Adopt an off-road vehicle four-wheel drive system of Automotive continuously variable transmission training bench One, five manual variable speed (with clutch assembly, clutch control mechanism, etc.); Two, transfer box assembly (with shift mechanism) 3. Rear drive shaft assembly, rear drive axle assembly (including rear axle housing, main reducer, differential speed device, left and right rear drive half shaft, left and right rear brake assembly, etc.); Four, front drive shaft assembly, front drive axle assembly (including rear axle housing, main reducer, differential speed device, left and right rear drive half shaft, left and right rear brake assembly, etc.); Five, auxiliary devices (reducer motor, reducer, leakage protection device, mobile platform, etc.) I. Automotive continuously variable transmission training bench function: The four-wheel drive drive system is arranged according to the position of the original car and reasonably connected through the mobile platform. 1, large area deep anatomy manual transmission and clutch, transfer box, front and rear drive axle, brake, different parts with different colors Logo, intuitive embodiment of manual transmission and clutch, transfer box, front and rear drive axle, brake and other external and internal structure and composition Relationship (each moving part is clearly visible); 2, intuitive embodiment: the structure and working principle of the four-wheel drive drive system of the car. Two, dynamic demonstration function: Driven by a reducer, the speed of the input shaft is 10~15 RPM.Operate the working process of the four-wheel drive drive system and demonstrate the working principle of the four-wheel drive drive system. 1, the actual dynamic demonstration clutch and shift operation, can easily change each gear, fully reflect the transmission line and manual transmission The running state of each gear; 2, the actual dynamic demonstration of the operation of the transfer box, can easily change the driving mode, fully reflect the transmission line and drive mode operation of the transfer box State; 3. Demonstrate the working condition of the Automotive continuously variable transmission training bench and the working principle of the universal joint; 4, dynamic demonstration of reducer and differential working process and working principle; 5. Dynamic demonstration of brake working process and working principle; Reasonable industrial modeling, comprehensive safety protection, equipped with mobile casters, with beautiful and generous, high safety factor, convenient and so on.
