Vehicle and driving torque measurement system thereof

Abstract

The invention discloses a vehicle and a driving torque measurement system of the vehicle. The measurement system comprises a torque transducer, a wireless launcher and a wireless receiver, and further comprises a power supply, wherein the torque transducer and the wireless launcher are arranged on a flywheel, and the wireless receiver is arranged on a flywheel housing. The torque transducer is connected with the wireless launcher in a signal mode. The power supply supplies electricity to the torque transducer and the wireless launcher. The measurement system obtains torque of an output shaft through detecting strain of the flywheel, and the torque transducer is arranged on the flywheel, does not need to be connected with the output shaft directly and is convenient to install. In addition, the wireless launcher and the wireless receiver adopt the mode of wireless transmission, signal fluctuation due to unreliable contact is avoided, and therefore the torque transducer is transmitted to a gathering module accurately in real time. Due to large inertia of the flywheel, compared with an engine or a gearbox, the flywheel is stable in state, and the work environment of the torque transducer is stable, and therefore the fact that the accurate real-time measurement is carried out on driving torque is possible.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a vehicle and a running torque measurement system thereof. Background technique [0002] The current world energy situation has had a great impact on the automotive field. Energy conservation and emission reduction has become the focus of major automobile manufacturers and consumers. In order to achieve this goal, it is necessary to understand the working environment and vehicle condition information of the vehicle. To collect and analyze the relevant parameters of the vehicle, the driving torque is a key parameter, and the data collection requires high precision and strong reliability. [0003] The existing torque measurement methods mainly include the following two types: [0004] 1) Install a torque sensor on the output shaft of the gearbox for measurement [0005] Torque is the output torque of the vehicle. This torque parameter can be obtained by detecting th...

AI Technical Summary

Problems solved by technology

[0009] Although the test bench can simulate the actual running situation to a certain extent, it is not comprehensive. In many cases, it cannot show the actual working condition of the vehicle, that is, it cannot be measured in real time, and the measured torque cannot accurately reflect the actual driving torque of the vehicle.

In addition, when measuring with a dynamometer, the data may be distorted due to poor contact
