Abstract
A rotary connector, comprises an annular rotary body inserted outside a steering shaft and integrally rotated with a steering wheel, a rotator of a steering angle sensor inserted outside the steering shaft; and a tubular joint inserted outside the steering shaft and connecting the rotary body to the rotator; wherein the rotary body and the joint are connected together by a first universal joint, and the joint and the rotator are connected together by a second universal joint.
Claims7
A rotary connector, comprising:
- an annular rotary body having a first rotational axis and disposed outside a steering shaft and integrally rotated with a steering wheel;
- a rotator of a steering angle sensor having a second rotational axis and disposed outside the steering shaft, wherein the steering angle sensor is configured to measure a steering angle of the shaft;
- and
- a tubular joint having a third rotational axis disposed outside the steering shaft and connecting the rotary body to the rotator;
- wherein the rotary body and the tubular joint are connected together by a first universal joint configured to provide relative angular displacement of the first rotational axis of the rotary body with respect to the third rotational axis of the tubular joint, and the tubular joint and the rotator are connected together by a second universal joint configured to provide relative angular displacement of the second rotational axis of the rotator with respect to the third rotational axis of the tubular joint such that rotational error between the rotary body and the rotator is reduced.
