Despite significant improvements in automatic transmissions in recent years, manual gearboxes are still most European users' default choice. Andrew Noakes asks if a shift to new transmission concepts can change that  01/11/2008  Double the benefits Ian Adcock reports on Porsche's nw seven-speed dual clutch AMT that, uniquely, has separate oil systems for clutches and gears  01/08/2008  Torque it up Asymmetrical distribution of drive and brake torques is the way forward for handling and safety, says Andrew Noakes  01/06/2008  7 speed world beater Roger Bishop takes a look inside Volkswagen's new seven-speed DSG and discovers the design secrets behind the lightweight, agile transmission  01/02/2008    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.  01/11/2007    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  01/10/2007    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  01/09/2007    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  01/09/2007    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.  01/05/2007    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.  01/05/2007    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.  01/03/2007    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.  01/02/2007    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.  01/09/2006    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.  01/06/2006    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.  01/02/2006    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.  01/02/2006    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.  01/04/2005    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.  01/03/2005    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.  01/11/2004    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.  01/11/2004    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.  01/10/2004    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.  01/10/2004    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.  01/10/2004    Torque-coupling differential is programmed to perform Dana has developed an electronic torque-coupling differential for all-wheel-drive vehicles.  01/10/2004    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.  01/09/2004    Showing 1 to 25 out of 25 results	Magazine Services    Apply for free copy  Reader Enquiry Service     Sponsored Links
