Transmission 700.420/421/422/423, 724.033/044/045/103/114/115/120 

Overview 

This document contains information on:

• General 
• Function 
  • Power transmission tasks 
  • Power transmission components 

General 

The engine torque generated by the combustion engine is transferred through the dual clutch interface to the dual-clutch transmission. The dual clutch transfers the power from the engine to the transmission.

Function 

Power transmission tasks 

• Bridging of the dip in engine speed caused by the K1 coupling when starting off:

  The double clutch converts the different speeds of the engine and manual transmission into a frictional connection.

• Adaptation of the torque to the driving operation:

  Due to various driving conditions, different tractive forces occur. The power transmission changes the torque at the wheels when the engine maintains a constant speed.

• Change of vehicle speed:

  Apart from torque conversion, the vehicle speed is also adapted as a result of the rotational speed conversion in the transmission.

• Safeguarding of reverse travel:

The transmission implements reverse travel.

Power transmission components 

The power transmission consists of the following components:

• Dual clutch
• Transmission
• Axle drive
• Axle drive
