New energy vehicle gear detecting device and detecting method thereof

The invention discloses a new energy vehicle gear detecting device and aims to solve the problem that a gear of a new energy vehicle is difficult to effectively detect and a control logic is cumbersome in the prior art. The new energy vehicle gear detecting device comprises a substrate, an upper side of the substrate is provided with a motor controller and a motor, and an output end, which is a power shaft, of the motor is connected to a first shaft of a speed reducer through a coupling. A gear to be detected is welded and fixed on the first shaft and engages with a standard gear, the standardgear is welded and fixed on a third shaft, a monitoring wheel is welded and fixed on the other end of the third shaft, and the bottom of the monitoring wheel is provided with a monitor which analyzesthe performance of the gear to be detected to achieve the detection of the gear of the new energy vehicle. The cost is reduced while the popularization and application of the device are facilitated. 本发明公开了种新能源汽车齿轮检测装置，为解决现有技术
