Creeping motion
traction drive pump at full rotation speed. Creeping motion can act on the brake if the creep pedal is used to cancel the brake pressure (again via the pivoting angle associated with the pump).
Secondary measures (in the case of sound)
Sum of all measures, which the system designer must take for a given pump (motor) to produce a quiet system (see noise creation in hydraulic systems). Specifically, this means: measures, which can reduce [...] transmission of structure-borne noise. This relates primarily to the oscillation-insulated assembly of the pump to prevent the bodies which can oscillate greatly, such as oil drums and the assembly wall, amongst
Tank
(Table B 1) . As the tank is manufactured of thin material, it must not be in physical contact with the pump to prevent noise propagation. Tanks mostly have a breather filter that connects them to the exterior [...] are used that are pressurised to 0.3 to 0.6 bar using compressed air to improve the filling of the pump. In this case, a rubber diaphragm is recommended as a separating wall ( precharged tank).
Pre-charge container
(3 to 6 bar) to create a traverse speed in the case of large cylinders, for which there is no more pump for rapid traverse . The pre-charge container is refilled with the reflux oil after each stroke (
Spherical cone
Pump piston with a spherical piston surface, which contains piston rings for sealing. The piston shaft is lowered ( Figure S 75 ). The spherical piston is used in axial piston machines, in which the cylinder
Automatic control
Control of a vehicle with hydrostatic drive by operating the pump as a function of the accelerator pedal for the combustion engine and therefore its rotation speed. Pulling away is therefore gentle and
Utilisation factor
Measure for the usage of a device (e.g. a pump) during a working cycle. The basis for determining this parameter is the sequence diagram for the installation. The utilisation factor plays a role in the
Hydrostatic drive
hydrostatic drive associated with a load, but also more generally the chain of effects involving hydraulic pump control hydraulic motor ( cylinder ), including the associated accessories (Figure H 19) , as well
Power transmission
electrical (current · voltage) from the generating part of a system (e.g. electric motor, hydraulic pump) to the motor part (e.g. cylinder , motor) in the power section of a system.
Multi-circuit systems
Hydraulic drive system in which several circuits operate separated from each other, with each having a pump and associated pressure-limiting valve . These kinds of multi-circuit systems may be designed in such
