Vehicle Integration, Gear Material and Heat Treatment Effects on Rear Axle Whining Noise
This paper will focus whining noise on rear axles applied in mid-size trucks.
Vehicle integration changes during development affect directly the gear noise perception, in which it may be intensified.
Also, gear material and heat treatment choices for the rear axle need to be done carefully, taking into consideration the integration changes and also the driver usage.
A lessons learned collection over the diverse aspects of a rear axle whining noise will be the basis of this paper.
