Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to an EPS steering torque sensor that is easy to install. Background Technology

[0002] EPS (Electric Power Steering) systems represent a future trend in power steering systems. They utilize sensors to detect the magnitude and direction of torque or steering angle generated by the steering wheel during driver input, converting this information into digital signals that are input to the control unit. The control unit then processes these signals to obtain a torque adapted to the driving conditions, and sends a command to drive the electric motor. The motor's output torque assists the steering wheel through a transmission system. Therefore, the torque sensor is one of the crucial components in an EPS system. There are many types of torque sensors, primarily including potentiometer-type torque sensors, metal resistance strain gauge torque sensors, and non-contact torque sensors. With technological advancements, sensors with higher accuracy and lower cost will emerge.

[0003] Existing application CN201620949543.2 discloses a torque sensor, including an elastic shaft, a strain gauge connected to the elastic shaft, and a plug for outputting signals. The torque sensor also includes a slip ring, a spring, and a carbon brush holder. The slip ring is electrically connected to the strain gauge; one end of the spring is electrically connected to the slip ring, and the other end is electrically connected to the plug; the carbon brush holder is used to fix the position of the spring. Compared to traditional sensors that directly connect the strain gauge to the plug, this technical solution, by setting up a spring, slip ring, and carbon brush holder, makes the sensor measurement more accurate. Furthermore, the presence of the carbon brush holder makes the sensor structure more stable. However, existing torque sensors do not consider the need for internal heat dissipation during machine operation. Also, automotive torque lever detection involves two rotation speeds: low speed and high speed. Different probes are required for different rotation speeds; otherwise, the measurement results will be affected and prone to errors. Utility Model Content
