Abstract

A system for a utility vehicle has a screw compressor and an electric motor. The electric motor drives the screw compressor. The electric motor is connected to the screw compressor by a flange which has at least one cooling connection, and a cooling channel is provided in the flange.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A system for a utility vehicle, comprising:
 a screw compressor; and   an electric motor, wherein the electric motor drives the screw compressor; and   a flange, wherein   the electric motor is connected to the screw compressor by the flange,   the flange has at least one cooling port, and   at least one cooling channel is provided in the flange.   
     
     
         2 . The system as claimed in  claim 1 , wherein
 the flange is a separate component arranged between the electric motor and the screw compressor.   
     
     
         3 . The system as claimed in  claim 2 , wherein
 a drive shaft for driving the screw compressor by the electric motor is guided in the flange.   
     
     
         4 . The system as claimed in  claim 1 , wherein
 cooling fluid for the flange is water-based, wherein use is made of cooling water or a mixture of water and a further component.   
     
     
         5 . The system as claimed in  claim 4 , wherein
 the further component is methylene glycol.   
     
     
         6 . The system as claimed in  claim 1 , wherein
 the screw compressor is configured to generate compressed air.   
     
     
         7 . The system as claimed in  claim 1 , wherein
 the electric motor has an electric motor flange which is provided for the connection to the flange.   
     
     
         8 . The system as claimed in  claim 1 , wherein
 the at least one cooling channel of the flange is open in a direction of the electric motor flange with regard to the assembled arrangement.   
     
     
         9 . The system as claimed in  claim 1 , wherein
 a seal of the cooling channel is formed for the first time in the assembled state as a result of the assembly of the electric motor flange and the flange.   
     
     
         10 . The system as claimed in  claim 1 , wherein
 the electric motor or the electric motor flange has no cooling channel and/or no coolant ports.
