The Dana 44 rear axle first saw use in the 1940s and is still in use today. The Dana 44 has a GAWR up to 3,500 lb (1,600 kg) and is a semi-floating type, having one bearing on the end of the axle shaft which carries the weight of the vehicle on the axle and also allows axle rotation.
The pivot bearings at each end of the lower link are widely spaced so as to provide maximum longitudinal rigidity. Suspension is provided by two coil spring and damper units (yellow) on each side of the differential casing (four in total), the spring and damper units attaching to the crossbeam at the top and the lower link at the bottom.
The Dana 80 Trac Lok is unique being it is a 4 pinion unit, unlike other Dana Trac Lok units with 2 pinions. This was the only rear axle available for the 2nd generation Dodge Ram 3500 trucks. [2] 35 Spline Dana 80 in a 2002 Dodge 2500HD Diesel
A swing axle is a simple type of independent suspension designed and patented by Edmund Rumpler in 1903 for the rear axle of rear wheel drive vehicles. This was a revolutionary invention in automotive suspension, allowing driven (powered) wheels to follow uneven road surfaces independently, thus enabling the vehicle's wheels to maintain better ...
The remaining length of a given pinion meshes with the nearer spur gear on its axle. Each pinion connects the associated spur gear to the other spur gear (via the other pinion). As the carrier is rotated (by the input torque), the relationship between the speeds of the input (i.e. the carrier) and that of the output shafts is the same as other ...
The major disadvantage of the multiple sprocket freewheel design is that the drive-side bearing is located inboard of the freewheel, and as sprockets were added over time, the bearing moved inward, farther from the drive-side axle support. This resulted in more flexing stress being placed on the axle, which can bend or
Anti-roll bar (in red) attached to a front axle. The bar must also have its two longitudinal anchor points fastened solidly to transfer forces from side to side. An anti-sway or anti-roll bar is intended to reduce the lateral tilt (roll) of the vehicle on curves, sharp corners, or large bumps.
In many cases, such as remote controlled toys, the pinion is also the drive gear for a reduction in speed, since electric motors operate at higher speed and lower torque than desirable at the wheels. However the reverse is true in watches, where gear trains commence with a high-torque, low-speed spring and terminate in the fast-and-weak escapement.
