Inter-leaf friction dampens the spring's motion and reduces rebound, which, until shock absorbers were widely adopted, was a very significant advantage over helical springs. [4] However, because the leaf spring is also serving to hold the axle in position, soft springs—i.e. springs with low spring constant—are not suitable.
A multi-leaf spring consists of a series of flat plates, usually of semi-elliptical shape. The flat plates are called leaves of the spring. The leaf at the top has maximum length. The length gradually decreases from the top leaf to the bottom leaf. The longest leaf at the top is called master leaf. It is bent at both ends to form the spring eyes.
Consider the example above, where the spring rate was calculated to be 500 lbs/inch (87.5 N/mm), if one were to move the wheel 1 in (2.5 cm) (without moving the car), the spring more than likely compresses a smaller amount. If the spring moved 0.75 in (19 mm), the lever arm ratio would be 0.75:1.
Similarly, the use of one leaf spring pack for both wheels improved reliability on rough roads over competing designs that required a spring for each front wheel. In the event of a coil spring breaking the failure is total, whereas with a transverse leaf spring pack only one leaf tends to fail at one time (usually at the center mounting point ...
This new generation model also reverted to five-lug wheels from the prior generation's six-lug wheels to reduce costs and assembly times. 2006 Dodge Dakota R/T A V6 and two V8 engines were available: The standard engine is a 3.7L PowerTech V6; the two 4.7L V8 engines are the standard PowerTech V8 and the V8 High Output or HO.
A ladder frame with three beam axles, the front on leaf springs, the rear tandem on leaf springs with locating arms, was used. The M939 series uses 11:00 R20 tires with two tires per side per axle in the rear (rear tandem duals). This allows a heavy load to be carried on improved roads and most US trucks in the past have used them.
