Example Embodiment

[0022] Such as figure 1 , figure 2 with image 3 As shown, the transmission shaft with a torque device capable of real-time online monitoring of the present invention includes a shaft 1. The middle of the side wall of the shaft 1 is provided with a mounting groove 2 for installing electrical components, and the mounting groove 2 surrounds the side of the shaft 1. The wall has a circular ring shape. The installation groove 2 is provided with a Wheatstone bridge 3 including metal resistance strain gauges. The two half-bridge strain gauges of the Wheatstone bridge 3 are respectively attached to the bottom of the installation groove 2 axially symmetrically. Each half-bridge strain gauge includes two resistance strain gauges. The electrical signal output end of the Wheatstone bridge 3 is electrically connected to the electrical signal input end of the signal amplifier 4, and the electrical signal output end of the signal amplifier 4 is electrically connected to the analog-to-digital...

Abstract

A transmission shaft with a real-time online torque monitoring device comprises a shaft rod, wherein an installing groove for an electrical apparatus element to be installed is formed in the middle of the side wall of the shaft rod and is in a shape of a circular ring around the side wall of the shaft rod. A Wheatstone bridge is arranged in the installing groove, the electric signal output end of the Wheatstone bridge is electrically connected with the electric signal input end of a signal amplifier, the electric signal output end of the signal amplifier is electrically connected with the electric signal input end of an analog-digital converter, the electric signal output end of the analog-digital converter is electrically connected with the electric signal input end of a radio transmitting module, the radio transmitting module sends a signal to a radio receiving module, and the radio receiving module is connected with a computer capable of processing, displaying and storing a torque value transferred by the transmission shaft. The transmission shaft with the real-time online torque monitoring device can achieve online torque monitoring in a narrow space in a high-temperature and high-vibratory-impact environment and is stable and reliable in working performance and high in measurement accuracy.

Description

technical field [0001] The invention relates to a transmission shaft with a torque device capable of real-time on-line monitoring. Background technique [0002] The transmission shaft is one of the key components of many transmission systems including the vehicle transmission system. It is very important to know the load transmitted by it to monitor the operation status of the transmission system such as vehicles; on the other hand, the long-term or full Life monitoring can provide powerful technical means for the development of new models of transmission systems such as vehicles, and play an important role in promoting the development of key components such as vehicles. The traditional approach is to install a torque testing system at an appropriate position (such as the exposed part) of the transmission shaft after the vehicle is developed and produced to realize online testing of the torque. However, due to the compact structure of the vehicle power transmission system, ...
