  Hybrid ring takes hydraulics out of continuously variable transmissions
A new type of high-friction, dry-running drive belt for continuously variable transmissions (CVTs) will be of intense interest to designers of compact cars as it eliminates the need for hydraulic pumps and high oil pressures, writes Roger Bishop.

  Tyre technology rolls onwards
Tyres are becoming high-tech components, the latest of which can measure forces within their structures and integrate directly with safety systems. Jeff Daniels reports on developments in rubber and electronics

  Show and tell
Europe’s biggest car show takes place in Frankfurt from 13 to 23 September. We look beyond the gloss of the show cars and concepts to preview some of the technologies that will be on display

  A shift in fortunes for the automatic transmission
The conventional torque converter/epicyclic gearset automatic gearbox could soon be consigned to the dustbin of history as more efficient alternatives overtake it. Jeff Daniels looks at the competition

  Powerful algorithms written to simplify future DCT control
A new player in the dual clutch transmissions (DCT) field, Vocis Driveline Controls, has developed a control system it claims will bring vehicles to market more efficiently and help vehicle OEMs to match the feel of their transmissions to their vehicle brands.

  OEMs pursue latest Zeroshift transmission
A second generation Zeroshift transmission uses a new drive ring system, combined with other developments which the developers say will reduce cost, weight and packaging volume as well as improving durability, fuel economy, emissions and refinement.

  Torque vectoring prototype revealed in Germany
The latest generation of a cross-axle torque vectoring system that enables moment-by-moment redistribution of drive-torque in response to driver demand, vehicle speed and road conditions has been demonstrated to an audience of technologists in Germany, writes Roger Bishop.

  Slick and quick
Redesigning the mechatronic systems, including the hydraulic controller, allowed ZF to massively speed up the response time of its six-speed auto box as well as boosting the torque handling, writes Roger Bishop.

  Sliced spheres cut size and maintain bearing loads
Bearing elements that are spherical, but with their sides cut off, maintain axial load handling despite a big reduction in bearing width and mass, writes Tom Shelley.

  Actuator gives wet PSG the edge
At first sight it is not obvious how LuK’s ‘wet’ PSG (parallel shift gearbox) differs from other dual clutch systems currently in use or under development, writes Roger Bishop. But closer examination reveals an actuating mechanism that appears to have massive advantages over high pressure hydraulic systems.

  Wedge ramp on thread locks fasteners
The differential unit inside the high-torque front-axle Dana provides for truck and SUV OEMs is a safety critical assembly. Because its ring gear carries so much torque from the driveline its fasteners must be failsafe against shock, torque, vibration and temperature for the life of the vehicle.

  Six-speed seamless shift prototyped
A six-speed gearbox designed specifically for Zeroshift – a seamless, instantaneous means of changing gear without interrupting torque to the driveline – will be complete in a matter of weeks, writes John Mortimer.

  Tandem bearings set to transform rear axle drives
Double-row angular contact ball bearings – sometimes called tandem ball bearings – are now being incorporated into rear axle drives for passenger cars for the first time.

  High torque brings active clutch servos
The torque output of 1.8 to 2.5 litre diesel engines has almost doubled in the past 25 years with a consequent need to increase the clamping force required of the clutch to transfer the engine torque to the transmission, writes Roger Bishop.

  Truck axle is stronger and lighter
ArvinMeritor has released first details of a lighter, stronger front drive axle for European truck applications. The MS-17X single reduction solo drive axle will be available from the beginning of 2006 for OEMs.

  Axle optimises force distribution
DaimlerChrysler’s DCA (durable compact axle) system integrates axle tube, trailing arm suspension beam and air bellows support and brake carrier, reducing its overall height and allowing more volume for the trailer body. It is also said to be the lightest axle in its class.

  Output retarder smooths citybus transmissions
Fully automatic powershifting transmissions, said to be specially designed for the demands of city and suburban buses, have been launched by Allison Transmission.

  P/M technology targets heavy duty gears
Warm compaction and surface densification, used in combination, are helping to push powder metal (P/M) technology towards the high strength and fatigue properties required for transmission gears, writes Roger Bishop.

  Light, malleable materials are key to new dual mass flywheel
A new lightweight dual mass flywheel (DMF) uses a unique ‘flexplate’ technology creating what is described as a soft connection with the crankshaft to minimise loading, writes Roger Bishop.

  Torque-coupling differential is programmed to perform
Dana has developed an electronic torque-coupling differential for all-wheel-drive vehicles.

  Lean steels improve gearbox NVH
New ‘lean alloy steels’ are said to enable the gearbox industry to predict and limit the impact of distortion in the manufacture of transmissions. This should help it produce gearboxes and shafts with improved NVH characteristics at lower cost.
