Problems solved by technology

There are many mature technologies available for speed detection. Although torque sensors with their own characteristics have been developed for specific occasions, they also have their own shortcomings. Common torque sensors include strain-type torque sensors. Sensors, magnetoelastic torque sensors, angle torque sensors and other types of torque sensors. These torque sensors cannot directly participate in the transmission, so the accuracy and reliability of the detection results are poor. The integration of the sensor and the transmission components, in In the process of directly participating in the transmission, the synchronous and automatic transmission of torque and speed change information is the development trend of torque and speed sensing technology

Embodiment 1

[0030] Example 1: The displacement transmission mechanism adopts a differential transformer type displacement sensor. See Figure 1, Figure 2, Figure 3, Figure 4, Figure 5, Figure 6, Figure 7, Figure 8, Figure 9, Figure 10, Figure 11, Figure 12 and Figure 13, the drive shaft cylinder 4 is installed on the box 1 connected to the frame, and matched with the first bearing 2 and the second bearing 3 at both ends of the box; the flower keyboard 22 is fixedly connected to the first drive shaft 5. And make the flower keyboard 22 fit with the spline groove in the transmission shaft cylinder 4, and the other end of the first transmission shaft 5 is connected with the input shaft 9 through a universal joint;

[0031] First install the second drive shaft 8 with the third bearing 6 and spring assembly 17 (consisting of 6 disc springs) at the left end into the left end of the drive shaft cylinder 4, and make the third bearing 6 and the inner wall of the drive shaft cylinder 4 Fit; then install ...

Embodiment 2

[0034] Embodiment 2: The displacement transmission mechanism adopts a photoelectric-electric eddy current displacement sensor. Referring to FIG. 14, since the type of displacement sensor used is different from that of Embodiment 1, the structure of the displacement transmission component is different from that of Embodiment 1. This can be done by those skilled in the art without creative work. . The rest is the same as in Example 1.

Embodiment 3

[0035] Embodiment 3: The displacement transmission mechanism adopts a Hall displacement sensor. Referring to FIG. 15, since the type of displacement sensor used is different from that of Embodiment 1 and Embodiment 2, the structure of the displacement transmission component is different from that of Embodiment 1 and Embodiment 2. This is also not necessary for those skilled in the art. Creative work can be done. The rest is the same as in Example 1.

Abstract

The motor vehicle's drive sensing device comprises a case, a drive shaft barrel, the No.1 drive shaft connected with the drive shaft barrel, and the No.2 drive shaft matched with the bearing at two ends inside the drive shaft barrel, with the drive shaft barrel connecting with the No.2 drive shaft through elastic self alignment coupler, which comprises a No.1 half coupler matched with the drive shaft barrel, the No.2 half coupler matched with the No.2 drive shaft, the rolling body between the No.1 and No.2 half couplers, and the spring base plates and spring components. On the case sets a displacement sensor, whose synchronic displacement spring base plates connected, the displacement sensor connected with the ECU of vehicles and the speed sensor on the case connected with the ECU of vehicles. While directly participating in the drive, this invention synchronically inspects the torque and speed signal with accurate signal acquisition, providing reliable data for intelligent controlled vehicles with the features of compact structure and mechanical self adaptation.

Description

Technical field [0001] The invention relates to a transmission sensing device for motor vehicles, in particular to a transmission sensing device for automobiles and three-wheeled motorcycles. Background technique [0002] Changes in torque and speed are important information of vehicle operating conditions. Therefore, the detection of torque and speed is an important part of vehicle product development, quality inspection, optimization control, working condition monitoring and fault diagnosis. There are many mature technologies for speed detection. Although torque sensors have been developed for torque detection, they have their own shortcomings for specific occasions. Common torque sensors have strain-type torque Sensors, magneto-elastic torque sensors, angle-type torque sensors and other types of torque sensors. These torque sensors cannot directly participate in the transmission. Therefore, the accuracy and reliability of the detection results are poor. The sensor and the tran...
