Abstract

A system for a utility vehicle has a compressor, an electric motor and an electronic drive system. The electric motor drives the compressor. The electric motor, the compressor and the electronic drive system have a common cooling circuit.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A system for a utility vehicle, comprising:
 a compressor;   an electric motor; and   an electronic drive system, wherein   the electric motor drives the compressor, and   the electric motor, the compressor and the electronic drive system have a common cooling circuit.   
     
     
         2 . The system as claimed in  claim 1 , wherein
 the compressor is a screw compressor.   
     
     
         3 . The system as claimed in  claim 1 , wherein
 the common cooling circuit has a coolant duct which is formed for at least a portion by a succession of cooling elements.   
     
     
         4 . The system as claimed in  claim 3 , wherein
 at least one cooling element is coordinated, respectively, with the electric motor, the compressor and the electronic drive system.   
     
     
         5 . The system as claimed in  claim 4 , wherein
 the electric motor has a stator cooling element, wherein the cooling elements are arranged such that coolant in the common cooling circuit flows at first through a cooling element of the electronic drive system, then through the stator cooling element, and then through a cooling element of the compressor.   
     
     
         6 . The system as claimed in  claim 5 , wherein
 the electric motor further comprises a housing cooling element, wherein the cooling elements are arranged such that coolant in the cooling circuit flows at first through the housing cooling element upstream from the cooling element of the electronic drive system.   
     
     
         7 . The system as claimed in  claim 4 , wherein
 the cooling element of the electronic drive system comprises a flow divider.   
     
     
         8 . The system as claimed in  claim 7 , wherein
 the cooling element of the electronic drive system comprises a substantially W-shaped flow duct.
