AT A GLANCE
The performance of a manual or DCT automotive gearbox is typically measured by its efficiency, ease of operation and the gear change smoothness and rapidity. These characteristics must remain constant even after the millions of gear changes that occur during the lifetime of a vehicle.
To shift the gears, the gear stick in the vehicle is linked via cables to a shifting tower in the gearbox that activates the shifter forks positioned between the gear sets.
When the gear stick is moved from 1st to 2nd gear, from 2nd to 3rd gear etc., the bearings in the shifting tower and shifter forks slide on steel rails in rotational and linear movements to activate each gear change.
To ensure reliable and smooth working whether operating under dry (after a period of rest) or lubricated conditions, GGB DP4 metal-polymer composite bearings are mounted in the shifter forks and in the shifting towers.
The structure of GGB DP4 self-lubricating bearings consists of a strong steel backing, to which is bonded a porous bronze sinter interlayer impregnated and overlaid with a low friction PTFE enriched wear resistant bearing layer.
Some of the benefits obtained by using GGB DP4 self-lubricating plain bushings are the following:
Isolator Pulley Dampers
Shock Absorbers and Struts
