• Automatic gearboxes of various types and spin-resistant differentials are included in the subjects of papers to be read at the conference on drive-line engineering in Jersey from April 13 to 17, as well as more conventional transmission components and related design principles. As mentioned in CM last week, the conference is being held by the Automobile Division of the Institution of Mechanical Engineers. A total of 47 papers will be presented at the conference.
Mechanical types of stepless automatic gearbox will be reviewed by Paul Groetsch, a consultant, while S. F. Burnett of Self Changing Gears will deal with fully automatic gearboxes incorporating epicyclic gearing for psv and the influence of new power units such as the gas turbine on transmission developments.
Hydrostatic fully automatic gearboxes is the subject of a paper to be presented by Dr J. G. Giles, a consultant, which makes special mention of axial-piston and vane-type systems, and one part of a paper to be read by A. J. Atkins and F. E. Ellis, of Automatic Products Group Ltd, is devoted to the future role of spiral-level gear. epicyclic units in applications to heavy commercial vehicles.
The more successful types of spin-resistant differential are outlined in a paper to be read by F. Lomax, of Borg Warner Ltd, and typical application problems are discussed.
Synchromesh mechanisms for heavy trucks are reviewed in a paper to be read by I. Rosen, P. 0. Eker, S. Ivarsson, H. Mellgren and S. Kruk, of the Swedish Volvo company, and a paper by J. Austen of Porsche will cover stress calculations and types of lubricant relating to synchromesh systems.
