Abstract
Description
Technical Field

[0002] Utility model CN 220298597 U discloses a steering wheel angle detection device for small and medium-sized trucks, relating to the field of steering wheel angle detection technology. It includes: a steering wheel fixed-end main shaft; a detection mechanism is fixedly mounted on the outer wall of the steering wheel fixed-end main shaft; the detection mechanism includes a positioning mounting bracket; an adjusting bracket is fixedly mounted on one side of the outer wall of the positioning mounting bracket; an encoder mounting bracket is fixedly mounted at the bottom of the adjusting bracket; an encoder is fixedly mounted on the inner wall of the encoder mounting bracket; a driven gear is fixedly sleeved on the output end of the encoder; and a driving gear is meshed with the outer wall of the driven gear. Because this device is fixedly installed using bolts, it can monitor the steering wheel and tire steering angles in real time without any modifications to the original vehicle.
[0003] In the above scheme, the encoder is unstable during the angle acquisition process and the encoder position is unstable during the rotation of the steering wheel. Therefore, during the steering wheel turning, inertial force, external impact or mechanical loosening may cause relative displacement (side slip) between the encoder and the steering shaft, resulting in angle measurement errors or even equipment damage.
