as in claim 9 , wherein the control unit is in communication with a vehicle control system.

11. The vehicle steering system transmission as in claim 9 , wherein the output shaft comprises a steering shaft.

12. The vehicle steering system transmission as in claim 11 further comprising a third sensor sensing the steering shaft.

13. The vehicle steering system transmission as in claim 12 , wherein the third sensor senses a torque.

14. The vehicle steering system transmission as in claim 13 , wherein the third sensor transmits a signal to the control unit.

15. The vehicle steering system transmission as in claim 9 , wherein the first linkage comprises a belt.
