UPGRADED STAND FOR TESTING OF HYDRAULICALLY ASSISTED STEERING BOXES FOR CARS.

An economic partner wanted to improve a test bench for testing hydraulic assisted power steering and pumps for passenger cars and vans. Modernization of existing technology through computerization will reduce testing time and diminish the consumption of electricity, but also eliminate any human error which may occur in the verification process of repair; in this way there is the certainty of a subassembly that provides full security to the user. For upgrading, a number of subassemblies have been installed on the stand that allow the stand to be interfaced with a computer. The subassemblies consist of a series of transducers, electronic block, a data acquisition board and a drive system for the steering box valve. The paper presents the construction and functioning of the necessary subassemblies for stand upgrading and their characteristics. [ABSTRACT FROM AUTHOR]
