3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Overturning stability staticinclinationstability
Under static conditions, the tractor inherent resistance to longitudinal (side) when the ability to tilting.
3.2
Vertical (side) inclination to turn longitudinal (lateral) inclinationangle
Tractor wheel support angle with the horizontal plane.
3.3
The maximum longitudinal tilting angle stable maximumangleoflongitudinalstability
In overturning the bench, tilt tractors, two wheel tractors support plane normal reaction force to zero (or away from the support surface) when turning
inclination.
3.4
Maximum lateral tilting angle stable maximumangleoflateralstability
In turn overturning test stand, tilt tractor, tractor either side of the wheel support plane normal reaction force to zero (or away from the support surface) when
inclination.
