Hansa hydraulic pump

Innovative electronically controlled axial piston pump for hydrostatic transmissions in small-sized work vehicles. The project was funded by the Emilia Romagna Region’s 2017 call for “innovation and product or service diversification projects for SMEs” POR-FESR 2014 – 2020 Action 1.1.2 Axis 1 DGR 1339/2017

PARTNER: Hansa-TMP

Description

Software development and realization of a control prototype of a hydrostatic transmission composed of an axial piston hydraulic pump with reversible proportional control and a fixed or two displacement motor.

Objectives

GOALS: Implementation of a transmission control based on the piston pump displacement management according to the number of revolutions of the diesel engine of the machine on which the transmission is installed.

RESULTS:

Define the functional specifications for the hydrostatic transmission
Performed the analysis of the Functional Safety requirements according to the ISO 13849 standard
Identified commercial components to be used (sensors, actuators, programmable electronic control unit)
Design and implementation of BSP software (Board Support Package) with respect to the hardware chosen
Design and implementation of the embedded application software that realizes the objective functionality of the project
Design of the Can driver management software for the calibration interface
Functional validation on the test bench
