Abstract

The present invention discloses a signal bias amplification type gearbox test system based on self-gain control. The system is formed by a gearbox (1), a driving module (2) which is connected to the gearbox (1), a resistance system (3), a vibration sensor (6), a temperature sensor (5), a torque sensor (4), a torque signal processing module (8) which is connected to the torque sensor (4), a bias amplifier circuit (9) which is connected to the torque signal processing module (8) and a single chip microcomputer (7) which is connected to the temperature sensor (5) and the vibration sensor (6). The system is characterized in that a self-gain control circuit (10) is arranged between the bias amplifier circuit (9) and the single chip microcomputer (7), a torque signal is more stable through the effect of the self-gain control circuit, thus the precision of a torque test is improved, and the evaluation of the performance of the gearbox by test personnel is facilitated.

Description

technical field [0001] The invention relates to a gearbox testing system, in particular to a signal bias amplifying gearbox testing system based on self-gain control. Background technique [0002] With the rapid development of automobile industry technology, various forms of vehicle automatic transmissions have appeared one after another. Mainly include: hydraulic mechanical transmission (AT), electronically controlled mechanical automatic transmission (AMT), and mechanical continuously variable transmission (CVT). Among them, the electronically controlled mechanical automatic transmission (AMT) is being favored by various automobile manufacturers because of its simple structure, high efficiency and high cost performance. As the core component of the vehicle, the performance of the automatic mechanical transmission is closely related to the power, economy and comfort of the vehicle. The performance of the gearbox is tested through experiments to obtain the performance para...
