Holder assembly for power electronic unit in e.g. electrical passenger car, has fastening element designed as screw and holding electrical component at engine via decoupling elements in vibration decoupled manner

摘要

#CMT# #/CMT# The assembly has a fastening element for holding an electrical component at an internal combustion engine in a vibration decoupled manner via decoupling elements (44, 48). The decoupling elements are arranged between the electrical component and the engine. An electrically-insulating element is arranged between the decoupling elements and the engine. The fastening element is designed as a screw (30) with a screw head (34) and a screw shaft that is connected with the screw head. The decoupling elements are made of aluminum or aluminum alloy and stainless steel or stainless steel braided fabric. #CMT# : #/CMT# The decoupling elements are designed as damping elements. #CMT#USE : #/CMT# Holder assembly for an electrical component i.e. power electronic unit, which is utilized in an electric vehicle i.e. electrical passenger car, and at an internal combustion engine i.e. petrol engine, of a hybrid vehicle (all claimed). #CMT#ADVANTAGE : #/CMT# The fastening element holds the electrical component at the internal combustion engine in a vibration-decoupled manner via the decoupling elements, thus enabling favorable holding of the electrical component at the internal combustion engine, and reducing installation space required for the holder assembly to avoid occurrence of package problems in an engine compartment of a motor vehicle. The assembly avoids undesirable excitation of the electrical component to oscillate and vibrate and to produce an undesirable load on the electrical component. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic perspective view of a power electronics module. 12 : Housing 24 : Holder 30 : Screw 34 : Screw head 44, 48 : Decoupling elements.
