The present invention to achieve the above object, adopts the following technical scheme that：One kind is used for automobile cardan (hookes)universal joint and is driven
The experiment teaching aid of device, including ac motor, the ac motor pass through shaft coupling and preceding axis connection, the front axle and
The actively fork connection of one universal joint, actively fork is connected first universal joint with the first universal-joint cross trunnion, first universal joint
Cross axle is connected with the first universal joint from moving fork, and first universal joint is actively pitched from moving fork by jackshaft and the second universal joint
Connection, actively fork is connected second universal joint with the second universal-joint cross trunnion, second universal-joint cross trunnion and the 20000th
Connected to section from moving fork, second universal joint is from moving fork and rear axis connection；Wherein, the first signal is provided with the front axle
Tooth, secondary signal tooth is provided with the jackshaft, the 3rd signal teeth is provided with the rear axle；Set at first signal teeth
The first tachometric survey and display device are equipped with, is provided with the second tachometric survey and display device at the secondary signal tooth, the 3rd
The 3rd tachometric survey and display device are provided with signal teeth.
Further, first tachometric survey and display device, second tachometric survey and display device and described
3rd tachometric survey is made up of with display device Hall element and revolution counter.
Beneficial effects of the present invention：The experiment teaching aid of the present invention can display automobile cardan (hookes)universal joint transmission device directly perceived
The course of work, and convenient regulation significantly improves teaching efficiency.
Brief description of the drawings
Fig. 1 is the principle schematic diagram of the present invention.
