SDMHE (Self Deployable Materials Handling Equipment) Driveline Benchtest

Abstract

The purpose of testing was to evaluate the acceptability of existing driveline components for use in the U.S. Army's proposed Self Deployable Materials Handling Equipment (SDMHE). The proposed SDMHE differs from past and present Rough Terrain Forklifts in that it must be capable of 45 miles per hour transport speeds. The driveline components tested were selected based upon ability to meet the required SDMHE performance specification, availability, cost, and reliability. Test results indicate that engines, torque converter power shift transmissions and drive shafts do presently exist which would perform acceptably on the SDMHE. Test results indicate that existing axle assemblies which will perform acceptably on the SDMHE may be more difficult to find. The two major problems found on the tested axle assembly were (1) excessive oil temperature during high speed transport and (2) inadequate gear train strength during materials handling operations. Keywords: Rough terrain, Forklift, Self deploy, Drive train, Bench tests, Axles, Powershift transmission.
