Patent Searching and Data


Title:
TORQUE DETECTION SENSOR AND POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/149204
Kind Code:
A1
Abstract:
This torque detection sensor comprises a first resistance wire pattern and a second resistance wire pattern. The first resistance wire pattern is an arc-shape or ring-shape pattern in which resistance wires, inclined to one side in the circumferential direction from the radial direction of a circular body, are arranged in the circumferential direction. The second resistance wire pattern is an arc-shape or ring-shape pattern in which resistance wires, inclined to the other side in the circumferential direction from the radial direction of a circular body, are arranged in the circumferential direction. The first resistance wire and the second resistance wire are arranged in non-overlapping positions. For that reason, it is possible to configure these resistance wires in a single layer. Consequently, it is possible to achieve a low-cost and thin torque detection sensor for a round body.
