The smoke exhaust propulsion cylinder 1002 is arranged on the top outer wall of the workbench 7, and a quick-connect copper head 1001 is installed at one end of the smoke exhaust propulsion cylinder 1002.

[0027] Based on the above-mentioned structural features and connection relationship, the shaft of the eddy current brake 407 is connected to the shaft of the torque and speed tester 405 through a double diaphragm coupling 406, and on the same concentric line, the torque and speed tester 405 is connected to the output shaft secondary shaft of the engine through a flexible coupling 402 and a telescopic connecting shaft 401, and on the same straight line, the operating cabinet 1 includes a PLC electrical control system, an engine starting ignition device and a data recording system of the host computer, the left automatic holding mechanism 2 and the right automatic holding mechanism 3 simultaneously advance the Y-axis and X-axis clamping, and at the same time, the exhaust mechanism and the quick connector 10 are finally automatically connected to the exhaust port of the engine.

[0028] When the off-road motorcycle power loading test bench of this scheme is working, when testing is required, the engine is moved to the base surface of the engine positioning plate 601 by the power arm manipulator, and the clamping button on the operating cabinet 1 is pressed. The left X-axis clamping cylinder 202 pushes the left automatic holding mechanism 2 to move inward and stops after reaching the limit. At the same time, the right X-axis clamping cylinder 303 pushes the right automatic holding mechanism 3 to move inward and stops after reaching the limit. When the left and right holding mechanisms move into place, the dual signal is triggered, and then the middle propulsion cylinder 602 pushes the engine positioning slide 6 to start Move inward. When the engine positioning slide 6 is in place, the hanging hole on the inside of the engine fits into the left positioning pin 205 and the right positioning pin 306.

The braking force of the eddy current brake 407 is adjusted according to the preset value in the host computer system to simulate the load capacity of the real-time road. Different engines correspond to different currents. The eddy current brake 407 generates different braking forces according to different current sizes. The braking force is connected to the central shaft of the torque and speed tester 405 through the flexible coupling 402, and generates a load force on the engine. The generated speed and torque data are transmitted to the monitoring screen of the host computer in real time and compared with the standard data range in the host computer in real time. If the data exceeds the required value, a red warning will be displayed, reminding you to debug the faulty part of the engine. A sound sensor is attached to the engine to compare the sound of a normal engine. If the sound comparison is abnormal, it is determined that there is a problem with the internal assembly of the engine and it needs to be repaired, etc., thereby solving the problem of being unable to simulate loading during the off-road motorcycle engine power test.
