Front structure for use in motor vehicle, has engine cooler supported at auxiliary frame using elastic-damping unit, where resonance frequency of natural vibration of cooler is coordinated to frequency of vibrations of auxiliary frame

摘要

The structure has an auxiliary frame mounted at a front frame of a vehicle body (1), and a drive unit supported at the auxiliary frame and comprising a drive motor (3). An engine cooler (4) is supported at the auxiliary frame and at the vehicle body by using an elastic-damping unit (7), where a resonance frequency of a resonant natural vibration of the engine cooler is coordinated to a frequency of auxiliary frame`s vibrations produced by the drive motor.
