Abstract
CURRENT production transmission designs offered by the world's eight leading bus manufacturers are reviewed in this paper. It includes illustrations and brief descriptions of the following: electrical propulsion; semi-automatic planetary transmissions; fluid flywheels; hydraulic transmissions with both manual and automatic controls; synchromesh transmissions; transmissions other than synchromesh, automatic or semiautomatic; and methods of providing drive between transmissions and rear axles for American vehicles with transversely mounted rear and underfloor engines.
The discussion is restricted to transit-type buses since vehicles with engines out in front under any form of hood are, in so far as concerns American practice, practically extinct.
The paper is largely a review of current American practices, and it is believed that the explanatory data, together with the illustrations, will permit those interested to compare readily the different methods employed.
