Low Vibration and Noise Body
Low Vibration and Low Noise Body1. General
An effective application of vibration damping and noise suppresant materials reduces engine and road noise.
2. Sound Absorbing and Vibration Damping Materials
^ A dash silencer, sandwich panel, and an inner dash silencer have been adopted in the dash panel area to improve sound insulation performance.
^ Spray-on damping material has been adopted on the floor to improve vibration damping performance.
^ Foamed materials and urethane pad damping materials are allocated throughout the vehicle. As a result, the wind and road noises that are transmitted to the rockers and pillars have been reduced.
^ Damping materials are provided on the cowl panel to reduce the transmission of the engine noise.
^ A fender seal is provided in the front fender to reduce wind noise.
3. Cab Mounting
^ The mounting construction of the cab mounts has been optimized. Accordingly, the vehicle's riding comfort has been improved and noise and vibration have been reduced.
^ The mounting construction of the No.1 cab uses a type that is surrounded by a panel. The No.2 to No.4 mountings are the collar construction type.
