Abstract
A power train for heavy duty equipment comprising a flexible power cable and a sensing mechanism for monitoring the contraction of the cable as torque is applied to the cable and a member for decreasing the power to another control mechanism in response to the torque applied to the cable.
Claims9
A flexible drive mechanism operable for powering a device by transmitting torque around a bend comprising:
- an input member for ataching a first source of power;
- a housing for rotatably supporting a flexible cable;
- a flexible cable mounted in said housing, said flexible cable operable for flexing at least once per revolution and transmitting a torque during the flexing;
- said cable comprised of strands which simultaneously flex and tighten around one another during the transmission of torque to thereby produce a displacement of said cable in said housing in response to the torque applied thereto.
