Hydraulic components, piping in a transparent hose, compact structure, reliable connection and no leakage.
Hydraulic components in a transparent organic glass shell as the basic, working medium for hydraulic oil, white system at work can be clearly observed that the working process of the hydraulic components of the valve core, intuitive is strong.
Box set element component, hydraulic pump station, control motor and electric control part of box, the teacher may convenient will be live demonstration equipment into classroom teaching and the physical interpretation.
The flexibility of a CVT with suitable control may allow the input shaft tomaintain a constant angular velocity even as the output speed varies. Acontinuously variable transmission (CVT), also known as a single-speedtransmission, stepless transmission, pulley transmission, or, in case ofmotorcycles, a twist-and-go, is an automatic transmission that can changeseamlessly through a continuous range of effective gear ratios. This contrast swith other mechanical transmissions that offer a fixed number of gear ratios.
The completepower flow within the CVT automatic transmission can be observed:
Primary andsecondary conical disk with hydraulic piston
Idler gearand differential
Input shaft
Planetarygear with hydraulic clutch mechanism
Speed changeby movement of the conical disks.
The transmission is mounted on a table stand. The transmission is currently used in the A and B class ofMercedes-Benz. The parking mechanism must be pushed down to allow the gearboxto rotate. By compressing the disk package the function of the clutch can beexplained. The transmission can be turned easily and the gears can bechanged by hand.

The transmissioncan be turned easily both from the drive and also from the output side. With the 5th generation of automatic transmissions, the following is achieved: high shifting comfort, light weight construction, fuel savings and increased driving enjoyment.
The following are visible:
All 7 hydraulic couplings
Range selector can be shifted
Solenoid valves and many small construction parts
Parking lock
Hydraulic control,
Converter with lock-up clutch
Ravigneaux planetary gear train and 2 simple planetary geartrains

The transmissions in the individual gear steps are not implemented with planetary gear trains, but with spur gears. In the cutaway torque converter, one sees the pump and turbine wheel, the free wheel and the converter lockup clutch. A very extensive description of the function is supplied. The shifting processes are initiated electronically, with the gears being shifted by hydraulic clutches via theelectro-hydraulic control unit.

The installation of a gearshift rod with abutton and a mechanical clamping lever means that all the gears can be shiftedand the function of the hydraulic controls demonstrated. The automated, sequential six-gear transmission developedfrom the classical six-gear manual transmission is controlled by the enginemanagement. With the help of a hydraulic piston, 2 gears can be shifted on eachshift level. In this way, the old gear is firstly removed and then the selector shaft turnedonto a different shift level by a pin in the arrested gate sleeve when theinlet selector shaft is displaced by the first hydraulic piston. To change to another shift level, a gate sleeve, which had beenable to rotate loosely up to then, is arrested by a second hydraulic piston. Now, shiftinginto the next gear is possible.
