Identification of Steering Wheels Rotation Angles in Agricultural Tractors

Abstract

This paper presents methodology applied for testing and calculation of steering wheels rotation angles in IMR tractors. Importance of this methodology is in defining minimal rotation angles of steering wheels under which agricultural tractor hold basic working functions when new assembly is mounted or, in our case, with installed new drive axle. By installing new drive axle on tractors R-76 DV and R-65 DV it has been noticed that tractor construction is slightly changed within assembly of newly developed chassis. From this reason certain test was needed to define relining procedures, due to introducing newly product in production process. This paper presents some results of the testing applied.

Rad prezentuje metodologiju pomoću koje je izvršeno ispitivanje i proračunavanje uglova zakretanja upravljačkih točkova kod IMR–ovih traktora. Značaj ove metodologije je u definisanju minimalnih uglova zakretanja upravljačkih točkova pri kojima poljoprivredni traktor zadržava osnovne radne funkcije pri ugradnji novog sklopa u odnosnom slučaju novog pogonskog mosta. Ugradnjom novog pogonskog mosta na traktore R-76 DV i R-65 DV, delimično se izmenila konstrukcija traktora te je u sklopu tog novo definisanog konstruktivnog stanja, bilo potrebno obaviti određena ispitivanja definisana odgovarajućim procedurama koje se primenjuju pri uvođenju novog proizvoda u proizvodni proces. Ovaj rad upravo prezentuje neke rezultate ovakve vrste ispitivanja.
