The input torque (i.e. from the engine or transmission) is applied to the differential via the rotating carrier. [8] Pinion pairs are located within the carrier and rotate freely on pins supported by the carrier. The pinion pairs only mesh for the part of their length between the two spur gears, and rotate in opposite directions.
Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via jury evaluations, or with analytical ...
Thrust bearings are used in cars because the forward gears in modern car gearboxes use helical gears which, while aiding in smoothness and noise reduction, cause axial forces that need to be dealt with. Thrust bearings are also used with radio antenna masts to reduce the load on an antenna rotator.
False brinelling of a bearing. False brinelling is a bearing damage caused by fretting, with or without corrosion, [1] that causes imprints that look similar to brinelling, but are caused by a different mechanism. False brinelling may occur in bearings which act under small oscillations [2] or vibrations. [3]
The outer end of the lower link pivots about a fulcrum shaft, which runs longitudinally through the bottom of each hub carrier. The inner fulcrum mounting is adjacent to the bottom of the differential casing. Wide spacing of the pivot bearings provides both torsional and fore-and-aft rigidity to the hub carrier.
The first thing to fail will be cam carrier bearings if the vehicle is OHC as this is fed through a restrictor and low pressure will starve the top of the engine of lubrication. If pistons have crown jets (e.g., scania), this could cause piston/liner nip. Also the crankshaft and connecting rod bearings may seize.
Torsional vibration is a concern in the crankshafts of internal combustion engines because it could break the crankshaft itself; shear-off the flywheel; or cause driven belts, gears and attached components to fail, especially when the frequency of the vibration matches the torsional resonant frequency of the crankshaft.
The kingpins were now fixed to the axle ends and the hub carriers pivoted upon them. Most commonly the centre of the kingpin was fixed in the axle and the hub carrier was forked to fit over this, but some vehicles, including the Ford Model T illustrated, used a forked axle and a kingpin fixed into a single piece carrier.
