Abstract
An isolated torque sensing device is described having a torque tube that may be configured in an axle of a bicycle or e-bike. A strain gauge is configured on either the inner or outer diameter of the torque tube. The torque sensor system may be configured in a 4-point bending configuration, wherein force from bearings within the axle, apply force to the torque tube.
Claims20
A torque sensing system, comprising:
- a torque tube disposed around an axle;
- and
- a strain gauge disposed on the torque tube,
- wherein the torque tube experiences a strain responsive to an pedaling force, and wherein at least a portion of the pedaling force is transferred to the torque tube via at least one support bearing.
The torque sensing system of claim 17, wherein the bicycle is an e-bike having an electric motor.
The torque sensing system of claim 18, wherein the strain gauge is connected with said electric motor, and whereby a signal from said strain gauge changes an output from the electric motor.
