Bosch Rexroth’s Hydrostatic Function Module
Safety function and innovative features improve the overall efficiency of the traveling machinery.With Bosch Rexroth’s functional modules, vehicle manufacturers can significantly reduce their costs when using hydrostatic drive systems. The function block incorporates innovative features and standard safety features to meet the requirements of the Machinery Safety Directive. In addition, Bosch Rexroth developers also studied the relationship between all the components to further enhance the reliability of the function module.Significantly lower integration costs, a robust hydrostatic drive solution that combines functional safety and innovative features to meet relevant standards.
Bosch Rexroth conducts a risk analysis of the functional modules and selects the required performance levels for the application according to the relevant criteria, such as performance level b, performance level c and class C standards, so that the vehicle manufacturer can significantly reduce the cost . The standard hardware and software configuration of the function module meets the above performance levels. In addition, developers are also based on the FMEA, to determine the system components of the relationship. The system load is determined based on the actual load measured in the numerous applications, and the system components are adjusted accordingly to further enhance the reliability and availability of the functional modules in practice. Bosch Rexroth’s functional modules help improve the performance of hydrostatic drive units for vehicle manufacturers wishing to enter the European market for mobile machinery, in accordance with the local machinery safety guidelines.
Hydrostatic travel control with standard safety functions is integrated in the DRC drive software. Vehicle manufacturers can spend a lower cost of engineering for wheel loaders or telescopic forklifts equipped with new drive solutions. The “2 + 1” travel drive module reduces fuel consumption by up to 20% without causing traction interruptions. The diesel engine with a maximum output of 130 kW drives the axial piston pump, which is connected to the variable motor and the dosing motor. Drive range is automatically adjusted to achieve a maximum speed of 40 km / h. The integrated software of the control unit avoids situations where the traction force is zero and significantly enhances the operator’s comfort. The function module for the weight of 6 to 16 tons, traction does not exceed 120 kN walking and agricultural machinery.
The “Power Shift” function meets the safety requirements of DIN EN ISO 13849 for manual and automatic switching. Bosch Rexroth has integrated the optimized switching strategy in the software, and can realize the safe switch under different driving situations. Short synchronized switching operation enhances comfort. This function module is equipped with hydraulic pump, hydraulic motor, presetting software control unit and transmission box, can improve the efficiency of the entire drive system. The “2 + 1” and “Power Shift” functions cover a wide range of power through a combination of pump and motor sizes.
In addition, Bosch Rexroth also helps compact walk-behind and wheel loader manufacturers reduce noise emissions with hydraulic start-stop HSS. The function module automatically shuts off the diesel engine when the vehicle is stationary and automatically restarts when necessary using the previously stored hydraulic energy. Supply the required torque immediately. The solution consists of axial piston variable pumps, valves, compact accumulators and BODAS control units with preloaded software.
