Title:
ON-VEHICLE STRUCTURE OF INVERTER
Document Type and Number:
Japanese Patent JP2015002610
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress influences of noise generated by an inverter upon radio regarding an inverter on-vehicle structure supporting the inverter on a motor unit.SOLUTION: In an inverter on-vehicle structure, an inverter 6 is mounted to a case 3a of a motor unit 3 via a vibration-proof member 9 formed by overlapping coil springs which are wound inversely to each other. Each of the coil springs are conducted with both the case of the motor unit and the inverter, and the coil springs are insulated from each other. When a noise current flows in two coil springs, induced magnetic fields are canceled by each other, thereby reducing inductance. A noise current which is propagated from the inverter to the motor and returns from the motor to the inverter via the case of the motor unit and the vibration-proof member can be increased, such that a noise component to flow to a body ground with the high risk of influences upon radio can be reduced as a result.
