The Case for Mechanical Transmissions in On-Off Highway Trucks

The on-off highway truck must serve two primary purposes. It must be capable of going into adverse terrain to pick up a load and be able to bring the load out to improved private roads or public highways. It must then have relatively high speed highway capabilities in order to keep round trip time to a minimum. This paper discusses the transmission requirements for this truck and presents a case for selecting a mechanical transmission to serve these purposes.
