Embodiment 1

[0030] Embodiment 1: The displacement transmission mechanism adopts a differential transformer type displacement sensor. Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12 and Fig. 13, install the transmission shaft tube 4 on the vehicle frame On the connected box body 1, cooperate with the first bearing 2 and the second bearing 3 at the two ends of the box body; the figure keypad 22 is fixedly connected to one end of the first transmission shaft 5, and the figure keypad 22 is connected with the drive shaft cylinder 4 The spline groove is matched, and the other end of the first transmission shaft 5 is connected with the input shaft 9 through a universal joint;

[0031] First put the second transmission shaft 8 with the third bearing 6 and the spring assembly 17 (composed of 6 disc springs) on the left end into the left end of the transmission shaft cylinder 4, and make the third bearing 6 and the inner wall of the tra...

Embodiment 2

[0034] Embodiment 2: The displacement transmission mechanism adopts a photoelectric-eddy current displacement sensor. Referring to Fig. 14, since the type of displacement sensor adopted is different from that of embodiment 1, the structure of the displacement transmission assembly is different from that of embodiment 1, which can be made by those skilled in the art without creative work . All the other are identical with embodiment 1.

Embodiment 3

[0035] Embodiment 3: The displacement transmission mechanism adopts a Hall-type displacement sensor. Referring to Fig. 15, since the type of displacement sensor adopted is different from that of Embodiment 1 and Embodiment 2, the structure of the displacement transmission assembly is different from that of Embodiment 1 and Embodiment 2, which is why those skilled in the art do not need to pay Creative labor can be made. All the other are identical with embodiment 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 motor vehicle transmission sensing device, in particular to an automobile and a three-wheeled motorcycle transmission sensing device. Background technique [0002] Changes in torque and rotational speed are important information on vehicle operating conditions. Therefore, the detection of torque and speed is an important part of vehicle 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, therefore, the accuracy and reliability of the detection resul...
