NTC-15.39.3 “General and step-by-step testing and diagnosis of car steering control with hydraulic semi-integral booster”

Unlike NTC-15.39.2 this stand allows to carry out one additional laboratory work regarding general investigations of hydraulic booster (with simulation of resistance of controllable wheels to turning). 

Hydropanel and measuring and control panel are located on the stand framework, which is carried out as single-sided basis with a table. Elementary hydraulic diagram of the stand is located on measuring and control panel. Hydraulic facilities and instruments are installed on the table, on the hydropanel and on the lateral surface of the stand. Structural diagrams of investigated hydraulic booster facilities are located on the hydropanel.

Hydro station included to complete set is carried out as a separate module.

The main facilities mounted on the stand and hydro station are:

• three-phase asynchronous motor;
• gear pump;
• pressure filter;
• discharge hydraulic valve (2 pcs.);
• controllable throttle;
• hydraulic cylinders (2 pcs.);
• steering device with hydraulic distributor;
• three-port flow control valve (flow valve and pressure valve);
• resistance of controllable wheels to turning simulator;
• hydraulic booster malfunction simulator.

The stand has flexible configuration. Needed configuration of investigated subsystem is assembled with usage of elastic pipeworks with quick-release couplings (QRC). 

Information-measuring system of the stand allows to register pressures, flow rates, temperature, time. Five microprocessor pressure sensors, one manometer, two integrating flowmeters (velocity flowmeter and volume flowmeter), electronic stop-watch are installed on the stand. Pressure measurement results are displayed in digital mode. 

The training system is accompanied with a set of teaching materials and technical documentation intended for the teaching staff.
