Abstract

The self adaptable torque and rotating speed drive sensor for transmissions comprise an output shaft on the transmission case, with a barrel cased outside the outside shaft on the transmission case, the driven gear matching with the shaft barrel which connects with the output shaft through elastic self alignment coupler, which is made of the No.1 half coupler matching with the right end of the shaft barrel, the No.2 half coupler matching with the right of the output shaft, the rolling block between the No.1 and No.2 half couplers, the No.1 and No.2 spring base and the spring components between them. On the transmission case, there is a displacement device and a speed sensing component. Compact in structure, this invention synchronically inspects the torque and speed signal while directly participating in the drive, with accurate signals acquired. It provides the most reliable basis for the controller of following vehicles or machines to make right judgment other than the self adaptation feature.

Description

technical field [0001] The invention relates to an additional device of a speed reducer, in particular to a transmission adaptive torque and rotational speed transmission sensor device of a vehicle or machine equipment. Background technique [0002] Changes in torque and speed are important information on the operating conditions of vehicles and machinery. Therefore, the detection of torque and speed is an important part of vehicle and machinery product development, quality inspection, optimal control, working condition monitoring and fault diagnosis. There are many mature technologies available for speed detection. Although torque sensors with different characteristics have been developed for specific occasions, they also have their own shortcomings. Common torque sensors include strain-type torque sensors, magnetoelastic torque sensors, angle-type torque sensors and other types of torque sensors. None of these torque sensors can directly participate in the transmission, t...
