REE Automotive has been granted a patent for an apparatus that measures the steering angle of a wheel assembly. The apparatus includes a reference bracket, a rotating bracket, and an angle sensor. The brackets are rotatably coupled and the mounting ends are connected to the suspended wheel mount and suspension arm. The reference bracket is positioned on a plane defined by the steering axis and rotation axis, ensuring alignment during vertical motion of the wheel mount.

Apparatus for measuring steering angle of a wheel assembly
A recently granted patent (Publication Number: US11713076B2) describes an apparatus for measuring the steering angle of a wheel assembly. The apparatus includes a reference bracket, a rotating bracket, and an angle sensor. The reference bracket and rotating bracket are rotatably coupled at a rotation coupling point, allowing them to rotate with respect to each other. The mounting end of the rotating bracket is coupled with the suspended wheel mount, while the mounting end of the reference bracket is coupled with the suspension arm.
During vertical motion of the suspended wheel mount, the mounting end of the reference bracket remains positioned on a plane defined by the steering axis of the suspended wheel mount and the rotation axis between the suspension arm and the wheel mount. This ensures that the rotation axis of the angle sensor stays aligned with the steering axis during vertical motion.
The patent claims also specify that the measurement end of the reference bracket extends perpendicularly from a longitudinal section of the reference bracket. Additionally, the longitudinal section of the reference bracket is perpendicular to the steering axis. The apparatus can be coupled with either the upper or lower end of the suspended wheel mount.
The angle sensor is coupled with either the rotating bracket or the reference bracket at the rotation coupling point. The patent claims also describe variations in the positioning of the mounting end of the reference bracket and the plane defined by the steering axis and rotation axis.
Overall, this patented apparatus provides a solution for accurately measuring the steering angle of a wheel assembly, particularly during vertical motion. By ensuring the alignment of the rotation axis of the angle sensor with the steering axis, this apparatus can contribute to improved steering angle measurement and analysis in various applications.
